I have had my Yanmar on 2 wheels before.

Usually with a heavy implement the back and engaging in a high gear. But there have been times where I had to much weight on the 3 point and lifted the front of my tractor off the ground. Most recently I was trying to pick up my large pallet that I stack fire wood rounds on and figured I'd see if I could move it with the tractor. So i got the forks (3 point) on and backed into the pallet, lifted and put into 1st gear. At the first movement my front tires were 1 foot off the ground. So that was that and I lowered my 3 point. When i got my tiller i backed the forks under it since the hitch was not at the time imatch adaptable and I had to use my steering brakes to get it out. That was even with 200 pounds of extra weight on the front too. I got it home but i don't really like being on the back 2 wheels for safety reasons and lack of steering, even with steering brakes. Last spring i was clearing a spot to extend our garden and caught on a stump so i lifted my 3 point and up goes the front of my tractor. Scared me at first but I got some pictures really quick for laughs. :laughing: I have had times where i was on the front 2 tires with the 3720 moving pallets of stone and didn't like that either. Thus I put my rear blade on the back for ballast and loaded it up with 8 of the 40 pound weights for ballast. I don't necessary recommend going on 2 wheels but some times it may be something that just happens. In my approach to equipment, it is always safety first. If it doesn't look safe, I'm either going to find an alternative or do it when conditions allow the tractor in the area safely.
