New to board, but not new to owning a bobcat. Have had my 95 853 for about 10 yrs. It has about 2800 hrs. Started leaking Hyd. oil a couple of yrs. ago. Its down in the depths under the seat & I can't find it. Will use about a qrt. a day & dribbles out the bottom. Steam cleaned it this fall & still can't find. Used it for snow this weekend & it was making a kind of screaming noise when it was under heavy load or heavy load & turning. We had alot of heavy snow. Am going to pull wheels, lift cab & try running it to find leak. Noise has me nervous. Have never changed or tightened belt that runs pump. Any thoughts would be appreciated. Anyhow, enjoy reading of this forum & hope to be of some help someday.
