DANGER: Never use the machine without first assuring all protective devices are
properly installed. Never forget that due to their high blade tip speed, blades can
be thrown great distances and cause injury or death to bystanders.
CAUTION: For emergency reasons, learn how to stop the tractor and implement
quickly. On the aerator-overseeder, always disengage the PTO, lock parking
brake, stop engine and allow the blades to come to a complete stop before
dismounting the tractor.
3.15 - Test Run
After the first 200-300 feet it is important to stop, raise the machine and disengage the
PTO just as the blades are coming out of the ground. Lower the machine, turn off the
tractor engine and remove the key.
At this point make sure the aerator-overseeder is performing correctly. Check for loose
bolts or nuts, paying particular attention to the blade bolts.
3.16 - Working Depth
When using the aerating rotor which comes standard with the machine, normally a
depth of approximately ¾” is all that is desired. This is enough to loosen the soil without
tearing up existing grass. It is very important to check the depth prior to the corrugated
roller going over where the blades have cut into the ground.
With the optional tilling rotor the depth of cut is determined largely by the condition of
the ground. When working hard or previously unworked ground, set depth at no more
than 2”-3”. Greater depth may require a second pass. The maximum tilling depth is 7”.
NOTE: Excessive vibration or jumping of the machine is an indication that the
machine is working too deep for conditions, such as in hard, parched or
compacted soil and should be adjusted accordingly.
3.17 - Working Speed
Ground speed is determined by the soil condition, depth of cut, and tractor power.
Simple experimentation will soon determine the best speed for the desired results,
usually 1 to 2 mph.
When using the aerating rotor the blades need to make a continuous slice, if there is
some skipping you need to slow down the ground speed.
A slow ground speed with the tilling rotor will result in a finer soil, as a faster ground
speed will render the opposite. The rear shield, besides being a safety device, will help
