General Information

:

It consists of a spiral auger of 225 mm dia and 100 mm pitch  actuated by a rack and pinion arrangement. The drive for the circular motion of the auger is effected through belt pulley and bevel gear transmission with a ratio of 1:1 from the engine pulley of the power tiller directly. The entire assembly is mounted on a rectangular frame with necessary bearings and fixtures. The hand wheel provided at the side of the unit can be effectively used for the depth control. For increased size of holes, replaceable type larger diameter auger bits of 250, 275 and 300 mm can be used. A balancing frame  attached to the hitch bracket assembly in the rear and a support wheel fitted in the front portion of the unit  counter the down suction offered by the auger while digging, ensure easy movement in the field, reduction of drudgery  and easy manoeurvability.
