Note: Over a period of time, a deck motor can wear in-

ternally. A worn motor may by--pass oil to its case drain

causing the motor to be less efficient. Eventually,

enough oil loss will cause the deck motor to stall under

heavy cutting conditions. C ontinued operation with a

worn, inefficient motor can generate excessive heat,

cause damage to seals and other components in the hy-

draulic system, and affect quality of cut.

Note: One method to identify a possibly bad deck mo-

tor is to have another person observe the machine while

mowing in dense turf. A bad motor will run slower, pro-

duce fewer clippings, and could cause a different ap-

pearance in the turf.
