1. INTRODUCTION The Simba Folding Wing Uni-press is designed to give an improved surface cultivation effect whilst also ensuring consolidation to depth. The Uni-press may be towed on its own or in tandem behind another implement e.g. Disc Harrow. The use of the Uni-press in tandem with a disc harrow for straw incorporation is to consolidate the straw soil mix through the soil profile ensuring maximum straw soil contact to increase the breakdown process and minimise slug problems.
2. FOLDING AND UNFOLDING UNFOLDING 1. Ensure machine is fully raised. 2. Remove the transport strap from the rear wing cylinders. 3. Open the taps on the drawbar cylinders. 4. Ensure that the parking stands are in the fully raised position. WARNING: FAILURE TO STOW THE PARKING STANDS BEFORE THE PRESS IS UNFOLDED WILL RESULT IN SERIOUS DAMAGE TO THE MACHINE. 5. Operate the hydraulics to fully unfold the wings. 6. Check the wing pressure on the gauge.
3. HITCHING UP HITCHING TRACTOR UP TO UNI-PRESS NOTE:- When the Uni-press is parked, it SHOULD ideally be left in the unfolded, i.e. work, position for stability, safety and ease of access for maintenance 1. Couple the six hydraulic hoses to the tractor ensuring that the two wing hoses are together, the two drawbar cylinder hoses are together and the two levelling board hoses are together. 2. Connect the tractor to the drawbar using the hydraulics to raise or lower the height of the shackle. 3.
8. Open the shut off taps on the Uni-press drawbar. Operate the hydraulics to lower the drawbar tilting the Uni-press onto the road transport wheels. Fully extend the drawbar cylinders. 9. Fully raise the levelling boards so that when the Uni-press is folded the free ends of the levelling boards do not protrude beyond the 3m transport width. 10. Operate the hydraulics to fold the wings. 11. Operate the hydraulics to lift the disc harrow into the transport position. 12. Fit the disc harrow transport straps.
4. PREPARING THE UNI-PRESS FOR WORK 1. Ensure that the machine is fully raised. 2. Remove the transport strap from the wings. 3. Open the taps on the drawbar cylinders. 4. Ensure that the wing parking stands are fully raised and locked into the wings. WARNING: FAILURE TO STOW THE PARKING STANDS BEFORE THE UNI-PRESS IS UNFOLDED WILL RESULT IN SERIOUS DAMAGE TO THE MACHINE. 5. Operate the hydraulics to fully unfold the wings. 6. Operate the hydraulics to fully raise the levelling boards.
5. OPERATION In work the wing cylinders should be fully extended and the chassis horizontal front to rear. The gangs are able to float over any undulations on the ground due to their floating frames. Optimum performance has been found to be achieved when the press roll rings have worn away the painted finish leaving a smooth shiny surface. When the press roll rings are new or rusty, soil may tend to pick up on the surface and blockage may occur, this will reduce when the rings are shiny again.
LEVELLING BOARDS The action of the sprung leaf type levelling boards is to carry and drop soil to level in front of the press rings, to rub clod against clod for additional soil breakdown, to force clods down into the soil profile and to present remaining clods passing between the leaves into the front row of press rings. With the chassis set level, lower the levelling boards until they are carrying soil.
6. TRANSPORT With both machines in the transport position i.e. raised and folded, the top frame of the disc harrow should be slightly nose down or horizontal even when the downward load from the Uni-press is applied to the drawbar of the disc harrow. The top frame should NEVER be tail low in transport as this will give a high negative loading on the tractor which could lead to loss of traction to the rear wheels.
7. MAINTENANCE WARNING: WHEN WORKING ON MACHINE ALWAYS ENSURE IT IS FULLY SUPPORTED SHOULD BALANCE OF WEIGHT BE ALTERED, IF A ROLL GANG IS REMOVED FOR EXAMPLE. THE WING CIRCUIT IS CONTROLLED BY AN OVERCENTRE VALVE WHICH POSITIVELY LOCKS OIL FLOW UNTIL PRESSURISED BY THE TRACTOR. SYSTEM PRESSURE CAN BE RETAINED IN THE CIRCUIT EVEN AFTER DEPRESSURISATION OF THE TRACTOR QUICK RELEASE COUPLINGS.
WEEKLY SERVICE 1. Grease roll axle bearings until grease shows 2. Tighten all nuts and bolts including wheel nuts. Vibration through the machine may cause the nuts and bolts to work loose leading to wear. IMPORTANT: - Never use a hammer to assist tightening of nuts and bolts. - Using an incorrect size or grade of bolt may result in damage to the machine. MAXIMUM NUT AND BOLT TORQUES M16 GRADE 8.8 - 24 KG.M. (176 lb.ft.) M20 GRADE 8.8 - 48 KG.M. (352 lb.ft.) M30 GRADE 8.8 - 150 KG.M. (1100 lb.ft.
DOUBLE DISC RING AXLE MAINTENANCE The axles on this roller are tensioned by the main axle through the centre of the rings and bearings. SPECIALIST EQUIPMENT IS REQUIRED TO DISASSEMBLE THESE AXLES, PLEASE REFER TO PARTS LISTINGS FOR DETAILS. CONSULT YOUR APPROVED SIMBA DEALER UNDER ALL CIRCUMSTANCES IF DISASSEMBLY IS REQUIRED FOR ANY REASON.
WING FLOAT / CONTOURING The main wing sections are capable of following contours by means of a pressurised hydraulic system. A low pressure (approx. 10 to 20 bar) is set and held in the wing folding cylinders automatically as the unfolding procedure is carried out. In the unlikely event that this pressure needs to be adjusted refer to the following procedure. To Adjust the System Pressure PLEASE NOTE: - A low oil flow should be used, i.e., tractor tickover or low flow selected.
