OPERATION AND MAINTENANCE

Variable Ratio Adjustment

The leveler is equipped with a variable ratio adjustment.

This is located at the rear of the hitch and at the center of

the wheel lift where the leveler tube attaches. Connect

the leveler tube to the top hole in the center lift and the

bottom hole in the tongue for normal operation. This will

cause the rear of the machine to raise higher than the

front increasing transport height. The lower hole on the

center lift provides an increased leveler ratio, which will

cause the Coulter Chisel to become more level in

transport. The lower hole should be used when a rear

tow hitch is needed to reduce the height of the rear tow

hitch during transport.

The adjustments can be set as follows:

• Top hole in center lift, top hole in tongue - this will

raise the rear of the machine the highest.

• Top hole in center lift, bottom hole in tongue - normal

operation.

• Bottom hole in center lift, top hole in tongue - normal

operation with a tow hitch

• Bottom hole in center lift, bottom hole in tongue - to

lower rear tow hitch if needed.

1. To change the variable ratio adjustment, lower the

implement to the ground and relieve the load on the

lift system.

2. Extend or retract the radius rod, until the load is

removed from the leveler tower.

3. Remove the 1-1/4-7 x 9-1/2 hex head cap screw,

slotted lock washer, and hex nut through the leveler

tower and hitch (See Figure 4-10.)

4. Reinstall the 1-1/4-7 x 9-1/2 hex head cap screw,

slotted lock washer, hex nut, and leveler tower in the

desired position. The radius rod will require some

adjustment to connect to the new position.

5. To adjust the leveler tube at the center lift, remove

the hitch pin, 1/2 x 2-1/4 slotted spring pin, and 1-8

hex lock nut.

6. Reinstall the hitch pin, 1/2 x 2-1/4 slotted spring pin,

1-8 hex lock nut in the leveler tube at the center lift in

the desired position.
