Yes! Exactly same problem, with the same tractor, happening intermittently over a 3 year period, and last week found out why. Took the instrument panel out and disassembled, and found that the stop pins where the gauge needles rest when powered off, were covered with a tarry material that 'glued' the needle to the pin. Tried to clean the tar off, but difficult, so put a very small shrink sleeve (electronic wire type) over the pin, and all's well!! Evidently the gauges would work once the 'tar' got warm enough and/or vibration got big enough to release the needle(s).
I have the same problem with my 2009 Mahindra 4025 with the fuel gauge and temp gauge stuck on zero and the tach acting erratically. Not wanting to pay the price for a new Instrument Cluster I am tempted to try your fix. Were disassembly and re-assembly very difficult? Would appreciate any tips or suggestions on doing this.Yes!
