Trouble Shooting
Problem
Solution
Springs are breaking or not pulling back the
head to normal position.
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.
Holes are elongated or picking.
Adjust the angle of the tine or change the tractor ground speed. Make sure that the
aerator can be lowered at least 2 inches below flat ground level to allow for undulation.
Tines are hitting the ground with an erratic
pattern.
•
Check for crossed or broken spring wires.
•
Slow the PTO speed of the tractor.
PTO clutch slips excessively.
Adjust tines to a shallower depth. Review clutch adjustment procedure. Replace
PTO clutches.
Turf is pulling up with coring tines.
Shallow-rooted turf may require solid tines the first time.
The soil is too hard for full penetration.
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 desired depth.
Coring tines are breaking.
You are trying to get too much depth for the soil condition. See above and aerate to
a shallower depth.
Tines will not stay in the head.
Tighten the tine holder bolts; do not use jam nuts or impact wrench. If the bolt will not
hold the tine, replace it.
Tines pull the soil up when the machine is
raised.
Raise the machine part of the way out of the soil before disengaging the PTO.
The machine will not turn.
Make sure the PTO, drive shaft and drive chains are working properly.
The tractor has difficulty lifting the aerator.
Move tractor lift arms 3” (76.19 mm) to 4” (101.6 mm) closer to the aerator. Make
sure the tractor has the capacity to lift the aerator.
The hydraulic top link cylinder is spongy. (It
“gives” and moves in and out a short span
when force is applied.
Air is in the cylinder or lines and must be bled out.
Machine is noisy or knocking.
•
Crank pin nut has vibrated loose.
•
Chains are too loose.
•
Bolts on the bottom of the frame at the rear of the main arm have vibrated loose.
•
Check oil level in gearbox.
The hydraulic top link cylinder can not be fully
retracted (PTO shaft jams).
The PTO shaft is too long for your tractor and should be cut to the correct length.
The tractor is difficult to steer when in transport.
•
Add weight to the front of the tractor.
•
Check tire pressure and adjust as required.
Camber bracket damage
•
Do not store the aerator, on the ground, with tines installed.
•
Do not run the coring head, for an extended time at high RPM, when the tines
are out of the ground.
