Philip Watkins’ mounted Tri-Till cultivator combines auto-reset sub-soiler tines with scalloped discs and a packer or press.

In fact, the company now offers the choice of Simba’s Double-D rings, its own ridged packer roll or serrated Guttler press which is said to give a finer finish when looking to establish oilseed rape.

Compared to the firm’s heavyweight Quad-Till cultivator which requires a minimum of 100hp per metre, a 3m Tri-Till needs 150-200hp up front to produce a decent one-pass finish. It costs £16,000.
