Planting with a 9560RT with a DB66, I am planting over one row on each track and the track is perfectly centered over the row so as the tread bars don't even contact the row.  Next year will be my first year with it so I am hoping it will work good as planned.

What sucks though is it is also used as a grain cart tractor and tillage tractor in the late fall like now.  You can not turn with it at all!  It is the worst tillage tractor ever (grain cart too) I feel sorry for you people that are hung up on the 2 track system, If you think that is God's gift to tractors please go drive a Quad Trac once.  I have a 550 Quad I run alongside the RT and I had to park the RT and tell the guy to go home, WORTHLESS! I am thinking of trading to a row trac but they are pricey.  I hope it will be better on the planter, I rented a 8370RT last spring to plant 2 quarters and loved it and tried to purchase it but end up with the 9560RT cheaper with less hours (now I know why)!
