Stiga twinclip mowers incorporate a 'twin clip' rotary cutter blade that cuts grass at 2 heights as it mows. These blades form part of stiga's xc extra collecting system, where cutting and collecting performance is increased by 20% compared to traditional straight cutter blades. Better collection results are achieved with the cyclone collection system which packs more cuttings into the grass bag. the twinclip 50 s self propelled combi mower from stiga has a 48cm 19 cutting width with 7 cutting heights ranging through 25 77mm that are controlled with a single point lever. The twinclip 50 s can be used as a combination mower cutting and collecting, rear discharging or mulching grass clippings. Cutting and collecting allows you to collect the grass clippings into the large 70 litre grass bag. The grass bag has a full indicator, minimising the amount of stoppage time in between emptying. The rear discharge option deposits the cuttings to the rear of the mower as you cut, perfect for longer more informal lawns. Mulching is a great option as it reduces the clippings down to fine pieces which are then deposited back onto the lawn where they virtually disappear. The extra fine cuttings provide your lawn with nutrients and moisture that promote healthier regrowth. the chassis on the twinclip 50 s is formed from a single piece of pressed steel then galvanised for durability. The added 4 step moulding process doubles the strength of the chassis. The inclusion of aluminium components to areas of the mower where rigidity and strength are crucial including the grass discharge chute allows for the hybrid steel aluminium chassis.specificationsmodel twinclip 50 stype 4 wheel combinationdrive yes, single speedtransmission pro aluengine stiga st170 autochokecapacity 160ccpower output 2.6kw 2900rpmstarter recoilchassis material galvanized steel hybrid alucutting width 48 cm 19 inchcutting heights 7 from 25 77mmcutting height adjustment single pointfolding handles yesadjustable handles yesgrassbag 70 litre capacity with bag full indicatorwheels front rear 210 240mm with ball bearingsmulch plug included yesside discharge nowashing link yesfront handle yesrecommended lawn size 50m x 50ma 0.6l bottle of engine oil is includedweight 49kgwarranty 5 year domestic terms and conditions apply
