I've got a 1961 John Deere 2010. First let me thank all the folks that responded to my previous messages on different topics. Lots of great help to get my tractor running. Problem now: my tractor set up for about a year or so outside but covered. the hydraulic lift was up during the time it set up. I put Hydraulic fluid in (2 gallons) till it was full. i let the lift down but it would not come back up. Once i ran it for about 15 minutes--sitting still--i checked the hydraulic fluid but it looked a little milky--i guess water got in. So i know i need to change the fluid a few times. Any thoughts on my lift problem I would appreciate it. thanks
