and stop the engine. Disengage the PTO and engage the
parking brake.
2. Raise the seat.
3. Jack up the front of the machine until the tires are off of
the shop floor. Support the machine with jack stands to
prevent it from falling accidentally.

machine and cause a serious injury.
• Use jack stand when supporting machine.
• Do not use hydraulic jacks.
