Get through large-scale commercial felling jobs rapidly, comfortably and safely with the aggressively powerful Echo CS-501SX Petrol Chainsaw!

Supplying that power is a 3.45hp Echo air-cooled two-stroke engine that boasts a huge 50.2cc cylinder-displacement, and which incorporates Echo’s G-Force air pre-cleaner for superior component protection, and therefore rock-solid long-term reliability.

Stage-2 emission compliance provides a more pleasant working environment for the operator; a die-cast magnesium crankcase minimises weight and maximises durability.

Designed to be quick and easy to maintain, the Echo CS-501SX Petrol Chainsaw features an inboard clutch for simple cutting-gear removal/replacement, straightforward side chain tensioning and no-tools air filter access.

It has a rotating chain catcher and an inertia-activated chain brake for the best possible operator safety, and it’s fitted with a replaceable metal bumper spike, which ensures you’ll always be in full control.

Despite its high-powered engine, the Echo CS-501SX weighs-in at mere 4.7kg, making it one of the lightest professional-use saws available.

Other features of note include an anti-icing system for successful cold-weather operation; and a decompression valve, which takes all the work work out of getting the saw started.

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.
