Part of the John Deere Repair Manuals.
This is the complete John Deere factory technical manual for the F911, F915, F925, F932 and F935 front mowers. Across 1,091 pages it covers every major system on the machine: engine removal and rebuild for each model's engine family, hydrostatic transmission and axle service, PTO clutch and blade drive repair, hydraulic lift cylinder and control valve overhaul, steering and brake service with hydraulic schematics, and the full electrical system with wiring diagrams. Model-specific operations, tests and adjustments chapters are provided for F911, F915/F925/F935 and F932 separately so you are working from the correct procedure for your machine. It is the same information a John Deere dealer technician uses, with the torque values and test pressures called out for each assembly.

John Deere F911, F915, F925, F932, F935 Common Problems This Manual Covers
Deck fails to lift or lowers unexpectedly despite hydraulic pump running
Check the hydraulic control valve spool for sticking due to contaminated oil and inspect the lift cylinder seals for wear. The Hydraulic System section covers removing and pressure-testing the control valve, rebuilding the hydraulic lift cylinders and inspecting the weight transfer valve so you can confirm where the pressure loss is occurring before replacing the pump.
Manual Section: Hydraulic SystemPTO clutch disengages blade drive without operator input or fails to engage
Inspect the PTO clutch wiring harness for chafed insulation and test the clutch coil resistance. The Electrical System section covers the PTO clutch circuit and the ignition and charging system tests for each model, letting you isolate a failed clutch coil, a wiring fault or a relay issue without swapping parts blindly.
Manual Section: Electrical SystemEngine stalls under mowing load with black exhaust and rough idle
Service the fuel filter and inspect the air filter for restriction. The Fuel and Air section covers the fuel system for F911/F932 and F915/F925/F935 separately, with the air system procedures and test specifications, so you can verify adequate fuel supply and intake flow before suspecting the carburetor or injection system.
Manual Section: Fuel and AirExcessive vibration and uneven cutting height even after blade replacement
Inspect the blade spindle bearings for wear and check the deck housing for a bent mounting point. The Miscellaneous section covers mower deck repair and ROLL-GARD service so you can verify spindle bearing condition and deck levelness, and the General Information section gives the correct deck-leveling adjustment specs for each model.
Manual Section: MiscellaneousFrequently Asked Questions
What engines do the John Deere F911, F915, F925, F932 and F935 use?
The F911 and F925/F935 share a 16.4 kW (22 Hp) engine, the F915 runs a smaller 11.9 kW (16 Hp) unit, and the F932 uses a larger diesel producing 20.9 kW (28 Hp). The manual covers repair procedures for each engine family separately so the correct teardown sequence and torque specs apply to your model.
Why won't the mower deck lift even after checking the hydraulic pump?
The most common cause is worn lift cylinder seals or a stuck directional control valve spool from hydraulic contamination. The Hydraulic System section covers removing and rebuilding the hydraulic control valve, lift cylinders and weight transfer valve so you can isolate whether the fault is a seal failure, a sticking spool or a restricted oil circuit.
What causes the PTO blade drive to stop without any warning?
A sheared PTO shaft coupling or failed blade drive belt tensioner is the typical culprit. The Electrical System section covers the PTO clutch and its wiring, and the Miscellaneous section addresses mower deck drive components, so you can confirm whether the stoppage is a mechanical drive failure or an electrical clutch fault before ordering parts.
Why does the engine stall under mower load with black exhaust smoke?
Black smoke under load usually means fuel starvation from a clogged filter combined with restricted air intake. The Fuel and Air section covers the fuel system and air system for each model variant with the correct service intervals, so you can rule out fuel delivery and intake issues before suspecting the injection system.
Does this manual include wiring diagrams and hydraulic schematics?
Yes. The Electrical System section includes model-specific wiring schematics for F911, F915/F925/F935 and F932 separately. The Steering and Brakes section includes the hydraulic system schematic diagram. Having both lets you trace intermittent faults in the charging circuit or hydraulic control circuit without guessing at connector locations.
