Description:
1.0.0.1
Scale has been adjusted to that of the IH 1066 which were very similar in size so the scale should be correct now.
1.0.0.2
The cab has been replaced. 
A work in PROGRESS. We are hoping to finish soon. Basic functions work A.T.M.. The normal trailer hitch does work. The three point hitch does not work A.T.M.. The steering wheel is still being developed so it has a place holder for now. The front wheels turn but the front axle is still being worked on so they turn but not 100% on the axle as they should.
