When I purchased this tractor it was a but of a mess needing tires and a steering box and a paint job. The gas motor is very solid using no oil all these years and getting about as good fuel consumption as can be expected from a gas engine.
I installed an international 1500 loader about ten years ago along with power steering. It is a solid tractor that is good with a loader (with a heavy counter-weight).
I have spent too many hours mowing with it as well.
The gear box with its square cut gears is quite solid but bulky by today's standards, shifting gears usually requires stopping. It's found in many models from the period with eight speeds that give plenty of range.
Like any old machine you have to keep up with repairs but it is a remarkably reliable little English tractor that is used year-round. I'm a pretty good shade tree mechanic so I don't spend much on repairs but some of the problems with any old tractors can add up quick at the local shop.
