disconnected from the valve.
6. Attach a 5/16 in. internal diameter hose to the valve to
help drain the fuel into the container.
7. Open the valve and allow gasoline to drain into a gas

Servicing the Front Wheel
Toe-In
Maintaining correct front wheel toe-in is important for
safety, Smart Turn steering operation, and ease of use. If
uneven tire wear, lawn scuffing, or hard steering develop,
you may need to adjust the toe-in of the front wheels.
Check the toe-in after every 100 operating hours or once a
year, whichever occurs first.
Maintain the following specification: 1/8–1/4 inch
(3.5–6.5 mm) toe-in on the front wheels.
Measuring Toe-In
1. Disengage the PTO, set the parking brake, lower the
attachment lift, stop the engine, and remove the
ignition key.
2. Turn the wheels straight ahead.
3. Push the front of the tires out to remove normal
looseness in the linkage.
4. Measure the distance between both of the front tires at
spindle level (at the front and rear of the wheels) (Fig.
43).
