WARNING

If you do not understand how a specific control functions, or have not yet thoroughly read the FEATURES & CONTROLS section, do so now. Do NOT attempt to operate the tractor without first becoming familiar with the location and function of ALL controls.

STARTING THE ENGINE

1.While sitting in the operator’s seat, engage the parking brake and make sure the PTO switch is disengaged and the motion control handles are locked in the NEUTRAL position.

2.NOTE: A warm engine may not require choking. Set the engine throttle control to FAST throttle position. Then fully close the choke by pulling the knob OUT fully.

3.Insert the key into the ignition switch and turn it to

START.

4.After the engine starts, gradually open the choke (push knob down fully).

Warm up the engine by running it for at least a minute before engaging the PTO switch or driving the rider.

5.After warming the engine, ALWAYS operate the unit at FULL THROTTLE when mowing.

In the event of an emergency the engine can be stopped by simply turning the ignition switch to STOP. Use this method only in emergency situations. For normal engine shut down follow the procedure given in STOPPING THE RIDER.

STOPPING THE RIDER AND ENGINE

1.Returning the ground speed control levers to the middle position will stop tractor movement. Pivot the levers outward and lock them in NEUTRAL.

2.Disengage the PTO by pushing down on the PTO switch.

3.Engage the parking brake by pulling the handle up until it locks into position.

4.Move the throttle control to mid-throttle position and turn the ignition key to OFF. Remove the key.
