FORM NO. 3318-401 GB MODEL NO. 09600—60001 & UP ® OPERATOR’S MANUAL HC 4000 AERATOR® To understand this product, and for safety and optimum performance, read this manual before starting operation. Pay special attention to SAFETY INSTRUCTIONS highlighted by this symbol.
Foreword The HC 4000 Aerator has advanced concepts in engineering and design, and if properly maintained, will provide excellent service. Since the Aerator is a high quality product, TORO is concerned about its future use and safety of the user. Therefore, anyone involved with the product, including the operator, should read and understand this manual. Major sections are.
Safety BEFORE OPERATING WHILE OPERATING 1. 9. 2. 3. Read and understand the contents of this manual and tow vehicle manual before operating the machine. Become familiar with all controls and know how to stop quickly. The power take-off drive of the aerator requires a tractor with operating speeds of 540 rpm and output power of 25 hp or higher. All safety shields for the tractor drive shaft must always be in place.
power to aerator, stop prime mover, shift into neutral and set parking brake. Lift safety/transport stops to full upright position and lower unit onto stops. MAINTENANCE 14. Before servicing machine, raise aerator, disengage power to aerator, shift prime mover into neutral and set parking brake. Lift safety/transport stops to full upright position and lower unit onto stops. Stop engine. Disconnect PTO shaft and hydraulic hose connection. 15. Ensure machine is in safe operating condition.

Specifications Type: Semi-mounted tow-behind, PTO-driven, deep coring mechanical turf/fairway aerator. Tire Scrapers: Removes soil build up from each wheel. Adjustable for desired clearance. Tractor Requirements: 18.6–33.6 KW (25–45 hp) @ 540 PTO rpm, category 1, three-point hitch with snubber chains to restrain side movement and a hydraulic system with “Lift” and “Float” control provisions.
for provisions for two tines. Turf Guards: Semi-rigid, mounted with compression spring floatation. Rear mounted roller, provides independent floatation and allows turf guard to follow turf grass contour. Adjustable roller scraper removes soil from roller. Cover: High-density polyethylene material mounted to unit with flexible draw latches to provide a shield from rotating components.
Before Operating CHECK 90° GEAR CASE OIL LEVEL 1. With machine on level surface, remove oil fill/dipstick plug from gear case (Fig. 1). 2. Oil level should be to mark indicated on dipstick. If oil is required, add SAE 80-90 (ISO 150/220) gear oil. 3. Install fill plug. CHECK GEAR CASE OIL LEVEL Figure 1 1. At front of aerator, remove (2) plugs from case ports (Fig. 2). 2. Oil level should be to top of each port. If oil is required, add SAE 80–90 (ISO 150/220) gear oil. 3.
To Check Tractor Ground Speed: 1. Find a test area and measure and mark off 30.5 meters. 2. Operate tractor engine at PTO speed of 540 rpm. Select a transmission gear and operate the tractor over the test area (with or without aerator). Record the time necessary to travel 30.5 m. Note: If tractor lacks a tachometer, measure PTO shaft rpm with a hand tachometer. 3. Make three passes and record the time intervals. Average operating time over 30.5 should be between 30–38 seconds.
2. Remove the lynch pins used to secure the driver and driven gears. 3. Install driver and driven gears matching indicated chart time and secure with lynch pin. Note: Number of gear teeth is stamped on the gear. 4. Install gear case cover and lower aerator cover. Verify timing of the aerator/tractor. Operation TRAINING PERIOD Before using the aerator, find a clear area to practice using the machine.
ver gear teeth quantity should be increased and driven gear teeth decreased; see gear selection chart. 5. Operate the machine again and repeat steps 1–4. IMPORTANT: Timing can sometimes be fine tuned by gradually regulating tractor tire pressure. Lowering tire pressure will provide closer spacing and raising tire pressure will increase the spacing. CAUTION: Do not exceed the maximum or minimum inflation pressures as recommended by tire manufacturer.
TRANSPORT OPERATION To begin transport operation, raise the aerator, disengage the PTO and set the parking brake. Raise safety/transport stops and lower aerator onto stops. To avoid loss of control, traverse steep inclines slowly, approach rough areas at reduced speed and cross severe undulations carefully. Important: Do not exceed transport speeds of 24 kmh on smooth level terrain. use slower speed for more adverse conditions.
OPERATING TIPS 1. Gradually engage PTO at low engine speed and throttle up to 540 PTO RPM before lowering aerator. 2. Make very gradual turns when aerating. Never make sharp turns. 3. If tractor “bogs” down when operating on hard ground or going uphill, raise aerator slightly until speed is regained, then lower again. 4. Do not aerate if ground is too hard or dry. Best results are obtained after a rain or when turf has been watered the previous day. 5.

Note: It is a good practice to lubricate grease fittings after washing machine. 4. To lubricate the center grease fitting on drive shaft assembly, the aerator must be in the raised (transport) position, to gain access thru slots in shields. CHECK GEAR CASE OIL LEVEL Every 25 hours operation, or seasonally, whichever comes first, check oil level in each gear case. 1. At front of aerator, remove (2) plugs from gear case ports (Fig. 11). 2. Oil level should be to the top of each port.
CHECK PICK-OFF GEAR CASE OIL LEVEL Every 25 hours operation, or seasonally, whichever comes first, check oil level in the pick-off gear case. 1. With the machine on a level surface, remove the gear case cover (Fig. 15). 2. The oil level should be to the center of the lower gear shaft. If the level is low, add SAE 80–90 (ISO 150/220) gear oil and install the cover. Figure 14 Note: Should major failure of pick-off gear case components occur, the gear oil will be contaminated and should be drained.
Maintenance CHECKING STOMPER ASSEMBLIES Within the first five hours of initial machine operation and after every 25 hours of operation thereafter, all stomper assemblies must be checked for excessive lateral play. This must be done or major machine component failure may result. 1. Grasp each stomper assembly at the bottom and try to move the assembly laterally in each direction (Fig. 16). Do not move fore and aft. There should be little or no movement of the assembly.
nance, the unit will need to be re-timed to ensure machine balance, equal loading of tine arms and optimum hole quality. There are two separate procedures to properly time the aerator gear cases. Use the following tips for each procedure when reassembling gear case. A. Timing upper and lower crank shafts on each individual gear case B. 1. The upper and lower crankshaft flywheels for each Tine arm must be assembled so the offset shafts are located in the same “clock” position.
