Mountfield 1643H-SD

Tax included
The Mountfield 1643H-SD side discharge lawn & garden tractor offers the ideal solution for those of you who do not wish to cut and collect the grass cuttings. The 108cm cutting deck is built for tackling larger lawn and mowing areas of up to 3.5 acres.

In tall growth conditions the side discharge mode neatly cuts and spreads the grass so it can be left to wilt naturally. For areas that are being cut on a more regular basis the mulching function cuts and re-cuts the grass into tiny particles that are blown back onto the ground where they disappear into the turf, returning valuable nutrients to the soil.

Powered by a Stiga ST 550, the 1643H SD tractor has a hydrostatic transmission with a reverse gear. A hydrostatic transmission is similar in many ways to the gearbox on an automatic car, forward and reverse speeds are infinitely variable. To move forward you simply press the forward pedal and the more firmly you press the faster you will go. For reverse press the reverse pedal, you can change from forward to reverse instantly so manoeuvrability is fantastic.

The Mountfield 1643 H-SD is fitted with a 108cm/43in working width cutter deck with side discharge or mulching options. The cutting heights on the deck are easily adjusted into 7 positions from 25 – 80mm.

This model comes complete with a tow bar and mulching kit as standard. Additional features include headlights, washing link and front bumper.
