Cylinder Stops on Lift Assist
Cylinders
Refer to Figure 61
The lift assist lock stops are used to the hold the lift
assist cylinders at the desired height during planting.
To install:
1. Raise the hitched planter to the desired planting
height. Leave the tractor hitch and implement lift
circuits in neutral.
2. Remove the cylinder stop from the wire loops .
3. Install the cylinder stops on the rods of the lift assist
cylinders.
To remove:
1. Raise the hitched planter. Leave the tractor hitch

Gauge Wheel Functions
Refer to Figure 62
The gauge wheels serve three functions:
1. Regardless of meter drive type, the gauge wheels
each establish the heights of their respective
sections. A spring-loaded yoke assembly provides
some flexibility over rocks and uneven ground.
“ Adjusting Ground Drive ”.
2. On ground drive models, each gauge wheel
contributes drive power for its respective row unit
mechanisms (on 3-drive models these systems are
fully independent).
On hydraulic drive models, power for the row unit
mechanisms is supplied by hydraulic motors. One of
the gauge wheels is equipped with a sensor that
relays the speed of the planter to the planter monitor.
3. On ground drive models, the gauge wheels control
the planting rate at the meter.
On hydraulic drive models, one of the gauge wheels
relays planter speed information to the planter
monitor. The planter monitor controls the planting
rate at the meters.
