[quote=&quot;Terry Buelow&quot;:nc4qmrn5]The mechanical lift on one of my RowCrop 60's occillates or moves up and down when it is in the forward position.  Almost like it is being bumped by a &quot;cam&quot;.  Return spring has been replaced and the lifts on three other 60's do not move after rotating, just this one.  Is there something that needs adjustment, repairs or ?  Ideas ?  Thanks in advance for help.[/quote:nc4qmrn5][b:nc4qmrn5]    
[/b:nc4qmrn5] I have never been into mine but my first guess would be that the foot lever  is not fully returning to neautral.  Possibly something keeping it from returning fully.  If I had a schematic I could be more definate.  R.Kerr, Central Point Or. 541-664-2734
