I bought the cylinder from the Surplus Center

There is no problems with creeping

 I have it on a Deere 8200,total travel is a round 14-16" @ pin(i think?)

This is the third or forth season i used it.So I don't remember the spec's


I build one for a neighbor that doesn't use any more that will fit any Deere from 8X00-8X20 that he may have to sell???

Thanks for the interest!!
