LOPRO 670 & 780 MANURE SPREADER – INSTRUCTION & SPARES MANUAL 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. Turn off the tractor and remove key before fitting PTO. 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. Maximum pull out of 12 inches of the 2 shafts. 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. Please refer to the DVD for more information. ...
LOPRO 670 & 780 MANURE SPREADER – INSTRUCTION & SPARES MANUAL 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. 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. Ensure the braking system is connected and that it functions correctly before moving. FLOOR RETURN SLURRY DOOR CLOSE FLOOR PRESSURE SLURRY DOOR OPEN Page 10 ...
LOPRO 670 & 780 MANURE SPREADER – INSTRUCTION & SPARES MANUAL 1.3 Floor adjustment. When adjusting floor chains ensure that the adjustment is carried out equally to both sides.

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. 1.4 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. 1.5 Slurry Door As the load height reduces lower the slurry door to cover the augers. This will help prevent foreign objects being thrown forward. Page 11 ...

LOPRO 670 & 780 MANURE SPREADER – INSTRUCTION & SPARES MANUAL 2.7 Tire & Wheel Maintenance of correct inflation pressure (46PSI) is the basic essential factor in obtaining the best performance and life from a pneumatic tire. The air inside the tire enables it to carry a load. It is only when the inflation pressure is correctly matched that the tire adopts its optimum cross‐sectional shape and the tread rests correctly on the road surface with the correct pressure distribution across its whole width, thus allowing the sidewalls to provide the required degree of flexibility. Both performance and life of the tires will suffer if pressures are unsuitable so both over or under inflation ( or overload which has the same effect ) are similary undesirable. Underinflation results in excessive deflection which increases the heat generated by the tire, this in turn leads to its eventual disintigration. In addition the distortion of the casing will result in the lifting of the centre of the tread, thus overloading the outer edges of the tread, producing rapid wear at those points. Overinflation distorts the tire’s casing, but in this case it tends to lift the outer edges of the tread off the road surface and imposes extra load and more rapid wear on the centre of the tread. Owing to reduced flexibilty the tire will be more vulnerable to impact damage, ride quality will be impaired and the wheels will be more liable to bounce which can result in skidding due to brakes locking. Unlike cars on which tire loads do not vary greatly it is not practicable to provide standard recommendations. This is because tire loading and operating conditions vary widely. ...

LOPRO 670 & 780 MANURE SPREADER – INSTRUCTION & SPARES MANUAL 6. IMPORTANT INFORMATION When using the speader in conjunction with a tractor which has a fast and slow response control on the spool valves, check that the control on the spool valve is not in the slow position in respect of the floor drives, as this will over ride the variable floor speed. The spreader always runs very quietly when working, if loud banging noises are heard this will mean that foreign objects are in the material. Obviously the shearbolt may well break. If the shearbolts on the PTO has not sheared and the noises persists STOP THE SPREADER SWITCH OFF TRACTOR ENGINE and check the spreader. From new, it is strongly recommended that you do not use a high pressure cold washer and definatley not a hot pressure washer to the outside of the spreader for 12 weeks. This will damage the paintwork whilst normal curing of the paint takes place. Careful low pressure washing is acceptable. Do not let manure dry and set on fresh paint for the first 3‐4 weeks. During this period it is advisable to clean the machine after use as instructed. Page 53 ...
