Setup Note: Determine the left and right sides of the machine from the normal operating position. Loose Parts Note: Use this chart as a checklist to ensure that all parts have been received. Without these parts, total setup cannot be completed. Description Qty. Decal 1 Parts Catalog 1 Operator’s Manual 1 Adjusting the Carrier Frame (Groundsmaster 3500 only) Use Apply to cutting deck for CE Read before operating the machine.
Adjusting the Height of Cut Important This cutting deck often cuts approximately 1/4 inch lower than a reel cutting unit with the same bench setting. It may be necessary to have these rotary cutting deck’s bench set 1/4 inch above that of reels cutting in the same area. Important Access to the rear cutting units is greatly improved by removing the cutting unit from the tractor.
Installing the Mulching Baffle (Optional) 1. Thoroughly clean debris from mounting holes on rear wall and left side wall of chamber. 2. Install mulching baffle in rear opening and secure with 5 flange head screws (Fig. 5). 1 Figure 5 1. Mulching baffle 3. Verify that mulching baffle does not interfere with either tip of blade and does not protrude inside the surface of the rear chamber wall. Warning Do not use the high lift blade with the mulching baffle.
Operation After Operating To ensure optimum performance, clean underside of mower housing. If residue is allowed to build up in mower housing, cutting performance will decrease. Note: Determine the left and right sides of the machine from the normal operating position. Operating Tips Blade Selection Standard Combination Sail This blade was designed to provide excellent lift and dispersion in almost any condition.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition before you do any maintenance. Greasing the Bearings Each cutting deck has two grease fittings per rear roller If machine is operated under normal conditions, lubricate rear roller bearings (Fig. 7) with No.
Cutting Deck Service Latch (Groundsmaster 3500–D only) When servicing cutting decks, use the service latch to prevent injury. 1. Center cutting deck sidewinder with the traction unit. 1 2. Raise cutting decks to transport position. 1 3. Set parking brake and turn off machine. Figure 9 4. Release latch rod (Fig. 8) from front carrier frame retainer. 1. Motor mounting screws 3. Remove lynch pin or retaining nut (GM4700 only) securing deck carrier frame to lift arm pivot pin (Fig. 10). 1 1 Figure 8 1.
Blade Plane Adjusting the Blade Plane The rotary deck comes from the factory preset at 2.00 inch height-of-cut and blade rake of 0.310 inch. The left-hand and right-hand heights are also preset to within ±0.030 inch of the other. Start with front adjustment (change one bracket at a time). The cutting deck is designed to withstand blade impacts without deformation of the chamber. If a solid object is struck, inspect the blade for damage and blade plane for accuracy. 2. Adjust .060 in. shims and/or .
Removing the Cutter Blade Inspecting and Sharpening the Blade The blade must be replaced if a solid object is hit, the blade is out of balance or if the blade is bent. Always use genuine Toro replacement blades to be sure of safety and optimum performance. Never use replacement blades made by other manufacturers because they could be dangerous. 1. Raise cutting deck to highest position, shut the engine off, and engage the parking brake. Block cutting deck to prevent it from falling accidentally.
SHARPEN AT THIS ANGLE ONLY 3 2 END VIEW Figure 15 4. To check blade for being straight and parallel, lay blade on a level surface and check its ends. Ends of blade must be slightly lower than the center, and cutting edge must be lower than the heel of the blade. This blade will produce good quality of cut and require minimal power from the engine. By contrast a blade that is higher at the ends than the center, or if cutting edge is higher than the heel, the blade is bent or warped and must be replaced.
