Whether it’s pruning, lopping, logging, firewood prep or DIY, this versatile and easy to use petrol chainsaw from MTD can handle them all.

Driving the MTD GCS4100/40 Petrol Chainsaw is a high-torque 40cc (1.7hp) MTD two-stroke engine that employs an aluminium crankcase and cylinder for rust resistance and weight reduction, and which has a roomy 0.31-litre fuel tank that will see you complete the job without too many tiresome interruptions for refuelling.

A fuel primer makes the engine easy to start from cold; a decompression valve means ignition can be achieved with the gentlest of pulls on the starter rope.

The MTD GCS4100/40 Petrol Chainsaw is equipped with an anti-vibration handle and weighs only 4.5kg; a combination that facilitates long periods of fatigue-free use.

It offers convenient side chain-tensioning, so you’ll find making in-the-field adjustments is a fast, hassle-free operation, and it features an automatic chain oiler, which not only keeps the high-grade Oregon cutting gear in tip-top condition, but also delivers a super-smooth cut.

Safety features include a cutter guard, which protects the operator, should the chain become detached from its rail; and a fast acting, inertia-triggered chain brake, which stops the chain immediately in the unlikely event the saw ‘kicks back’.

Shipping Info

Shipping Info

If you’re buying a boxed product, we aim to get your order delivered next working day – UK mainland where possible.

If you’re buying a tractor or ride-on mower – a special order item – it could be slightly longer, as we need to PDI the machine.

We do try and van-deliver these machines if we can, as this gives us a chance to demonstrate the product, and to ensure you’re happy and confident with your purchase.

If we can’t van-deliver your machine, as you’re out of our local delivery area, the tractor will be sent on a pallet via a courage company. They will then contact you directly to book a specific day and time that suits you.
