Top Speed75mph

The Land Rover Defender Agricultural conversion kit has been designed down to a price to give a farmer or landowner everything they need in an everyday utilitarian vehicle and an average investment payback of 4 years or less.  The electric conversion kit was developed in partnership with Innovate UK, Cardiff University and Worthy Farm (host to the Glastonbury Festival), where our electric agricultural Defenders have been working since November 2020.

The drop-in kit suits all Land Rover 90s and 110s pre-1989, and also works well with 200tdi and 300tdi vehicles (1989-1998) though with slightly reduced torque compared to the original.

The kit is designed to be fitted by the landowner’s local garage. It is simple but performs well, including taking trailers into situations where the original vehicle would have stalled or burnt out the clutch.  It includes a 52kWh battery pack, which is more than enough for average farm use – simply plug it in to charge every night. 

“They’re good little Land Rovers.  We use them on a daily basis and they do everything we want them to do.  Financially they’re great: each one saves about £6,000 a year in fuel plus there’s no road tax and less maintenance.  There’s no worrying about driving to a petrol station – just unplug and off you go – and on cold frosty mornings, there’s a little switch and you have instant heat.”

Electric Defender Kit Details

The conversion is a simple one, with a low-voltage Hyper9 electric motor replacing the diesel engine, and driving the 4WD system through the original gearbox.  Electric vacuum pump, power steering and heating are added, together with LED lighting.  The 52kWh battery pack simply lifts into the engine bay.  Range is about 100 miles on road, and further off-road – though of course it depends on hilliness, trailer towing, etc.  The charge point is located in what was the carburettor air intake.  The charging system is air-cooled and as standard will not deal with rivers deeper than the driver’s footwell.

Electronic “engine braking” for controlled descent of off-road hills is provided by means of a 3-position rocker switch.  This is an important feature for towing!

Overall it is a great addition to the farm:

It improves sustainability – reducing carbon emissions, and recycling instead of replacing a useful farm vehicle

  • It saves money: experience to date shows a 4-year payback (with red diesel prices at 80p/litre) because of the lower fuel price and lower fuel usage
  • It excels at short trips – quiet and efficient when a diesel engine would be cold and inefficient
  • When the vehicle is stationary it is not burning fuel – working Land Rovers consume a large portion of their overall fuel burn when idling
  • The heater comes on instantly – very popular with the farm workers on cold mornings
  • No trips to the petrol station – very popular with farm managers!
  • It makes towing easy
  • It’s quiet and nippy – e.g. it’s great for nipping round behind the cows when you need to move them

In short, your converted electric Defender will do everything you want it to do on the farm and around the locale, quietly and with spirit, but it is not built for motorway cruising or long road trips – the motor is air cooled and will reduce power if run at maximum output for extended periods or in hot countries.  If you want to cruise or you live somewhere hot, look at our water-cooled Land Rover Defender kits.
