Hydraulic Single Point Depth Stop Adjustment:

The hydraulic depth stop will ensure a consistent depth

every time the machine is lowered.

1) Prior to setting the single point depth stop, ensure

that the machine is completely level front to back and

side to side.

2) Lower the machine to the desired working depth and

pull forward. Once satisfied with the working depth,

adjust the depth stop handle to make contact with the

depth stop valve.

Note: If a change of depth is desired,

1 full turn on the depth stop handle either in or out will

change the depth of the machine approximately 1/4" up

or down.

Gauge Wheel Adjustment:

Note: The gauge wheels are desired to run 1/2" above

the ground when operating in the field.

1) With the machine lowered into the desired operating

position, remove the wire retaining pin and adjust the

gauge wheel crank either up or down until the gauge

wheels are 1/2" above the ground.

wheels are designed to correspond to the single point

depth stop. If the depth stop is increased one full revolu-

tion then the gauge wheels need to be increased one

full revolution, ect.

Spike Drag Adjustment:

Spike drags come factory set with 5 chain links hanging

from the bottom drag arm slot. The cleaner the ground,

the shorter the pull chains may be pulled up.

Ensure that the spike drag is never pulling off of the

hang chains. If so, shorten the chains.
