Main Frame
The main frame includes 5 row 100mm x 100mm mounting ranks, of which front and rear centre section beams are 9mm for additional strength. The new low profile design frame allows easier fitment of air kits and other bolt–on accessories.
Hydraulic Loading
Larger models are standard with a 20 litre gas accumulator. This provides protection from pressure overload during working. In-line valves, fitted to the hydraulic circuitry, assist in controlling the recoil speed and force of the tynes as they return to the work position. A digital tyne breakout pressure gauge, fitted in the tractor cab, is an option.
Wing Fold System
Four 4”x30” folding cylinders are standard equipment – one on each hinge point.
Simple Leveling Adjustment
Two double acting lift cylinders fitted to the centre section are mechanically linked to the wings. There are no phasing cylinders. To level the machine front to rear, the castor linkages are adjusted and for ‘across the width’ levelling, the inner layshaft links control the centre to the wings.
New 800HL Tyne Assembly
The new re-engineered tyne assembly is easier to fit and does not add unnecessary additional weight to the machine. Also, servicing of the cylinder is a much simpler operation. The downward pressure can be adjusted to more than 205kg (450lb) and the tyne has an extra-large under-frame clearance of 800mm (31.5”). The assembly has the facility for locking tynes in the raised position, which is ideal when sowing on alternate rows. The tyne foot has two 1/2” bolts at 1 3/4” centres, which accepts a wide range of ground engaging tools.
Optional 1000lb Hydraulic Tyne Assembly
The John Shearer 1000lb Hydraulic Tyne Assembly, as fitted to the Shearer Trashworker, is an option on the single fold models. This assembly which can be adjusted ‘on the go’ up to tyne breakout force of 455kg (1000lb) features, 35mm diameter hardened pivot pin & bushes and a 50mm x 32mm (2”x 1 1/4”) section H.T. silicon manganese high carbon steel tyne. Each tyne is loaded by a 44.5mm (1 3/4”) diameter jump cylinder. Available on 10″ and above spacing.
