GR48 EATON GOLF ROLLER - Operation, Maintenance & Parts Manual
Step 1: MOUNTING THE SEAT TO THE SEAT FRAME
* Remove the circlip and the 12mm diameter pin from the seat frame
* Place the seat, with the seat back oriented toward the rear of the machine
(the front of the machine is the side where the pedals are located)
* Replace 12mm diameter seat locating pin through seat frame guides and through
the seat guide, replace external circlip on the end of 12mm diameter rod to prevent
the seat pin sliding out.
Step 2: MOUNT THE STEERING ARM TO THE MACHINE
* Select the steering joystick
* Place the keyed end of the steering joystick into the hole on top of the steering
support cylinder ( the cylinder is located directly behind the foot pedal and is approximately
12” high. There is a sealed bearing laying flat in the top and bottom of the cylinder.
* Slide the steering joystick into the hole until it rests against the shoulder. If the steering
joystick stops before reaching the shoulder, use emery cloth to polish the shaft. You may
also use a light oil on the bearing and shaft to allow the shaft to slide freely.
* Lift up the smoothing roller side of the machine so that you can get to the underside of the
machine. On the opposite side of the machine from the smoothing rollers, there is a
trailer pivot pin ( 25mm in diameter ) welded on the top of the body which will prevent the
machine from rolling on its side.
VERY IMPORTANT : Brace the machine so that it will not fall over. Secure the machine with
a rope or blocks to prevent the machine from falling.
* Locate the joystick shaft on the underside of the machine (Again, this is toward the front of
the machine).
* Locate the Woodruff Key. The Woodruff Key is a 3/4” x 3/16” thick piece of steel in the shape
of a half circle.
* Place the round-side of the Woodruff Key into the rectangular key slot on the
joystick shaft. Hammer or squeeze with pliers into place. When complete, the flat
side of the Woodruff Key should be parallel to the steering rod.
5.
GR48 EATON GOLF ROLLER - Operation, Maintenance & Parts Manual

MOUNTING THE STEERING ARM TO THE MACHINE CONTINUED
* Place the steering linkage assembly onto the steering shaft. The “shiny” arm or rod
end should be on the ground-side or lower side of the steering arm assembly.
* Line up the “square groove” on the steering arm assembly with the Woodruff Key with
your hand, slide or knock the assembly onto the joystick toward the bearing as far as it
will go and tighten the 5/16 Grub screw up against the joystick shaft . Make sure that
the steering linkage remains aligned with the Woodruff Key and the Woodruff Key
remains parallel to the rod when sliding the steering linkage on the rod.
IMPORTANT Do not reduce the thickness of the Woodruff Key. It is designed to be
a no tolerance fit.
Step 3: ATTACHING TRAILER ARMS TO MACHINE BODY
* Locate the trailer arm support rod, which extends out on each side of the machine.
Slide left side and Right side trailer arms, onto the Rod with the bends facing each
other. (The Rod is located between the Transmission and the Engine across the top
of the body )
* Fasten in position with 25mmn external circlip. Ensure circlip is fitted correctly into
the groove.
* Grease both trailer arm support rods.
Step 4: ATTACHING DRAWBAR TO TRAILER ARMS
* Locate the tow ball coupling assembly
* Gather the ends of the right and left trailer arms. Locate the two holes in the end.
* Place the tow ball coupling assembly between the trailer arms and align the holes.
* Place one 2 ¼” x 3/8” Head Bolt through each hole.
* Place one 3/8” UNF Nyloc Nut on each bolt and tighten.
* Test and ensure trailer latch is correctly locking in the down position. This is
important when trailing the machine.
6.
GR48 EATON GOLF ROLLER - Operation, Maintenance & Parts Manual

Step 5: ATTACHING WHEELS TO TRAILER ARMS
* Find the two wheels for the left and right side trailer arms
* Fill the tyres with the appropriate amount of air (to about 18psi). Do not exceed this
pressure.
* Onto one trailer arm, slide a wheel onto the shiny axle-rod. Ensure the rubber air filler
valve is facing out from the actual trailer arm.
* Place the 25mm External Circlip, 25mm Flat Washer on the end of the wheel axle,
ensure the circlip is fitted correctly in the axle groove to prevent the wheel from
sliding off the axle.
* Repeat the same procedure for the other wheel.
Step 6: ATTACH DAMPENER STRUT
* Locate dampener strut. Remove wrapping from unattached end.
* Remove the wire locking clip from the unattached end.
* Fit the ball socket on to the ball located on the trailer arm.
* Refit the wire locking clip.
* When roller is fully assembled, test the operation of the dampener. When it is
operating correctly it should allow the roller to lower to the ground gently and the
trailer will move up to its locking position, which will hold the wheels off the ground
whilst rolling.
* Coupling assembly should raise slowly. This prevents the operator from being injured.
Step 7: REPLACE ENGINE OIL
* A tag is placed on the engine’s On/Off switch indicating you must fill the machine with oil
prior to operation. The fluid placed in the machine is designed to keep the inside of the
engine from rusting until it is replaced with engine oil.
* Replace engine oil as described in the Honda or Briggs & Stratton Manual
Step 8: LUBRICATE ROLLER PIVOT BEARINGS
* There is a grease nipple covered with a plastic cap located on both smoothing head
centre ball joint swivels. Apply grease to lubricate fittings.
7.

GR48 EATON GOLF ROLLER - Operation, Maintenance & Parts Manual
PRE-OPERATION CHECKS
* Check engine as per Honda manual
* Ensure steering joystick has no looseness
* Check that foot pedal depresses under normal foot pressure.
* Ensure that the trailer bar locking catch mechanism is securely locked to the main frame
bolt when in the trailing position.
* Check and tighten grub screws fitted to joystick steering arm, and end bearing lock rings
on the rubber coated drive roller.
* Grease lightly smoothing roller heads centre ball-joint swivels. Replace plastic cap.
* Oil rod ends sparingly
* Check tyre pressure for proper operating pressure (18psi)
* Check for oil leaks - rectify before using machine.
STANDARD OPERATION PROCEDURES
* 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 drive roller. Maximum recommended
speed would be equal to a motorised 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.
* Greens can be rolled in any direction; 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 puts more weight on the rubber drive roller and helps give more traction,
thus less slipping or spinning of the drive roller will occur on 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 butnot suddenly. Be smooth with your action, hold in this

STANDARD OPERATION PROCEDURES CONT.
position until nearing the edge of the green, then take your foot gently off the pedal, the roller will
stop. Rest your other foot on the opposite pedal and gently apply the pressure on the pedal. It
then starts to move the roller into the opposite direction. Once again be gentle with the pedal, but
not sudden. By 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.
* 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 you 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 tyres 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 difficult to steer the roller; look well
ahead.
6. Use 1/2 throttle until you are proficient at operating the roller.
7. Move the steering joystick a little at a time to change direction; excessive movement of
the joystick makes it difficult to maintain a straight line.
8. Roll in straight lines.
9.

GR48 EATON GOLF ROLLER - Operation, Maintenance & Parts Manual
POINTS TO REMEMBER CONT.
9. Do not leave the engine running with the roller parked on the green; the engine
vibration will cause roller depressions on the green.
10. Move off the green when rolling is complete before putting the trailer in the down position.
11. When rolling steep greens and the engine stops, check engine oil level. The engine is fitted
with a safety switch; when the engine oil level is low the engine will stop.
MAINTENANCE
* Stop engine before performing any maintenance
* Service the Honda or Briggs and Stratton Vanguard 4HP engine according to the
manufacturers maintenance schedule.
* Check transmission oil level. The oil in the plastic container on top of the transmission should be
to the indicated line.
IMPORTANT Do not overfill the plastic container as the oil requires room to expand when hot.
* As a guide to correct transmission oil use Mobil 1 or Penrite 10-10th
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.
