Anyone using these in just wheat? Dad saw an ad for these and is excited. They say folks are getting 3500 sep hrs of wear out of them and way less losses. I tend to be a skeptic. We farm in the foothills of the Simco mountains and our soils are all volcanic. We've been test operators of several things due to the fact that we can wear them out faster than anyone. So what are folks seeing. Normally I buy the cheap small wire ones, run them two years, and throw them away.
