Adjusting the Tine Angle moving the roller adjusting bolts to the desired position. (Model SR72) Note: The factory ships the aerator in Position A. Set the camber bracket (Figure 38) to the correct position based on the tine length. The head stop is set to 1 of 5 predetermined positions by choosing the hole through which you bolt the adjustment rod.
Transport Operation are short or weak. You may want to experiment using another camber setting that will set the tines To begin transport operation, raise the aerator and on more of an incline to keep from pulling soil out disengage the PTO. To avoid loss of control, traverse of the hole.

Inspect for machine damage, oil leakage, and component and tine wear. Important: Repair all damages and worn components. Grease PTO shaft joints and roller bearings; refer to Greasing the PTO Shaft and Roller Bearings (page 32). Remove, clean, and coat the tines with oil. Spray a light oil mist to coat the coring head bearings, crank, and damper links.

Adjusting the PTO Clutch Service Interval: Yearly Before and after storage WARNING Friction clutches may become hot during use. Do not touch. To avoid the risk of fire, keep the area around the clutch free of flammable material and avoid prolonged slipping of the clutch.
Removing the Aerator from the Traction Unit Stop the aerator on a level surface, not on a slope. Disengage the PTO and engage the parking brake. Raise the aerator roller(s) 7.5 to 15 cm (3 to 6 inches) off the ground. Place support blocks under the roller(s).
Troubleshooting Problem Solution The springs are breaking or not pulling back Slow the PTO speed of the traction unit. The longer and heavier the tines, the the head to normal position. greater the centrifugal force on the head. Check for crossed or broken spring wires. The tines produce elongated or picking holes.
Storage Storage Safety • Park the machine on a level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine. • Store the machine on the storage stands positioned on a firm, level surface so that it does not sink or tip over.
