The tractor hydraulic oil also serves as the tractor transmission fluid. During cold weather operation, the hydraulic
oil viscosity increases. This increase in oil viscosity restricts the oil's ability to flow and lubricate in the transmission
and hydraulic circuits. The cold oil can result in abnormal noises and slower operation times due to the increased oil
viscosity.
NOTE:
A warm up time at
50%
rated engine speed is recommended to assure proper vehicle functionality, transmis-
sion lubrication and operation.
NOTE:
Do not operate the tractor under full load condition until the hydraulic oil is sufficiently warmed up.
