91" :thumbsup: Ah, you got this in the bag! But...go slow the first time in. :laughing:

I sure hope so cause it would sure be tough letting the air out of the tires every time I need to put it in the garage :laughing:

You need a backhoe. My backhoe drops the tractor almost 2". Tell your wife its either a backhoe or a major refit to the garage...:laughing:

Haven't checked lately but there were two sizes of R4 tires offered with the 3X20 when I ordered my 3720 cab tractor. I chose the smaller size just so it would fit in the garage doorway. I'm sure the smaller tires will work for you ........... don't know about the larger R4 tires.

Mine's in the shop now, so I can't measure. The 3x20 series offers two different R4s.
(a) four ply; 27x8.50-15 front, 43x16.00-20 rear
(b) six ply; 25x8.50-14 front, 15-19.5 rear
Given those numbers, the 4-ply R4s should make the 3x20 cab model a little taller than the heavier duty 6-ply option.

This is more info to add to my note above. Distance from floor to top of cab roof is 88.5 inches. My 3720 has the Galaxy R4 6-ply tires.
Rear: 15-19.5 Front: 25x8.50-14

I wonder how much difference there is in the smaller R4's compared to the larger R4's....

According to the Galaxy website ATG - Alliance Tire Group here are the differences in rear tire sizes.

15-19.5 ===> 40.0 inches O.D.

43x16.00-20 ===> 42.6 inches O.D. (tractor height will be half difference or 1.3 inch higher)
