I have a 790 tractor that I would like to put a block heater on. I like the frost plug style heaters and saw the left side of the tractor has an easy-to-get to plug that I had planned to use (measures 1.175".....so it must be a metric size plug) and its at the back of the engine block. I didnt find any mention of the heater in the JD operator manual.
HOWEVER...when I went to the NAPA store to get the heater....the guy behind the counter comes up with a thread-in plug. I have an older (02?) 790. Do they have a threaded spot in the block for a heating element?? I would prefer that....but have been unable to locate that.
Anyone put a heater on the 790? What did you use? Also, is there a way to check the serial number for the production year? I think this may be an issue with parts as time goes on......so I better find out for sure. As my 790 has a model 70 loader.....It may be a bit older model than I thought when I bought it.
