Height of Cut Adjustment The height–of–cut is adjustable from 1 to 5 inches (25 to 127 mm) in 1/2 inch (13 mm) increments. 1. Start engine and raise cutting. Stop engine after cut- ting unit is raised. 2. Remove front snapper pins from castor arms and slide castor wheel assembly up or down.
Skid Adjustment 1. Adjust skids by loosening flange nuts, positioning as desired and re–tightening flange nuts. 1 2 Figure 8 (Rear Discharge) 1. Skid 2.
3 Gage Wheel Adjustment (Rear Discharge Cutting Unit) Note: If cutting unit is to be used in the 1 inch (25 mm) height–of–cut setting, cutting unit gage wheels must be positioned in highest position. 1. Adjust gage wheels by loosening locking hub, posi- tioning gage wheel support at desired height and re– tightening locking hub.
Deck Pitch Adjustment Deck pitch is the difference in height–of–cut from the front of the blade plane to the back of the blade plane. TORO recommends a blade pitch of .25 inches (6 mm). That is the back of the blade plane is .25 inches (6 mm) higher than the front.
Service and Repairs while performing maintenance, shut engine off and remove key from ignition switch. CAUTION T o prevent accidental starting of the engine, Check Gear Box Lubricant The gear box is designed to operate with SAE 80–90 wt.

Groundsmaster 3000/3000–D Page 1 1 – 10 72 inch Cutting Units Disconnect Cutting Unit From T raction Unit Note: Implements are heavy and may require two people to handle. 1. Start tractor and raise deck to highest possible posi- tion and turn off engine.
Connect Cutting Unit to T raction Unit 1. Center traction unit in front of cutting unit on any flat hard surface. 2. Raise seat and open needle valve. This allows lift arms to float freely . 3. Adjust lift arms heights making sure that the ma- chined surface on top of each traction unit lift arm is par- allel to ground (Fig.
Drive Belt Replacement The blade drive belt, tensioned by the spring loaded idler , is very durable. However , after many hours of use, the belt will show signs of wear . Signs of a worn belt are: squealing when belt is rotating, blades slipping when cutting grass, frayed edges, burn marks and cracks.
Front Castor Fork Bushing Service The castor forks have bushings pressed into the top and bottom of the casting and after many hours of operation, the bushings will wear . T o check the bushings, move castor fork back and forth and from side to side. If castor spindle is loose around the bushings, bushings are worn and must be replaced.
Castor Wheel and Bearing Service The castor wheel rotates on a high–quality roller bear- ing. Even after many hours of use, provided that the bearing was kept well–lubricated, bearing wear will be minimal. However , failure to keep bearing lubricated will cause rapid wear .
Cutter Blade Removal 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 replace- ment blades made by other manufacturers because they could be dangerous.
Inspecting and Sharpening Blade 1. Raise cutting unit to highest position, shut the en- gine off and engage the parking brake. 2. Remove hair pin cotters and clevis pins securing height–of–cut chains to rear of deck. 3. Rotate front of deck upward and insert latch rod into front hole (service position) in latch plate.
Blade Spindle Service Removing Spindle Housing Assembly 1. Lower the cutting unit, shut the engine off and engage the parking brake. 2. Remove deck covers from top of cutting unit. Release belt tension. Remove belt from spindle to be serviced. 3. Start the engine and raise the cutting unit.
Installing Spindle, Bearings and Seals Into Spindle Housing IMPORT ANT : If a new spindle housing is being used, new bearings and matched snap ring set must be installed; see step 1 below . Never use old bearings, spacer , and snap ring with a new spindle housing.
Correcting Cutting Unit Mismatch If there is mismatch between the blades, the grass will appear streaked when it is cut. This problem can be cor- rected by making sure the blades are straight and all blades are cutting on the same plane. 1. Using a 3 foot (1 m) long carpenters level, find a lev- el surface on the shop floor .
