  • Stop the machine, shut off the engine, wait for all moving parts to stop, and inspect the machine after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

  • Always maintain proper traction unit tire pressure.

  • Reduce speed on rough surfaces.

  • For all PTO shaft steel parts (tubes, bearings, joints, etc.) disassembly or repairs, it is highly advisable to contact your authorized Toro distributor. Removal of components for repairs and reassembly may damage some parts if not performed with special tools by trained technicians.

  • The PTO shaft must not be used without the guards supplied.

Dumping Safety

  • Moving the rear door and dumping debris can cause serious injury. Stay clear of the machine while it is backing up or dumping.

  • Keep bystanders away from the machine when operating to dump debris or when opening and closing the rear door.

  • Under rare circumstances, wet, compressed grass clippings may generate heat. Always empty the machine before storing it.

  • To avoid the risk of electrical shock, dump the machine only in areas that are clear of overhead wires and other obstructions.

  • Never dump the machine on a slope; always dump the machine on level ground.

Slope Safety

  • Review the traction unit specifications to ensure that you do not exceed its slope capabilities.

  • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.

  • Evaluate the site conditions to determine if the slope is safe for machine operation including surveying the site. Always use common sense and good judgment when performing this survey.

  • Review the slope instructions listed below for operating the machine on slopes and review the conditions to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.

  • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.

  • Do not operate a machine under any conditions where traction, steering, or stability is in question.

  • Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.

  • Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

  • Use extreme caution when operating the machine near drop offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.

Operating the Traction Unit Hydraulics

All hydraulic machine functions are controlled by the hydraulic valve that is located at the front of the machine. The PTO must be running while the machine is in use. This is what creates the continuous fluid flow throughout the machine.

Important: Never move a hydraulic lever rapidly between the up and down positions. Forcing a hydraulic motor to reverse direction instantly may severely damage it. If any part of the machine becomes plugged or material does not want to flow, shut the machine off completely and manually remove the blockage.

Note: You can adjust the hydraulic control console for comfort by loosening the lever on the frame behind the controls, adjusting the control console fore or aft, and tightening the lever.

Operating the Machine

  1. Start the traction unit and run it at a low rpm.

    Checking the Hydraulic Fluid Level

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the hydraulic fluid level.
    		•

    1. Operate the machine so that the fluid is warm, park the machine on a level surface, and shut off the engine.

    2. Check the level of the fluid by viewing the sight gauge (Figure 12).

      You should see the fluid level is in the middle of the sight gauge.

      1. Sight gauge
      2. Hydraulic reservoir cap

    3. If the fluid level is below the middle of the gauge, remove the cap from the hydraulic fluid reservoir and slowly add the specified hydraulic fluid until the level reaches the middle (maximum) of the sight gauge; refer to Hydraulic Fluid Specifications.

      Important: Do not over fill the reservoir; if you exceed the max fill line of the sight gauge you must remove the excess fluid; refer to Changing the Hydraulic Fluid.

      Important: To prevent hydraulic system contamination, clean the top of the hydraulic-fluid containers opening it. Ensure that the pour spout and the funnel are clean.

    4. Install the reservoir cap.

    Changing the Hydraulic Fluid

    Maintenance Service IntervalMaintenance Procedure
    Every 800 hours
  • If you are not using the recommended hydraulic fluid or have ever filled the reservoir with an alternative fluid, change the hydraulic fluid.
    • Every 2,000 hours
  • If you are using the recommended hydraulic fluid, change the hydraulic fluid and filter.
    		•

    Reservoir capacity: approximately 38 L (10 US gallons)

    Important: If the fluid becomes contaminated, contact an authorized the manufacturer distributor. Contaminated fluid looks milky or black when compared to clean fluid.

    1. Turn the engine off.

    2. Disconnect the small hydraulic hose (case drain) from the bottom of the reservoir and let the hydraulic fluid flow into a drain pan.

      Note: Install and tighten the hose when the hydraulic fluid stops draining.

    3. Fill the reservoir with approximately 38 L (10 US gallons) of the specified hydraulic fluid; refer to Hydraulic Fluid Specifications.

      Important: Use only the hydraulic fluids specified. Other fluids could damage the system. To prevent over filling, do not fill if the fluid is cold. Do not over fill the reservoir with hydraulic fluid.

    4. Install the reservoir cap.

    5. Start the traction unit engine, use all the hydraulic controls to distribute the hydraulic fluid throughout the system, and check for leaks.

    6. Shut off the engine

    7. With the fluid warm, look into the sight gauge.

      Note: If the hydraulic fluid level is low, add enough fluid to raise the level to the middle (maximum) of the sight gauge.

    Replacing the Hydraulic Filter

    Maintenance Service IntervalMaintenance Procedure
    Every 800 hours
  • If you are not using the recommended hydraulic fluid or have ever filled the reservoir with an alternative fluid, change the hydraulic filter.
    		•
    Every 1,000 hours
  • If you are using the recommended hydraulic fluid, replace the hydraulic filter.
    		•

    Use only the the manufacturer replacement filter in the hydraulic system; refer to the Parts Catalog.

    Important: Use of any other filter may void the warranty on some components.

    1. Turn the traction unit engine off and remove the key from the ignition.

    2. Clean the area around the filter mounting area.

    3. Place a drain pan under the filter and remove the filter (Figure 13).

      1. Hydraulic filter

    4. Lubricate the new filter gasket and fill the filter with hydraulic fluid.

    5. Ensure that the filter mounting area is clean.

    6. Screw the filter on until the gasket contacts the mounting plate, then tighten the filter one–half turn.

    7. Start the traction unit engine and operate the hydraulic controls to purge air from the system.

    8. Shut off the engine and check the fluid level and for any leaks.

    Adjusting the Impeller Belt

    Maintenance Service IntervalMaintenance Procedure
    After the first 20 hours
  • Check/adjust the impeller belt tension.
    		•
    Monthly
  • Check/adjust the impeller belt tension.
    		•

    Make sure that the belt is properly tensioned to ensure proper operation of the machine and prevent unnecessary wear.

    1. Loosen the bolts and nuts securing the drive shield to the impeller housing (Figure 14) and remove the shield.

      1. Drive shield

      Note: You do not need to disconnect the drive shaft to adjust the belt tension.

    2. On back side of the frame, loosen the bolt securing the belt tensioner to the frame (Figure 14).

    3. Remove the bolt and nut securing the tensioner guide to the drive mount to release the belt tension (Figure 15).

      2. Bolt and nut
      3. Bolt (back of frame)

    4. Using a large wrench, rotate the tensioner clockwise until the decal is aligned with 15° on the tensioner tube.

      Important: Align the tensioner as close to 15° as possible without going under.Rotating the tensioner too far over 15° can over-tension the belt, rotating it under 15° will leave the belt too loose; both can damage the machine.

    5. Insert the bolt into the aligned guide holes and secure it with the nut.

      Important: If the holes are not exactly aligned, rotate the guide to the next higher hole until it is aligned.

    6. Tighten the bolt at the back side of the frame to lock the tensioner.

    7. Install the drive shield to the impeller housing with the bolts and nuts removed previously.

    Storage

    1. Park the machine on a level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine.

    2. Thoroughly clean the machine. The impeller housing should be free of dirt, leaves, and debris.

    3. Check the tire pressure; refer to Checking the Tire Air Pressure.

    4. Tighten all fasteners as necessary.

    5. Grease or oil all grease fittings and pivot points. Wipe up any excess lubricant.

    6. Place a light coat of grease on the splines of the PTO shaft.

    7. Lightly sand and use touch-up paint on painted areas that are scratched, chipped, or rusted. Repair any dents in the metal body.
