A LTHOUGH the Ferguson tractor C i has been used in an industrial capacity .in coal .yards„. docks,.quarries and in factories, there has never been an industrial version of it. . Such a model, restyled and equipped to suit that class of work is, however, now available. There are also two other new models, one an oil-engined version of the agricultural machine, and another which is referred to as an extra-narrow model.
Apart from its styling, the industrial model, in order to comply with legal
requirements, has two independent braking systems and is provided with horn and driving mirror. The hinged mudguards which give the driver full protection from mud at the speeds attained on the road, can be quickly detached to leave the tractor suitable for agricultural use. h is available with either a petrol or vaporizing-oil engine. The power unit in the oil-engined Ferguson has a capacity of 2,092 c,c. and runs on a compression ratio of 17 to 1. It has four cylinders with a bore of 313r, in., the stroke being 4 ins. At 2,000 r.p.m., the tractor develops approximately 25 belt h.p. The combustion chamber is of the FreemanSanders type and injection is on the indirect low-pressure system with a pneumatic gOvernor• for the fuel injec
tion pump. .
• me other features of the engine include renewable dry fineri; push-rodoperated overhead valves, three-bearing crankshaft, and duplex-chain drive to the camshaft. It is claimed that a top overhaul will not be needed before 1,000 hours running, and that the unit is characterized by its quiet, smooth running.
With the exception of the engine, the tractor specification follows that of the current production.
Although the standard Ferguson tractor has only a 3 ft. 6 in. minimum track, the demand for a model even narrower has been met with one having a minimum track width of 3 ft. 1 in. front, and 2 ft. 8 in. rear.
Smaller wheels have lowered the tractor by 2 ins., thus stability is retained despite the narrow track. To maintain this feature when using long overhung implements, extra front-wheel weights (90 lb.) are provided. It should be pointed out that this model 'hilly retains the advantages of the Ferguson hydraulic system.
A number of progressive modifications has been introduced on all models. For instance, the electrical system is now 12 volt and the starter motor is of improved design. The engine govern°, and throttle have been modified to give increased sensitivity, and the air intake is now carried on the dashboard.
Two additional oil-pressure take-off points have been incorporated in the hydraulic top cover. This extends the range of potential usefulness of the oil pressure to operate new implements. New floating-cam double-action brakes, giving equal effect both forward and reverse, form yet another improved feature. Extra bolts in the gearbox casing add to rigidity of the main structure.
