That frame design is not quite what I think of when I picture articulating equipment.
I think the $3800 price is going to be a lot of light weight pieces and some Heavy weight maintenance problems...
If you feel you really Need an articulating tractor... Look at the Ventrac,
Articulation can be a great feature, and lends to a very versatile machine, but I think they have missed it on this one...
I'm very curious... what advantage do you see in this particular "articulation Feature"?
I do like a front deck mower... But this particular arrangement, with 2 wheel drive system looks lacking.
If you do get it, Post a lot of pictures as there is Not very much coverage on this lawn mower... KennyV
