Figure 11 Park the traction unit on a level surface, shut off the engine, engage the parking brake, remove the key, and wait for all movement to stop before leaving the machine. 5. Visually inspect the traction unit for any loose hardware or any other possible problems.
3. If removed, install the upper 3-point link (Figure 16) to the traction unit. g265012 g265074 Figure 13 1. Hitch hardware (traction unit) Figure 16 3. Tongue (aerator) 2.

Attaching Aerator Position the aerator so that the lower-link arms of the traction unit line up with the lift-arm pins of the aerator (Figure 17). Model 44867 1. Lower the lower-link arms of the traction unit (Figure 14).
Installing the Tines Important: Install the tines only after attaching the aerator to the traction unit. 1. Start at the outside casting and install the tines as shown in Figure 20. g265124 Figure 18 1. Nut (3/4 inch) 4. Lift arms (aerator) 2. Jam nut (3/4 inch) 5. Bolt (3/4 x 4 inches) g029052 Figure 20 3. Upper 3-point link 7.

Using Model 44867 lock-bar bracket, and secure the lock pin to the bracket with the hair pin (Figure 22). 1. Start the traction unit engine and run it at a low speed. 2. With 3-point or remote-hydraulics control of the traction unit, slowly lower the aerator while the traction unit is slowly moving forward (Figure 23). Note: Moving the lock pin to stow/aerating position allows you to raise and lower the aerator while working at the job site. g265323 Figure 23 3.
Maintenance CAUTION If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the switch before you perform any maintenance. Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Maintenance Procedure • Check the tire air pressure. • Check the tines for wear. Every 40 hours • Grease the fittings. Every 100 hours • Check the main arm bushings.
g265328 Figure 26 Model 44867 Chassis Maintenance Checking the Main Arms Bushings Checking Tire Air Pressure Service Interval: Every 100 hours Model 44856 The 6 main arms pivot freely horizontally and vertically to allow the unit to follow the contour of the ground. A bronze bushing is pressed inside the pivot holes between the main arms and frame mounting brackets (Figure 28). Service Interval: Before each use or daily 1. Check the tire pressure (Figure 27). You should measure 413 kPa (60 psi).
D. Tighten the bolt (5/8 x 2 inch) and nut (5/8 inch) against the bushings, not the arms, to allow it to pivot freely. E. Adjust the spring tension; refer to Adjusting the Springs (page 16). Adjusting the Springs The purpose of the springs is to distribute the weight evenly and reduce the shock load on the pivot points. Adjust the springs evenly across to level the machine. Use the nuts at top of the spring rod to adjust the spring tension (Figure 29).
Storage 1. Raise the tines. 2. Stop the traction unit, shut off the engine, engage the parking brake, and remove the key. 3. Remove dirt and debris from the entire aerator. Clean the cores out of the tines. Important: You can wash the aerator with mild detergent and water. Do not pressure wash the aerator. g029056 4. Lubricate the aerator; refer to Lubrication (page 14). 5. Check the condition of the tines. Replace any broken or worn tines. 6. Check and tighten all bolts, nuts, and screws.
