Husqvarna LC 451S Self-Propelled Lawnmower

  • Product Details

    The impressive Husqvarna LC 451S is a durable semi-professional petrol mower with self-propulsion, designed for part-time use. With a robust 51cm aluminium deck and excellent collection performance, it’s a fantastic model for those who need a mower as part of a home gardening business.

    Many machines are not designed for the rigours of cutting on a daily basis, but Husqvarna have a range of products which are specifically engineered for that purpose. This particular machine is designed for semi-professional use. Features which make this mower particularly suited a more regular use include the professional graded gear box with aluminium case transmission to endure frequent use over time. The handle bar can be folded down for storage and transportation.

    With a reliable Briggs & Stratton 750e DOV 161cc engine and a robust cast aluminium cutting deck designed for optimal collection performance, you can be sure that your machine will work when you need it to. The Husqvarna LC 451S has a sizeable 65 litre collection bag so you won’t need to constantly stop mowing to empty it out. Should you be working on less formal gardens, you could use the rear ejection function, or invest in the BioClip kit for mulching.

    Like many of the Husqvarna mowers, the user-friendly and ergonomic handle bars on the LC 451S can be set to two different heights for operator comfort. The collection bag features a dust blocking design which can be particularly useful when cutting drier grasses. The level at the back wheel control the height of the whole deck which can be really useful when each lawn you cut is different.

    Single speed self propulsion (4.1km/h) takes all the hard work out of mowing, making the LC 451S a fantastic option for the semi-professional user.

    About Husqvarna
    Believe it or not, Husqvarna did not start off by manufacturing any type of garden machinery at all. Instead they were established in 1689 as a weapons foundry supplying the Swedish Armed Forces. During the subsequent years, diverse and varied products have been produced, from sewing machines and cast iron kitchen equipment through to bicycles and motorbikes. It wasn't until 1959 that Husqvarna finally made its first chainsaws and engine-driven lawnmowers. The company's reputation for build quality and durability of product has never been in question. This is probably the reason for their line of professional petrol chainsaws being so popular with forestry workers across the globe.

    Husqvarna are not afraid to innovate either, introducing the robotic, solar powered Automower® in 1995 and continually looking to improve their existing products by listening to their customers. Jumping onto the grass recycling bandwagon, they also manufacture some of the best mulching lawnmowers available, incorporating Bioclip® technology into the vast majority of their petrol lawn mowers. Be left in no doubt, if you buy any product from the Husqvarna garden machinery stable, you will be buying into Swedish quality that is built to last.
