Hello everyone im new to the site, I got a 175c thats been sitting for about 7 years now. Its foot pedal steer and machine is low hours only packed silage with it. Anyhow we went to try and get it to move to help clear some land. The motor fired right up with a shot of ether after sitting so long. But i cannot get it to move at all i have checked all fluids and topped them off. When i put in gear it doesnt move or even try to, i took floorboard out and noticed that the driveline is spinning when in neutral and in gear. I knew something was wrong when every gauge moved except the clutch pressure. I got all floor plates out the way and do not see any leaks or anything. However when i take the test port plug out i am getting lots of air and very little fluid. I had the plug out for maybe 5 mins and still no change. Idk which test port i opened considering the plate doesnt have any letters or marks on it. What do u guys think to check 1st? Any help would be appreciated! Also the 4 in 1 bucket and loader has full power and works like it should.
