Other Mechanical Horses
As well as the highly successful Scammells, other companies also produced small 3 and 4 wheeled vehicles with a Mechanical Horse type coupling. Karrier developed their Cob tractor unit, fitting it with a coupling which was compatible with the Scammell and this was a popular choice. Jensen Motors, the well known bodybuilders, produced a small 4-wheel tractor unit called the Jen Tug. Ford also produced a tractor unit called the Tug which was based on their 8hp Model Y cars, but whilst this was a 3-wheeled vehicle it wasn't fitted with an automatic coupling. A number of companies also offered larger 4-wheeled tractor units equipped with a Mechanical Horse type coupling and a few examples of these are included in the section below:

Dennis ‘Horla’

'Horla' was the model name given by Dennis Lorries to the post war PAX model when supplied in normal form as an articulated tractor. These vehicles were developed from the pre-war "ACE" or "Flying Pig" and were fitted with that models petrol engine. Perkins diesels were an option and the vehicle illustrated, made in the early 1950's, is fitted with their P6 engine and Scammell's 6 ton coupling gear. It was an unusual vehicle to be fitted with the Scammell coupling and it would be interesting to know how many were produced
FAR (Chenard-Walcker)

FAR built Scammell Mechanical Horses under licence in France; early versions were fitted with Citroen engines as used in the Traction Avant, whilst later ones were developed separately and incorporated features such as a tilting cab and a braked front wheel! The 1938 example seen here is owned by the Association des Amis du Musee du Poids Lourd and was photographed during a visit by The Mechanical Horse Club in May 1986. A good collection of FAR images can be seen here.
Karrier Bantam
The Karrier Bantam was introduced in the
mid 1930's as a lorry for loads of up to 2 tons. Its small wheels gave it a low
loading height. Initially fitted with a 9hp engine, it was soon to get an 18hp
unit from the contemporary Rootes Humber car range. In 1950 the cab design was
changed and the Bantam was offered with a Perkins diesel engine. In articulated
tractor form the Karrier was very popular with British Railways and other
parcels carriers and continued in production until 1970 when it was fitted with
the Leyland OE160 engine, similar to that powering the Scammell Townsman and
Ferguson tractors. It is fitted with Karrier's own 3 ton coupling gear that was
fully compatible with the Scammell version. The example shown being recovered after many years of
storage on a Sussex farm is being restored by the Clubs Spares
Register.
Reliant Ant
The last flowering of the Mechanical Horse (three wheeled) concept is by Reliant who
with Dunn BTB produced an articulated version of their TW9 (Three wheeler)
3/4 ton pick up. Several members of the club have these vehicles and
the club have welcomed them for their contribution to the preservation and
restoration of these classic vehicles. Most are of the pick up truck variety,
but one artic unit survives, pictured below.
The TW9 was produced by
Reliant from the late 1960s onward and is still being made overseas. The design
was taken on by Dunn BTB and called the ANT. A lot of the production went abroad, especially to
Greece and Turkey The engine is Reliant's
own 750cc aluminium unit with a 4 speed gearbox. The chassis is a pressed steel
frame with tubular cross members. The truck has a payload of 16 Cwts, does
60mph and around 35 miles per gallon. The cab is a fibreglass moulding. A variety
of bodies were offered by various different coachbuilders and included dustcarts,
tower wagons, tippers and street washers/gully cleaners and suckers as well as
the pick up truck. Quite a lot of the vehicles were milk floats or were used by
council Parks & Gardens Departments. With their fibreglass
cab and sturdy chassis construction, these vehicles are fairly easy to restore.
parts are still available from Reliant parts or from your local motor factor. A
lot of proprietary parts were used by Reliant - for example the front brakes are
from the Ford Escort and the rear ones from a Ford Capri. The engine is the same as that
used in the contemporary Regal and the later 850cc Robin engine can be easily fitted. The trucks are quite
nippy and economical and make excellent runabouts. The Mechanical Horse
Club has links with the Reliant Club, especially in the Essex area as their Chairman
and Club Historian, Bob Neale, is a member of both clubs.
