Energic Mototracteurs 712 petrol (1955/63).
The 712 Mototracteur models were rare, it is thought only some 200+ were produced from the 1955 model A (with model B starting in 1956). They initially used the same identification plaque as the 411 with the numeric notation 70***, and in 1956 the mototracteurs used their own identification plaque. The mototracteur were found to be difficult to manoeuvre, with poor weight distribution In the working environment – it was necessary to have additional weight/s added at the rear to enable this mototracteur to perform its basic functions. Staub, of the time, offered a better mototracteur alternative and the Energic mototracteur 712 was phased out. Later to be replaced with the extensive 4RM tractors, they were worthy competition to the Staub and other direct competitor ranges. (I have a record from 3/1963 from the factory with prices for the 712 range, which were for sale alongside the 4RM ranges).
Engine/Moteur. Single cylinder, air-cooled, four-stroke with enclosed Lateral valves (soupapes latérales). The 712 in petrol form develops 11cv. The same engine as in the 411 motoculteur and the 511 tractor of the time.
Lubrication. By constant circulation of oil held within the sump of the engine.
Cooling. One large aluminium fan is mounted at the front of the engine, running on ball bearings. This system draws air into the hood circulating around the engine, ensuring cooling. this system was tested in extremely high temperatures and proved effective.
Starting. By crank.
Air filter/Cleaner. Metallic element – (dependent upon the element that can be oil surface coated).
Gears. Box Bté S.G.D.G.The three-speed gearbox is built within the engine offering 6 forward and 3 reverse gears depending upon the options. this operates through a lever (lower left-hand side facing forward from the seat) giving low/high ratios 1/4, 3/6, 2/5. The right-hand lever operates in 3 positions, furthest toward the front of the mototracteur is reverse, centre is low speed and towards the rear is high speed.
Reverse. 3 speeds are available in reverse depending upon the options.
Carburettor. Zenith 26 TH.
Clutch. Multiple disc type built within with the gearbox immersed in oil, within the engine casing. This operated from a lever pulled up under the left-hand side of the steering wheel.
Exhaust/Silencer. Fitted in a frontal position right-hand side, away from the driver.
Steering. Executed by the upright steering wheel, direct shaft on to gears that rotate around a geared semi-circle connected to the rear section of the Mototracteur.
Wheels. Pneumatic front tyres 750 x 18 (Michelin CR or Dunlop T 32) and trailing small rear tyres 10 x 4. (branded as all-terrain). Nine additional overall widths are available; 64, 66, 68, 72.5, 74.5, 76.5, 81, 83 and 85 cms. (Wheel width is regular-able between 0.53m and 0.85 m (1.03m in some range lists of the time). These are obtained by altering the wheels into different positions. Differential blockage operated through a lever pushing forward to engage.
Brakes. Independent for each wheel.
Rear-wheel assembly with old stick roller bearings(awaiting cleaning).
Hitch. All implements are attached to a 3 metal bar rack system. Where you can attach implements such as ploughs, hoes etc., in many variable positions depending upon the type of work required. Careful use of the manual lift and weight allows the operator to alter and maintain the draft and other characteristics required to operate the implements at different depths and pressure.
Rear ratchet assembly for attachment bar.
Ploughing depth. Up to 12 ins (30,48 cms) dependent upon soil conditions.
Fuel consumption. 1 1/2 to 2 litres of fuel per hour dependent upon working conditions. The tank holds approx. 9 litres.
Throttle control. Operated from beneath the right-hand side of the steering wheel (while positioned facing forward).
Mototracteur articulation assembly.
Weight. 710 kgs, when fitted with wheel metal weights/masses, and the rack behind/arriere-train for implements.
Brakes. Independent on each wheel, operated from the near the steering wheel.
Dimensions. 3.47 m long with rack down, and 2.20 m with the implements rack vertical/up. 0.64 m to 0.84 m wide.
The price. In 1963 was 6910 francs.
Now for a rusty prospect, a bit of time, knowledge and it could be a runner!
