Combines duals or RWA

[CAJUN__BOY]

RWA would be my pick depending on what tires you have on the front now RWA lets the pull more evenly your not draging the rear axile CIH and all the new machines with engine in rear the rear axile has a lot of drag down hear every year is a wet one, we use 900-32 R2 on front 23.1 26 R2 on rear these big boys seem to stay on top better

No brainer, the back is what normaly gets you stuck as those wheels start to slide and drag the whole machine down, Pick the RWA. We use 28lx26 on the back and really like them. Have one machine with 18.4x26 on back and it wont come close to going where the 28lx26 will go.Duals on front are normally too close together and mud balls up between them, then in cleats and you loose the advantage of the added flotation.

have a neighbor with 2 JD cts one with duels tried to order second with duels had some trouble they put the 35.5-32 on it til they could get the duels for him, now he dosen't want the duels says these big singles will go where the duels won'tIJIJIJIJIJ

It depends on how much MONEY you want to spend. We have 2 combines, 1 with RWA and 1 w_o. We had a hub made to run an axle mount dual with our 30.5 x 32, there is 12 inches between the two tires. Never any mud buildup just problems with narrow bridges. With the duals, it was like running singles with the RWA. Now both combines have duals! I think the hubs were around $750 for the set. (I thinkIJ) And they are very easy to get on and off.

I'd go with both if you could squeeze it into your budget somehow. I find the duals increase your traction a bit...mostly help with reducing compaction and stability. The 4WD is the biggest benefit if there's a need to harvest in wet conditions, especially if you're in uneven ground. If you can only choose one...go with the 4WD, if nothing else it makes roading the machine easier than duals.

I believe that alot. I think a wide flotaion style of tire will get you just as far as duals. A person gets mud between the tires and your asking for trouble. Thanks for the advice.

When you say "heavy soil", do you mean soil that stick to tiresIJ We have some clay that will quickly pack between duals, so we went with large singles. Assuming you have 30.5-32's, the most economical way I could find to improve the machine in mud is to go with a set of Trelleborg 900_60-32's. They will fit on the same rims but give a much larger footprint. The lugs are very tall and the rubber is hard. Mud does not stick to it as bad. When you really need to, you can lower the air pressure down to 12.5 psi and still carry most of a bin (I wouldn't probably go over about 150 bu at that pressure) assuming you have a grain head. With a corn head, you will probably need more air and you will want to pump them back up to around 16 psi as soon as you get to dryer ground. I think you will find that to give you the most bang for your buck, and probably get you by. If you want to spend more, the large Michelin 1050's are awesome, 4WD with oversize rear tires help a little, and tracks are the final solution. Unfortunately, the cost goes through the roof to get that last bit of mud performance.
