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. Use Decal 1 Apply to cutting deck for CE Parts Catalog 1 Operator’s Manual 1 Read before operating the machine. Registration Card 1 Fill out and return to Toro.
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 m–5421 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.
Mow When Grass is Dry Operation Mow either in the late morning to avoid the dew, which causes grass clumping, or in late afternoon to avoid the damage that can be caused by direct sunlight on the sensitive, freshly mowed grass. Note: Determine the left and right sides of the machine from the normal operating position. Operating Tips Select the Proper Height-of-Cut Setting to Suit Conditions Blade Selection Remove approximately one inch or no more than 1/3 of the grass blade when cutting.
Optional Equipment Configuration Cons Pros Applicatio tion High Lift Parallel Sail Blade Standard Angle Sail DO NOT USE Blade WITH MULCHING BAFFLE Grass Cutting: .75 to 1.75 inch Height of Cut Recommended in most applications May work well in light or sparse turf Grass Cutting: 2.00 to 2.50 inch Height of Cut Recommended for thick or lush turf Recommended for light or sparse turf Grass Cutting: 2.75 to 4.
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 and disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Greasing the Bearings 4. Release latch rod (Fig.
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. Inspecting the Blade Plane 1 1. Remove hydraulic motor from cutting deck and remove cutting deck from tractor. 1 2. Use hoist (or minimum of two people) and place cutting deck on flat table. Figure 8 1. Motor mounting screws 3. Mark one end of blade with paint pen or marker. Use this end of blade to check all heights. 3.
Adjusting the Blade Plane Removing the Cutter Blade Start with front adjustment (change one bracket at a time). 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. Remove height-of-cut bracket, (front, left, or right) from deck frame (Fig. 11). 2. Adjust .060 in.
Inspecting and Sharpening the Blade SHARPEN AT THIS ANGLE ONLY 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. On the Groundsmaster 3500, secure cutting deck service latch. END VIEW Figure 14 2. Examine cutting ends of the blade carefully, especially where the flat and curved parts of the blade meet (Fig. 13-A).

Alternate tightening sequence of 1/4 in. capscrews to pull seal out of housing. Using a 1/4 in. thick, 3 in. x 3 in. square piece of steel and the following specifications, make a seal removal tool (Fig. 16). Note: Seal will be destroyed when servicing the rear roller. Do not attempt to re-use these seals.
7. Press new seal flush to .030 in. recessed into housing. Repeat for other side. 5. Verify that there is no more than a .060 in. gap between roller assembly and the roller mount brackets of the deck frame. If there is a gap over .060 in., install enough 5/8 in. diameter washers to take up the slop. Servicing the Front Roller 6. Secure mounting bolt to 80 ft.-lb. (108 N⋅m). Inspect front roller for wear, excess wobble or binding. Service or replace roller or components if any of these conditions exist.
