RE50 Owner’s Manual
Safety Information
Safety is of the utmost importance when operating
turf equipment.
To ensure safe operation of the RE50 Golf Greens
Roller, please follow the following safety guidelines.
• Always make a pre-operation inspection before 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
person to use this machine. Unskilled persons can
harm themselves and others if they operate this
machine.
• When transporting the roller or carrying out
maintenance, make sure the trailer lockdown
mechanism is secured by the locking pin to prevent
premature release of the catch.
• If the trailer catch is not correctly engaged while
towing and releases accidentally, the front of the
roller can drop and dig into the ground, causing the
machine to move dangerously in any direction
causing bodily injury and result in damage to the
drive roller and other components.
• When the roller is running, always keep hands and
loose clothing away from rotating shafts, chains,
belts and sprockets in the transmission area.
• It is recommended to wear appropriate person
protection equipment, (PPE), as per local laws.
These may include hearing protection, eyes and
appropriate closed shoes and clothing PPE.
Environmental conditions should also be taken into
consideration.

RE50 Owner’s Manual
Standard Operation Procedures
1. Inspect and check that the roller is serviceable prior to
departing from the workshop. Ensure the batteries are fully
charged.
2. Use a suitable towing vehicle to move the roller from green
to green.
3. Maximum recommended towing speed would be equal to
a motorized golf buggy, i.e., approximately 10-12mph/
19-19kph. 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 on
the operator’s ability.
7. To drive, switch the key to the ON position. Select the
direction of travel with the 2-way switch that is fitted on the
top of the joystick. To travel left push the switch to the left,
to travel to the right press the switch to the right. After
selecting the direction of travel depress the foot pedal
down until you have reached your desired operating
speed. Changing directions, can be done on the fly.
The roller will gently come to a stop under regenerative
braking and then gently take off in the opposite
direction until it reaches the chosen speed or full
speed. The other method of operation is to use the
accelerator pedal to slow down to a stop, change
direction with the switch then accelerate off in the
opposite direction. To s t o p , t a k e y our foot o!the foot
pedal and the machine will automatically come to a stop.
8. Adjusting position of the accelerator pedal:
a) Loosen the two bolts located at the rear outer
corners of the foot pedal assembly, do not fully
remove the bolts.
b) Slide the foot pedal assembly towards the front
or rear until you find the most comfortable
position to suit your leg and foot.
15

RE50 Owner’s Manual
Standard Operation Procedures
9. 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.
10.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.
11. When using the pin hitch style drawbar, the following 3
points must be adhered to.
a) Ensure that the hole size in the tow hitch fitted to the
towing vehicle is at least 3/8” (10mm) larger in
diameter than the pin size fitted 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 as damage
to the pin hitch will occur.
c) Do not cross excessively steep hills or dips where
the tow hitch pin may gouge the turf and damage
the drive roller.
12. Keep the roller on the greens surface. It is not
necessary to roll onto the collars or fringes.
13. The operator needs to become familiar with the
timing required to stop and the distance required
to do so at the speed being travelled,
remembering that the roller is quite heavy.
14. There is a park brake fitted to the roller. This is to
be used only in an emergency or when parking
or leaving the machine on an incline. The park
brake should not be used in the normal
operation of the roller.
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.

Standard Operation Procedures
Park Brake
The park brake lever operates on an over-centre
principal.
To engage the park brake, pull the park brake
lever fully up and back.
The park brake lever will remain in this on position.
To disengage the park brake, push the park brake
lever fully forward and down.
The park brake lever will remain in this off
position.
Important: Always operate the roller with the park
brake off!
Caution: Do not operate the roller with the park
brake engaged as this will damage park brake
components.
When stopping and before getting off the
machine always apply the Park Brake.
Towing
17
Ensure that the safety pin
is correctly fitted in place,
before towing commences.

RE50 Owner’s Manual
Points to Remember
• Ensure batteries are fully charged.
• 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
difficult to steer the roller straight. Look well ahead.
• Use 1/2 throttle until you are proficient 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
difficult to maintain a straight line.
• Roll in straight lines.
• Move off the green when rolling is complete before
putting the trailer in the down position.
• Extra effort maybe required to raise the roller off the
ground into its towing position. An optional extension
bar is available for purchase to extend the drawbar
length. Once fitted, it is stored on the drawbar using
the spring clip. This extra length added the drawbar
gives the operator more mechanical advantage,
making it easier to raise the roller into its towing
position.
