- Challenger MT655E, Massey Ferguson 7495, Challenger MT535B, Krone 4x4 XC baler, Kubota F3680 & ZD331 Ram 5500 Cummins 4x4, IH 7500 4x4 dump truck, Kaufman 35’ tandem 19 ton trailer, John Deere CX-15
Massey 7495 tractor with traditional dash cluster tach. After running for a couple hours and presenting correct tach speed (compared to digital readout), the tach goes past the correct reading (2000RPM) creeps up towards 2500RPM, then into the white zone and sits just there.
Turn tractor off and it corrects itself, reads properly and 1-2 hours later, it does the same thing.
Any thoughts on cause or repair?
