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 transport position provided at
the front of spreader.
Slide the tractor end of the PTO shaft out and fit to the tractor PTO. Lay the two halves
of the PTO shaft alongside one another and mark the required lengths, allowing for
turning. Minimum of 150mm (6 inches) engagement of the two halves. Cut to size and
clean burrs at each end of shaft KEEP SHAFT SLIDING SURFACES GREASED. Attach
chains fitted to PTO guard (to prevent rotation of guard) to suitable point on the tractor
and hole provided on metal cover over PTO shaft on spreader. 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.
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 port
of rearward floor movement in tractor cab. 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. 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 ends.
N.B 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.

1.3 Hand brake.
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 to the left. This releases the ratchet mechanism.
1.4 Brake adjustment.
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 pages 89 & 90)
BEWARE NOT TO OVER ADJUST. Make sure the wheel can rotate freely.
1.5 Floor adjustment.
When adjusting floor chains ensure that the adjustment is carried out equally to both
sides. ( See page 19)
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.
Reverse 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. (See page 19)
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) 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.

2. MAINTENANCE
2.1 Lubrication of spreader.
DAILY GREASE Front and rear floor shaft
Overrun clutch to front of main ‘T’ gearbox
WEEKLY GREASE All sealed bearing –2 pumps of grease gun maximum.
TAKE CARE NOT TO DAMAGE GREASE SEAL BY OVERGREASING
Sliding tube of PTO shaft.
PTO universal joints –Follow instructions as for sealed bearings.
Screwjack top (when fitted)
Shearbolt bush
MONTHLY Check gearbox oil levels
ANNUALLY Change oil to all gearbox
TYPE OF LUBRICATION GREASE Multi purpose
GEARBOXES EP90
2.2 Shearbolt Protection.
Only one shearbolt is fitted to the spreader. This is located on the spreader end of the
PTO shaft. The bolt is M10 x 60 grade 6.8 mild steel.
ON NO ACCOUNT MUST A BOLT OF HIGHER GRADE THAN 6.8 TENSILE STRENGTH BE
FITTED.
2.3 Pressure relief valve to floor drive.
This valve is cross line type and fitted to the hydraulic motor on the floor drive gearbox.
The pressure can be varied to suit the material being spread. To adjust, engage the oil
flow via the spool valve on the tractor, slacken the locknut and insert an allen key and
turn clockwise to increase pressure until the floor starts to move. Tighten the locknut.
To decrease the pressure, reverse procedure. When making this adjustment, the
spreader pressure will be set lower than the tractor PRV. A diagram in the floor drive
section of this manual shows which screw relieves forward motion and which screw for
reverse motion of the floor.
It is recommended to apply waste oil to the floor chains periodically when spreading dry
material and particularly at the end of the spreading season. This assists in the smooth
running of the machine and prolongs the working life of the components.
