The TS98 lawn sweeper from SCH is robust in construction to withstand prolonged heavy use. A differential mechanism on the brushes allows the sweeper to be manoeuvred in tight corners without the wheels 'scuffing'. The differential mechanism also allows both ground wheels to drive the pick-up brushes, giving it superior sweeping power. The height adjustment is simple. The main drive is transmitted by metal gears. The large capacity solid plastic catcher is rot & tear proof. Reversing into the tipping heap is always difficult, but it is made easier with the TS98 as it only has two wheels in contact with the ground. Manufacturer's 1 year warranty
