Would there be a need to run 3 combinesIJ If you don't have much money tied up, an extra machine would be nice to have as a back up. Our main combine is a M2 but we have a F2 that kinda serves as a back-up. When my first M burned I sold it to a salvage yard for $2,000.00. Wished a thousand times that I had kept it. Good luck in your decision. T3 P.S. My torque sensing box on the traction drive turned out to be the clutch slipping. Adjusted it all the way out and made it through harvest. Will rebuild clutch and pressure plate this winter. Thanks for the info. T3
