Maintenance
Basic Maintenance Schedule
See the original equipment manufacturer’s operating
manual for a complete list of maintenance requirements.
Failure to comply with the procedures as described in the
engine operator’s manual will nullify the warranty,
decrease performance, and cause equipment damage or
premature equipment failure. Maintenance records may
be required to complete a warranty request.
IMPORTANT NOTE: Refer to the engine operator’s
manual for additional maintenance information.
* Change the oil and oil filter after the first 100 hours, then every 250 hours. If John Deere Plus 50 II engine oil is
used, the interval can be increased to every 500 hours.
** Increased inspections required under dusty or damp conditions. See Trailer Wheel Bearings for more information.
