The Mountfield 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, it's as simple as that. Power driven mowers have become very popular over the last few years and we now sell more if they then hand propelled mowers.

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

This mower also has 5 different pre-set cutting options from 25mm to 80mm using the 3 lever height adjustment making the height adjustment quick and simple. The 60-litre grass collector also has a visual indicator to show when it needs emptying. Also included is a mulching plug so there is no need to collect the grass in you don't want to.

This is a great little mower with a robust steel chassis powder coats on 'Mountfield Red', it will give you many years of service and makes you lawns looking spick and span in no time.
