1.0 Introduction
The Allett Wide Area Rotary Mower 86cm (Uplift) has been specifically designed to
collect debris from large areas of professional sports turf and sports Stadiums.
The walk behind pedestrian lawn mower is powered by a petrol engine. It is self-
propelled via a V belt clutch driving a 5 speed gearbox. The final reduction to the land
roll is chain driven. The land roll has an internal geared differential. Power is transferred
to the cutting blades from a blade brake clutch via a V belt and a toothed timing belt
drive.
The Uplift86 mower is designed for the management of 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 Uplift86 mower is operated and maintained will have a
profound effect on its performance and reliability.
A Uplift86 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 a Uplift86 mower will relieve Allett Ltd of liability for
any resulting damage or injury.
This manual is based on information available at the time of publication.
Allett Ltd reserves the right to amend product specifications without prior notification.

6.2 Stopping the engine
To stop the engine, proceed as follows:

Disengage the red blade engagement lever to
stop the blades
Release the land drive lever to stop the forward
travel
Move the throttle lever to the furthest
back position, this will STOP the engine
Engage the Park brake by pulling the
lever and latching it in place

13
6.3 Height of cut adjustment
The Uplift86 uses 2 micro height adjusters to move the front wheels and rear roller
simultaneously. This gives infinite control of the cut height.
Turn the hand wheels: Clockwise to cut higher
Anticlockwise to cut lower
Loosen the lower adjuster lock on both sides
Briefly tilt the mower back and return it to the ground
again to check the indicators read the same.
Tighten the adjuster lock on both sides
Release Front adjuster clamp locks on both sides
Lock front adjuster clamps on both sides

14
Tips:
When collecting debris for the optimum performance set the height of cut just
above the grass height.
For best results adjust the height of cut on a flat level surface.
Because of the high vacuum effect created by the blades it may be necessary
to set the height of cut to be greater than normal then gradually reduce to
meet the desired cut height.
6.4 Engaging drive to the cutting blades
6.5 Engaging drive to the land roll
When mowing, engage the blades first, then engage the forward drive.
When transporting the mower between work areas it is only necessary to
engage the forward drive only. Proceed as follows:
Lift the safety/operator presence lever to
the handle bar and continue to hold it all
the time whilst mowing
Pull back the blade engagement lever so
that it locks over centre. Before moving
forward, wait for 3 seconds to allow the
blades to reach full speed.
Note: Releasing the safety/operator
presence lever when the blades are
engaged will stop the engine
Select the appropriate gear. The fastest 5th
gear is located beyond the deck guard as
shown here
Disengage the Park brake by unlatching
the lever and pushing it down
To disengage the blades, push the red
lever forwards

15
Tip: When collecting heavy debris or cutting longer grass a slower forward speed will
improve performance.
6.6 Park brake

7.0 Maintenance
WARNING –Stop the engine, remove the spark plug cap and apply the Park brake
before carrying out any maintenance procedure detailed here. Always make the
mower SAFE before carrying out any maintenance.
To ensure long and reliable service, carry out the following maintenance regularly:
Regularly check for obvious defects such as a loose, dislodged or damaged blades,
loose fixings and worn or damaged components.
Check that covers and guards are undamaged and correctly fitted, this should also
include the grass bag. Carry out necessary maintenance or repairs before use.
Clean the exterior of the machine thoroughly using a soft brush and cloth. Remove all
debris, especially from the air filter and engine fins.
If the mower should happen to fail despite the care taken in manufacture and testing,
repair should be carried out by an authorised Allett dealer.
Lift the land drive engagement lever so that
it meets the handlebar and continue to hold
it to move forward.
Engage the Park brake by pulling the lever.
Whilst pulling the lever move it in the
direction of the handlebars. This will latch it
in one of the slots provided.

7.1 Adjusting land drive clutch cable
If the mower does not drive adequately when the clutch drive lever is held against the
handle bars it may be necessary to adjust the land drive cable. Proceed as follows:
Tools required: 10mm spanner x 2
7.2 Adjusting blade brake clutch cable
To operate correctly, the clutch needs a 23kg (50Lb) load to be applied. This is
applied via the spring and clutch cable.
IMPORTANT: The blade brake clutch has been factory set, a maintaining spring has
been fitted to keep the correct load applied to the clutch. Incorrect adjustments will
result in damage to the machine.
If the collection performance drops or the blades are slow to engage, first check the
load applied to the clutch. The blade brake clutch has been marked to show the
position of the activation lever when the correct load is applied.
To check the clutch load proceed as follows:
Make the mower safe, then tilt it back to view the clutch.
Using a spanner loosen the lock nuts
Move the adjuster OUT in the direction
shown. Make adjustments in small
increments checking progress by operating
the machine.
If the mower creeps forward before the clutch
drive lever is operated, move the adjuster IN
towards the front of the machine.
Tighten the fasteners

17
With the blade engagement lever pulled back, make sure the centre of the screw
head is aligned with the ‘run’ mark as shown below:
Release the blade engagement lever, make sure the centre of the screw head is in
the brake zone as shown below:
If necessary, to apply more force to the clutch proceed as follows:
Tools required: 17mm spanner x 2
Using a spanner loosen the lock nut.
Move the adjuster DOWN in the direction shown.
Make adjustments in small increments until the screw
head is aligned with the ‘run’ mark on the clutch.

This mower is fitted with a blade brake clutch. When the blade clutch lever is
disengaged the brake device ensures that the blades rapidly come to a stop. For
safety reasons it is important that the function of this device is checked daily. Check
that the blades start to rotate when the clutch lever is engaged and that they stop
rapidly when it is released. Make adjustments if necessary as outlined in section 7.2
above
7.3 Cable midway adjuster
If the mower does not drive forwards adequately it may be necessary to adjust the
cable as follows using the midway adjuster:
Tools required: 8mm spanner x 1
11mm spanner x 1
1) Slacken lock nut
2) Turn the adjuster a few times clockwise
3) Retighten the adjuster with the lock nut
7.4 Checking the engine oil
Change the engine oil after the first 5 hours of use. The oil should then be changed
every 50 hours or at the end of each season before storage, whichever is sooner.
1) Clean the area around the combined dipstick and filler cap
2) With the mower standing on level ground, unscrew and remove the engine oil filler
dipstick (8)
3) Wipe the oil filler dipstick clean: insert the oil dipstick, SCREW IT IN then remove it
again.
4) Check the oil level
5) Add a good quality SAE 10W-30 oil in small quantities at a time, allowing it to
settle. Repeatedly add oil and check the level until it reaches the upper limit.
If the blades turn before the clutch drive lever is
operated, move the adjuster UP towards the
handle bar. Making sure the screw head is with
in the ‘brake zone’

SAE 10W-30 oil is recommended for general use. It is important to use the
recommended oil to avoid damage to your engine. Engine oil capacity is 0.6L
7.5 General engine maintenance
Check and clean the air filter (10), replace if necessary. See engine manual for
details.
Check and clean the fuel sediment bowl and spark plug. See engine manual for
details.
For all other engine adjustments and maintenance refer to the engine manual.
7.6 Fuel
Petrol deteriorates over time. Engine starting may be difficult if you use petrol that is
more than 30 days old. Always run the fuel tank dry when storing for over 30 days or
use a Briggs and Stratton fuel stabiliser additive. Fuel tank capacity is 1.1L
Stop the engine before refuelling –petrol is highly flammable
1) Clean the area around the fuel filler cap
2) Remove the petrol filler cap (9), slowly add unleaded petrol to the tank, DO NOT
fill above the bottom of the fuel tank neck.
3) Replace petrol filler cap
4) Wipe up any spilt petrol from the engine before starting the mower
7.7 Grease points
A) Grease both spindles with 1-2 pumps of grease every 1-2 weeks.
B) Smear grease or light oil on the height adjuster threads and
drive chain every 1-2 weeks
C) The 5 speed transmission should remain sealed, if lubrication should
be needed use an Extreme Pressure (EP) grease. When empty the
transmission takes approximately 0.5kg of grease
D) Grease front wheel bearings with 1-2 pumps of grease
every 1-2 weeks.
7.8 Checking blade condition
The cutting performance of the Uplift86 is highly dependent on the condition of
the blades. Poorly maintained parts will lead to a poor quality of cut. Cutting
regularly in sandy conditions will accelerate blade wear, so blade condition
should be checked more frequently.
Excessively worn, chipped, bent or cracked blades should be replaced.
To check the blade condition:

Make the mower SAFE then tilt the mower back then use the prop/scraper to
secure the deck in a tilted position. Make sure the prop is placed securely
under the front of deck.
A new blade has an approximate 10 degree twist at each end and a bevel of
30 degrees for the cutting edge.
Tip: inspecting the cut plant is a good indicator of blade condition. If a “beard”
can be seen it is time for sharpening or fitting a new blade.
7.9 Blade removal
