Thanks for the video..
....and the left front tire looks low.offcamber said:Nice video but I noticed everytime the tractor flipped they were turning the wheels up hill. Thats definatly going to cause an unstable condition. I suspect the tractor would have traversed the slope had they not turned the wheels up hill. Don't get me wrong I am not bashing the video just making an observation.
All non articulated tractors are built such that they stand as a tripod since that is the only stance that is stable regardless of surface shape. Four wheel tractors must center pivot the front axle to allow this. With a given CG and wheelbase each are comparable at the point that you get rear wheel lift. With a roll started purely by sideslope it is possible the 4wheeler front would stop it - but not likely. With a roll started by one rear falling into a hole the 4w would offer a true benefit due to the limit of center pivot travel on the fronts [not affected by the hole].wkpoor said:I would like to know if tricycle tractors are really more prone to rollover or if it depends on the situation. Seems many of the older narrow front end ones where wider stance in the back as compared to their height. I know some people are really afraid of narrow FE tractors but some old farmers say its hogwash about the greater rollover potential.

Thats just it, nothing is ever the same. Take a Farmall BN for instance. I would think those are more stable than my 5400. Lower center of gravity and real wide in the back. In the video I'll bet a 3 wheeler on the same hill would not have rolled. That small knoll gave a lift to the wide front end where the narrow would have just rolled over it.Of course a three wheeler is more unstable than a four wheeler if everything else is the same.
