With 425 hrs and a recently expired warranty I have been having some reliability issues that are now not covered. First the battery was draining for some reason. Charged it back up and ran the tractor---no problems.
While running it I found the headlights coming on when the switch was off. Cycling the headlight switch on and off several time finally resulted in the lights turning off. Put the tractor away and come back two days later to find the battery drained again.
Had the battery tested at dealer and he said it was still real strong. After going through this scene several times the dealer sold me a switch for $38. I installed it, ran the tractor and found the battery dead again. I disconnected the relays (disabling the headlights). Problem has not come back. However it hasn't been resolved either just mitigated.
The next problem to come up was a fuel leak at the fuel filter. Found several cracks in the bottom of the fuel bowl (plastic). There is a spring in the bowl beneath the filter which keeps pressure on the filter to keep it seated properly. The combination of pressure, vibration and solvent properties of the fuel have weakened the plastic so it is now crazed (lots of little cracks) and leaking. It should be recalled since it create a fire hazard. Poor design; should be Pyrex glass bowl instead of plastic.
