A strong hydraulic pump choice matches your mower’s exact model and stamped or listed part number, making this roundup useful for owners replacing a failed pump or servicing a hydrostatic system. Hydro-Gear’s PG-1GNP-DY1X-XXXX leads because its listing connects it to OEM 103-1942 and BDP-10A-414 and names compatible Toro and Exmark mower models. Other entries target specific Toro, Exmark, Scag, and Wright applications, while two products are charge-pump kits for Hydro-Gear transaxles rather than complete mower drive pumps.
That distinction matters: a familiar brand or similar-looking housing is not proof of fit. Compare replacement numbers and compatible models before ordering, and treat kit listings as repair components rather than direct substitutes for every hydraulic pump.
The Hydro-Gear PG-1GNP-DY1X-XXXX is the best overall choice in this set for buyers whose mower uses OEM 103-1942 or BDP-10A-Its listing names Toro and Exmark applications, including Exmark Lazer Z HP and Lazer Z CT, giving buyers specific part-number and model references to verify. If your mower instead requires another number, such as 116-2444 or 482644, choose the matching application-specific pump rather than assuming this model will fit.

Detailed Reviews: Best Hydraulic Pump For Lawn Mower
#1 · Best Overall
1. Hydro-Gear PG-1GNP Pump
Best for: Toro and Exmark BDP-10A-414 fit.
Why it ranks #1: Replaces OEM 103-1942 and BDP-10A-414, with listed Toro and Exmark applications including Lazer Z HP and Lazer Z CT.
The Hydro-Gear PG-1GNP-DY1X-XXXX explicitly replaces BDP-10A-414 and OEM number 103-1942, giving owners of listed Toro and Exmark mowers a clear cross-reference. Its stated applications include Exmark Lazer Z HP and Lazer Z CT, making it a targeted option rather than a general-purpose mower pump.
The replacement references include Hydro-Gear BDP-10A-414, Exmark 103-1942, Toro 103-1942, and STENS 025-011, which support comparison with an existing pump or parts record. Named applications include Exmark Lazer Z HP and Lazer Z CT, alongside a lengthy list of Toro model numbers. Those identifiers can help narrow fitment before repair, though the broad Toro list makes checking the exact model especially important. The listing specifies the Hydro-Gear model number but provides no dimensions or installation details.
- Replaces Hydro-Gear BDP-10A-414
- References Exmark and Toro OEM number 103-1942
- Names Exmark Lazer Z HP and Lazer Z CT
- Provides an extensive list of Toro model numbers
- The long Toro application list requires an exact model-number check.
Skip it if you need a Toro Z500 pump for 60- or 72-inch decks; Leyuncot PK-BGAB-EY1X-XXXX lists that application.
This fits shoppers tracing a pump to BDP-10A-414 or 103-1942 and owners of the named Toro and Exmark applications. Because the Toro fitment list is extensive, match the mower's exact model before selecting it.

2. Hydro-Gear PK-BGAB Pump
Best for: Hydro-Gear Exmark cross-reference.
Why it ranks #2: Hydro-Gear replacement for Exmark pumps with OEM references 116-2444, 103-7262, and PJ-BGAB-EY1X-XXXX.
The Hydro-Gear PK-BGAB-EY1X-XXXX directly references 116-2444, 103-7262, and PJ-BGAB-EY1X-XXXX, giving Exmark owners several part numbers to compare during replacement planning. Its listing also identifies aluminum as the material and gas-powered lawn mowers as the stated operating application.
The OEM cross-references provide a practical starting point for checking whether this pump corresponds to the part being removed. The listing names Exmark lawn mowers and gas-powered mower compatibility, but does not specify individual Exmark models or serial ranges. Aluminum is the material stated in the specifications, while the feature text also describes stainless-steel construction; the listing therefore presents conflicting material information. Buyers should rely on the part-number and application details rather than treating the material description as settled.
- Names Hydro-Gear model PK-BGAB-EY1X-XXXX
- References 116-2444 and 103-7262
- Also cross-references PJ-BGAB-EY1X-XXXX
- Specifies gas-powered lawn mower compatibility
- The listing gives conflicting material descriptions: aluminum and stainless steel.
Skip it if you need Exmark model and serial-number cutoffs; RONGPAS PK-BGAB-EY1X-XXXX provides specific Lazer series thresholds.
This suits an Exmark owner who can match the existing pump to the listed Hydro-Gear and OEM references. Individual mower models are not specified here, and the material descriptions conflict, so part-number verification is central.

View on Amazon#3 · Best Scag Fit
3. Hydro-Gear PG-1GCC Pump
Best for: Scag Wildcat and Tiger Cub fit.
Why it ranks #3: Genuine Hydro-Gear pump for Scag Wildcat and Tiger Cub mowers, replacing part 482644 and BDP-10A-419.
The Hydro-Gear PG-1GCC-DY1X-XXXX is identified as a genuine right-hand hydraulic pump for Scag Wildcat and Tiger Cub mowers, giving those owners a specific OEM replacement reference. Cross-references 482644, 13-695, and BDP-10A-419 further help compare the pump with an existing part.
The stated Scag Wildcat and Tiger Cub compatibility narrows the intended application, while the PG-1GCC-DY1X-XXXX and 482644 references provide concrete identification points. The listing also names 13-695 and BDP-10A-419 as cross-references. Alloy steel and aluminum are listed materials, with 1.5-inch inlet and outlet connection sizes specified; those connection details can inform service planning. Match the exact pump reference and mower application before installation, since the listing does not enumerate individual Scag models.
- Identified as a genuine Hydro-Gear part
- Names Scag Wildcat and Tiger Cub compatibility
- Provides 482644, 13-695, and BDP-10A-419 references
- Lists 1.5-inch inlet and outlet connections
- The listing does not specify individual Wildcat or Tiger Cub model years.
Skip it if you need Exmark Lazer AS or Toro Z500 fitment; Leyuncot PK-BGAB-EY1X-XXXX lists those applications and deck details.
This is for Scag Wildcat or Tiger Cub owners matching the right-hand pump and listed cross-references. Individual model years are not stated, so confirm the existing pump designation and application before beginning installation.

4. Hydro-Gear PG-1GAB Pump
- Weight: 4.69 kg
Best for: OEM part-number match.
Why it ranks #4: A genuine Hydro-Gear OEM part, but the supplied listing gives no mower models or replacement part numbers to confirm application.
The Hydro-Gear PG-1GAB-DY1X-XXXX is identified as a genuine original equipment manufacturer pump, giving buyers a specific OEM part number to compare against the component they are replacing. Its listed diaphragm style and silver finish further identify the part, while the 4.69 kg weight is useful to account for during handling.
This listing names the PG-1GAB-DY1X-XXXX model and identifies Hydro-Gear as both brand and manufacturer, which gives a buyer concrete identifiers for checking a replacement against an existing pump. The diaphragm style is also specified, helping distinguish it from other pump types. At 4.69 kg, it is a substantial component to handle during service. No mower models or cross-reference numbers are supplied, so application matching depends on the buyer's existing part identification.
- Genuine OEM part is specified
- Hydro-Gear brand and manufacturer are identified
- PG-1GAB-DY1X-XXXX model number is listed
- Diaphragm style and 4.69 kg weight are stated
- The supplied listing details do not identify compatible mower models.
Skip it if you need a listed mower application; Hydro-Gear PG-1GNP-DY1X-XXXX names Toro and Exmark applications.
This suits a buyer matching a mower's existing pump by the exact Hydro-Gear PG-1GAB-DY1X-XXXX designation and diaphragm style. The listing gives no mower applications, so model-specific shoppers need a part-number match before choosing it.

View on Amazon#5 · Best Toro Match
5. Leyuncot PK-BGAB Pump
- Weight: 9.92 lb
Best for: Toro and Exmark replacement.
Why it ranks #5: Lists Toro 103-7262 and 116-2444 compatibility for Z Master Z500 mowers from 2004 onward with 60- and 72-inch decks.
Compatibility with Toro Z Master Z500 mowers using 60- or 72-inch decks from 2004 onward gives the Leyuncot PK-BGAB-EY1X-XXXX a defined replacement target. The listed cross-references, including 103-7262 and 116-2444, also help owners compare the pump with their original part before beginning a repair.
The stated Toro Z500 fitment is limited to 2004-and-later machines with 60- or 72-inch decks, while Exmark Lazer Z AC/AS/LC models are also named. That specificity helps narrow the application check before disassembly. The listing cross-references PK-BGAB-EY1X-XXXX, PJ-BGAB-EY1X-XXXX, 103-7262, and 116-2444, giving several identifiers to compare. At 9.92 pounds, it is a substantial component to handle during installation; the listing advises matching model and part number.
- Lists Toro Z Master Z500 fitment for 2004-and-later models
- Specifies 60- and 72-inch deck applications
- Names Exmark Lazer Z AC, AS, and LC models
- Provides four replacement part-number references
- Toro fitment is specified for 60- and 72-inch decks, not other deck sizes.
Skip it if you have an Exmark Lazer AS with serial number 720,000 or higher; RONGPAS lists that threshold explicitly.
This is for Toro Z500 owners with the stated deck sizes and years, plus owners of the listed Exmark Lazer Z variants. Check the mower model and replacement number against the listed applications before ordering.

6. Beenhuco 103-7262 Pump
- Weight: 9.44 lb
Best for: Toro Z500 and Exmark fitment.
Why it ranks #6: Names Exmark Lazer Z AC, AS, and LC models and Toro Z500 mowers with 60- or 72-inch decks as compatible applications.
The Beenhuco pump lists Toro Z Master Z500 applications from 2004 onward with 60- or 72-inch decks, giving those owners a tightly specified fitment target. Its references to 103-7262, 116-2444, PK-BGAB-EY1X-XXXX, and PJ-BGAB-EY1X-XXXX provide several ways to compare the replacement part.
Along with the Toro Z500 years and deck sizes, the listing names Exmark Lazer AS and Lazer Z AC/AS/LC models. That application detail can help owners narrow the replacement before opening the mower. Four reference numbers—103-7262, 116-2444, PK-BGAB-EY1X-XXXX, and PJ-BGAB-EY1X-XXXX—make it easier to cross-check parts records or the old pump. The product dimensions are listed as 4.8 x 4.3 x 3.5 inches and weight as 9.44 pounds, useful details for handling and service planning.
- Lists Toro Z500 models from 2004 onward
- Specifies 60- and 72-inch deck fitment
- Names Exmark Lazer AS and Lazer Z AC/AS/LC
- Provides four reference part numbers
- Toro compatibility is specified only for the listed 60- and 72-inch decks.
Skip it if you need Exmark Lazer AS serial-number thresholds; RONGPAS PK-BGAB-EY1X-XXXX lists those application cutoffs.
This suits Toro Z500 owners with the specified years and deck sizes, along with owners of the named Exmark models. The fitment is application-specific, so verify the mower and reference number before scheduling the repair.

7. RONGPAS PK-BGAB Pump
Best for: Serial-specific Exmark replacement.
Why it ranks #7: Lists replacement numbers 103-7262 and 116-2444 and gives Exmark serial-number thresholds plus Toro Z500 deck applications.
RONGPAS specifies Exmark serial-number thresholds for Lazer AS and Lazer Z AC, AS, and LC models, making its fitment detail unusually targeted. The PK-BGAB-EY1X-XXXX reference also cross-links PJ-BGAB-EY1X-XXXX and Toro/Exmark numbers 103-7262 and 116-2444.
The listed Exmark thresholds are Lazer AS serial number 720,000 and up, and Lazer Z AC, AS, and LC serial number 510,000 and up. Toro Z500 Z Master models from 2004 onward with 60- or 72-inch decks are also named. These details help an owner verify application before ordering or taking the mower apart. The cross-references to PK-BGAB-EY1X-XXXX, PJ-BGAB-EY1X-XXXX, 103-7262, and 116-2444 provide additional comparison points; stainless steel is the listed material.
- Lists Exmark Lazer AS serial threshold of 720,000 and up
- Specifies 510,000-and-up thresholds for three Lazer Z models
- Names Toro Z500 models from 2004 onward
- References four pump and OEM part numbers
- The stated Exmark fitment depends on meeting the listed serial-number thresholds.
Skip it if you need a pump listing that names Exmark Lazer Z HP and CT; Hydro-Gear PG-1GNP-DY1X-XXXX identifies those models.
This is for owners whose Exmark serial numbers meet the listed thresholds or whose Toro Z500 matches the specified year and deck details. Check those application limits and the cross-reference numbers before starting replacement work.

8. Hydro-Gear PE-1KQQ Pump
Best for: Genuine Wright Stander OEM pump.
Why it ranks #8: Genuine OEM pump identified for Wright Stander applications, but the listing advises matching the Hydro-Gear number stamped on the pump.
This genuine OEM Hydro-Gear pump is identified for Wright Stander applications and PC Series references 31490026 and 31490004, giving owners a focused replacement target. The product description names PE-1KQQ-DN1X-XXXX and says it replaces OEM 31490026, while its service guidance emphasizes contamination control.
The PE-1KQQ-DN1X-XXXX designation and 31490026 replacement reference give buyers concrete identifiers to compare with the pump being removed. The listing also highlights an important maintenance sequence: replace the wheel motor and lines, flush the tanks, and install a new oil filter when replacing a hydro pump. Following that guidance addresses contamination risks identified by the manufacturer. This is a targeted Wright Stander/PC Series part, not a broadly specified mower pump, so application and stamped pump number matter.
- Identified as a genuine Hydro-Gear OEM pump
- Names Wright Stander and PC Series applications
- Lists PE-1KQQ-DN1X-XXXX and 31490026
- Provides contamination-control service guidance
- Replacement guidance calls for wheel-motor, line, tank, and filter service alongside the pump.
Skip it if you need a pump listing broad Toro and Exmark model applications; Hydro-Gear PG-1GNP-DY1X-XXXX supplies those references.
This suits Wright Stander owners matching the PE-1KQQ-DN1X-XXXX or 31490026 reference and prepared for the listed contamination-control steps. The PC Series designation and stamped pump number are key application checks.

9. sixcow 72274 Charge Pump Kit
- Weight: 1.01 lb
Best for: 72274 charge-pump replacement.
Why it ranks #9: Targets Hydro-Gear ZT2800, ZT3100, ZT3400, and G700 transmissions and replaces listed 72274 and 71411 references.
The sixcow kit cross-references Hydro-Gear 72274 and 71411 alongside Scag HG71411, HG72274, and PXHG72274, giving owners multiple identifiers for a charge-pump replacement. It lists ZT2800, ZT3100, ZT3400, and G700 series transmissions, with numerous mower applications also named.
Compatibility with ZT2800, ZT3100, ZT3400, and G700 series transmissions makes the kit relevant to owners checking those Hydro-Gear systems. The cross-reference list includes Hydro-Gear 72274 and 71411 plus three Scag numbers, helping compare the replacement with existing parts documentation. A stated 4.5 x 3 x 1.15-inch size and 1.01-pound weight give practical handling information for service planning. The product is a charge pump kit; the listing does not describe a bundled seal kit.
- Lists ZT2800, ZT3100, ZT3400, and G700 transmissions
- References Hydro-Gear 72274 and 71411
- Includes three Scag replacement-number references
- Lists dimensions and a 1.01-pound weight
- The listing does not include a separate transaxle seal kit.
Skip it if you want a 72274 charge pump bundled with transaxle seals; Bzcovac 72274 and 72994 combines both kits.
This suits a buyer replacing a 72274- or 71411-referenced charge pump on a listed transmission or mower application. The stated package is the charge-pump kit, so seal work calls for separately sourced components.

10. Bzcovac 72274 Repair Kit
- Weight: 5.9 oz
Best for: Charge pump and seal service kit.
Why it ranks #10: Combines a 72274 charge-pump kit with a 72994 seal kit for ZT-2800, ZT-3100, ZT-3200, ZT-3400, and G700 transaxles.
Including both the 72274 hydraulic transmission charge pump kit and 72994 transaxle seal kit is the Bzcovac bundle's defining feature. The combination targets maintenance or repair work on listed Hydro-Gear transaxles, letting a buyer source the charge-pump and seal components together for a service job.
The 72274 charge pump kit is paired with a 72994 seal kit, so the package addresses both charge-pump replacement and seal service rather than supplying only one of those listed components. Compatibility names Hydro-Gear ZT-2800, ZT-3100, ZT-3200, and ZT-3400, as well as G700 series transaxles and ZH, ZJ, ZK, ZL, and ZM models. That range helps owners of those systems plan a repair around a single kit. Confirm the transaxle designation before service.
- Includes 72274 charge pump kit
- Includes 72994 transaxle seal kit
- Lists ZT-2800, ZT-3100, ZT-3200, and ZT-3400
- Also names G700 and ZH, ZJ, ZK, ZL, and ZM systems
- This is a charge-pump and seal kit, not a complete transaxle.
Skip it if you only need a 72274 charge pump replacement; sixcow 72274-US lists the charge-pump kit without a seal-kit bundle.
This package suits owners servicing a listed Hydro-Gear transaxle who want the charge pump and seal kit together. Its scope is the named 72274 and 72994 components, so it is not a complete transmission replacement.

View on AmazonWhy pump contamination can cause repeat failure
Contamination can damage a replacement pump, so the pump itself may not be the only part to address during a repair. The Hydro-Gear Wright Stander listing specifically advises replacing the wheel motor and lines, flushing the tanks, and installing a new oil filter when replacing a hydro pump; it warns that skipping this work could cause pump failure from contamination. That advice is especially relevant when the old unit failed internally or the hydraulic system contains debris.
A new pump may restore operation temporarily, but the listing indicates that contaminated fluid or connected components can put the replacement at risk. Check the mower’s service guidance for the correct flushing and fluid procedure, since these product listings do not provide fluid type, capacity, or step-by-step installation instructions.
Do not treat a charge-pump kit or seal kit as a substitute for that system-level diagnosis.
Part-number overlap does not guarantee mower fit
Matching one replacement number is not enough unless the mower model and configuration also agree. Several listings share 103-7262 and 116-2444, but their fit notes add important limits: the Leyuncot listing specifies Toro Z Master Z500 models from 2004 onward with 60- or 72-inch decks, while the RONGPAS listing gives Exmark serial-number thresholds for particular Lazer models. The Hydro-Gear PK-BGAB listing names Exmark replacement numbers but provides a different set of fit details.
This variation is a reason to check the mower identification label, pump’s stamped number, serial range, deck configuration, and connector or mounting details against the seller’s fitment information before ordering. The supplied listings do not establish that pumps sharing a reference number are interchangeable across every mower or production run.
When fitment remains uncertain, verify the exact OEM reference with the mower or transmission documentation.
How to Choose a Mower Hydraulic Pump
Match the replacement part number
Start with the part number required by your mower or stamped on the existing pump, then compare every listed replacement reference. The products cover distinct families: PG-1GNP-DY1X-XXXX replaces 103-1942 and BDP-10A-414; PK-BGAB-EY1X-XXXX references 103-7262 and 116-2444; and PG-1GCC-DY1X-XXXX references 482644 and BDP-10A-These numbers are not interchangeable just because all products are hydraulic pumps for mowers.
Buyers with a readable original part number should prioritize an exact reference match. If the pump is missing or its marking is unclear, identify the mower and transmission model first and verify the application with the product listing or parts documentation before purchasing.
Check mower and deck compatibility
Use the model, serial range, and deck details in a listing to narrow the choices, rather than relying on brand alone. The Leyuncot replacement specifies Toro Z Master Z500 models from 2004 onward with 60- and 72-inch decks; the RONGPAS listing specifies Exmark Lazer serial-number thresholds and Toro Z500 applications. The Hydro-Gear PG-1GNP listing names Toro and Exmark models such as Lazer Z HP and Lazer Z CT.
Buyers whose mower matches a detailed application note have stronger fitment evidence than buyers considering a listing that gives no mower models, such as the PG-1GAB item. Confirm all stated limits before ordering, especially when the mower has a different deck size or production range.
Choose a complete pump or a repair kit
Decide whether you need a complete replacement pump or a component intended for a transaxle repair. The product set includes mower-specific replacement pumps, a 72274 charge-pump kit for ZT2800, ZT3100, ZT3400, and G700 transmissions, and a Bzcovac kit that combines a charge pump with a 72994 seal kit for ZT-2800 through ZT-3400 and G700 systems. The sixcow kit is the narrower component listing; the Bzcovac option includes seals as well.
Buyers diagnosing a charge-pump or leak-related transaxle repair may prefer a kit, while owners replacing a complete drive pump should select a pump listing that matches the original unit. Verify the transmission family and required repair parts before treating either kit as a complete pump replacement.
Which Hydraulic Pump Should I Choose?
Choose the Hydro-Gear PG-1GNP Pump if your mower calls for 103-1942 or BDP-10A-414; its listing names Toro and Exmark models, including Lazer Z HP and Lazer Z CT. For an Exmark application requiring 116-2444 or 103-7262, consider the Hydro-Gear PK-BGAB Pump, then confirm the exact mower fit. Toro Z500 owners should compare their year and deck against the Leyuncot PK-BGAB Pump listing.
For Scag Wildcat or Tiger Cub models requiring 482644 or BDP-10A-419, the Hydro-Gear PG-1GCC Pump is the targeted match. Choose the sixcow 72274 Charge Pump Kit or Bzcovac 72274 Repair Kit only when repairing a compatible Hydro-Gear transaxle, not as a general complete-pump replacement.
If your part number or fitment is uncertain, verify it before ordering.

Frequently Asked Questions
How can I verify that a replacement hydraulic pump fits my mower?
Match the mower’s required OEM part number to the replacement listing, then check the listed mower make and model. Confirm the exact application using your mower’s identification information or parts documentation before ordering. Similar-looking pumps or shared brand names alone do not establish compatibility.
Should I replace the wheel motor, lines, oil, and filter when changing a pump?
Not automatically; inspect the system and follow the mower’s service guidance. Replace components that are damaged, contaminated, or otherwise called for during diagnosis, and use the specified oil and filter procedures. If the cause of pump failure is unclear, have the system assessed before installing another pump.
What symptoms suggest a charge-pump or seal-kit repair instead of a complete pump replacement?
Visible oil leakage can make a seal-related repair worth investigating, while a charge-pump kit is intended for compatible transaxle service rather than general pump replacement. Symptoms alone do not confirm the fault. Check the transaxle model, identify the leak or failure, and consult service information before choosing a kit.
What should I do if my mower’s part number is missing or unreadable?
Use the mower’s model and serial identification, then consult its parts documentation or a qualified parts specialist to establish the correct pump number. Compare that number with the listing’s stated applications before buying. Do not select a pump solely because its description mentions the same mower brand.
Can a charge-pump kit replace a complete hydraulic pump?
No; a charge-pump or seal-service kit is a repair component for a compatible transaxle, not a general complete-pump replacement. Confirm the transaxle family and kit application first. If the mower requires a complete pump, use a pump listing that matches its required OEM number and application.
Final Words
Start with the mower’s required OEM number, then verify the listed make and model before choosing a complete pump. The PG-1GNP-DY1X-XXXX is the best overall match here when the mower calls for 103-1942 or BDP-10A-414; other listed numbers point to different application-specific options. Treat charge-pump and seal kits as targeted transaxle repairs, not substitutes for a complete pump.
If fitment remains uncertain, confirm it before ordering.
