Looking for someone to tell me I am on the right track.
I am switching my NH3930 4wd from 9.5-24s and 14.9-28s to R-4s. I need to keep the ratio the same for the 4wd.
Using Titan/GY specs:
For my current tires I came up with 78.8% front/rear.
Switching to 12.5/80-18s and 16.9-24s, 75.1%. (rear tires going faster)
12.5/80-18s and 17.5L-24s, 79.9% (front tires going faster)
Do you agree I need to go with the 12.5/80-18 & 17.5L-24 combo? It will be off by only 1%. Plus air pressure in the tires will vary that a little.
I can put the 12.5s and 16.9s on, as I already have them all, but thinking I should switch out the 16.9s for 17.5s.
FWIW, the R-4 option on this tractor was 11.2R20/16.9-24. The 20" rims are impossible to find. The tires I have worn out and need replaced, and I need to switch to the R-4s.

An improperly torqued capscrew on an engine head or a shear bolt that is too hard on the driving shaft of a bushog can create havoc and make an expensive and uncalled for repair. Let�s examine the purpose and design of these fasteners in order to ensure their proper use. Fasteners are probably one of the aspects of mechanics that is given the least amount of thought.
