Tractor would not start. Burkhart's were kind enough to work on a blue tractor, luckily it was the same as a MX255 Magnum (except for the super steer and luckily, the hood clearance was higher than a Magnum). New fuel injection pump was installed but tractor ran rough. A faulty diode on the fuel pump wiring harness fried the new re-maned pump. Burkhart came back weeks later and re-installed a new re-man, wiring harness, injectors, o-rings, fuel filters, intake manifold gasket and computer. Later, fuel line #3 leaked and was replaced by Jess.
