Adjusting Front Wheel Toe-In; Servicing The Fuel System; Spark Plugs - Toro 07253 Operator's Manual

Adjusting Front Wheel Toe-In

Check the front wheel toe-in after every 100 operating
hours, or annually, whichever occurs first.
1. Ensure that the distance from the bottom of the tongue
to the ground is 9 to 9-3/4 in. (22.9 to 24.8 cm) when
the tires are inflated to 12 psi. (83 kPa). Adjust if
necessary; refer to Adjusting the Front Suspension,
page 30.
2. Measure the distance between both of the front tires at
axle height (at the front and rear of the wheels)
(Fig. 36). The front measurement must be equal to the
rear measurement 1/4 in. (6.4 mm).
Figure 36
3. If the measurement is greater than 1/4 in. (6.4 mm),
loosen the jam nuts at both ends of the tie rods
(Fig. 37).
4. Rotate both tie rods to move the front of the tire inward
or outward.
