Troubleshooting

Problem
Springs are breaking or not pulling back the
head to normal position.
Holes are elongated or picking.
Tines are hitting the ground with an erratic
pattern.
PTO clutch slips excessively.
Turf is pulling up with coring tines.
The soil is too hard for full penetration.
Coring tines are breaking.
The tines do not stay in the head.
Tines pull the soil up when the machine is
raised.
The machine does not turn.
The tractor has difficulty lifting the aerator.
The hydraulic top link cylinder is spongy. (It
"gives" and moves in and out a short span
when force is applied.
The machine is noisy or knocking.
The hydraulic top link cylinder can not be fully
retracted (PTO shaft jams).
The tractor is difficult to steer when in
transport.
The camber bracket is damaged.
Slow the PTO speed of the tractor. The longer and heavier the tines, the greater the
centrifugal force on the head. Check for crossed or broken spring wires.
Adjust the angle of the tine or change the tractor ground speed. Make sure that the
aerator can be lowered at least 5 cm (2 inches) below flat ground level to allow
for undulation.
• Check for crossed or broken spring wires.
• Slow the PTO speed of the tractor.
Adjust the tines to a shallower depth. Review the clutch adjustment procedure.
Replace PTO clutches.
Shallow-rooted turf may require solid tines the first time.
Aerate at a depth that the machine can achieve, water overnight, and then increase
the depth. Repeat if necessary until soil can be aerated at the desired depth.
You are trying to get too much depth for the soil condition. See above and aerate to
a shallower depth.
Tighten the tine holder bolts; do not use jam nuts or an impact wrench. If the bolt
does not hold the tine, replace it.
Raise the machine part of the way out of the soil before disengaging the PTO.
Ensure that the PTO, driveshaft, and drive chains are working properly.
Move the tractor lift arms 7.5 to 10 cm (3 to 4 inches) closer to the aerator. Ensure
that the tractor has the capacity to lift the aerator.
Air is in the cylinder or lines and must be bled out.
•The crank pin nut has vibrated loose.
•The chains are too loose.
•The bolts on the bottom of the frame at the rear of the main arm have vibrated loose.
•Check the oil level in the gearbox.
The PTO shaft is too long for your tractor and should be cut to the correct length.
•Add weight to the front of the tractor.
•Check the tire pressure and adjust it as required.
•Do not store the aerator on the ground with tines installed.
•Do not run the coring head at high speed for an extended time when the tines
are out of the ground.
