END OF YEAR MACHINERY GUIDE
THE John Shearer Pasture Drill offers more precision sowing – and therefore maximum germination – thanks to its unique double disc design.
The drill has many advantages to offer farmers, including a uniform seeding depth, a reduction of draft forces, trash handling ability, reduced soil disturbance and faster sowing speeds.
Using discs, rather than tynes, is particularly advantageous when producers are sowing into rocky conditions, while sowing with a double disc opener leaves smother soil profile and will assist in reducing water runoff.
The John Shearer Pasture Drill uses a spring pin to lock the press arm into place, which is used to control the depth and provides 6mm increments over 50mm travel.
The spring loaded opener has a mechanical screw assembly to easily adjust the mainspring to decrease or increase pressure for both opening coulters and the press wheel.
Downward force can be increased to help cut tough stubble residue, and in drier conditions penetrate the soil for good seed placement.
The spring breakout pressure can be adjusted up to 182kg (400 lb), and the unit has 254mm (10”) of vertical ground following capability.
For the hydraulic version, pressure is adjusted on the go from the tractor seat to suit soil types and conditions - a pressure gauge fitted into the system allows the operator to monitor the down pressure.
The John Shearer opener is designed to perform in many different soil types and condi- tions, with its compact design meaning that the press wheel is much closer to the sowing boot than most others on the market with remarkable benefits in terms of uniform seeding depth.
The opener is a true parallelogram based around two carriers - the mounting carrier which attaches the unit to either a square or diamond mounting frame, and the main carrier on which the ground engaging coulters (or optional tyne) and press wheel are attached.
The hydraulic version of the double disc opener features a spring return mechanism for transport.
The John Shearer Pasture Drill offers an investment, not just on time spent in the field but also in increasing yield benefits and soil improvement.
