Combines 2388 w

From my three years of use I find that in no-till situations they tend to stay on top of the ground with little rutting during a wet fall But, in conventional tillage and a wet fall they just make a wider rut. With that being said I prefer them over duals. It appears at times the flotation tires "slick" over but they have never failed to pull the combine through some of the heavy clay ground I farm.

We like the floater tires a lot. Not many duals around here. The reduced compaction and rutting is a big plus for no till, and if you ever have wet harvest conditions they will pay for themselves quickly. It takes a lot of fuel to fix a field full of ruts, and with these tires you can almost eliminate ruts in all but the worst conditions.

I have tried, but for the life of me understand your logic about air pressure and its relationship to ground pressure. The amount of weight applied to the ground is measured in PSI as you noted. Therefore, it is a function of the "Pounds" (the weight of the machine) divided by the "Square Inches" (the contact patch of the tire). larger tire equals larger contact patch, equals more square inches, equals less pounds per square inch.

Farm Kid2, Did you ever post the pictures of your 1688 with the monsters to Farm PhotoIJ I believe that it would help there people understand immensly what you are saying. I know it did for me. Chuck

So if you ran them flat would you not leave a track at allIJ

Deadduck. If you could pull a vacuum on your tires, could you make it hoverIJ

Ok I knew i'd get a bunch of smart as remarks posting this, I'll try to explain it to you a little simpler. Get your wife to put on a set of high heals and have her stand on your hand with the heel, hurts like hell doesn't it, now have her step on your hand with the front part, wich one would float better in the field. @ the toe part you may be exerting 100n but at the heel your probably exerting closer to a ton. Here's another, step into your wet field with your boots, now stand on a large beach ball, whats going to leave a bigger markIJ You have to look @ your tires as an air chamber wich in effect the air inside acts like a suspention between whats on top and whats @ the bottom. Trust me I spent a week @ goodyear's prooving grounds in texas arguing with there farm enginers how is that possible. Seen it with my own eyes with pressure bulbs burried in the ground. Minimal air pressure is key to leaving ruts and reducing soil compaction, I've been doing it for over 5 years and its worth every penny especially in wet springs and falkls, Try www.goodyearag.com , firestoneag.com, and michelinag.com They all have there own load inflation tables and they also teach about ground pressure.

Is it possible to run a 6 row head with floater tires on a 1688_2388

If you can with factory duals you can with the 68"X 50"X 32" that I run because the overall width is about 8" to 10" less.
