Description
The Mountfield S421 PD Lawn Mower 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 up 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 over the last few years and we now sell more of them than hand propelled models.
Powered by a Mountfield ST140 139cc engine with DSC transmission and with a 41cm/16″ cutting width, the Mountfield S421 PD is a 4-in-1 mower is extremely versatile and allows you to collect the grass clippings in the 60 litre grass collector or you can choose to mulch, rear or side discharge the cut grass depending on your needs. Mulching the grass can save time, money and effort; when the mulching plug is fitted the finely cut grass clippings are deposited back onto the ground as a nitrogen-rich mulch which is recycled back into the lawn as a natural fertiliser. As no grass cuttings are collected there is no need to stop to empty the grass collector, saving you around 30{d09b12be51a7a6a48787a7bc3312473190ccc1fdbfe07795db7f7cb91fdca1cd} of the usual time taken to cut your
Height of cut can easily be adjusted with a single lever through 6 pre-set cutting positions from 22mm to 65mm, and cleaning after use is facilitated using a hose connection fitted to the chassis.

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 30m x 30m looking neat and tidy in no time.
