Please don't beat me up too bad, I just inherited this piece of equipment! LOL All the blade controls on my D5M LGP are very week and slow. The lift cylinder on the left side has a small leak not nearly bad enough to cause this issue. The dozer runs and drives just fine and only has 4000 hours on it. With that said it has been sitting for a couple years and only started once a month. It's a farm use only piece of equipment.
When did you change hyd filters last? Hyd oil full?
