This heavy-duty rough-cut mower from Orec eschews the conventional rotary blade, and instead employs rotor-mounted flail blades, which will take long grass, overgrown brush and thick scrub in their stride!

Powering the rotor on the Orec HR531 Flail Mower is a 196cc Honda GX200-Series engine that packs an impressive 5.8hp punch, and which boasts a transistorised ignition system for dependable start-up at each time of asking.

Honda’s OHV technology cuts operating temperature, which in turn extends motor life; a substantial, 3.1-litre-capacity petrol tank works with the engine’s efficiency optimised design to minimise the frequency and number of refuelling stops.

Thanks to its deep-tread pneumatic tyres, independently disengageable wheel drive, wide stance and low centre of gravity, the Orec HR531 Flail Mower is ideal for slope and bank work, and offers excellent manoeuvrability on difficult terrain.

Highly versatile and able to be adapted to suit a variety of conditions, the Orec HR531 boasts a four-speed transmission, and features blade adjustment from 50mm all the way up to 100mm.

Also important on this 52cm model is the vertically adjustable handlebar, which can be made comfortable for operators of any height.

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.
