Depends like others have said. Studies show that in tilled ground duals can burn more fuel. Now, what was compared was a mfwd tractor with and without duals... same tractor just dropped the duals. This is assuming the tractor is large enough and weighted correctly yada yada yada. Without duals there is basically only 1 set of tire tracks. The fronts compact most of the track for the rears and that is what takes the most power/fuel. Drive your truck across a freshly worked field then drive back in the same tracks and you will easily be able to tell the difference. Anyways, with the rears running in the compacted area you only have to compact one set but with duals you have to compact the first set and an additional set. So, it depends and I don't remember how much it saved running without the duals but in theory that is how it went!

With Ben, anyway, I can tell! He'll be busy working and I�m handing him tools and he says, "give me that..." and I�ve already got it in his hand or "hand me that....."and I�ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th ... [Read Article]
