Hi Chuck, Hope you are doing fine. Old age has my wife and I surrounded on all sides. Stair lifts are coming Monday.
As far as how the two different fronts treats the seat of the pants, there is little difference. Another aspect of comfort is how the steering wheel treats the arms, there is a BIG difference.
For the tricycle when plowing across the field the steering wheel is a little aggravating. At the ends of the field the steering wheel can get really nasty.
When the tractor leans to the right because the right wheel is in the plow furrow, unlike the John Deere Roll-O-Matic, the right front tire of the DC tricycle carries much of the front weight. This tugs the steering wheel to the right. The operator has to keep tugging the steering wheel to the left. Over time the arms can get tired. Two hands on the steering wheel.
At the ends of the field, dropping the tricycle front into a plow furrow can make the steering wheel act very nasty.
Neither of these two situations bother the wide axles very much. The AWF especially is a one-handed-drive-like-a-dream even when plowing.
The steering situation, when plowing, is is one of the reasons my brother Carl converted his DC to look a D. None of my DCs rescued ended up even close to being original. Therefore, three the tricycles I rescued got converted to AWF. One got a standard wide axle.
