2. Connect the Outcross wire harness connector to the brake controller connector.

   Refer to the Outcross traction unit Operator’s Manual for additional mounting and operating instructions.

Mount the brake controller to the dash or the fender of the tractor with the 2 bolts (#10 x 7/8 inch) and nuts (#10).

Note: Lay out the harness on the traction unit to determine the mounting locations of the harness components. Use cable ties to bundle surplus cable lengths. Also, use the wire splices when altering the harness length (shortened or lengthened). Heat the shrink the connectors until they are tight to the wires.

Important: If you add wire to the harness, ensure to use the proper gauge wire.

1. Mount the socket bracket to the rear of the traction unit with 2 bolts (5/16 x 1 inch) and nuts.

2. Route the wire harness connector through the hole to the socket.

   If the connector does not go through the hole, slide the boot down the harness.

3. Bolt the wire harness, with the socket connector, to the rear of the socket bracket with 2 bolts (5/16 x 1 inch) and nuts.

4. Route the harness along the traction unit.

5. Use the hose clamp to secure the foot controller to the pad on the brake pedal.

6. Connect the harness to the components (Figure 9) as follows:

   1. Plug the shorter wire from the harness into the foot controller wire connector.

   2. Connect the longer wire from the harness to the brake controller wire connector.

   3. Select one of the following procedures when connecting the ring terminal wire (with the fuse) to a positive electrical source:

      • To have the brake controller powered only when the traction unit is powered on, attach the ring terminal wire, with the fuse, to an open auxiliary-power source that has a rating of 15A or more.

        Use a 10A fuse for a 2 wheel brake system and a 15A fuse for a 4 wheel brake system.

        Note: You may need to remove the ring terminal and install a different terminal type to match the auxiliary power source connection.

      • To have the brake controller always powered, attach the ring terminal wire, with the fuse, to the positive battery terminal.

        Note: If you store the traction unit for an extended period, remove the fuse from the brake controller wire harness or disconnect the wire harness from the brake controller. This prevents the battery from discharging

   4. Connect the other ring terminal wire, without the fuse, to the negative (-) battery terminal.

Perform the following steps when towing the machine:

• Before operating the machine, stow the jack and rear jack leg.

• Do not allow the hydraulic hoses, the power cable, and the pendant cables to drag on the ground during operation. Avoid locations where they could become pinched or cut.

• When making sharp turns, the hydraulic hoses may contact the traction unit wheels. Avoid making sharp turns, if necessary, use a bungee cord (a rubber strap with hooks on both ends) to pull back the hoses and cables toward the center.

The load control compensates for trailer load variations by limiting the maximum torque output of the brakes by adding dropping resistance in the electrical control line. Consider the following operating conditions:

• When towing a trailer loaded to brake rated capacity, set the brake control for maximum braking.

• When pulling an empty or partially loaded trailer, set the brake control between maximum and minimum braking at a position, just before the point at which the machine tire skids when actuating the hand control fully on.

Failure to install and use the electric brake control results in excessive brake torque when stopping a machine loaded to less than brake capacity.

When finished working with the machine, always press the E-STOP button (Figure 29) to disable the electrical system. When beginning work with the machine, you must pull the E-STOP button back out before turning on the handheld remote.

Use the following procedures to set and operate the machine floor and option (such as the twin spinner or other attachment) as follows:

• Setting and operating the floor alone

• Setting and operating the option alone

• Setting and operating both floor and option together

Important: Do not carry passengers in the hopper.

Important: Do not carry loads that exceed the load limits of the machine, or the tow vehicle; refer to Specifications.

Important: The stability of loads can vary—for example, high loads have a higher center of gravity. Reduce the maximum load limits to ensure better stability, if necessary.

1. Connect the machine to the tow vehicle.

2. Load the hopper with material.

   • Load the machine from the top or from the rear.

   • For most materials, such as sand or gravel, you can use a front-end bucket loader. For materials such as landscaping timbers or fertilizer bags, load from the rear by placing the material on the conveyor belt and setting the hydraulics in the load position.

   • You may need to remove the rear gate for easier access.

   • If sacks of material are used, empty the sacks into the loader’s bucket before loading the material into the hopper. To ensure stability, distribute the load evenly, front to back and side to side.

   Important: Do not put large or heavy objects into the hopper. Material that is larger than the rear gate opening may damage the belt and rear gate assembly. Also ensure that the load has a uniform texture. The machine can unpredictably throw small rocks in the sand.

   To avoid causing the machine to tip over (see safety decals in this manual):

   • Carefully monitor the height and weight of the load. Higher and heavier loads can increase the risk of tipping.

   • Distribute the load evenly, front to back and side to side.

   • Be careful when turning and avoid an unsafe maneuver.

• Do not stand behind the machine when unloading.

• Do not unload the machine while it is on a slope.

1. Shut off the engine of the traction unit.

2. On SH models, using the control levers, turn on the option and the conveyor belt (unload position).

3. For both the SH and EH models, adjust the settings, spread pattern, and flow rate.

   Note: You may have to experiment until you get the desired flow and spread depth. Other variables include ground speed and the type of material. Different materials vary in particle size, which can vary the spread pattern.

   Always test new materials by spreading them in an open area away from people.

4. Start the engine of the traction unit and turn on the traction unit hydraulics.

5. On the SH model turn on the on/off pendant switch to start spreading. On the EH model turn on the option then the conveyor belt with the handheld remote.

6. On the SH model turn off the on/off pendant switch to stop spreading—the option attachment continues to operate. On the EH model turn off the conveyor belt and then the attachment.

7. For EH models you can use the ALL START function in place of the OPTION START and BELT START functions as a single operation start feature. The attachment will start first, followed by the belt.

8. When the machine is empty, turn off the hydraulics before transporting the machine.

   Note: When driving over uneven terrain, raise the machine to the maximum safe traveling range. This provides more ground clearance for the optional attachment.

   Warning

   The optional attachment may be able throw material at high speeds up to 12 m (40 ft), and injure bystanders.

   Watch for people and other objects while spreading.

   Important: While traveling but not spreading, raise the machine to the maximum safe traveling distance, and turn off the option attachments.

1. Park the machine on dry, level ground; engage the parking brake on the traction unit; shut off the engine and remove the key.

2. Chock front and back of the tires of the machine.

3. Relieve the pressure from the hydraulic system.

4. Disconnect the 2 hydraulic hoses and the 7-pin coiled power cable from the traction unit; refer to Figure 21 in Connecting the Machine to the Traction Unit.

   Adjust the brake shoes out until the pressure of the linings against the drum makes the wheel difficult to turn.

   

   Figure 51

   1. Screwdriver

5. Rotate the star wheel in the opposite direction until the wheel turns freely with a slight drag on the lining.

6. Install the adjusting hole cover.

7. Repeat steps 2 through each brake.

When a brake shoe becomes worn, replace both shoes on each brake, and both brakes on the same axle. This ensures that the brakes remain balanced.

Replace the brake linings under the following conditions:

• They are worn to 1/16 inch (1.6 mm) or less remaining thickness.

• They are contaminated with grease or oil.

• They are abnormally scored or gouged.

  Note: Hairline heat cracks are normal in the brake linings.

• Change magnets and shoes when they become worn or scored.

• Clean the backing plate, magnet arm, magnet, and brake shoes with an automotive brake cleaner.

• Ensure that all parts removed are replaced in the same brake and drum assembly that they were removed from.

• Inspect the magnet arm for any loose or worn parts.

• Check the shoe return springs, the hold down springs, and the adjuster springs for stretch or deformation and replace them if required.

  Caution

  Brake dust can be hazardous to your health if inhaled; take the following precautions when servicing brakes:

  • Do not create or breathe dust.

  • Do not machine, file, or grind the brake linings.

  • Do not use compressed air or dry brushing for cleaning.

Before reassembling the electric brakes, apply a light film of anti-seize compound, or grease such as Lubriplate™ on the following:

• Brake anchor pin

• Actuating arm bushing and pin

• Areas on the backing plate that are in contact with the brake shoes and magnet lever arm

• Actuating block on the actuating arm

Important: Do not allow grease to contact the brake linings, drums, or magnets.

The electromagnets of the brakes are designed to provide the proper input force and friction.

Inspect the magnets regularly, and replace if they become unevenly worn. Use a tool with a straight edge to check wear.

Even if the wear is normal, replace the magnets if any part of the magnet coil is visible through the friction material on the magnet face. Replace the magnets in pairs (both sides of an axle).

When replacing the magnets, also resurface the drum armature surface.

Alternate fluids: If the Toro fluid is not available, other petroleum-based Universal Tractor Hydraulic Fluids (UTHF) may be used provided its specifications fall within the listed range for all the following material properties and it meets industry standards. We do not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product.

Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.

1. Check the hydraulic system for oil leaks.

   If you find a leak, tighten the fitting, or replace or repair the damaged part.

2. Check the hydraulic hoses for wear or damage.

   Replace worn or damaged hoses

3. Check the hydraulic-fluid level of the traction unit.

   Add hydraulic-fluid level to the reservoir if needed; refer to the Operator’s Manual for your traction unit.

• Check that the quick attach brackets are secure and that the safety clips are installed.

  Replace any missing safety clips.

• Check that the optional attachment is securely clamped and does not move or slide out.

  Adjust clamps if required.

• Check the paddles on the Twin Spinner disks for wear.

  Replace the paddles when they wear thin.

• Check the Twin Spinner housing for signs of cracking or corrosion.

• Check that the conveyor belt tracks straight on the rollers and it does not slip.

  Adjust the conveyor belt tracking if required; refer to Adjusting the Conveyor Belt Tracking.

• Check that the idler rollers between the front and rear rollers are not bent or seized.

  Replace or repair worn or damaged idler rollers if required.

If the conveyor belt is not centered and tracks to one side, it needs to be adjusted (Figure 52). The best time to do this is between loads during operation.

1. Go to the rear of the machine and determine which side of the belt is touching.

2. Go to the front on the same side, loosen the locking nut, and tighten the adjuster nut by one quarter turn.

3. Tighten both locking nuts before running the machine.

4. Load the machine with material and run the load through until empty. Repeat multiple times.

5. Stop the belt and go to the rear of the machine to observe the results.

   You may need to repeat the above steps several times until the belt begins to move and track properly.

   Note: The belt may move slightly depending on the type of load and its position. If the belt is not touching the side rails, you do not need to track the belt.

   Important: Do not adjust the rear drive roller of the conveyor belt. It is set to factory specifications. Contact your authorized Toro distributor it needs an adjustment.

Check and adjust the belt tension frequently (Figure 52). All rubber conveyor belts stretch, especially when they are new or have not been used for a while.

1. Park the machine on level ground with the rear gate and feed gate at least 6.25 mm (1/4 inch) off the floor (depending on the material).

2. Fully load the machine with sand that you expect the machine to use.

3. Remove the black front covers on either side of the machine.

4. Using two wrenches, hold the end of the tensioner rod stationary, while loosening the locking nut closest to the end of the rod.

5. Move the locking nut back 2 to 5 cm (1 to 2 inches).

   Warning

   Operating the conveyor belt with the guards and covers removed can cause serious injury.

   Use extreme caution around moving parts with safety guards removed.

6. Turn on the conveyor belt.

7. If belt slips, tighten the tension bolts evenly (with machine off) half a turn and check if the belt slips again. Continue until the belt moves without any slippage.

8. Give both tensioning bolts another half turn. At this point you should have proper tension.

9. To verify belt tension, look underneath the machine at the chassis cross member. The middle of the belt should just clear the chassis cross member when the machine is in the down position. If the middle of the belt is touching the cross member, tighten both tensioning bolts another quarter of a turn.

   Important: Be patient. Do not over-tension the belt.

   Important: Do not use air tools on the belt tensioning bolts.

Read these instructions before removing the belt. If the belt is destroyed, use a knife to cut the belt in an undamaged area. If you intend to make a warranty claim, the belt supplier must inspect the belt to evaluate the damage and make recommendations for a replacement.

If the conveyor drive chain is loose, it needs to be tightened (Figure 56).

1. Shut off the engine of the traction unit and engage the parking brake.

2. Remove the rear conveyor drive guard.

3. Loosen the bolt that goes through the tensioner sprocket.

4. Tighten the positive locking screw using moderate force.

5. Tighten the tensioner sprocket bolt.

   Important: Do not over tension the chain. Leave just enough tension to take up the extra slack.

6. Check that the chain is sufficiently lubricated, and the sprockets are secure to the shafts.

7. Replace the rear conveyor drive guard.
