Hi Guys,
I am trying to problem shoot a transmission problem on a 7810. I havent seen it yet, it is my uncles. This tractor has the 'dual power' box between the clutch and main transmission. I have been told that when the engine is started and its put into gear, nothing happens.
Some things I observed when last using it: When driving along not necessarily under load, there was occassionally a shudder in the front wheels, more like a jerk and a scary noise as it appeared the front wheels were thrown into rotating forwards. I 'think' it wasnt in 4wd at the time?
Additionally, when the pto came under heavy load, the pto dropped out and stopped. This may be unrelated. I would add that also when under very heavy load smoke was observed coming from the back of the tractor, exiting somewhere near the top link. Again, maybe completely unrelated.
Any suggestions for problem shooting the transmission of power from engine to wheels is appreciated. It did have a new clutch 12 months ago.

Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
