Using a traditional cylinder mower is not only good for the environment but it's good for grass too. The steel 5 blade rotates and cuts in a scissor action leaving a superior cut to a rotary mower blade. This cutting action also causes minimal damage to the grass blades which encourages healthy growth and a luscious green lawn. Cylinder mowers leave the best finish on shorter grass and we would recommend cutting the lawn a few times per week for the best finish.the cobra hm381 has a 38cm 15” cutting width and is lightweight at only 8.5kg. Suited to smaller lawns the mower has a 5 bladed cylinder and a fabric grass bag that clips easily at the rear of the mower.there are 4 cutting heights ranging from 13mm to 38mm which are adjusted, tool free using the pins either side of the blade. The hm381 is supplied with a rear roller for creating a traditional striped lawn, this also allows you to cut close to borders with the rear roller supporting the mower as you cut.specificationsmower type cylindercutting width 15 38cmcutting heights 4 from 13 38mmcylinder 5 bladedrear roller yesfabric grass bag yesweight 8.5kgwarranty 2 year domestic
