The machine uses two different drives; one which controls the wheels to move the machine forwards and the other which controls the digging tines. Because both drives are functioning simultaneously the machine is effectively doing all the work. The rotavator will keep digging for as long as it is in contact with the ground and in good conditions, and after a few passes, it can dig down to a depth of up to 8" (20cm). The digging depth is easily controlled via the control lever which is located on top of the digging box. To increase the digging depth simply move the lever up, or for shallow digging move it all the way in. With a 20" (52cm) rotavator box on the rear of the machine, the BCS 710 Rotavator is perfectly balanced. Combine this with a single forward and reverse speed and you've got a rotavator that's ideal for allotments and gardens and will quickly get your job done with the minimum effort on your part.
