B7100HST Weight?

[GlueGuy]

Cornfed,

As promised, here's the information from my friend (quoted exactly /w3tcompact/icons/smile.gif:

<font color=blue>9.5-16 long bar-short bar rears and 23" 8.50-12 skid-steer (bobcat)on the front seem to be the closest correct ratio.

I can drive in 4x4 on pavement with no binding of the power train now. With the original tires, the fronts had to skid 15" for each revolution of the rears.

If I remember, the ratio of O.D.'s is 1.4:1. I like the wide fronts 'cause they float better on soft or muddy soil than the 6-12's which are not exactly in sync with the big rears.

Bought at Gemplers an old farm supply catalogue co.

Let me know if that's "close enough" /w3tcompact/icons/smile.gif

GlueGuy,

Thanks for checking that out. I think that those sizes are different than mine and I will consider that when purchasing my new fronts. Thanks again, Andy

Andy,

Be sure to check what your front/rear turn ratio is before you switch! You might have a different situation./w3tcompact/icons/smile.gif

I have a 1995 B7100 HST and went back through the documentation that came with the tractor via the previous owner. He kept the original sales brochure and owners guide. You may want to do some checking because according to the "stuff" I looked through only Ag (R1s) and Turf (R3s) tires were available on the B7100 in 1995. And, I believe R4s have really only gotten popular the past few years (4-5) on compact tractors. To switch to R4s might require a different set of wheels. Just suggesting you check before investing hard earned $,$$$.

Bob,
My fronts are 6-12 and the rears are 8.3-16, both sets Goodyear. At the risk of sounding pretty wet behind the ears, I guess I really don't know about the R-rating that I'm hearing about. I think that they are four ply and I know that they are tubeless. I know that they are field type tires and they really like to muck it up in the mud, or is that me? Andy

You have regular agricultural type tires on your B7100. These tires have the most aggressive type lugged tread used on compact tractors, provide the best overall traction, and are designated R1 type tires.

Turf type tires are generally wider and on slightly larger (wider) rims, with a very mild tread pattern that won't tear up the yard. These tires usually provide the lowest degree of overall traction, and are designated R3 type tires. My B7100HST has turf tires with a front tire size of 20.5 x 8.00-10 and a rear tire size of 29 x 12.50-15. Same model as your machine, just different tire/wheel sizes.

Industrial tires, or the R4 type tires you've probably heard about, are kind of a cross between the R1 and R3. They have lugs like the R1, but are much less aggressive than the agricultural type tire, are a bit wider with a flatter footprint, and will provide better overall traction than turf tires, but less than ag types. These are pretty common tires on a lot of tractor/loader/backhoe machines.

Anyway, since you have the agricultural type tires, if/when you replace tires you'll probably want to stay with the same type tire. Otherwise, I think you might have to change rims, and that could get pretty pricey.

If you're new to compact tractor ownership, you might want to consider investing in Muhammed's book that's available here on Tractorbynet. Word has it this handy little reference guide provides a lot of educational material on compacts and it just might help you do a good job of taking care of that new B7100 and of even greater importance, operating it safely.
