Thats seriously cool.
It gives the impression of a very early rover or cox tractor, strangly enough the appearance resembles my massey ferguson 35 on the farm....
On the cowling of the motor there will be a long string of numbers with model type and code with these we can work out when the engine was made and speculate on the age of the machine itself.
The engine itself looks to be a 5hp briggs and stratton, they are a good engine if they have been treated well
