Gauge Wheels
The gauge wheels keep the machine steady and maintain the working depth in the ground. The wheels
only have a sensing and supporting function. They are not designed as load bearing transport wheels.
The gauge wheel can be set, but not until after the depth setting has been completed.
When starting work the gauge wheel should be in its highest position.
Lower the machine in to the soil at the working depth and then turn the turnbuckle of the gauge wheel
to lower the tire to the ground.
The gauge wheel is lifted at the headland when the machine is taken out of the ground.
Setting Gauge Wheels:
1. Before setting the depth of the implement, raise the gauge wheel to its highest position by
turning the turnbuckle.
2. Set the desired machine depth. (See procedure in previous section).
3. Lower the implement to the predetermined set depth in to the ground.
4. Turn the turnbuckle to lower the gauge wheel to the ground.
NOTE: The tires should only support the machine on the ground in case of obstructions and following
the contour of the field. The frame must always rest on the stop screws. The wheels should not lift
up the side wings when in operation.
