Warning signals a hazard that may cause serious injury or death if you do not follow the recommended precautions. • Do not operate machine while wearing sandals, tennis shoes, sneakers or shorts. Also, do not wear loose fitting clothing which could get caught in moving parts. Always wear long pants and substantial shoes. Wearing safety glasses, safety shoes, ear protection and a helmet is advisable and may be required by some local ordinances and insurance regulations.
• Reduce speed on rough roads and surfaces. Maintenance • Independent brakes should always be locked together when on the road. • Before making adjustments or performing maintenance on the aerator, switch off the engine, stop the PTO and apply the hand brake before dismounting from the tractor. Be sure the aerator is on the ground or lowered onto the rear castor/safety stand. PTO Shaft • For all PTO shaft steel parts (tubes, bearings, joints etc).

Setup Note: Determine the left and right sides of the machine from the normal operating position. Loose Parts Chart Note: Use this chart as a checklist to ensure all parts necessary for assembly have been shipped. If any of these parts are missing, total setup cannot be completed. Description Qty.
Connect Upper Link Install Side Guards Note: Front of aerator must be vertical or angle forward slightly while operating for best aeration hole quality (Fig. 3).This angle will change when depth adjustments are made. Adjust upper link to control this angle. Refer to Operation, page 17 for additional information. 1. Remove 4 nuts, lockwashers and washers loosely secured to each bottom end of aerator frame. 2. Position appropriate side guard (left or right) onto mounting studs (Fig. 5).
Connect PTO Shaft dimension in step 3, the PTO shaft is too long, proceed to step 5. If there is enough clearance to allow PTO shaft to collapse, proceed to step 10. 1. Connect PTO shaft to gearbox input shaft (Fig. 7). 1 2 1 1.5” (37 mm) Figure 6 1. PTO shaft Figure 7 5. Use the following calculation to establish how much shorter the shaft must be, when connected, to ensure a clearance of 1.5 inches (37 mm). 1. PTO shaft 2. Safety chains 2.

Mount Castor/Safety Stand Note: Use castor wheel to move aerator around on a hard surface, as aligning to tractor for installation or for storage. Level aerator by adjusting roller until the point of the depth adjustment arrow is just above the side guards. 1. Remove bolt and nut securing rear castor/safety stand tube to shipping pallet (Fig. 8). Retain bolt and washer for installation of castor wheel. 2 2 1 1 Figure 8 1. Shipping pallet Figure 10 2.

links, it is recommended that washers be installed between the lower link arm and lynch pin to reduce the over hung load on the lift pins. Note: Refer to tractor operator’s manual for additional installation and adjustment procedures. Level Aerator Side–to–side 1. Park tractor and aerator on a level, firm surface. Make sure both depth gauges are set at the same setting. 1 2. Place level on top of aerator hood to check for level side-to-side (Fig. 12). 1 Figure 13 1.
Mount Turf Guards A wide selection of turf guards are available for the aerator. Choose the required turf guards per accessory chart on page 13. 2 1. Loosen nuts securing turf guard clamps to turf finger tool bar (Fig. 14). 5 3 1 Figure 15 4 2 1. Spacer location ( 1 each end) 1 B. Pivot turf finger bracket upward and insert a washer onto each stud. Figure 14 1. Turf guard 2. Turf finger tool bar 3. Turf guard clamp 2. Roller scraper tab C. Pivot turf finger downward onto studs and check angle.
Adjust Turf Guards 9. Loosen locking nut and rotate adjusting link to release tension between aerator and tractor. Before starting your new aerator, remove the rear castor stand and lower the machine on the 3–point linkage until the depth control roller is resting on the ground. From the rear of the machine, check that the tines line up exactly with the center of the gaps in the turf guards. Install the correct turf guards (Fig. 16), if necessary. 10.

Controls Depth Adjustment Handles Remove lynch pins, rotate handles to raise or lower tines to desired depth and replace lynch pins (Fig. 17). 1 1 Figure 18 1. Depth guide 2 Figure 17 1. Depth adjustment handle 2. Lynch pin Depth Guides Depth guides (1 thru 27) are provided to give equal increments for adjustment. The numbers do not relate to measurements of depth as this changes with tine type and amount of tine wear. Adjustment between two numbers will give approximately .
Operation Adjust Tine Depth To adjust the working depth of the tine, proceed as follows: 1 1. Remove the lynch pin from each depth adjust handle (Fig. 19). 1 Figure 20 1. Depth guide Important If a large change in height is required, adjust each leg by a small amount to ensure the roller legs are adjusted as evenly as possible. Note: Remember when depth changes are made, you will need to adjust the top link length to give the correct machine angle. Refer to Connect Upper Link, page 8.
4_ 90_ “H1” “H2” Figure 21 Figure 23 In some instances, angling the aerator forward may improve hole quality but will also reduce aeration depth and gain clearance with the turf guards. A forward angle of approximately 4_ is a good initial setting. Use a magnetic based angle indicator to determine the forward angle, or use the following procedure: D. Adjust upper link until the difference between “H1”–“H2” matches desired forward angle of aerator (See Angle Chart below). A.
Depth Chart Guide Note: In instances where sufficient root growth exists, the turf guards may be removed to attain maximum depth without damaging the turf guards. • Gear Selection Note: For future reference, record the upper link length that achieves the desired operating angle. Note: Refer to tractor operator’s manual for operating instructions.
2. At a low tractor engine rpm, engage the power take off (PTO) clutch to start the aerator working. As the tractor travels forward with the PTO engaged and the machine lowered, a series of holes are created in the turf surface. Important Do not operate aerator at 540 PTO rpm when lifted out of the ground. This machine can be damaged if operated at full speed without the tines working in the turf.
7. Always check/adjust top link whenever aeration depth is changed. The front of the aerator should be vertical or angled slightly forward. Experiment with depth and angle to achieve best hole quality. Caution Do not exceed the maximum or minimum tractor tire inflation pressures as recommended by tire manufacturer. Note: Once optimum hole quality is attained, record depth setting and the upper link length for future reference.
Maintenance Lubrication Greasing Bearings and Bushings The main working bearings of the aerator are sealed for life and require no maintenance or lubrication. This drastically reduces the maintenance required and eliminates the risk of grease or oil being dropped onto the turf. Figure 26 There are grease fittings that must be lubricated with an SAE multi–purpose, high–temperature grease with high pressure (EP) performance or SAE multi–purpose lithium base grease.
Torque Taper Lock Assembly 6. Install setscrews in taper lock bushing and secure. Torque setscrews in an alternating method to 37 ft–lbs (50 Nm). After first 10 hours of operation torque set screws securing taper lock bushings to driven pulleys to 37 ft. lbs. (50 N⋅m) (2 each pulley) (Fig. 29). 7. Remove M12 bolt and replace the assembly washer with original ”thin” washer. Re–torque M12 bolt to 59–73 ft–lbs (80–100 Nm). 8. Re–install belt tension.
B. Rotate hex on top of idler tube until the bottom of the rubber boot is between the two grooves in the guide tube. At this position the spring will be compressed to a length of 3 inches (76 mm). 4 5 2 7 C.

13. Route new belts over drive shaft and onto pulleys. 8. Remove (8) capscrews and flat washers securing end cover and bearing housing to end of aerator frame (Fig. 34). 14. Reinstall end cover onto drive shaft. At location marked on frame, loosely secure end cover to aerator frame with (8) capscrews and flat washers removed. 15. Reinstall bottom of tine arm to bottom links or rotalink arm with fasteners removed. 1 16. Reinstall top of tine arm to pulley with screw, lock washer and flat washer. 17.
