4.3.3.SHIFTER ADJUSTMENT
The shift linkage is set at the factory and should not require further adjustment. The shifter is adjusted properly when the speed control lever can be placed at rear edge of the neutral detent and the tractor remains absolutely stationary. If motion is detected, neutral adjustment will be required. DO NOT operate a machine that creeps when shifted to neutral.
1.Stop engine. Remove key.
2.Move speed control lever to rear edge of neutral detent and hold firmly.
3.Locate neutral adjustment nut underneath the right rear of the tractor. See Figure 4.11.
