|This is a Chamberlain Champion tractor, built in Australia, in the late 50's and early 60's.|
It had a Perkins 4-270D diesel engine which gave, I think, about 52 hp at the flywheel and about 45 hp at the drawbar. Inside that cab you would find a full width bench seat for TWO people, the driver sitting right over to the right side of the seat. As with all agricultural Chamberlain tractors that I ever saw, it had a transverse leaf spring on the front axle which vastly improved the ride over ploughed fields or other rough ground.
The first model of Champion, the 6G, had a main gearbox with 3 speeds forward and one reverse and a two-speed range gearbox behind it,giving 6 forward gears and two reverse. The second model, the 9G, had a 3-speed range box, giving it 9 forward and 3 reverse gears. Both models had a top road speed of 27 mph. The tractor shown here is a 9G.
One of these tractors, known as 'Tail-end Charlie', went around Australia 1 1/2 times with an around-Australia car arlly that was held each year back in those times. This one had a modified gearbox that gave it a top speed of 50 mph. Its main purpose was, I guess, advertising, but it also towed quite a few broken-down rally cars to the next town as it went.
The cable leading up from the engine to the back of the dash panel is for the tachometer.
