Attach the arms of the tractor to the hitch pins on the aerator lift arms. 4. Attach the tractors stabilizer bar to the 3/4"x 4" bolt on the top of the lift arms.
LUBRICATION BEARINGS (Fig. 3) The aerator has six serif sealing bearings that must be lubricated with a No. 2 Lithium based grease. IMPORTANT: Lubricate the bearings as often as necessary to maintain a slight leakage on the seals. Too much grease can cause overheating. WHEELS AND WHEEL BEARINGS AERATOR 686 (Fig. 3) Grease firings weekly or every 40 operating hours. Use a No. 2 Lithium based grease. GREASE FITTINGS AERATOR 686 (Fig. 3) 1. Grease the grease firings weekly or every 40 operating hours.
MAINTENANCE MAIN ARMS {Fig. 4 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 arm and mainframe. The bronze bushing is 1/8" longer than the thickness of both plates combined. The 5/8 x 2" bolt should be tightened against the bushings, not the arms to allow it to pivot freely. The bronze bushings should be checked every 100 hours of operation for signs of wear.
MAINTENANCE TINE WEAR (Fig. 5) To obtain maximum aerating performance always check the tines for wear before every use. Severely worn Ines are easy to bend or break and will leave the cores in the ground. Ses Fig. 5 for examples of tine wear. (Continued) Always clean cores out of tines before storage. Cores left in tines for extended prods can cause piing on the inside of the tine. The pits in the tne keep the core from ejecting. Needs To Be Replaced.
STORAGE 1. Thoroughly clean the aerator, 2. Inflate tees to 60 PSI. 3. Check all fasteners. Tighten as necessary. 4. Check the condition of the tines. Replace any broken or worn tines.
