14S—Lancaster Farming, Saturday, August 4,1979 For optimum performance and efficiency, the tires should slip just a bit, say University of Missouri researchers. Traction efficiency scored COLUMBIA, Mo. - Tractor tire slippage should run between 9 and 15 per cent. “Zero slippage would be very inefficient,” claims Ed Constien, University of Missouri-Columbia engine er. “That’s because you’d need so much weight to keep from slipping, you’d waste fuel hauling the extra weight around. “Any more than 15 per cent slippage and you’re waking fuel and causing excessive tire wear.” There are some fairly precise ways of figuring slippage, but Constien figures the easiest is to look at tire prints. “If the tire track where the lugs hit is tom up com pletely, you’re slipping too much,” he says. “If there is no break at all, you can afford to take sonje weight off the drive wheels. “The track should be broken out a little bit if slippage is in the optimum range.” He said experienced farmers can quickly spot tractor inefficiencies. “If they can see the wheels slip,” he says, “they know they have a problem and need to put more weight on those drive wheels.” Constien said farmers should have about 110 pounds on each driving wheel per PTO of horse power. “A fanner should be able to put in a crop of com for sue or seven gallons of diesel fuel an acre, unless he has unusual sod conditions,” says Constien. “This should be the amount of fuel needed for the entire operation: plowing, discing, harrowing, planting, spraying her bicides or using a rotary hoe, harvesting and shredding stalks. “If you’re using more fuel than that, there is something wrong with your tractor efficiency, you are tilling more than necessary or you have unusual soil conditions like gumbo clay. If you have gumbo, who knows how much fuel it takes to get through that stuff! ” Outstanding ag student named PITMAN - Don Snyder, son of Mr. and Mrs. Carl Snyder of Pitman, Pa., Was recently named winner of the 1978 DeKalb Agricultural Accomplishment Award.
