I have a 2007 BX2350. Motor is 54 ci. Dealer installed a 1200 watt block heater on it. I asked him about it being so big and he said they installed that size on all Kubota's. I would think it would have a meltdown with that big a heater. Will only plug in for hour or so as needed, not plug in all the time. What size are your heaters? hjt
