Adjusting the Front Wheel
Toe-in
Service Interval:
Every 100 hours/Yearly (whichever comes
first)—Check the front wheel toe-in.
Important:
You need Toro Tool No. 6010 from your
Toro Distributor to perform this procedure.
The toe-in should be 0 +/– 3 mm (0 +/– 1/8 inch).
•
Check the tire pressure to ensure that the front tires are
inflated to 165 to 207 kPa (24 to 30 psi).
•
Either, add weight to the driver's seat equal to the average
operator who will run the machine, or have an operator
sit on the seat. The weight or operator must remain on
the seat for the duration of the procedure.
•
On a level surface, roll the machine straight back 2 to 3
m (6 to 10 ft) and then straight forward to the original
starting position. This allows the suspension to settle into
the operating position.
•
Measure the toe-in with the wheels facing straight ahead.
Adjust the riding height to the desired position by performing
the following procedure:
1.
Using Toro Tool No. 6010, rotate the collar on the
shock absorber to change the length of the spring
(
