Yes it is a very good lesson to be had you're lucky you didn't get hurt or thrown off the tractor I have an Allis Chalmers C and as you know that does not have frame rails it relies on the bellhousing and the front pedestal as the framing or the engine block it was at my Brothers one time and they went to pull start it not knowing the tractor was froze to the ground because it was winter and hook the chain to the front pedestal and broke the tractor at the bellhousing luckily it did not completely tear it in half but he had to find a new torque tube an engine block and also the expense of a gasket kit to put the engine back together
There is a salvage yard in south east Iowa that has lots of Farmall parts. It's called Franzen family tractors give them a call for parts if you don't already do business with them. They've had almost every part that I've ever needed.
