Combining a rugged tubular-steel frame with a high-capacity 460cc four-stroke OHV motor generating a maximum power output of 8500w, the Feider FG8500ES is suitable for intensive, heavy-duty use in agriculture, horticulture and building.

It might be powerful enough to handle demanding equipment such as construction gear, but the versatile Feider FG8500ES Open-Frame Petrol Generator can, thanks to its AVR alternator, also be used with voltage-sensitive equipment.

Great for situations where keeping quiet is essential, the Feider FG8500ES Open-Frame Petrol Generator benefits from a design-optimised muffler, which keeps noise levels down to just 74 dB(A) at seven metres.

Feider’s reassuring two-year warranty serves to demonstrate the build-quality of your potential purchase; their provision of a positively cavernous 25-litre fuel tank means you’ll enjoy extended runtimes of up to nine hours at 50% power.

Also featured is an auto shutdown system, which protects key parts, should the oil level run too low; twin transport wheels, which make what is a hefty unit easy to shift from worksite to worksite; and an electric starter for effortless, zero-hassle ignition.

The output sockets on this model are as follows:

– 1 x 230v/16amp single-phase AC.

– 1 x 400v/32amp three-phase AC.

– 1 x 12v/8.3amp DC.

If you need four-stroke engine oil, you’ll find it here.

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.
