The tractor models that are to be provided by John Deere are going to be either the 3035D or 3043D series that can be seen at the link (once at the site, select the 3 series) below:
The tractors are 4WD with manual transmission and a forward/reverse shuttle shift.
Let me know if you have any questions.
