When the very early prototypes of the new 500 ( to be series 511) tractors where at the drawing board stages. The 409 9cv motoculteur engine was fitted to a 500 chassis and it was found to be significantly under powered for the weight of the tractor. Ets Patissier ran trials with various engine sizes. So this project 509, 9cv tractor (moteur used in the 409 motoculteur) was shelved in favor of the larger 11cv petrol Patissier engine fitted to the 511, 1949/50. Production models appearing in 1950, and version 2 in 1955.


Engine. Single cylinder Patissier engine, 9cv, 500cm3, air cooled, four stroke with enclosed Lateral valves (soupapes latérales).

Lubrication. By constant circulation of oil held within the sump of the engine, 3.5 liters. The circulation by pumped pressure also from from crankcase compression. (Graissage par pompe incorporée).

Cooling. One large aluminium fan which 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 extreme high temperatures and proved effective. (Refroidissement par air forcé (ventilateur puissant).

Starting. By hand crank, either direct on to the motor, or via the multiplicateur. Both located at the front of the engine.

Air filter/Cleaner. Metallic element – (dependent upon the element that can be oil surface coated)..

Steering. By worm gear.

Gears. The three speed gear box is built within the engine offering 2 variations either 3 forward and 1 reverse or 6 forward and 3 reverse gears.12 gears where obtainable as a optional extra. Differential lockable.

Reverse. 3 speeds are available in reverse depending upon the options.

Clutch. Multiple disc type immersed in oil, within the chassis casing. PTO; front (revolving at the speed of the engine), side and rear (turning between 125 and 1800 rp/m). Clutch engagement for the PTO systems. ( PTO rear and side options). Embrayage est du type à disques multiples baignat dans l’huile.

Exhaust/Silencer. Fitted in a frontal position, away from the driver.

Magneto. Either Morel or Lavalette type. (Allumage par magnéto à déclic, assurant un démarrage instantanné).

Wheels. 3 options; Pneumatic Tyre wheels front 400 x 15 and 750 x 18 Rear. Blockage independent for each wheel. Wheel width is regular-able between in 9 stages between 0.53m and 1.15m. These widths are obtained by altering the wheels into different positions.

Brakes. On each rear wheel shoe type, pressure by manual foot pedals, independent that can be linked.

Hitch. 3 point lift manual, automatic or hydraulic type Dynabloc.(depending upon the option selected).Breveté system S.G.D.G. (patented in France and the UK) articulated strengthened with universal fitment to all ancillary equipment. Enabling the adjustment of draft and other characteristics required to operate the implements at different depths.The Dynabloc automatic was tested some 200 000, lifting 250kgs, without lost of lift capability.
Ploughing depth. Up to 12 ins (30,48 cms) dependent upon soil conditions.

Fuel consumption. 1 1/4 to 2 liters of fuel per hour dependent upon working conditions. the tank holds approx.17 liters.(Réservoir de carburant).

Weight. 600+kgs

Diamentions. Length 2.2m, width .85m and hieght to steering wheel 1.15m. (Longueur totale 2 200 mm, Largeur de 850, à 1 150 mm Hauteur au volant).
