Before Operation

Before Operation Safety

  • Do Not modify the Spreader Accessory.

  • Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use on machines approved by Exmark.

  • Wear appropriate personal protective equipment such as safety glasses, substantial slip-resistant footwear, and hearing protection. Tie back long hair and avoid loose clothing and loose jewelry which may get tangled in moving parts.

    Caution

    The machine that the spreader accessory attaches to produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.

    Wear hearing protection when operating this machine.

  • Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects which can be thrown by the machine and may cause personal injury to the operator or bystanders.

Pre-Start

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Ensure that the hopper and its components are in good condition, properly attached, and latched.

Operating Instructions

During Operation Safety

General Safety

The operator must use their full attention when operating the machine. Do Not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

Caution

Machine can spin very rapidly by positioning one lever too much ahead of the other. Operator may lose control of the machine, which may cause damage to the machine or injury.

  • Use caution when making turns.

  • Slow the machine down before making sharp turns.

Warning

Hands, feet, hair, clothing, or accessories can become entangled in rotating parts. Contact with the rotating parts can cause traumatic amputation or severe lacerations.

  • Do Not operate the machine without guards, shields, and safety devices in place and working properly.

  • Keep hands, feet, hair, jewelry, or clothing away from rotating parts.

  • Operate only in daylight or good artificial light.

  • Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, Do Not operate the machine; seek shelter.

  • Be aware of weather conditions and check that spray nozzles, patterns, and volume are suitable.

  • Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine or cause the operator to lose their balance or footing.

  • Never operate the machine with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition.

  • Keep clear of the discharge area at all times.

  • Stop spreading when making tight turns to minimize uneven distribution pattern and application rate.

  • Reduce the weight of the load when operating on hills and rough terrain to avoid tipping or overturning of the machine.

  • Material loads can shift. This shifting happens most often while turning, going up or down hills, suddenly changing speeds, or while driving over rough surfaces. Shifting loads can cause the machine to tip over.

  • When operating with a heavy load, reduce your speed and allow for sufficient stopping distance. Use extra caution on slopes.

  • Reduce speed and load when operating on rough terrain, uneven ground, and near curbs, holes, and other sudden changes in terrain. Loads may shift, causing the spreader to become unstable.

    Warning

    Sudden changes in terrain may cause abrupt steering wheel movement, possibly resulting in hand and arm injuries.

    Reduce speed when operating on rough terrain or near curbs.

  • Heavy loads affect stability. Reduce the weight of the load and your speed when operating on hills.

  • Stopping distance may vary depending on the spreader load.

Operating the Spreader Accessory

The spreader accessory is designed to disperse grass seed.

Before Operating the Spreader

Make sure the spreader has been calibrated for the correct application rate of the grass seed to be spread before starting (see Calculating the Application Rate section).

Filling the Spreader Hopper

Important: Verify that the proper application rate has been set prior to filling the hopper.

  1. Stop the unit on a level surface, move motion control lever to the neutral position, stop the engine, and set the parking brake.

  2. Ensure that the spreader gate is closed.

  3. Remove the cover from the hopper, add the grass seed to be spread, and replace the cover.

    Note: Do Not overload the hopper; the maximum weight capacity of the hopper is 80 lb (36 kg).

Calculating the Application Rate

  1. Determine the pounds per 1,000 ft2 (93 m2) of product to be applied.

  2. Determine the calibration course:

    1. Determine the amount of product to be spread per 1,000 ft2 (93 m2). Use the recommended rate from the Spreading Chart section or the product manufacturer’s label as a guide.

    2. Determine a course length by dividing 1,000 ft2 (93 m2) by the effective spread width.

      For example, if the effective width is 6 feet (1.8 meters), then the calibration course length equals 167 ft (51 m).

      Course Length

       1,000 ft2 (93 m2)=167 ft (51 m)
        6 ft (1.8 m)
    3. The calibration course is 6 ft (1.8 m) by 167 ft (51 m).

    4. Measure and visibly mark the course length. Make sure to allow ample distance before the starting marker to ensure the spreader is at full speed when crossing the first mark of the course.

  3. Set the appropriate gate setting (reference the Spreading Chart section as a starting point).

  4. Add grass seed to the hopper (for example, 25 lb (11.3 kg) was added).

  5. Drive the spreader over the calibration course while applying the grass seed.

  6. Empty the remaining grass seed of the hopper into a clean bucket.

  7. Weigh the bucket containing the grass seed and record the weight. Pour the contents back into the hopper and then weigh the empty bucket. Subtract these two amounts to determine the amount of grass seed remaining in the hopper (for example, 20 pounds (9 kg) remains.)

  8. Subtract the amount remaining in the hopper (step 7) from the amount originally added (step 4); the result is the amount applied to the course.

    Amount Applied

     25 lb (11.3 kg) – 20 lb (9 kg)=5 lb (2.3 kg)

    For this example, 5 lb (2.3 kg) was applied to 1,000 ft2 (93 m2).

  9. If necessary, adjust the rate lever to achieve the recommended amount to be applied and repeat the procedure. Once the correct application rate is achieved, repeat this procedure an additional time to verify the results.

Spreading

Spreading Tips:

  • To ensure uniform application, be sure to overlap the grass seed distribution. The highest amount of seed will dispense from the front of the hopper and less from each side. Adjust the distribution pattern to achieve desired results.

  • Watch for changes in the distribution pattern; unequal distribution may lead to striping.

    g207791
  1. Start the engine and place the throttle midway between the “SLOW” and “FAST” positions.

  2. Turn on the impeller speed control.

  3. Set the impeller speed to the appropriate setting.

  4. Move the throttle to the “FAST” position and drive forward.

  5. Open the hopper gate and begin spreading.

    g207728
  6. Evaluate the spread pattern. If adjustments are needed see the Spreader Pattern Adjustment section.

  7. When finished spreading, close the hopper gate.

Spreader Pattern Adjustment

If the spread pattern is skewed or dispensing too light/heavy to one side (see Figure 19 ), adjust the gate as follows:

g025543

Note: Do Not adjust the ramps to split product flow. Use only the front or rear ramp positions as shown.

  1. Unlock the spreader pattern control knob by turning it counterclockwise 90 degrees.

    g207877

    To adjust when the grass seed pattern is heavy:

    • to the left side, slightly pull the control handle rearward.

    • to the right side, slightly push the control handle forward.

  2. Lock the spreader pattern control by turning the control knob clockwise 90 degrees.

Operating Tips

Over Seeding

Important: Do Not put down more seed than recommended by the seed company. Over seeding can cause the grass to be too thick and cause it to be susceptible to fungus.

Note: The machine will seed at the same rate going both forward and rearward.

Note: If there is excessive thatch, it may be necessary to remove the thatch prior to seeding.
