Dipstick not seated or broken. Replace defective part.
Engine breather defective. Replace.
Stop engine immediately. Check all pulleys, blade adapters, keys and bolts for tightness and damage. Tighten or replace any damaged parts.
Stop engine immediately. Replace damaged blade. Only use original equipment blades.
Throttle must be set between 3/4 and full throttle.
Use lower transmission speed. The slower your ground speed, the better the quality of cut. Sharpen or replace blades (uncut strip problem only).
No output torque (power) in eitherdirection, cold start.
1.Recheck relief valve position, control linkage, input drive.2. Oil level in reservoir low.
3.Broken control shaft dowel pin. Transmission must be repaired or replaced.
Loss of output torque, continuous
load.
1.Operating at conditions approaching hydraulic stall. The transmission fluid has exceeded 1800 F.
2.Internal leakage due to wear. Transmission should be repaired or replaced.
3.Water in transmission fluid. Purge system of all fluid and replace with new transmisison fluid. Replacement of the transmission is generally not necessary.
No output torque in one direction.1. One of the directional valves is stuck. Transmission should be repaired or
replaced.
2. Low oil level.
Lawn tractor cannot be pushed with engine off.
No neutral.
Oil leakage at the control shaft seal.
1.Relief valve control not set.
2.Relief valve travel not adjusted.3.
Motor piston or rotor seized. Transmission must be repaired or replaced.
Recheck linkage. Loose linkage creates an adjustment problem.
Note: The hydraulic neutral band is very narrow. Deflection in the linkage may make it difficult to obtain neutral from both directions. It is recommended that neutral should be positive from forward drive.
1.Spillage when fluid has been added to the reservoir.
2.Spillage at the vent in the reservoir at operating temperatures due to cold level being too high or water in the fluid. Reduce fluid level or replace fluid in the event there is water in it (milky color).3.
Loose oil reservoir or cover.4. Loose vent bolt.5.
Damaged control shaft seal. Transmission should be repaired.
Noisy operation.
Output shaft rotates in the opposite direction.
1.Operating at part throttle. Hydrostatic transmission is designed to operate with the engine running at full throttle.2.
Water in transmission fluid. Replace transmission fluid.
3.Air in transmission fluid. Bleed air from vent.
The transmission body is 1800 out of position. Transmission has to be removed and reassembled correctly.
