GR7000C GOLF GREENS ROLLER - Operation, Maintenance & Parts Manual
CORRECT DAMPENER STRUT OPERATION
• When the roller is in the trailing position and the front of the roller resting on the ground, carefully
hold the drawbar assembly, release the locking catch. With a rm grip begin to raise the drawbar,
when it has travelled sufciently the dampener strut will take over & prevent the trailer arms rapidly
rotating on it’s axle, allowing the roller to lower to the surface. This prevents the operator from being
injured. When the roller is resting on the ground push the trailer backwards gently, (do not use
excessive force) until the trailer arms will travel no further. The dampener strut is designed to hold
the trailer back behind the operator and the wheels off the ground.
REPLACE ENGINE OIL
• A tag is placed on the engine’s On/Off switch indicating you must ll the machine with oil prior to
operation. Low oil level will cause engine to stop on steep hills, the engine cut off safety switch is
designed this way to protect the engine from damage if low in oil.
• The oil in the engine upon delivery (if not pre-delivered) is to prevent the inside of the engine from
corroding, replace it with the correct engine oil, as per the manufacturers specications.
REPLACE TRANSMISSION OIL
• Ensure oil in transmission is hot prior to draining the oil.
• Remove drain plug from bottom of transmission using a socket and extension.
• Protect rubber coated drive roller from the draining oil. Oil left in contact with the rubber could
damage it’s surface.
• When oil has fully drained, replace plug and ll with recommended oil only - Refer to maintenance
schedule on pg. 13
• Fill through the upper plug on top of the transmission ensuring no contaminants enter the
transmission. (If this occurs rapid deterioration will occur and warranty will not apply).
• When transmission is full, leave the plug out and ll the plastic expansion cup with 3/8” of the
same oil. Allow the oil to gravity feed into the transmission until the oil overows from the plug hole,
expelling trapped air. Replace cap and tighten.
OPERATION AND MAINTENANCE

9
rollers
GR7000C GOLF GREENS ROLLER - Operation, Maintenance & Parts Manual
• It is necessary to ensure there is a minimum of 3/8” oil in the plastic expansion cup when in
the cold state. Do not over ll the cup as it is an expansion chamber to collect the oil from the
transmission when operating at high temperatures. Check oil level after rolling 3-4 greens, then
later when it has cooled off.
IMPORTANT: When the transmission is cold always ensure the minimum amount of oil is present
in the cup, as indicated by the minimum oil mark on the plastic cup. if the cup is dry of oil the
transmission will cavitate, overheat and lose drive ability.
LUBRICATE
• There is a grease nipple or zirk located on the smoothing head centre ball joint swivel. Apply
grease to lubricate tting.
• Grease drive roller bearings, sparingly.
• LubricateTransmission yoke slides, where the strut connects to the yoke on both sides.
• Rod ends.

GR7000C GOLF GREENS ROLLER - Operation, Maintenance & Parts Manual
PRE-OPERATION CHECKS
• Check engine as per Honda / Kohler manual.
• Ensure steering joystick has no looseness.
• Ensure that the trailer bar locking catch mechanism is securely locked to the main frame bolt when
in the towing position.
• Grease smoothing roller head centre ball-joint swivel lightly. Replace cap.
• Oil rod ends sparingly.
• Check all bearing races for correct function.
• Check for oil leaks - rectify before using machine.
STANDARD OPERATION PROCEDURES
• Check the position of the transmission neutral lever, (attached to the transmission bracket). Ensure
lever is in the upright position. If this lever is in the forward position, the transmission is in neutral
& the roller will not operate.
• Inspect and check that the roller is serviceable prior to departing from workshop.
• Use a suitable towing vehicle to move roller from green to green.
• Do not speed when towing roller or travel across rough terrain at excessive speeds. If you do,
damage may occur to the trailer or rubber coated drive roller. Maximum recommended speed
would be equal to a motorized golf buggy. Approximately 4mph / 7kph.
• When approaching the green do not tow roller onto the green to set up; put the roller on the fringe
of the green. Put trailer in the up position, start up the roller and drive it onto the green.
• Carefully select the direction you roll the greens, roll with the undulations not across them; take
care to ensure there are no crease lines produced on the surface.
• It is recommended that you place the smoothing head rollers on the high side of the green when
rolling. This applies more weight on the rubber drive roller and helps give more traction thus less
PRE-OPERATION

11
rollers
GR7000C GOLF GREENS ROLLER - Operation, Maintenance & Parts Manual
slipping or spinning of the drive roller will occur on or off the green.
• Whilst becoming familiar with the roller, set the throttle at about 1/2 speed. Press the left or right
foot pedal down gently the further the pedal is depressed the faster the roller will travel. Be smooth
with your action. Hold in this position until a short distance from the edge of the green, then take
your foot off the pedal gently until the roller comes to rest. Place your other foot on the opposite
pedal and gently apply pressure on the pedal. The roller will move in the opposite direction. Using
the left and right pedal in this manner, will ensure there is no damage to the green, less wear and
tear on the equipment and operator.
Remember high speed less torque, lowering the speed increases the power output.
• The correct procedure for rolling the green is:
(a) Select the correct direction to roll the green.
(b) Start on one side of the green and work your way across the green in a zigzag fashion,
slightly overlapping each lap you roll: this makes sure you miss no part of the green
and all of the green is rolled. Avoid coming back across the green to roll missed areas
if possible. You should be able to complete the rolling of 18 greens in the same time or
quicker than mowing using a triplex mower.
• When the rolling of the green is completed, move the roller onto the fringe, stop the engine, lock the
trailer into the trailing position, connect it to the towing vehicle then move off to the next green to be
rolled. Do not put the trailer down into the towing position on the green; damage may occur to the
green from the roller tires and body.
POINTS TO REMEMBER
1. Make sure the roller is serviceable before rolling.
2. Start rolling from the fringe of the green.
3. Smooth operation on the foot pedals.
4. Pick a point on the other side of the green to roll to.
5. Do not look at the green close to the roller; it makes it difcult to steer the roller; look well ahead.
6. Use 1/2 throttle until you are procient at operating the roller.
7. Move the steering joystick a little at a time to change direction; excessive movement of the joystick
makes it difcult to travel in a straight line.
8. Roll in straight lines; Zig Zag pattern, the roller is not designed to turn sharp corners.
9. Do not leave the roller engine running with the roller parked on the green; the engine vibration will
cause roller depressions to be left on the green.
10. Move off the green when rolling is complete before putting the trailer in the down position.

rollers
GR7000C GOLF GREENS ROLLER - Operation, Maintenance & Parts Manual
11. When rolling steep greens and the engine stops, check engine oil level. The engine is tted with a
safety switch; when the engine oil level is low the engine will stop.
12. Use oil as recommended by the manufacturer.
13.
CAUTION: Ensure emergency park brake is disengaged during operation. If not damage to the
rubber surface of the drive roller will occur.
MAINTENANCE
* Stop engine before performing any maintenance.
* Service the engine according to the manufacturers maintenance schedule.
*
Check Transmission oil level. The oil in the plastic container on top of the transmission
must be maintained at the level indicated on the container when the transmission is cold.
Important: Do not overll the plastic container, as the oil requires room to expand when hot.
* As a guide to correct transmission oil use Mobil 1 or Penrite Synthetic 5 5W-60
STORING
* It is important to store this roller in the towing position. This ensures the trailer strut is in the
closed position, protecting the shaft from corrosion, then failure.
SERVICE OF DRIVE SYSTEM
* Replacement - Use only the chain and Sprockets recommended.
* Tensioning the drive chain - No adjustment is required, the chain tension is automatically
adjusted.
EMERGENCY & PARK BRAKE
• To engage, push parking lever forward until it will travel no further, the lever operates on a over
cam principal, when it is fully engaged the lever will remain in this position with the brake applied.
To dis-engage the park brake, pull the lever up & back. The lever will remain in the off position until
re-applied.
