The Min-Disc from Agriweld has been re-designed. A row of discs now cut a path through the soil and trash for the following tines which precede a second row of discs. Previously both rows of discs followed the tines.
“When the previous configuration was used in thick trash, such as pea haulm, it could get caught on the tines,” explains Harry Martin, design engineer at Agriweld. “The front row of discs now cut a path for the tines which we’ve found works very well”.
The concave, serrated, 508mm diameter discs are 250mm apart and every other disc is directly in line with a following tine, at 500mm spacing. Similar discs follow the tines and these are arranged to run in the spaces between the front discs.

The tines normally run around 250mm deep, depending on soil conditions, but on the re-designed, auto-reset version of the cultivator a double-acting ram can lift the tine out of the soil leaving just the two rows of discs and the packer in work.
The final change has been to add a longer hydraulic ram to the packer support which can now be lifted to a vertical position. This reduces the length of the cultivator, from the centre of the linkage to the rear of the scraper bar, to around 1.8m – about one metre shorter than the earlier version. This makes road transport easier and safer and helps when carrying the Min-Disc on a wagon.
Two models are available, the 2.5m with five legs and the 3.0m with six legs. The 3.0m auto-reset has a list price of £26,895.
