They are a tank!!!! The engine is unstoppable, can suffer from cavitation like all Fords of that era. Check for diesel in the sump, unlike most of the range, the Minimec pump is lubricated by engine oil from the engine and, if it has a leak it can fill the sump with quite interesting consequences.
Pulling the stop or switching off the engine does not work when diesel is getting by the pistons.
Dual Power is great but can suffer from warped plates if used as an engine brake, dropping from Hi to Low to slow down with a load on the road.
Brakes can give problems if the correct oil is not used in the hydraulic cylinders and if the oil is not changed regularly in the back end. Filters need to be changed too if you are doing a lot of trailer work on the road.
Hydraulics do not have the best lift capacity in their class but you have to remember that she was designed to work with semi-mounted or trailed equipment.
She perhaps would not be my choice for a tractor that was doing limited light work as you will soon find she will be slobbering oil out of the exhaust and possibly glazing the bores but if you were going to put it into hard work or heavy pulling then there are few better tractors on the market. You will also need heavy lifting gear if you are going to work on them too.
