Tractor SAM C-330 (based on Ursus C-330)

[Vermes]

This tractor is based on Ursus C-330.
Main parts:

• motor from C-330
• gearbox from Star 28/29
• rpm reducer
• IFA bridge w50
• wheels: read 16'', front 28'' from C330
• front axle from Star 28/29
• fenders and bonnet from C330
• cabin – self made
• steering from Star 28/29

the frame was made of channel section 120, bolted to the engine (rigidly), which is connected to the gearbox via orifice. Gearbox and regulator are connected by a telescopic hinge shaft. Regulator is directly connected to Ify w50 bridge (a bridge, which has a final drives that do not increase the ground clearance under the tractor and further, reduce the structure). Gear reducer is so calculated that in second gear (Star gearbox) total ratio of the tractor was the same as the C330 in fourth gear. Surprisingly, also three highlights (with five in the C330) cooperate, four is slightly faster (than six), and on five it is driving about 30 km/h. The tractor has a lift and PTO shaft. The hydraulic pump drive was taken from the snap from the gearbox. The hydraulic pump was from t-25, the distributor and the actuator C330. The tractor is a thorough rework, the original version had S60 engine, elements from Star, however, the Star bridge didn't work well in the difficult mountainous terrain. Star half-shafts didn't withstand the torque C330 and spoiled even a single, so it was changed to bridge of Ify. PTO shaft has its own switching. The electrical system was made to the schema model C330, also has a connecting bar (to the rear fenders and bonnet) from Fiat 126p and relays to headlights. Hydraulic brakes at the brake pump were from uaz with possibility to cut-off any rear wheel.
