3-Point Hitch bouncing, bad, after repairs were made

[mtlane3795]

i recently had too take apart the valve body assembly on my l2250. after i put it all back together, the 3pt jumps up and down, sometimes violently. i cant seem to adjust it externally. i already took it back apart and changed some adjustments, it is a little better but not right. is there an easy way to get the adjustments right? or will this be a whole lotta trial and errors before i get this right?

I don't have the answer but my L3300 is doing the same thing when I lift my rear finish mower. I was hoping it was a relief valve but the service manual is pointing to the 3pt valve body.

I won't be much help, i can just say my Dad had a way of adjusting something on his ford jubilee when that happened. I know the systems are different but,:2cents:

I replaced all o-rings for the 3pt valve spoon and the lift cylinder. The bounce went awy and now if I leave the rear mower raised, it will not drift down ever after weeks.
