Operation

Starting the Engine

 1.  While sitting in the operator’s seat, engage the 

parking brake by pulling the parking brake lever 
back, make sure the PTO switch is disengaged 
(pressed down fully) 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 FULL 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).  Reduce to half throttle 
speed and allow to warm up.

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

 1.  Returning the ground speed control levers to the 

middle position will stop rider 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.

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.

Pushing the Rider By Hand

 1.  Disengage the PTO, engage the parking brake, 

turn the ignition OFF, and remove the key.

 2.  Open the hydraulic bypass valve. To open the 

bypass valves, turn the bypass valve, which 
is located on the side of the transmission, 
CLOCKWISE. See Figure 6 for valve location.

 3.  Disengage the parking brake.  The tractor can 

now be pushed by hand.

 4.  After moving the tractor, re-engage the 

transmissions (drive position) by turning the 
bypass valves COUNTER-CLOCKWISE.
