Mow/Lift Switch Replacement and Adjustment (Fig. 17)

IMPORTANT: Spool travel for 1, 2 and 3 spools must be correct before Mow/Lift switch can be adjusted. (See Rear Camshaft Adjustment in the Adjustments section of Chapter 4 - Hydraulic System.)

1.Pull connector off switch terminals from end of mow/lift switch installed in the valve bank bonnet.

2.Loosen jam nut and unscrew switch from valve bank bonnet.

3.While holding lift pedal in fully depressed position (valve bank spools fully IN) partially screw new switch into bonnet.

4.Connect continuity tester on ohm meter across switch terminals and turn switch in until continuity occurs. Then rotate switch in 1/2 turn (180) and secure jam nut to 75 in.-lb. (8.5 Nm) against the bonnet.

IMPORTANT: Switch threads will be damaged if the jam nut is over-tightened.

5.Connect continuity tester or ohm meter to switch terminals and depress the mow pedal. There should not be continuity. If there is continuity, repeat step 3. Pro- ceed to step 6 if there is no continuity.

6.Depress the lift pedal and release it (neutral position). The switch circuit should have continuity.

7.Fill terminal end of switch and wiring harness cover with skin-over grease and push connectors onto switch terminals.

Wiring Harness Service

Prevent corrosion of the wiring terminals by applying skin-over grease to the inside of all harness connectors whenever the harness is disconnected.

Always disconnect the battery cables, negative (–) ca- ble first, to prevent possible wiring damage from short- outs whenever working with the electrical system.
