Safety – Drive slowly and watch for holes or other hidden hazards. – Do not drive close to a sand trap, ditch, creek, or other hazard. Before Operating – Reduce your speed when making sharp turns and when turning on hillsides. • Read and understand the contents of this Operator’s Manual before operating the machine. Become familiar with all of the controls and know how to stop quickly.
the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. • Before disconnecting or performing any work on the hydraulic system, all pressure in the system must be relieved by stopping the engine and lowering the blower to the ground. • Perform only those maintenance instructions described in this manual. If major repairs are ever needed or assistance is desired, contact an Authorized Toro Distributor.
Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Specifications Note: Specifications and design subject to change without notice. General Specifications Tractor Requirements The tractor should be 30 HP or over and a PTO speed of 540 RPM. Aerating/Thatch Swath 48”, blade tip to blade tip. Offset mounting covers the tire tread Hitch Standard 3 point hitch. Drive PTO to gearbox, sealed bearing and sprocket, #H80 chain to blade shaft.
Setup dimension in step 8, 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. Attach Aerothatch to Tractor 1 Important The tractor should be 30 HP or over, a PTO speed of 540 RPM and have a well operating three point hitch. Do not operate at a faster speed because the blades, sprockets, gearbox and PTO will be damaged. 1.5” (37 mm) 1. Lower the three point hitch arms on the tractor. 2.
4. Repeat the procedure on the opposite side. Important Always set both skids at the same depth. Uneven skid height will cause a variance in cutting depth across the blade shaft.
Operating Instructions Important The tractor should be 30 HP or over, a PTO speed of 540 RPM and have a well operating three point hitch. Do not operate at a faster speed because the blades, sprockets, gearbox and PTO will be damaged. 1. Start tractor engine and run at a low RPM. Using the tractor s hydraulics raise the Aerothatch high enough to clear the ground. 2. With the tractor engine at idle, engage PTO and gradually increase PTO speed to 540 RPM. 3. Select tractor forward speed.
Lubrication Bearings PTO The Aerothatch 83 has two self sealing bearings that must be lubricated with a No. 2 Lithium based grease (Fig. 5). Grease the PTO fittings weekly or every 40 operating hours. Use a No. 2 Lithium based grease (Fig. 5). Important Lubricate the bearings after every 40 hours of operation or weekly to maintain a slight leakage on the seals. Too much grease can cause overheating. Gearbox Check lubricant level in gearbox every 40 hours of operation (Fig. 5).
Maintenance Drive Chain Adjustment Blade/Disc Alignment The drive chain (Fig. 6) is adjusted to allow a 1/4” deflection. Do not over tighten the chain because it will wear rapidly. If chain is to loose, the sprocket will wear. When replacing the blade or disc shaft, use the dimensions shown as a reference to keep the disc shaft in line with the blade shaft (Fig. 7). 1. Remove the chain guard. This is very important when seeding, allowing the seed to fall into the blade groove for maximum germination.
Changing Blade Configuration Replace thatcher blades when they are worn to less than 10 inch diameter. Blades should be orientated, on the reel shaft, so they rotate in a spiral. Each blade should be positioned 90 degrees forward, of the next blade, on the reel shaft (Fig. 8). Whenever the blade and shaft assembly is disassembled, make sure to re–torque the nut to 450 ft.–lb and bend the locking tab over the nut. Figure 8 Reverse blade operation, can be achieved, by reversing the mounting of the gearbox.
Thatching and Seeding Seeding, Clean Groove No Thatching Thatcher is set up from the factory this way. Gearbox must be mounted, as shipped from the factory, so output shaft is rotating counter–clockwise (as you look at the gearbox). Thatching blades must be removed and turned around or the Optional Blade Shaft Assembly, PArt No. 100–7734, must be installed.
Trouble Shooting Condition Excessive Vibration Cause 1. Blades too deep (extremely dry soil) 1. Change blade depth. 2. PTO speed too low. 2. Bring PTO speed up 540rpm. 3. Check for missing blades. 3. Replace blades 4. Blade shaft bent. 4. Bring PTO speed down as low as possible and watch rotation of blade shaft for wobble or turn off Aerothatch and set on level surface then measure from floor to blade, rotate shaft to several positions, measure, compare dimensions. Replace blade shaft if necessary.
Storage 1. Thoroughly clean the Aerothatch. 2. Check all fasteners. Tighten as necessary. 3. Grease or oil all grease fittings and bearings. Wipe off excess lubricant. 4. Check the tension and condition of the drive chains. Adjust the tension if necessary and apply a heavy coating of grease to the chains. 5. Fill the gearbox with oil. See Lubrication section.
