Hey jdmidwest, I agree with crusty, get a set of Michelin 800 duals and 750 rears, you will hardly make a mark. Michelin also makes a 650 that goes right on your rims you have now, they are XM-108's. If you have enough tire, and run the pressure down where Michelin remommends, you will float.
Hey crusty, how many acres do you have on your harvestec?
The next step for us would be the 12 row, but my main concern is the axle load of a combine full of corn with a 12 row head. That is ALOT of weight. Right now we can make the back of a corn field in 225 bu corn with a 8 row and 2100 foot rows with the standard bin. Going to a 12 row really changes the dynamics of harvest corn for us. The buggy would have to hold a full round, and in our best fields it won't if we are cutting 30'.
The next issue would be the unload auger on the buggy would have to be fast enough to unload a full bin and get back under the combine BEFORE he gets to the back of the field. I know this can be done, but things have to tick along pretty good with 1 buggy supporting a 12 row machine in high yielding corn.
Crusty, do you run 1 buggy or 2?
