Reelmaster® 3100-D Traction Unit

Before starting the machine each day, perform the Each Use/Daily procedures listed in .

1. Ensure that all bystanders are away from the area of operation, and keep hands and feet away from the cutting units.

2. While sitting on the seat, the engine must not start with either the cutting unit switch engaged or the traction pedal engaged. Correct the problem if it is not operating properly.

3. While sitting on the seat, put the traction pedal in neutral, disengage the parking brake, and set the cutting unit switch in the OFF position. The engine should start. Rise from the seat and slowly press the traction pedal, and the engine should shut off in 1 to 3 seconds. Correct the problem if it is not operating properly.

Note: The machine is equipped with an interlock switch on the parking brake. The engine shuts off if you press the traction pedal with the parking brake engaged.

Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

The fuel tank capacity is approximately 28 L (7.5 US gallons).

Use summer-grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter-grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Using winter-grade fuel at lower temperatures provides a lower flash point and cold flow characteristics, which eases starting and reduces plugging of the fuel filter.

Using summer-grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter-grade fuel.

Biodiesel Ready

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

• The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

• The blended fuel composition should meet ASTM D975 or EN590.

• Painted surfaces may be damaged by biodiesel blends.

• Use B5 (biodiesel content of 5%) or lesser blends in cold weather.

• Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time.

• Fuel filter plugging may be expected for a time after converting to biodiesel blends.

• Contact a distributor for more information on biodiesel blended fuel.

1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

8. Before reaching the turnaround location, pull back the cutting-unit shift lever only long enough to raise the cutting units, and release the control lever.

   Important: Do not hold the cutting-unit shift lever back while turning.

9. Perform a tear-shaped turn to quickly line up for your next pass.

To achieve a consistent, high quality of cut and a uniform after-cut appearance, it is important that the reel speed be matched to the height of cut.

Important: If the reel speed is too slow, you may notice visible clip marks. If the reel speed is too fast, the cut may have a fuzzy appearance.

Reel Speed Selection Chart

1. Verify the height-of-cut setting on the cutting units. Use the column of the Reel Speed Selection Chart listing either 5-blade, 8-blade, or 11-blade reels, and find the height-of-cut listing nearest the actual height-of-cut setting. Look across the chart to find the reel-speed number that corresponds to that height of cut.

2. Lift the cover from the control arm (Figure 38).

   

   Figure 38

   Figure 39

   1. Reel speed control
   2. Backlap control

4. Assemble the cover onto the control arm.

5. Operate the machine for several days, then examine the cut to ensure the quality of cut. The reel speed knob may be set 1 position on either side of the reel-speed number indicated on the chart to account for differences in grass condition, grass length removed, and personal preference.

Wash the machine and grease it; refer to Washing the Machine and Greasing the Bearings And Bushings

• Use full-width ramps for loading the machine onto a trailer or truck.

• Tie the machine down securely.

In case of an emergency, the machine can be towed for a short distance; however, Toro does not recommend this as a standard procedure.

Important: Do not tow the machine faster than 3 to 4 km/h (2 to 3 mph) because it may damage the drive system. If the machine must be moved a considerable distance, transport it on a truck or trailer.

   Figure 44

The machine has grease fittings that must be lubricated regularly with No. 2 lithium grease. Lubricate the bearings and bushings daily when the operating conditions are extremely dusty and dirty. Dusty and dirty operating conditions could cause dirt to get into the bearings and bushings, resulting in accelerated wear. Lubricate the grease fittings immediately after every washing, regardless of the interval specified.

The grease fitting locations and quantities are as follows:

• Rear cutting unit pivot (Figure 45)

  

  Figure 45

• Front cutting unit pivot (Figure 46)

  Figure 56

Bearings rarely fail from defects in materials or workmanship. The most common reason for failure is moisture and contamination working its way past the protective seals. Bearings that are greased rely upon regular maintenance to purge harmful debris from the bearing area. Sealed bearings rely on an initial fill of special grease and a robust integral seal to keep contaminants and moisture out of the rolling elements.

The sealed bearings require no lubrication or short-term maintenance. This minimizes routine service required and reduces the potential of turf damage due to grease contamination. These sealed bearing packages will provide good performance and life under normal use, but you should periodically inspect the bearing condition and seal integrity to avoid downtime. Inspect the bearings seasonally and replace the them if they are damaged or worn. Bearings should operate smoothly with no detrimental characteristics such as high heat, noise, looseness, or indications of corrosion (rust).

Due to the operating conditions these bearing/seal packages are subject to (i.e., sand, turf chemicals, water, impacts, etc.) they are considered normal wear items. Bearings that fail due to causes other than defects in materials or workmanship are typically not covered under the warranty.

Note: Bearing life can be negatively affected by improper wash-down procedures. Do not wash down the machine when it is still hot and avoid directing high-pressure or high-volume spray at the bearings.

• Check the air cleaner body for damage which could cause an air leak. Replace it if it is damaged. Check the whole intake system for leaks, damage, or loose hose clamps.

• Service the air cleaner at the recommended service interval or earlier if engine performance suffers due to extremely dusty, dirty conditions. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.

• Ensure that the cover is seated correctly and seals with the air-cleaner body.

1. Release the latches that secure the air-cleaner cover to the air-cleaner body (Figure 57).

   

   Figure 57

   1. Air-cleaner cover
   2. Air-cleaner latch

2. Remove the cover from the air-cleaner body.

3. Before removing the filter, use low-pressure air—276 kPa (40 psi), clean and dry—to help remove large accumulations of debris packed between the outside of primary filter and the canister. Avoid using high-pressure air which could force dirt through the filter into the intake tract. This cleaning process prevents debris from migrating into the intake when you remove the primary filter.

4. Remove and replace the primary filter (Figure 58).

   Note: Cleaning the used element may damage the filter media.

   

   Figure 58

   1. Primary filter

5. Inspect the new filter for shipping damage and check the sealing end of the filter and the body. Do not use a damaged element.

6. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister. Do not apply pressure to the flexible center of the filter.

7. Clean the dirt ejection port located in the removable cover.

8. Remove the rubber outlet valve from the cover, clean the cavity, and replace the outlet valve.

9. Install the cover orienting the rubber outlet valve in a downward position—between approximately 5 o'clock to 7 o'clock when viewed from the end.

10. Secure the cover latches.

The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started.

The crankcase capacity is approximately 3.8 L (4.0 US qt) with the filter.

Use high-quality engine oil that meets the following specifications:

• API Classification Level Required: CH-4, CI-4 or higher.

• Preferred oil: SAE 15W-40 (above -17ºC (0ºF))

• Alternate oil: SAE 10W-30 or 5W-30 (all temperatures)

Note: Toro Premium Engine oil is available from a distributor in either 15W-40 or 10W-30 viscosity. See the parts catalog for part numbers.

Note: The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the Add mark on the dipstick, add oil to bring the oil level to the Full mark. Do not overfill. If the oil level is between the Full and Add marks, you do not need to add oil.

1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage the parking brake, and remove the key from the ignition switch.

2. Remove the dipstick (Figure 59) and wipe it with a clean rag.

   

   Figure 59

   1. Dipstick

3. Push the dipstick down into the dipstick tube and ensure that it is seated fully, then pull the dipstick out and check the oil level.

4. If the oil level is low, remove the oil-fill cap (Figure 60) and gradually add small quantities of oil, checking the level frequently, until the level reaches the Full mark on the dipstick.

   

   Figure 60

   1. Oil-fill cap

5. Install the oil-fill cap and close the hood.

   Important: Keep the engine-oil level between the upper and lower limits on the oil gauge. Engine failure may occur as a result of overfilling or underfilling the engine oil.

4. Tighten the pipe connector securely.

5. Repeat this procedure on the remaining nozzles.

The battery electrolyte level must be properly maintained and the top of the battery kept clean. If the machine is stored in a location where temperatures are extremely high, the battery will run down more rapidly than if the machine is stored in a location where temperatures are cool.

Maintain the cell level with distilled or demineralized water. Do not fill the cells above the bottom of the split ring inside each cell. Install the filler caps with the vents pointing to the rear (toward the fuel tank).

Keep the top of the battery clean by washing it periodically with a brush dipped in ammonia or bicarbonate of soda solution. Flush the top surface with water after cleaning. Do not remove the filler caps while cleaning.

The battery cables must be tight on the terminals to provide good electrical contact.

If corrosion occurs at the terminals, disconnect the cables, negative (–) cable first, and scrape the clamps and terminals separately. Connect the cables, positive (+) cable first, and coat the terminals with petroleum jelly.
