Introduction This manual uses two other words to highlight information. Important calls attention to special mechanical information and Note: emphasizes general information worthy of special attention. Read this manual carefully to learn how to operate and maintain your product properly. The information in this manual can help you and others avoid injury and product damage. Although Toro designs and produces safe products, you are responsible for operating the product properly and safely.
• NEVER carry passengers on the Top Dresser and keep everyone away from the areas of operation. – If ever unsure about safe operation, STOP WORK and ask your supervisor. • When loading with sand, distribute load evenly. Operate tow vehicle with extra caution when the hopper is full of sand. Keep load balanced to prevent it from shifting. • Keep hands and feet out of hopper when unit is operating or engine is running on tow vehicle.

4. Route wire harness’ along tongue and secure to tongue with wire connectors. Before Operating 5. Plug controller harness connector into topdresser wire harness connector. Route to operator’s position and secure along frame rail. Check Hydraulic System Fluid Note: Wire harness has removable connectors which allow permanently installing portion on vehicle, and leaving the other portion with topdresser plugged in to the solenoid. The machine’s reservoir is filled at the factory with approximately 2.
Note: Mobil EAL224H and most other hydraulic oils are almost colorless, making it difficult detect leaks. A non–toxic dye additive, such as food coloring, can be added to improve visibility. Do not use hydraulic oil dyes as they may be toxic. organisms when exposed to air. Nonetheless, spillage of Mobil EAL 224H should be handled similarly to currently accepted methods for conventional mineral oil spills. Mobil EAL224H does not contain hazardous substances reportable under CERCLA.
Operation • Top dressing works best at 2 to 8 miles per hour (mph). The TopDresser 2500 compensates for variations in travel speed, and will give consistent distribution, even if travel speed changes during a pass across the green. The operator/superintendent should make a gate setting selection (variable in 1/8 increments to 13) and make a first pass to determine if application rate is acceptable.
• Before servicing or making any adjustments to the top dresser: Warning – Stop the tow vehicle and set the parking brake. Tipping or rolling the tow vehicle on a hill will cause serious injury. – Shut off the tow vehicle’s engine and remove key from ignition. If engine stalls or you lose headway on a hill, never attempt to turn tow vehicle around. • Keep all nuts, bolts and other fasteners tightened securely. Replace any parts removed during servicing or adjustments.
• Safe operation begins before taking the top dresser out for a day’s work. Read and understand the operating instructions in the Toro Workman or other tow vehicle operator ’s manual before using the topdresser. Danger As a general rule, position the weight of the load evenly from front to rear and evenly from side to side. Caution Transporting or topdressing with a full load can cause shifting of the sand.
Cold Weather Operation Although limited by traction of drive tires, the Topdresser 2500 may be used in cold weather, with certain limitations, to apply a salt/sand mixture on pavement for ice control. The PVC conveyor belt material becomes very stiff in cold weather and requires more power to operate belt. The life of the belt is reduced by approximately 50% when operated below temperatures of 40_ F (5_ C). Under no conditions should the topdresser be operated below temperatures of 20_ F (–7_ C). 1.
Maintenance Jacking Topdresser Lubrication Any load material must be removed from hopper before working under raised topdresser. The Topdresser 2500 has 13 grease fittings that must be lubricated with a No. 2 Lithium based grease. Lubricate annually or after every 200 hours of operation. Do not work under topdresser without jack stands supporting it. The jacking points on the topdresser are the skids. Pivot wheels up or down to expose wheel bolts.
3. Lubricate new filter gasket. 4. Assure filter mounting area is clean. Screw filter on until gasket contacts mounting plate. Then tighten filter one–half turn. 1 5. Check for leaks by towing machine to power the hydraulic system. Checking Hydraulic Lines And Hoses Inspect hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration and chemical deterioration. Make all necessary repairs before operating. Figure 13 1.
Tensioning Drive Chains The chains should be tensioned so they deflect 1/8”. Do not over tighten, this will cause chain wear. Do not operate with a loose chain, this will cause sprocket wear. Conveyor Belt Chain 1 1. Remove chain cover (Fig. NO TAG). Figure 15 1. Bearing housing 2. Loosen nuts securing brush motor (Fig. 16) to left side of machine. 1 Figure 17 1. Chain cover 2. Loosen bolts and nuts securing motor and sprocket assembly to the main frame (Fig, 18). 1 3.

7. Remove (2) capscrews, washers and nut, on left side of machine, securing slider bed to frame (Fig. 29). 1 2 Figure 26 1. Hopper mounting capscrews (Right side shown) 2 5. Pivot hopper rearward and lean against wall, ladder, etc. Do no allow hopper to rest against rear of machine as damage may result to brash or hydraulic couplers (Fig. NO TAG). 1 Figure 29 Important Make sure hopper is pivoted beyond center and/or secured to wall or post to prevent it from accidentally falling on work area (Fig.
Hydraulic System Diagnostics drainage during dis–assembly), it may be necessary to crack open the highest point hydraulic line near the brush motor, while slowly towing the unit, to purge air from the closed circuit. Flow Rates and Performance Checks – Since the Top Dresser 2500 uses ground driven hydraulics, it is necessary to tow the unit to do these performance tests.
Trouble Shooting • Difficulty in connecting or disconnecting control wires: – Wrong connector on tow vehicle. An additional harness may be acquired from your distributor. – On/off connections switched with brake wiring. • Topdresser hard to pull with tow vehicle: – Wheel motors (pumps) not turning. – Plumbing reversed. – Brake solenoid activated (check wiring). – Hydraulic oil hot. • Hydraulic leaks: – Fittings loose. – Oil filter loose. – Fitting missing o–ring. – Reservoir over filled.
