B7500 useless in mud

( The new tractor will not do the work of my 2WD Yanmar 1700 in mud )

You have stated the configuration of the B7500 4wd.

What is the configuration of the Yanmar 2wd? What type tires? Loaded? FEL on either tractor?

I don't know anything about the Yanmar 1700 (hp? weight? etc), but I have a hard time believing that a 2wd tractor will out perform (have better traction than...) a 4wd tractor of similar weight and hp.

Tell us more about the Yanmar so we can better help you,

Glenn1,

I have a B2910 with R4's. I was helping out a neighbor back in the fall and the ground was very wet. I was intending to do some rear blade/loader work, but our clay is so slick that I had to give up on the effort. The tires would just spin once the mud formed. The tires were doing more damage to his lawn than any help I could've given with the loader or rear blade. /forums/images/graemlins/crazy.gif

Fortunately, with the ground wet, it's not as hard to dig by hand.

Our clay is interesting stuff...when it's wet it's slicker than ice on ice...when it's dry it's like concrete. Most of the time I need to dig in it it's like concrete...and that why I got the B2910. /forums/images/graemlins/grin.gif

If I had to do a lot of work in mud I would get the Ag's. If I ever need to work in mud with the R4's, I will but the chains on. However, they only help if the mud has a "bottom"...I don't think I want to find out how deep our "bottom" is. /forums/images/graemlins/crazy.gif

We should also mention the drawbacks of R1's or Ags. While this is not everyones experience, but the R1's on my International as well as a few other tractors I use also tear up the turf easier which may or may not be a issue for you. They typically do not have the ply or weight rating of the R4's which is a problem on the front tires on our L4850 which with a load of wet material will overload fully inflated R1's. On asphalt and concrete they wear much faster which shows up on the front tires on our NH 2120. On the other hand, it's tough to beat R1's traction. For all around use, R1's can be a great choice.

My tractor sits quite high enough, if throwing R1's lifted it up more, I would consider that a drawback.

Speaking of tires, aren't we still waiting for a tire report from Glenmac? He was using Michelin tires that were radials and had a much sharper and defined cleat then the standard R1's you get with the tractor.

Rat, the difference with the higher cleat angle will enhance the cleaning. Years ago some one did a study of the merits of the bar angles. The 23 degree bar gives 7% more traction then a 35 degree bar on solid footing. The 35 degree bar in mud was at least double the seven better in mud.

I would almost bet that my JD 4400 with R-1 tires would out perform your JD 4700 with R-4 tires in slippery/slimy/sticky red clay. The R-4 tires are not worthless but they will not give you the traction or clearance the R-1 tires will in the deep mud and hollows in extreme circumsatances where you need it most.

at some point in time, with differnt conditions, type of ground, type of mud, work being done etc. any tire in time will make u wish u had something else. onmy old tractor 2 wd, with ags and chains i had some problems under certainn conditions, like getting the front end down and she would struggle to free herself, now this tractor 4wd with r4's under the same conditions does much better. pont being NOTHING IS PERFECT. and a lot of the traction has to do with the wight of the machine

I've never seen anything that's really good in deep mud. I notice my farmer neighbors have those big rigs with 8 tires..

One question would be how your ground clearance is? Do you have anything beneath the tractor that hangs you up? Mid-mount mower, front blade with its' supporting underframe?

People I know try to have two tractors.. one for work, and one to pull the other one out when they get it stuck. /forums/images/graemlins/smile.gif

R-1's are best for mud and cow pastures snow,but an R-4 is easier on turf and the hard surfaces are harder on the R-1 tires for sure.

( I agree with Greg something is wrong with this story. By that I mean something is being missed. )

I am beginning to wonder if this ever was a story.

Glenn1 created an account on the board (and put no information in his profile) and then generated this one post. As of my post, Glenn1 had still only made one post.

Every so often there is someone that will make a post simply to "bash another competitor's tractor". I'm beginning to wonder about this one...

You should find out more about someonee before you make a statement like this. My profile has nothing to do with asking a simple question. /forums/images/graemlins/mad.gif
