Craftsman DYT4000 Riding mower overheating
I have a Craftsman Deck Yard Tractor 4000 20hp.I have had it for four years and I haven't had any problem with it until recently. I had it ideling with the lights on and when I attempted to go forward it shut down. I looked and found that a fuse had burned out. Now when I turn the lights on the fuse immediately burns out. Yesterday it caught on fire. It seems that the crank case in the front was dripping some oil. Not a lot but the tractor heated up and the crank case was on fire and there was oil on the muffler and that caught as well. I put it out it didn't seem to do much damage. I cleaned everything and tightened down the head of that crank case. I topped it off with oil and stared it again. This time I noticed just after about 20 seconds that the tube exhaust where it hooks into the muffler was red hot. Any idea what my problem is? Thanks!
