The front wheels should have 1/4 inch
(: 1/16-inch) toe-in (1/4-inch closer in front
than in the rear). To check the toe-in, place
chalk marks at point I'G" on each rim at hub
height, Illust. 45, and measure the distance be-
tween them. Move the tractor forward a dis-
tance equal to one-half revolution of the front
wheels. The chalk marks should now be at
point "F". The measurements between points
IIFII should be 1/4-inch (: 1/16-inch) greater
than at IIG".
Raise the front end of the tractor.

clamps "A".
