[QUOTE="VAFarmUse, post: 108719, member: 16894"] Right side is smooth and drive fine forward or reverse. When I move the left stick (especially to turn) either forward or reverse, I notice a decent whine, along with a lack of power. What is somewhat odd to me is that if I am moving both sticks at the same time, the whining is almost non-existent, but at soon as I put more load on the left side, it starts to whine again. I can definitely feel it is straining, and it almost feels like the hyd flow isnt as good on that side. the right side seems fine (for a 30 year old machine) and turns with relative ease, especially compared to the left side. Any thoughts on what this is? I suspect left drive motor, but hoping it is a seal or valve that can be replaced. Havent done much with the hyd system yet, other than add some oil to the tank and to the lower drive reservoir. I know I need to start with a fresh filter, but I dont think thats the issue, since only one side is acting up. thanks in advance for the input.
