1.0 Introduction
The ELMOW 20/24 mower consists of a 20/24” 10 bladed cutting cylinder, bottom
blade, a powered groomer, two electric motors and a driven rear roller.
The cutting cylinder is driven by an 180W electric motor via a timing belt drive. The
land roller is driven by a second 180W electric motor driven via a worm and wheel
gearbox and a final chain and sprocket drive. The land roll has an internal differential.
Each motor is controlled by a separate controller. Power is provided by a 24V
rechargeable battery pack. A battery charger/conditioner is used to charge the
battery pack when it is electrically disconnected from the mower.
The ELMOW mower is designed solely for cutting high quality turf. Use in any way
other than that stated is considered contrary to the intended use. Compliance and
strict adherence to the conditions of operation, service and repair as specified in this
manual also constitute essential elements of the intended use.
The way in which the ELMOW mower is operated and maintained will have a
profound effect on its performance and reliability.
An ELMOW mower should be operated, serviced and repaired only by persons who
are familiar with its particular characteristics and who are familiar with the relevant
safety procedures
The safety precautions outlined in this manual and all other generally recognised
regulations on safety must be observed at all times.
Any modifications carried out to an ELMOW mower will relieve Turfmech Machinery
Limited of liability for any resulting damage or injury.

10.1 Adjusting the bottom blade
WARNING - Always wear gloves and disable the battery pack when
handling the cylinder. Do not touch rotating blades.
•Remove the battery isolation key, tilt the mower backwards.
•Hold a thin piece of paper between the edge of the bottom blade and the
cutting cylinder
•Turn the cutting cylinder slowly by hand.
•If the blade is set properly the paper should cut cleanly along the full length of
the cylinder. If it does not then proceed as described on the next page.
•Locate the two bottom blade adjusters (1 in Figure 1).
•The adjusters alter the gap between the bottom blade and the cutting
cylinder. Rotate the adjusters clockwise to increase the gap. Rotate the
adjusters anti-clockwise to decrease the gap. See Figure 2 for clarity.
•Adjust the clearance between the bottom blade and the cutting cylinder so
that the paper is cleanly cut at all points across the blade. Frequently use the
paper to test between each adjustment.

Figure 2: Bottom blade adjustments
Do not over tighten the bottom blade – the cylinder should be able to
spin freely.
•If you are still unable to cleanly cut the paper, inspect the bottom blade
and cylinder. If they appear rounded or damaged they may need to be
sharpened or back lapped. Back lapping involves applying a suitable
grinding paste (180 grit) to the bottom blade, then running the cylinder
backwards. This hones the cylinder to create a fine tolerance between it
and the bottom blade.

The bottom blade adjusters can sometimes become very tight and may be hard to
turn. If this is the case:
•Slacken off the grub screw on the collar
behind the adjuster as shown.
•Rotate the adjuster anti-clockwise 1/8
th
of
a turn.
•Tighten the grub screw.
•Check the adjuster – it should now turn
freely.
•Carry out blade adjustment as described
previously.

Figure 3: Bottom blade adjuster
10.2 Adjusting the height of cut and groomer height
•Always set the mower on cut before attempting to set the height of cut.
•Use the height setting bar provided to set the height of cut and groomer
position. The bolts on this should be adjusted until they reach the desired
height of cut (X) and the desired groomer height (Y) as shown in Figure 4
below.
Figure 4: Height of cut and groomer depth
•Once adjusted, position the setting bar so that the underside of the bolt head
(X) rests on top of the leading edge of the bottom blade. The rearward end of
the bar must make contact with the rear roller as shown by Figure 4 above.
•Adjust the height of the front roller until the setting bar just touches it.
•To alter the position of the front roller, rotate the quick height adjuster
clockwise to reduce the height of cut and anti-clockwise to increase the height
of cut. One click moves the front roller by an increment of 0.3mm (1/80 of an
inch), this alters the height of the blade by 0.175mm (7 thousandths of an
inch). 1 click = 0.175mm, 3 clicks = 0.525mm (1/50”), 6 clicks = 1.05mm
(1/25”) etc.

•To alter the height of the groomer:
-When not needed the groomer can be lifted out of work. Firstly ensure
that the groomer is lowered out of the transport or out of work position.
-To do this, loosen the transport position knobs on each side of the mower
chassis (3 in Figure 1)
-Ensure that the groomer is in its lowest position, tighten the knobs and
check the height.
-To make height adjustments use the hand wheels (4 in Figure 1). Rotate
clockwise to increase grooming height and anti-clockwise to reduce it.
10.3 Cylinder and bottom blade grinding/reconditioning
The cutting performance of the ELMOW mower is highly dependent on the condition
of both the cylinder and bottom blade. Poorly maintained parts will lead to poor
quality of cut and have a detrimental effect to battery performance.
It is advised that the grinding/reconditioning of the cylinder and bottom blade be
carried out by either Turfmech Machinery Limited or a registered Allett dealer.
The bottom blade of the Tournament mower should be ground with a 5
O
angle as
shown below.
Figure 5: bottom blade angles
10.4 Forward speed and Clip rate
The clip rate is the number of times a cylinder blade passes the bottom blade over a
1 metre distance. The ELMOW clip rate is set at 246 cuts per metre. Three speed
options can be selected to suit different operators preferred mowing speeds. The clip
rate will automatically increase as forward speed is increased on the rotary speed
switch.
10.5 Chain and belt tension
The tensioning device for the land roll chain and cylinder timing belt can be found by
removing the left hand chain case cover. To tension the chain, slacken the plastic
chain adjuster bolt and reposition in the slot provided in the chassis. To tension the
timing belt drive, slacken the idler bearing bolt and reposition in the slot provided in
the chassis. The tensioning device for the groomer can be found under the left hand
chain case cover. To tension the 1/2” chain, slacken the compound sprocket and
reposition in the slot provided in the chassis. The 3/8” chain has a sprung automatic
tension mechanism.

dealers will prolong the working life of the machine and safeguard the warranty.
•Remove the battery isolation key before carrying out any maintenance work
•Keep all nuts, bolts and screws tight to be sure the equipment is in safe
working condition.
•To reduce the fire hazard, keep the battery and motor enclosure free from
grass leaves or excessive grease.
•Check the grass catcher frequently for wear or deterioration
•Replace worn or damaged parts for safety
•Be careful during adjustment of the machine to prevent entrapment of the
fingers between moving blades and fixed parts of the machine.
16.1 Inspection of critical safety components
The below components are critical to the safe use of the mower. Check they are in
good working order regularly.
•Operator presence control levers – The cylinder requires two separate
operations to start. Firstly the presence of an operator is confirmed by holding
one of the operator presence levers, secondly the cylinder is activated by the
unlatching and pressing the cutting cylinder controller activation switch into
the ON (1) position. If ONE of these operations starts the cylinder seek advice
from your nearest Allett dealer.
•Battery isolation key and switches – The correct operation of switches and the
battery disabling device are important. Check all wiring and connections are
in good condition. Replace any suspect components. Contact your local Allett
dealer for advice.
•Throttle control – When no operator is present the control should return to
neutral and the brakes will automatically be applied. If any problem occurs
seek advice from you nearest Allett dealer.
•Batteries – For safety Valve Regulated Lead Acid (VRLA) batteries have been
used. In the unlikely event that these fully sealed batteries leak, use suitable
protective clothing to protect against the corrosive acid. See the battery
section for further information.

18
•Vibration mounts – Vibration mounts isolate the operator from vibrations
which can be potentially harmful if experienced over a prolonged period of
time. Check the rubber isolators have not deteriorated in any way. Replace if
necessary.
•Grass box and guards – Check the grassbox and guarding for wear, replace
any damaged or missing guards immediately.
•Motors and brakes – The land roll drive motor has an inbuilt park brake. For
safety it is powered off. If the brake fails to hold properly check the connectors
to the controller and consult your local Allett dealer.
•Controllers – The controllers manage all the associated inputs and outputs of
the mower. Controllers are essential to the safe operating of the mower. If the
safety functions of the mower do not operate as described in this manual,
remove the battery isolation key, check the wiring then contact your local
Allett dealer.
•In case of abnormal vibration stop immediately and remove the battery
isolation key. Visually check for blockages, obstructions or incorrect operating
settings. If no cause can be found contact your local Allett dealer.
