Paxton Plow DT7 chisel plough
Paxton Plow develops new DT7 series chisel plough
The new Paxton Plow DT7 series chisel plough is heavier and stronger than before, and has broken ground for the first time in Mingenew, Western Australia.
Prone to hardpans, Mingenew’s compressed yellow sandover-clay affects root development, moisture uptake and yields, requiring the land to be deep-ripped to combat the problem.
Asked by a local farmer to develop a sturdier plough with longer tines, and a better underframe clearance to combat blockages and tough terrain, Paxton Plow Co came up with the DT7 series chisel plough.
Paxton Plow’s Wade Smith says the DT7 Series development showed how the company was successfully locally engineering and building machines for local Australian conditions.
“The plow’s weight and strength are built into the frame and the dual wheels have been specified to carry that weight easily,” Smith says.
“The tines, while based on the principles used in the SR Series plow tines, have a modified trip-head design and more material in the top half of the shank. This is where their strength to handle depths up to 750mm comes from – 250mm more than the 500mm the well-respected SR Series is designed for.”
Set to work at a farm in Mingenew, the farm owner says the new Paxton Plow DT7 plough has overcome issues 30 years’ old.
“We’ve been deep ripping for 30 years and we’ve always had issues with other machines, mainly blockage problems because the tines were too short and the frame clearance was inadequate,” the owner says.
“While some people say after you’ve ripped two or three times the going gets easier, but that isn’t our experience here.
“Sometimes it’s easy and other years it’s like pulling the ripper through concrete, so, you don’t know what it will be like and you need a pretty robust machine for the hard years,” he adds.
In saying that, Paxton Plow says the new DT7 plough is heavier and stronger than its SR Series plough brothers with the DT7 plough capable of working as deep as 750mm. The farm’s usual deep-ripping and spade cultivation program reaches down to about 350mm, which is then followed by direct drilling.
With previous ploughs unable to break though the tough hardpans of Mingenew, the farm operator is happy with the performance of the DT7 series plough.
“A test run showed it went into the ground like it was supposed to and did what it was supposed to – perfectly satisfactory,” he says.
The DT7 will truly get to work next autumn, preparing ground for the 2018 crop of lupins, wheat and canola.
