Safety – With a smaller tow vehicle, you may need to reduce the payload to 2.6 cubic yards (2 cubic meters) of material for spreading in difficult terrain. Another option is to tow a fully loaded machine to a spot near the job and then load smaller machines from the machine to complete the job. Improper use or maintenance by the operator or owner can result in injury.
• Operator should remain seated whenever the tow vehicle is in motion. • You can load the machine from the top or the rear. When loading from the rear, raise or remove the rear gate. • Ensure that the machine is connected to the tow vehicle before loading. • Do not carry loads that exceed the load limits of the machine or the tow vehicle. • 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.
• Do not disconnect the machine from the tow vehicle on hills, or without engaging the front jack and rear jack leg. • Do not travel with the machine in the fully raised position. This increases the risk of tipping over. • Before operating the machine, raise the front jack and rear jack leg. Remove the jack from the jack leg and store it on the tongue during operation • Maintain safe control of the machine. Do not attempt abrupt maneuvers or other unsafe actions, especially on hills or uneven ground.

Both the FLOOR and the OPTION must be running before the ALL STORE speed setting can be stored in memory.
Unloading Material WARNING Do not stand behind the machine while unloading Bulk Unloading 1. Back the machine into the location where you want the material deposited. 2. Release the rear gate latches and turn on the conveyor belt. 3. If desired, raise the rear of the machine. This unloads material at a different angle, and allows quick unloading of the entire load. Figure 28 Controlled Unloading 1. 5 inch (12.5 cm) maximum 2. Feed gate opening 1. Close the rear gate latches. 2.
Twin Spinner Operation 6. Ensure that the twin spinner is centered between the brackets. Then re install the lock rings over the lock pins and push down on the clamp handles Installing the Twin Spinner The MH-400 comes equipped with a pair of quick attach mounting clamps. Use these clamps to mount the twin spinner to the MH-400. Note: If the clamp assembly is too loose and the twin spinner slides within the clamps, turn the lock rings into the clamps a few turns until the twin spinner is secure. 1.
Connecting the Hydraulic Hoses • Hold the male connector firmly in place and release the outer sleeve of the female connector. WARNING • Ensure that the connectors are pushed all the way in and are securely locked in place. Ensure that the tow vehicle is turned off before making the hydraulic connections, to prevent the cross conveyor/swivel from accidentally turning on.
Adjusting the Hopper Gate and Belt Speed MH-400 SH models Rotate the crank to adjust the gate until the arrow aligns with the center of the YELLOW section which is number 3 (Figure 34). The adjustment of the spread density will be controlled through the main hopper gate opening or through the tow vehicle speed. Figure 32 1. Handle 2. Slide the twin spinner, fore and aft, until the arrows match the desired color. 3. Tighten the handles. Note: For this example we will select YELLOW.
Note: When driving over uneven terrain, raise the machine to the maximum safe traveling range. This provides more ground clearance for the Twin Spinner. WARNING Watch for people and other objects while spreading. The Twin Spinner can throw material at high speeds up to 40 feet (12 m). Important: While traveling but not spreading, raise the machine to the maximum safe traveling distance, and turn off the Twin Spinner (Figure 35). Figure 35 1. Hydraulic controls Fine Tuning the Twin Spinner 3. Cylinder 1.
Cross Conveyor/Swivel Operation 2. Ensure that the cross conveyor/swivel is centered between the mounting brackets and that the motor extends out the same side as the control handles on the MH-400. Installing the Cross Conveyor/Swivel 3. Remove the safety latch clips from the clamp handles (Figure 37).
Connect the hydraulic hoses to the option control valve on the MH-400 as follows (Figure 38): CAUTION Ensure that you reinstall the safety latch clips into the clamps. Otherwise, the clamps may open during operation. • Pull back (or push forward) on the outer sleeve of the female connector and insert the male connector. • Hold the male connector firmly in place and release the outer sleeve of the female connector.
Operating the Cross Conveyor 1. Remove the safety pins from both option attachment clamps on the swivel kit. Extending and Retracting the Cross Conveyor 2. Loosen the option attachment clamp brackets 3. Slide the conveyor to the center or side. Always operate the cross conveyor (Figure 39) separately from the main conveyor belt. 4. Re-tighten the clamp brackets. 5. Re-install the safety pins. CAUTION 6. On SH models adjust the speed of the cross conveyor with the hydraulic lever on the right.
Operating the Swivel Kit To direct the flow of material from the cross conveyor in any direction, pull up the spring-loaded locking pin on the swivel kit into the unlock or open position. This allows you to manually move the cross conveyor freely from side to side on the swivel bearing (Figure 39). To keep the cross conveyor in a fixed position, release the spring-loaded locking pin into one of the five locking positions on the swivel kit.
Maintenance 2. Pump grease into the bearing or bushing. 3. Wipe up excess grease. Premaintenance Procedures The bearing and bushing lubrication points are as follows: WARNING Disconnect all power sources to the machine before doing maintenance work. WARNING Install the hydraulic cylinder supports before doing any maintenance work under the hopper (Figure 41). Figure 42 Figure 41 Figure 43 1.
Rear Gate • Check that the rear gate closes and latches securely. • Check that the adjustable section of the rear gate opens and closes without sticking. Hitch, Jack, and Rear Jack Leg • Check that the hitch pin and jacks are not damaged, and the safety pins are in place. (Replace missing or damaged safety pins.) • Check that the hitch connections are not loose. (If so, install a spacer between the hitch connections.) • Safely stow all jacks in the up position before traveling.
Electric Brakes 7. Repair the damaged tire. 8. Re install the tire onto the machine by reversing the above steps. • Once a month, conduct a simple visual inspection of your brake shoes and linings. Note: Ensure that the wheel is centered on the hub and all six wheel bolts are tight. Torque in a crossover pattern to 100 ft-lb (13.8 kg-m). • Inspect and service your electric brakes once a year.
Important: Do not adjust the belt’s rear drive roller. It is set to factory specifications. Contact your authorized Toro distributor if adjustment is required. WARNING 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 recheck. 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.
22. Secure the cartridge by using straps from a lifting device on each of the four corners. 8. Go to the right front corner and remove the locking collar that holds the pillow block bearing on the shaft. Do this by backing off the set screws and turning the locking collar counterclockwise. Using a hammer and punch, tap the locking collar counterclockwise until it releases from the shaft. 9. Repeat this step for the left front corner. 10.
Note: Before sliding the rear drive roller back up through the slot and into place, ensure that you have already installed the four bolts (from the inside facing out) for connecting the pillow block bearings. Otherwise, you will have to remove the drive roller to gain enough clearance to install these bolts. When installing the rear drive roller, ensure that the shaft connecting to the motor is on the left side. It has a keyhole cut into it for securing the drive sprocket.
• 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.
