1. OPERATING INSTRUCTIONS
The intended purpose of the vehicle is to tow and spread manure and other materials.
1.1 HITCHING TO TRACTOR
Attach spreader to pick-up hook or static hitch stub. Do not attach to swinging drawbar or pick-up hook in
extended position.
Remove screwjack from drawbar (if fitted) and locate in the transport position provided at the front of
spreader.
1.1.1 CUTTING PTO SHAFT TO SIZE
Turn off the tractor and remove key before fitting PTO.
1. Slide the tractor end of the PTO shaft out and fit to the tractor PTO.
2. Lay the two halves of the PTO shaft alongside one another and mark the required lengths, allowing
for turning. Maximum pull out of 300mm (12 inches) of the 2 shafts.
3. Cut to size and clean the burrs at each end of the shaft
KEEP SHAFT SLIDING SURFACES GREASED.
Attach chains fitted to PTO guard (to prevent the rotation of the guard) to suitable point on the tractor and
the staple on the drawbar.
Ensure that the spring loaded pins in splined yokes are fully locked in position.
Always disengage the PTO when turning sharply to avoid damage to shafts universal joints. Where a
wide Angle PTO is fitted, attach this end to the tractor.

Page 11
1.2 COUPLING OF HYDRAULIC HOSES
Fit the two hoses for the floor drive hydraulic motor (one to feed and one for return) to double spool valve
on tractor. Choose position of spool lever for ease of control to obtain floor movement to rear. Reversing
of floor is done by selecting the opposite position of the hydraulic control lever. Universal quick release
probes are fitted as standard to hose ends. Mark hose as required to assist in the future coupling for
correct position of feed and return.
NOTE: CHECK DIRECTION OF FLOOR BEFORE LOADING.
Do not run floor in reverse with full load. Speed of floor in reverse is at MAXIMUM.
Only reverse floor for a few seconds.
When a slurry door is fitted connect the hydraulic hoses to a double spool valve and select the hose
positions to suit the operator to open and close the door.
Fit hydrualic brake hose to trailer brake valve on tractor (male fitting). A universal female brake coupling is
fitted as standard to the hose end.
Ensure the braking system is connected and that it functions correctly before moving.

LOWLANDER HD MK2 & WIDEBODY MANURE SPREADER – INSTRUCTION & SPARES MANUAL
Page 12
1.3 HANDBRAKE
The handbrake is a multi-stroke ratchet type. To apply the handbrake give the handle short pumps (a
clicking of the ratchet will be heard) until resistance occurs and subsequent tightening of the cable. To
release the handbrake give the handle one sharp movement in the opposite direction. This releases the
ratchet mechanism.
1.4 BRAKE ADJUSTMENT
1.4.1 HYDRAULIC BRAKES
Brake adjustment is carried out at the hydraulic brake ram unit fitted to each wheel axle giving
independent adjustment to each wheel. To adjust, jack up the spreader, slacken the locknut in the set
screw and turn the set screw clockwise. (See Section 6.2 HYDRAULIC BRAKE SYSTEMS)
BEWARE NOT TO OVER ADJUST. Make sure the wheel can rotate freely.
1.4.2 AIR (PNEUMATIC) BRAKES
See Section 6.3 AIR (PNEUMATIC) BRAKE SYSTEMS.
1.5 FLOOR ADJUSTMENT
When adjusting floor chains ensure that the adjustment is carried out equally to both sides.
DO NOT ALLOW THE CHAINS TO BECOME TOO SLACK.
ADJUST CHAINS AFTER A FEW LOADS.
KEEP CHAINS ADJUSTED CORRECTLY AT ALL TIMES, A GUIDE IS TO BE ABLE TO SEE A WHOLE LINK BELOW
FRONT BOTTOM EDGE OF SPREADER i.e. FROM CENTRE TO FRONT.
Reversing the floor
The floor should only be reversed for very short periods, to clear the augers.
Do not reverse if the floor chain is slack, tighten floor chain first.
1.6 METHOD OF OPERATION
1) Select speed of floor required on control valve.
2) Engage PTO to power the rear augers – tractor engine revs low.
3) Raise slurry door fitted.
4) Engage spool valve to power floor to rear.
1.7 SLURRY DOOR
As the load height reduces lower the slurry door to cover the augers. This will help prevent foreign objects
being thrown forward.

1.8 INSTALLATION AND GENERAL USE OF DETACHABLE SPINNER DECK
1.8.1 GENERAL USE
The detachable spinner deck is designed purely for wider spread patterns and low application
rates of between 1 and 3 tonnes per acre (2 ½ to 7 ½ tonnes per hectare). It must NEVER be used
to spread long straw-based materials or heavy applications beyond 5 tonnes per acre.
1.8.2 INSTALLATION
When fitting or removing the spinner deck assembly great care must be taken not to endanger an
assistant in any way, especially when raising or lowering the unit. Persons must not be put at risk.
Before making any adjustments, fitting or removing attachments, the tractor that the spreader is
attached to must be switched off and the key removed.
FITTING THE SPINNER DECK – See Section 8.8 (DETACHABLE SPINNER DECK) for parts list.
1. Remove guard from output spigots of the auger gearbox.
2. Slide one half of ‘flexi coupling’ onto the shaft, through shaft of spinner gearbox.
3. Slide other half of the ‘flexi coupling’ on the input spigot of the spinner gearbox.
4. Using approved lifting apparatus lift the complete spinner deck assembly using lower lifting
eye on canopy (ensure bolt & nuts No. 20/20 and 16/18 are securely in place).
5. Offer the assembly to rear of the machine and lower into position. Firstly, locate the
‘bucket hooks’ of deck into clevises at the top rear corners of the spreader.
6. Hinge hook bolt No. 14 into anchors and tighten.
7. Fit and tighten 4 bolts to join the two halves of the flexi coupling.
8. The machine is now ready for use with the spinner deck.

Page 14
REMOVING THE SPINNER DECK
1 Clean all material from spinners and decks.
2 Remove 4 bolts from the flexi coupling.
3 Loosen hook bolts No. 14 and hinge back to clear anchors.
4 Using approved lifting apparatus lift from lower lifting eye on the canopy firstly pulling the
bottom of the deck assembly away from rear of spreader to the clear auger blades.
5 Lift the assembly clear of the spreader and stand on level ground with the front of the
assembly close to, or against a wall or stable object.
6 Fit the shaft cover to the output spigot of the spreader beater gearbox.
7 The machine is now ready for use without spinner deck.
ADJUSTMENT OF CANOPY & BLADES
For the best results
1 Fix the canopy on the inner positions for light materials i.e. Poultry manure.
2 For heavy material i.e. slurry or sludge adjust canopy out as far as possible so as not to
deposit material beyond the deck into gaps between the discs.
3 To increase the width of the spread pattern adjust the angle of blades forward on the disc.
4 If the spread pattern is light immediately behind the machine adjust the angle of the blades
back.
5 It is possible to achieve an even spread by adjusting blades as opposing pairs. i.e Blade 1
and 3 in position 3 and blade 2 and 4 in position 1.

1.9 OPERATING INSTRUCTIONS FOR HORIZONTAL BEATERS
1.9.1 GENERAL USE
The horizontal beater with spinner discs is designed primarily for wider spread patterns and lower
application rates for product such as chicken and turkey manure, however long straw based
materials can be spread effectively. It must be expected that application rates maybe slower than
a vertical auger spreader.
1.9.2 ADJUSTMENTS FOR SPREAD PATTERNS
The position of the lower section of rear canopy and the angle of the blades on the discs will affect
the spread pattern and width.
Select a hole position that places the rubber strip over the middle of the discs for a lighter
application rates and wider widths. Adjust the hole position to move the rubber strip rearwards
for higher application rates e.g. for straw-based materials. Excessive rearward adjustment will
cause the material to miss the discs and hit the ground without being spread.
Each spinning disc is supplied with 2 blades on and the others loose; it has been proven that many
materials are spread more effectively with just 2 blades per disc.
1. To increase the width of the spread pattern, adjust the angle of blades forward on the disc.
2. If the spread pattern is light immediately behind the machine adjust the angle of the blades
back.
3. It is possible to achieve an even spread by adjusting the blades, as opposing pairs. i.e.
Blade 1 and 3 in position 3 and blade 2 and 4 in position 1.
4. When adjusting angle use the 2nd set of holes on the blade to keep the tip of the blade on
the edge of the disc
