Deere 3320/3520 Cab owners

Timberman444 · Aug 28, 2009

I think its time to upgrade the 2320 to a 3320 or 3520 cab model with loader, was first thinking maybe of getting a Kubota B3030 cab due to its smaller size and lighter weight, but was quickly talked out of it due to it being so unstable/top heavy and plus I'd really like to stay with a green paint. The following measurements I need to know will be for a tractor with R4 tires; what is the total height of the tractor from ground to top of cab, also what is the outside width of rear tires in the wide position. Would you guys recommend loading the rear tires for extra weight down low to help counter balance the cab and how much more weight does the loaded tires add to the total weight.

There are two R4 tire size options for the 3x20 series which will affect width, height, and liquid tire weight. Click below to see tire options.

I have the 3720 cab tractor with the smaller R4 tires and it just fits in my overhead doors (1-2 inches to spare). Not sure of barn door height - will have to measure.

From a JD brochure and maual. The cabbed 3x20 weighs 3,570 lbs. Height with R1 tires is 89.4".
Width with R1 tires is 52.4" min and 68.4" max.
Width with standard 15.00-19.5 R4 is 57.3" min and 58.9" max.
Width with larger 43x16.00-20 R4 is 58.1" min and 59.7" max.

The R4 tires will make the tractor sit a few inches shorter than the R1 tires.
IMO, the R4 tires make the tractor seem narrow and it always felt a little unstable on slopes. The R1 tires can be set considerably wider then the R4 tires and will seem more stable.

11.2x24 R1 tires at 75% fill will weigh each tire:
water-200 lbs, 3.5lbs of CaCl/gal-237 lbs, 5 lb CaCl/gal-253 lbs

15.00-19.5 R4 tires at 75% fill will weigh each tire:
water-240 lbs, 3.5 lbs CaCl/gal-294 lbs, 5 lb CaCl/gal-320 lbs
