The block heater on my BX stopped working after only using it twice. The tractor has just turned over 50 hours total time since new in July of this year. AI don't see where it gets any power from the tractor so I assume there is not a fuse connected to the heater. It has to go in for its 50 hr service in the next couple of weeks but wanted to see if anyone else has had this issue and what they have done to remedy it. Thanks
