Note: If an extension block is installed and the cylinder needs to be retracted to be installed, the aerator tine heads will get closer to the ground. Install the extension blocks as follows: A. Remove the cotter pin and pin securing the standard connecting link to the cylinder (Figure 5). Remove the connecting link from the cylinder. B. Install the required length extension block to the cylinder with the pins previously removed (Figure 5).

8 Fitting the PTO Shaft Parts needed for this procedure: 1 PTO shaft Procedure g010803 Figure 10 1. Breakage will occur here. 1. Park the tractor and aerator on a level surface. 2. Raise the aerator completely and fully retract the hydraulic top link cylinder or upper link (Figure 11). 7 Checking the PTO Angle No Parts Required g010798 Procedure Figure 11 Important: Ensure that the tines are removed before performing this operation. 3.
Example: 14 cm (5.50 inches) plus 1.2 cm (1/2 inch) equals 15 cm (6.00 inches). g010807 Figure 13 5. 9. Slide the PTO shaft tubes together until they are fully collapsed. Verify that the inside tube does not protrude into the cross and bearing section of the outer tube (Figure 16). If this happens, more will have to be cut off the inside tube, to correct the problem. Proceed to next step. 10.
9 Installing the PTO Shield g237888 Parts needed for this procedure: Figure 18 1 PTO shield Procedure 1. Remove the 4 bolts, lock washers, and flat washers secured to the rear of the aerator gearbox (Figure 22). g237889 Figure 19 14. Using the dimensions determined in step 11, locate, mark and cut off just the safety shields to expose the tubes (Figure 20 and Figure 21). g010849 Figure 22 g237890 Figure 20 1. PTO shield 2.

10 Connecting the PTO Shaft Parts needed for this procedure: 1 Pin (supplied with PTO shaft) 1 Nut (supplied with PTO shaft) Procedure Note: You can open the access panel (Figure 22) to g007328 ease the removal and installation of the PTO shaft mounting fasteners. 1. Remove the pin and nut from the PTO shaft (Figure 23). 2. Connect the clutch end of the PTO shaft to the aerator gearbox input shaft with pin and nut previously removed (Figure 23). The pin can be inserted only one way. Figure 24 1.
The PTO shaft should be as straight as possible to the tractor PTO shaft. Adjust the sway links on the lower lift arms to minimize side-to-side sway to a maximum of 25 mm (1 inch) on each side (Figure 28). g010804 Figure 26 1. Top holes Important: When connecting the PTO, be sure that the aerator is not being lifted higher than is necessary. Lifting the machine too high will cause the PTO shaft knuckles to break (Figure 27). Never leave the PTO turning when the aerator is lifted.

Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.
Training Period • Never carry passengers on the machine and keep bystanders and pets away from the machine during operation. Before using the aerator, find a clear area and practice using the machine. Operate the tractor at recommended gear settings and PTO drive speeds and become thoroughly familiar with machine handling. Practice stopping and starting, raising and lowering the aerator, disengaging the PTO drive and aligning the machine with previous passes.
5. surveying the site. Always use common sense and good judgment when performing this survey. Review the slope instructions listed below for operating the machine on slopes and review the conditions to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine. Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction.
Aeration of soil types built on top of hard sub soils (i.e. sand/soil cap placed over rocky ground) can cause undesired hole quality. This is caused when the aeration depth is greater than the soil cap and the sub soil is too hard to penetrate. When the tines contact this sub soil the aerator may lift and cause the top of the holes to become elongated. Reduce the aeration depth sufficiently to avoid penetration into the hard sub soil.
3. Models SR54, SR70, and SR72 Release the spring tension to the tine head (Figure 39). Start the tractor engine and operate the tractor spool valve to check the extend and retract motion of the hydraulic top link. Note: Reverse the hose connections, at the tractor, if they do not agree with the tractor control operation. The letters on the decal do not correspond to a particular depth.
4. Remove the nut securing the spring mounting post bolt to the linkage arm (Figure 42 or Figure 43). steep inclines slowly, approach rough areas at reduced speed and cross severe undulations carefully. Important: Do not exceed transport speeds of 24 km/h (15 mph). After Operation Safety • Keep all parts of the machine in good working • condition and all hardware tightened. Replace all worn, damaged, or missing decals.
link to keep from hammering the turf with the tine heads. In some cases, you may not achieve the best results from using the preset holes in the camber brackets, especially where the grass roots 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. • Do not aerate if the ground is too hard or dry. Best results are obtained after a rain or when the turf has been watered the previous day.
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 chain tension Check the springs Clean and lubricate springs and tine mounting screws. Inspect the PTO for signs of wear. Every 50 hours • • • • Grease the bearings and PTO shaft Check the gearbox oil. Inspect the chain tension Inspect bearings. Every 500 hours • Change the gearbox oil.
g010861 Figure 46 O-ring chain — Do not lubricate the chain. Important: Bearings rarely fail from defects in materials or workmanship. The most common reason for failure is moisture and contamination working its way past the protective seals. Bearings that are greased rely upon regular maintenance to purge harmful debris from the bearing area. Sealed bearings rely on an initial fill of special grease and a robust integral seal to keep contaminants and moisture out of the rolling elements.
Checking the Gearbox Oil 2. Remove the vent/fill plug to relieve air draw. Service Interval: Every 50 hours 3. Position a drain pan under the drain plug and remove the plug. The gearbox is filled with 80W–90 gear oil or equivalent. Allow the gearbox to cool before checking the oil level. 1. Clean debris from the fill plug and check plug to avoid contamination. 2. Remove the check plug from the gearbox (Figure 47).
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. At the end of the season, back off each of the clutch nuts 2 turns (Figure 50). g010863 Figure 48 Models SR54, SR54-S, SR70, and SR70-S 1. Drive chain 2. Jam nut 3. Jam rod g010847 Figure 50 1.

Removing the Aerator from the Tractor 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 on the tractor, 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 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 5 cm (2 inches) below flat ground level to allow for undulation.
Storage Storage Safety • Store the machine on the storage stands positioned on a firm, level surface so that it does not sink or tip over. • Store the machine away from areas of human activity. • Do not allow children to play on or around the stored machine. Storing the Machine At the end of an aerating season or when the aerator will not be used for a long period, it is good practice to carry out the following preventative maintenance. 1.
