Around 1958, this unusual looking vehicle conversion was launched by James A Cuthbertson, of Biggar, in Scotland. It was designed to go further in adverse off-road conditions than the conventional Land Rover.

In most cases, a standard Series II long wheelbase Land-Rover minus its wheels was dropped onto a sub-frame, and a track fixed around bogeys at each corner with a sprocket that replaces the Land Rover’s road wheels. The front tracks are steerable in the conventional way, the tracks turn as a whole for steering - aided by substantial power steering driven from the engine crankshaft pulley. However when 4-wheel drive is engaged, each track is powered at each corner with a different motion. This stops the side to side scrubbing of tracks when turning which tends to happen on conventional tracked vehicles.

The main advantage of this conversion was that it greatly reduced the vehicle's ground pressure, making it ideal for marshy and wet ground. The main problem was that it was poor at climbing 'steps' (i.e. banks) or over obstacles because the tracks lack the front "ramp" of typical tank tracks. The tracks would tend to spin if the Rover hit a steep bank whilst traversing marshy land. The height was both an advantage and a disadvantage. Ground clearance was increased, but stability was reduced.

Of the estimated 15 examples made, the last of these was thought to have been built around 1972, although the two pictures shown below may blow that idea out of the water!

These pictures were taken on Skye in 1983 by Richard Camidge. They show a short wheelbase Series III Cuthbertson style conversion on a 1976/77 R UK registration plate, painted in the British Telecom livery of the time. The vehicle was first registered in Inverness on the 1st December 1976 and was a 2286cc petrol model, according to DVLA records. The tracks and subframe appear to have been further developed over earlier examples, although this may indicate a different manufacturer. Any information on this conversion would be very much appreciated.

Today, the Cuthbertson company continues to manufacture special vehicles, mainly building snowploughs and road gritters.

Looking at your site I came across Cuthbertson Landrover reg 76aa75. I have to tell you I was the driver of this vehicle in 1962 and we had a sister one but the number escapes me. I have an original photo, different angle. I drove it on Holbeach bombing range in Lincolnshire and I remember going on a special course to get a track laying vehicle license. I am 72 now and was on 5131 Bomb Disposal work, The problem with this vehicle and it happened to me, It had a long draw bar at the front and this was to enable it when towed was so the tow rope cleared the front tracks. We cut it off with OXY. We did this because as we went into a deep dyke and tried to drive it out, the tow bar fouled the opposite ditch and as I accelerated it put pressure on the half shafts and - you guessed it - BANG the half shafts broke. Incidentally, this vehicle replaced two worn out Bren Gun carriers.
