Hi! I'm new to this forum, but I was looking for some guidance on a old Ford 5000 (1972) we have on our farm. The tractor won't lift its hydraulic arms and I am afraid that the hydraulic pump has gone bad. Is there a good way to test this theory? We have been using this tractor to pick up hay bales (using the back hydraulic arms) for at least 10-15 years. It was getting weaker and weaker the last few years until it gave up altogether. It has been sitting for the last 3 years and my dad and I recently got it back up and running. Any thoughts or suggestions? It is greatly appreciated!
