I just bought my first tractor and I thought I got a good deal at 5500 for one with 777 hours (thought it was symbolic) that came with a loader, box blade, shredder and a tiller all in good to super good shape. Had to drive it to where I was going to store it (6 miles from the auction I got it) and on the way there it crept up to a little past the midway mark on the temp gauge. Pulled over and let it sit, then started it back up (didn't start near as easy as it did before) and got it the rest of the way there. Noticed that it had a little antifreeze on the inside of the cowling when I popped the hood there, and checked the radiator to find it slightly empty. Started it back up (very iffy that time) and pulled it over to where it was going to sit until I got back out to the country. I will admit, I didn't check the oil but there was only a little black smoke in on startup out of the exaust and wisps when I throttled it, but it was very hard starting this time (waited for glow plug light to go off before I started but it took 3 times of this and a lot of throttle to get it going). Do you think it may be a head gasket, or do you think I probably just damaged a glow plug or two. Also, how do you check the plugs. I also wasn't aware that it was a twelve speed, as there was only three settings on the gearshift and a reverse that I could read, all the other stickers (I guess that's what was there) are gone. How do you shift into the other gears? Any help would be greatly appreciated, I am starting to question my purchase even though there are supposedly 3 places in N.E. Texas that can get parts for this tractor.
