you start rolling. If this procedure is not carried
out damage to property or personnel may occur.
• Keep children, pets and inexperienced personnel
away from the machine. This machine should only
be operated by trained and skilled personnel -
check with your supervisor if you are unsure.
• Know how to stop the machine when in motion.
Read and understand manufacturers manual, as
supplied.
• Never permit inexperienced operators to use the
machine. This machine requires certain knowledge
and expertise to operate it; you must be a trained

Assembly Procedure
Step 1: Mounting the seat to the seat base.
• Fit the armrests to the seat pan using the supplied
screws, make sure the screws are all tightened.
Step 2: Mount the steering joystick to the steering
shaft.
• Select the steering joystick.
• Slide the joystick into the slot on the top of the
steering shaft, already installed in the steering
column directly in front of the foot pedal controls,
insert the 3/8” bolt into the bottom bolt hole,
select a comfortable operating position, push the
joystick forward for extra operating room or back
for less, once determined insert the other 3/8”
bolt into the upper hole and tighten both bolts
securely.
Step 3: Attaching the left-hand trailer arm to
machine body.
• Locate the trailer arm support axle 30mm in
diameter (1 1/4”) which extends out on the left
side of the machine, remove the circlip from
the support axle. Grease the machined portion.
Slide the left hand side trailer arm, onto the axle,
replace the circlip, ensuring the circlip is located in
the groove correctly.
Step 4: Attaching dampener strut and right hand
trailer arm.
• Locate the trailer arm support axle 30mm in
diameter (1 1/4”) which extends out on the right
side of the machine body, remove the circlip from
the axle. Hold the right side trailer arm in the
vertical position and slide it part way onto the
axle after greasing the shaft. Locate dampener
strut, remove packing from the unattached end.
• Apply thread lock “Loctite” to the M10 bolt
attached to the dampener strut. Screw the M10
bolt into the strut support on the trailer arm.
• If necessary use a soft headed hammer to tap the
trailer arm onto the axle until the circlip groove is
revealed, t the circlip, ensuring it is located in the
groove correctly.

Assembly Procedure
Step 5: Attaching draw bar to trailer arms.
• Locate the draw bar assembly.
• Gather the ends of the right and left trailer arms.
• Place the draw bar assembly between the trailer
arms and align the holes, ensure it is in the
correct direction as per the manual drawing.
• Place one 2 1/2” x 3/8” bolt through each hole, t
3/8” Nyloc nut to each bolt and tighten securely.
• Test to ensure the trailer catch is correctly locking
the trailer arms in the down position and the
catch locking pin ts correctly when transporting
the roller, for safety.
Step 6: Attaching wheels to trailer arms.
• Locate the two wheels for the left and right side
trailer arms.
• Check tires for the correct air pressure,
approximately 18-24psi. Do not exceed this
pressure. The tires act as the suspension, hence
the low P.S.I.
• Remove wheel nuts from both hubs, slide wheels
onto hub with air valves facing outwards. Replace
wheel nuts and tighten securely.
• Ensure the taper on the nuts, mate into the wheel
tapers correctly.
Step 7: Correct dampener strut operation
• When the roller is in the trailing position:
1. Carefully hold the draw bar assembly.
2. Lower machine until the front rests on the
ground.
3. Release the locking catch.
4. Gently with a rm grip begin to raise the draw
bar.
5. When it has travelled suciently the dampener
strut will take over and prevent the trailer arms
rapidly rotating on it’s axle, allowing the roller
to lower to the surface gently.
This prevents the operator from being injured.
When the roller is resting on the ground push the
trailer arms back gently, (do not use excessive force)
until the trailer arms will travel no further.

11
www.truturf.comRB70 Owners Manual
The dampener strut is designed to hold the trailer
arms back behind the operator with the wheels
o the ground. The trailer arms will remain in this
position whilst rolling the greens.
Step 8: Lubricate smoothing head pivot bearings.
• There is a grease nipple or zirk located on the 3
smoothing head centre ball joint swivels. Apply
grease to lubricate ttings.
Assembly Procedure

12
www.truturf.comRB70 Owners Manual
Ensure steering joystick has no looseness.
Check that foot pedal depresses under normal
foot pressure.
Ensure that the draw bar locking catch
mechanism is securely locked to the main draw
bar and the safety pin is tted when trailing the
roller.
Check and tighten grub screws tted to the end
bearing lock rings on the rubber coated drive
roller and the spiker shaft bearings (if tted) &
pivot bearings on each smoothing head.
Grease lightly bearings tted to drive roller,
spiker shaft (if tted) and Smoothing Head pivot
bearings. Replace plastic caps if missing.
Oil rod ends, sparingly.
Check tire pressure for proper operating
pressure (18-24psi). Do not over inate.
Pre-Operation Check List

13
www.truturf.comRB70 Owners Manual
Standard Operation Procedures
1. Inspect and check that the roller is serviceable
prior to departing from workshop.
2. Use a suitable towing vehicle to move roller
from green to green.
3. Maximum recommended towing speed
would be equal to a motorized golf buggy.
Approximately 4mph/7kph. Towing at excess
speed or across rough terrain may cause
damage to the machine and trailer.
4. When approaching the green do not tow the
roller onto the green to set up, put the roller
on the fringe of the green. Put trailer in the up
position, switch on the roller and drive it onto
the green.
5. Greens can be rolled in any direction; take care
to ensure there are no crease lines produced on
the surface.
6. It is recommended that you place the smoothing
head rollers on the high side of the green when
rolling. This increases the weight onto the
rubber drive roller and creates better traction,
it also reduces slipping or spinning of the drive
roller on the green, depending also on the
operators ability.
7. The correct procedure for rolling the green is:
(a) Select the correct direction to roll the green,
remember this roller can roll the greens in all
directions.
(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 don’t miss any 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 by mowing using a
triplex mower on a single charge.

14
www.truturf.comRB70 Owners Manual
8. When rolling of the green is completed, move
the roller onto the fringe, switch o the ignition,
lock the trailer into the towing position, connect
it to the towing vehicle then move o 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.
9. When using the pin hitch style draw bar, the
following 3 points must be adhered to.
a). Ensure that the hole size in the tow hitch
tted to the prime mover is at least 3/8”
(10mm) larger in diameter than the pin
size tted on the roller draw bar hitch.
b). When towing forwards or reversing, be
sure that the roller is not put into a jack-
knifed position, if it is, then damage to the
pin hitch will occur.
Standard Operation Procedures
c). Do not cross excessively steep hills or
dips where the tow ball pin may come in
contact with the tow hitch hole.

15
www.truturf.comRB70 Owners Manual
• Make sure the roller is serviceable before rolling.
• Start rolling from the fringe of the green.
• Pick a point on the other side of the green to
roll to.
• Do not look at the green close to the roller; it
makes it dicult to steer the roller straight; look
well ahead.
• Use 1/2 throttle until you are procient at
operating the roller.
• Once you choose your rolling line hold the joystick
steady, correcting direction gently as required.
• Move the steering joystick a little at a time to
change direction; excessive movement of the
joystick makes it dicult to maintain a straight
line.
• Roll in straight lines.
• Move o the green when rolling is complete before
putting the trailer in the down position.

Maintenance
Service of the drive chain system
• Replacement - use only the chain and sprockets
recommended as per the correct spare parts
number. Wrong pitch drive chain tted will cause
excessive sprocket wear and possible drive failure.
Service of smoothing roller bearings
• Whilst the Roller is suspended by the Trailer, check
operational smoothness of the bearings tted to
each smoothing roller by rotating the rollers by
hand. If bearing tightness, roughness or excessive
looseness is detected, replace the faulty bearings.
• If bearings are faulty
(a) Remove the complete smoothing head
unit assembly from the machine, undo the
four swivel mount bolts on the upper body
and disconnect the steering rod, wheel the
roller away until the total head assembly is
exposed to work on.
(b) Remove roller shaft bolts from end plates,
remove rollers from the heads.
(c) Fit new bearings, replace rollers into the
heads, lubricate shaft bolts with an anti-seize
compound before installing them. Tighten
securely and ensure rollers rotate freely
when fully tightened.
(d) If the connecting rods are removed or
lengths altered ensure they are correctly
adjusted so that the front heads are parallel
and the third head is parallel to the two front
heads when in the straight-ahead position.
Adjust if necessary.
