Larger cut, featured packed self-propelled Webb petrol lawn mower with 4 cutting functions.

The Webb Supreme R21HW is a 4 wheel rotary lawnmower with a 21 inch / 53cm cutting width. The R21 HW has 4 mowing options offering collection, rear discharge, side discharge and mulching.

When fitted at the rear of the lawn mower the plug allows the grass clippings to be mulched into tiny pieces which are then blown back onto the ground. The nutrient rich particles are re-absorbed for a healthier lawn. The side discharge option lets you cut longer grass areas and then leave the clippings to wilt back naturally.

Driven by the Briggs & Stratton 675 ReadyStart engine it has a power capacity of 190cc. Built on a steel deck the Webb R21HW has high rear wheels which allow the machine to be used in longer grass areas and help with manoeuvring. Suitable for most types of lawn and garden area up to 50m x 50m in size. The addition of the single speed power drive enables the user to mow a larger area quicker and without the fatigue associated with hand-propelled / push mowers.

The self-propelled R21HW has 7 cutting height positions adjusted via a single lever. Additional features include the 70 litre grass collector, soft grip handle and ball bearing wheels.
