Fully slide together the PTO shaft tubes. Verify that the inside tube does not protrude into the cross and bearing section of the outer tube (Figure 16). If this happens, you need to cut off more of the inside tube—proceed to next step. 10.
Note: Cut off more of the inside tube if it all working conditions. During transport, when the drive line is not rotating, the telescoping tubes must have a suitable overlap to maintain alignment of the tubes and allow them to slide freely. protrudes into the cross and bearing section of the outer tube. 9 Installing the PTO Shield g237888 Figure 18 Parts needed for this procedure: 1 PTO shield Procedure 1. g237889 Figure 19 14.

1. Adjust the sway links on the lower lift arms to minimize side-to-side sway to a maximum of 25 mm (1 inch) at each side (Figure 28). g010804 Figure 26 1. Top holes Important: Do not lift the aerator higher than necessary when connecting the PTO. Lifting the machine too high will cause the PTO shaft knuckles to break (Figure 27). Shut off the PTO when lifting the aerator. You can operate the PTO up to a 25° angle, but never exceed a 35° angle when the aerator is at its highest position. 7.

Note: Refer to the traction unit operator's manual for additional adjustment procedures. 2. Clamping bolt Slide the new tines into the holes sized to fit the tines selected. Never use small diameter tines in the large diameter holes; the tines should fit closely in the hole.

area around the clutch free of flammable material and avoid prolonged slipping of the clutch. Slope Safety 3. Select a gear that produces a 1 to 4 km/h ( 0.8 to 2.5 mph) forward speed at the rated PTO speed of 400 to 460 rpm; refer to the operator's manual for the traction unit. 4. As you release the clutch and the traction unit moves forward, lower the aerator fully onto the roller(s) and increase engine speed to give a maximum of 400 to 460 rpm (460 on model SR72) at the PTO.
Hard Ground significant stress on the root zone of the turf. This stress can fracture the root zone and cause a lifting action to the turf. If lifting damage occurs, try one or more of the following: If the ground is too firm to obtain the desired aeration depth, the coring head can get into a bouncing rhythm. This is due to the hard pan that the tines are attempting to penetrate.
Adjusting the Tine Angle (Model SR72) moving the roller adjusting bolts to the desired position. 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. These holes are presets only; for instance, by using a 10-inch tine in the 12-inch position you may achieve a smoother finish; depending on the application.

Transport Operation are short or weak. You may want to experiment using another camber setting that will set the tines on more of an incline to keep from pulling soil out of the hole. To begin transport operation, raise the aerator and disengage the PTO. To avoid loss of control, traverse steep inclines slowly, approach rough areas at reduced speed and cross severe undulations carefully. • Do not aerate if the ground is too hard or dry.
2. Inspect for machine damage, oil leakage, and component and tine wear. Important: Repair all damages and worn components. 3. Grease PTO shaft joints and roller bearings; refer to Greasing the PTO Shaft and Roller Bearings (page 32). 4. Remove, clean, and coat the tines with oil. 5. Spray a light oil mist to coat the coring head bearings, crank, and damper links. 6. Clean and coat the springs with a dry lubricant like graphite or silicone.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 50 hours • Change the gearbox oil. Before each use or daily • • • • Inspect the drive chain tension Check the springs Clean and lubricate springs and tine mounting screws. Inspect the PTO for signs of wear. After each use • Inspect and clean the machine. Every 50 hours • Grease the bearings and PTO shaft • Check the gearbox oil. • Inspect bearings.

Inspecting/Adjusting the Drive Chain Service Interval: Before each use or daily and adjust the tension as needed. • Check the drive chain for wear and damage. Replace a worn of damage drive chain. • Check the drive chain tension.
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. 1.

Removing the Aerator from the Traction Unit 1. Stop the aerator on a level surface, not on a slope. 2. Disengage the PTO and engage the parking brake. 3. Raise the aerator roller(s) 7.5 to 15 cm (3 to 6 inches) off the ground. Place support blocks under the roller(s). 4. Shut off the engine and remove the key. 5. Before leaving the operator's seat, shut off the engine, remove the key, and wait for all moving parts to stop. 6. Remove the tines. 7. Install the storage stand. 8.
Troubleshooting Problem Solution The springs are breaking or not pulling back the head to normal position. Slow the PTO speed of the traction unit. The longer and heavier the tines, the greater the centrifugal force on the head. Check for crossed or broken spring wires. The tines produce elongated or picking holes. Adjust the angle of the tine or change the traction unit ground speed. Make sure that you can lower the aerator at least 5 cm (2 inches) below flat ground level to allow for undulation.
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. • Do not allow children to play on or around the stored machine.
