Chris, there is a 8 x 10" tube axle member welded in line with the hub so we can not do the oscillating tandem approach with smaller tires. We have done that on some units in the past and it works well in its place. The large single R 380-46 tire however works very well. I think we will try the track unit on a field machine, and also offer an 18" wide tire as an option. At first we were very enthusiastic about the track unit. It would bolt on very nicely and offers far greater load capacity than either 14 or 18" tire. We will be very careful before we put many of these out.

Wilrich showed a new bar with this same track unit at Big Iron last month.

I appreciate everyone's input here.
