Hydraulic Cylinder

[Cub 61]

I was moving some dirt this weekend and when my blade is down and i go over a mound of dirt or a high spot the blade raises and pushes the cylinder back to retracted position. Is this suposed to happen? If not, what do I do? Thanks.

First What piston? Aux lift, hydro lift? Neither should. If it's a aux hydro lift are you sure the rock shaft is not riding back up? If it's a on board hydro lift do you have a lock out pin installed?

If it's the lift cylinder you are talking about, it's just the rockshaft floating. You need to install the float lockout pin or bolt (depending on what model tractor you have) so that the blade has down pressure for moving dirt.

I have a 149, wherecould I get the pin or bolt, and how do I install it?

I got it figured out. Thanks for all the help guys. When I use my plow, tiller, and disk do I/ have to change it back so it can float?

I tried it out with the lock pin in and it is still floating.

Anyway of getting us some pictures of the float pin setup and your blade setup?

Here is a pic of the lock pin in.

Very carefully operate it without the tunnel cover as you were and see if it's actually the cylinder or something else. It may be that you have a broken spirol pin in the rockshaft but it's hard to tell without seeing what's going on.
