The S421 PD has the same great features as the S421 HP, with the addition of power driven rear wheels. This takes away the effort of pushing the mower; simply pull the clutch lever and away you go. Release the lever and the wheels stop – it couldn’t be easier.

Power driven mowers have become very popular and in many cases, preferred to their hand propelled counterparts.

Powered by a Mountfield 100cc 4 stroke engine and with a 41cm/16″ cutting width, the S421 PD is ideal for small to medium sized lawns up to 40m x 40m.  The engine is easy to start, using a standard recoil rope system and will give many years of trouble-free mowing.

The 3-lever height adjustment offers 5 pre-set cutting positions from 25mm to 80mm, adjusting the height of cut is quick and simple.  The collector holds 60 litres of grass with a visual indicator to show when it is full.  The mower can also be used without the collector, if you wish to leave the cuttings.  Also included is a mulching plug, there is no need to collect the grass, you can recycle the grass clippings back into the lawn, saving you time, money and effort.

This great little mower is a joy to use and extremely economical to run.  With a robust steel chassis, powder coated in ‘Mountfield red’, it will give you many years of service and have small to medium sized lawns looking neat and tidy in no time.
