4165709 High-Torque PTO Clutch for Bobcat ZT6000 & ZT7000 | Warner 5228-30, 522830
Overview
This aftermarket HD Switch 4165709 electric PTO clutch is a high-torque replacement for select Bobcat commercial zero-turn and walk-behind mowers using the 4165709 non-EFI clutch path.
Confirmed application families include select Bobcat ZT6000, ZT7000, ZT6100, WB700, and legacy Bob-Cat / Bunton Predator Pro mower configurations. Fitment depends on the complete model number, serial number, engine configuration, wiring harness, and original clutch number.
HD Switch markets this upgraded clutch with a 260 ft-lb torque rating, larger C3 pulley bearing, solid-steel billet pulley, replaceable pulley-bearing design, and improved heat management. The corresponding OEM Warner 5228-30 clutch path is rated at 250 ft-lbs.
Important EFI warning: Bobcat parts documentation separates 4165709 for non-EFI models from 4165689 for EFI models. Do not order from the ZT6000, ZT6100, or ZT7000 series name alone.

Compatible Brands & Model Series
This clutch should be treated as a part-number, serial-number, and engine-configuration-specific replacement. Bobcat lists 4165709 across several mower generations, but individual machines within those families may use a different clutch.
Confirmed Non-EFI Bobcat ZT6000 Paths
- Bobcat ZT6000 9996010: Kawasaki FX801V, 25.5 hp, 52-inch side-discharge deck
- Bobcat ZT6000 9996011: Kawasaki FX801V, 25.5 hp, 61-inch side-discharge deck
- Bobcat ZT6000 9996012: Kawasaki FX850V carbureted engine, 27 hp, 61-inch side-discharge deck
Bobcat parts documentation identifies 4165709 as the 250 ft-lb clutch used on these non-EFI configurations.
Bobcat ZT7000 Applications
Bobcat documents 4165709 in the non-EFI ZT7000 electrical and engine-deck paths. Official compatibility listings include select:
- 9997001 and 9997001AU
- 9997002
- 9997003
- 9997004 and 9997004AU

- 9997006
- 9997010
- 9997011
- 9997012
- 9997013
ZT7000 configurations may use 61-inch or 72-inch decks and different Kawasaki engine packages. Confirm the serial-specific parts diagram rather than ordering from deck size or horsepower.
Additional Bobcat Compatibility Paths
Bobcat’s official parts system also associates 4165709 with select:
- Bobcat ZT6100 configurations
- Bobcat WB700 walk-behind mowers
- Bob-Cat and Bunton Predator Pro commercial mowers
- Bob-Cat ZT-series commercial mowers
- Legacy model-number paths beginning with 942
Officially listed legacy model-number paths include:
- 942512G, 942513G
- 942514G, 942514J, 942514K
- 942515G, 942515J, 942515K
- 942516G, 942516J, 942516K

- 942540K, 942541K
- 942545L, 942545M
Compatibility-list warning: The presence of a model number in Bobcat’s broad compatibility system does not override the serial-number-specific parts diagram. Parts can change within a model-number family.
EFI & Non-EFI Clutch Routing
Bobcat uses separate clutch paths for documented EFI and non-EFI mower configurations:
- Bobcat 4165709: 250 ft-lb clutch used on documented non-EFI configurations
- Bobcat 4165689: 225 ft-lb clutch used on documented EFI configurations
Documented EFI example:
- Bobcat ZT6100 9996013: Kawasaki FX850V EFI, 29.5 hp, 61-inch deck — uses 4165689 rather than 4165709 in the referenced parts documentation
Later ZT7000 parts manuals also show separate non-EFI and EFI lower wiring-harness diagrams. The non-EFI diagram identifies 4165709, while the EFI diagram identifies 4165689.
Do not substitute these two clutches based only on pulley size, torque rating, deck size, or physical appearance. Confirm the engine fuel system and serial-specific parts diagram.
Replaces OEM Part Numbers
- Bobcat: 4165709
- Bob-Cat: 4165709
- Bunton: 4165709
- Ryan: 4165709

Important Fitment Check
Do not order this PTO clutch by mower appearance or model-family name alone. Bobcat commercial mower families may use different clutches based on serial number, EFI or non-EFI engine configuration, wiring harness, deck system, crankshaft, and production revision.
Before ordering, confirm:
- The original clutch or Bobcat parts diagram identifies 4165709
- The original Warner number is 5228-30 when the Warner label is readable
- The mower uses the documented non-EFI clutch path
- The crankshaft bore measures 1-1/8 inch
- The pulley diameter is approximately 6.31 inches
- The rotation is CCW using the same viewing convention
- The pulley offset and belt grooves match the original clutch
- The electrical connector and clutch cable match the mower wiring
- The clutch works with the installed PTO control system
- The D-drive and anti-rotation setup match
- The clutch pin and clutch-stop bracket provide proper clearance
- The complete mower model and serial number have been checked
Bobcat recommends using the mower’s serial number when confirming replacement parts. Serial-number lookup is more reliable than the ZT6000, ZT6100, ZT7000, Predator Pro, or WB700 name alone.
Wiring, D-Drive & Clutch-Control Considerations
The factory Warner 5228-30 clutch path lists a 5218-251-001 cable accessory and 807-0078 D-drive. Bobcat mower parts diagrams may also use separate clutch wiring, clutch pins, clutch stops, and control components.
- 2720949: documented Bobcat clutch wire
- 4169106: documented tall clutch pin
- 4174466.46: documented clutch-stop weldment
- 4169459: documented soft-start clutch control on applicable configurations
These numbers are provided for identification and diagnostic purposes. They are not represented as included with the linked HD Switch clutch.
A failed clutch-control module, damaged wire, incorrect cable, poor ground, blown fuse, defective PTO switch, or charging-system problem can prevent engagement even when the clutch itself remains functional.
Common Symptoms of a Failing PTO Clutch
- Blades will not engage when the PTO switch is activated
- Clutch clicks but the mower deck does not begin turning
- Blades engage when cold but stop after the mower heats up
- Clutch slips during heavy or wet commercial cutting
- Deck belt squeals, smokes, or overheats during engagement
- Burning smell near the engine crankshaft or clutch
- Grinding, rumbling, or excessive pulley-bearing noise
- Intermittent engagement caused by a heat-damaged coil
- Visible heat damage around the coil housing or connector
- Excessive movement or roughness at the pulley bearing
Similar symptoms may be caused by a PTO switch, clutch controller, wiring harness, fuse, poor ground, low charging voltage, slipping belt, seized spindle, dragging idler, or damaged clutch stop. Diagnose the complete electrical and deck-drive systems before replacing the clutch.

FAQ
What does this HD Switch PTO clutch replace?
This clutch is marketed as a high-torque aftermarket replacement for Bobcat 4165709 and Warner 5228-30.
Is this a complete PTO clutch?
The eBay title and product photos represent a complete assembled PTO clutch. However, the item specifics classify it as a clutch rebuild kit. Confirm the current package contents directly with the eBay seller before purchasing.

The Warner 5228-30 reference path uses a 1-1/8-inch bore, 6.31-inch pulley, CCW rotation, 12 VDC coil, and 250 ft-lb torque rating. HD Switch markets its replacement at 260 ft-lbs.
Does Bobcat 4165709 fit the ZT6000?
Yes, 4165709 is documented on select non-EFI ZT6000 configurations, including models 9996010, 9996011, and 9996012. Confirm the serial-specific parts diagram before ordering.
Does it fit ZT6000 model 9996010?
Yes, 4165709 is documented for the non-EFI 9996010 path using the Kawasaki FX801V engine and 52-inch deck. Serial-number verification is still required.
Does it fit ZT6000 model 9996011?
Yes, 4165709 is documented for the non-EFI 9996011 path using the Kawasaki FX801V engine and 61-inch deck.

Yes, 4165709 is documented for the non-EFI 9996012 path using the carbureted Kawasaki FX850V engine and 61-inch deck.
Does it fit ZT6100 model 9996013?
No, the documented 9996013 Kawasaki FX850V EFI path uses Bobcat 4165689, not 4165709.
Does Bobcat 4165709 fit the ZT7000?
Yes, Bobcat documents 4165709 across select non-EFI ZT7000 applications. Confirm the complete model and serial number because EFI ZT7000 configurations may use 4165689.
Does it fit the Bobcat WB700?
Bobcat’s official compatibility system lists select WB700 walk-behind mower applications. Confirm the original clutch number and serial-specific parts lookup before ordering.
Does it fit older Bob-Cat Predator Pro mowers?
Bobcat’s official compatibility system lists several legacy 942-series, Predator Pro, Bunton, and Bob-Cat ZT paths. Use the complete model and serial number because those families span many production configurations.
Is Bobcat 4165709 the same as 4165689?
No. Bobcat documents them as separate clutch paths. The 4165709 is the documented 250 ft-lb non-EFI clutch, while 4165689 is the documented 225 ft-lb EFI clutch.
Is Warner 5228-30 the correct cross-reference?
Yes. Warner’s official product data identifies manufacturer part number 4165709 for clutch 5228-30.
Is Warner 5228-20 the same replacement?
Do not use 5228-20 as the primary match. Some aftermarket catalogs associate it with 4165709, but Warner’s official manufacturer-number listing identifies 5228-30. Match Bobcat 4165709 or Warner 5228-30.
Is the clutch cable included?
Do not assume it is included. The factory Warner 5228-30 package lists cable accessory 5218-251-001, but the linked HD Switch package may differ. Confirm the seller’s photos and description.
Is the D-drive included?
Do not assume it is included. Warner lists D-drive 807-0078 with the OEM 5228-30 clutch, but the HD Switch package contents may be different.
Why is the HD Switch clutch rated at 260 ft-lbs?
HD Switch markets this version as a high-torque upgrade with increased holding capacity, a larger bearing, and billet pulley. The OEM Warner 5228-30 path is rated at 250 ft-lbs.
Can I order this clutch by appearance?
No. Match Bobcat 4165709 first, then confirm the complete model and serial number, EFI status, bore, pulley diameter, rotation, connector, cable, D-drive, belt alignment, clutch pin, and clutch-stop arrangement.
Who handles shipping, returns, and warranty?
The linked eBay seller handles payment, shipping, returns, and any seller-provided warranty. Review the current eBay listing terms before purchasing.
