Power harrows 175–300 cm

Landforce power harrows are made in six working widths, from 175 to 300 cm in steps of 25 cm, and the model designation corresponds to the working width. The narrowest model has 7 rotors and 14 blades, and the widest 12 rotors and 24 blades; in every model, the number of blades is twice the number of rotors. The blades measure 285 x 12 mm, and the maximum working depth is 280 mm.

The required tractor power increases with width, from 60–80 hp for the 175 cm model to 90–95 hp for the 300 cm model. The weight without roller ranges from 605 to 810 kg and the length from 1,855 to 3,080 mm, with a width of 1,501 mm and a height of 1,210 mm. Drive is from a 540 or 1000 rpm PTO via gears, and the driveline is protected by a slip clutch; a driveline with an automatic clutch is available as an option. The harrow is attached at three points, Category II.

Behind the rotors, a packer roller with a diameter of 450 mm or a cage roller with a diameter of 360 mm can be used, and roller adjustment can be automatic, by pin or hydraulic. The leveller is mechanical. Compared with the LMT rotary tillers from the same range, the power harrows require more powerful tractors: at least 60 hp, compared with 15 to 40 hp for the tillers.
