How do I know a tractor's limits?

[newbury]

The only way to know the true limits is to bypass them but you should know when your getting close.

Shear pins shearing, engine bogging down, tires lifting off the ground, bending things, etc. are all warning signs but the #1 way of knowing your at the limit should be that little voice inside your head saying, don't do it!

Or when other parts of your body warn of danger.
The one "danger" area is determining the maximum slope you can traverse before the tractor lifts a tire and tips over.
Happened to me the first time I used my B7610 offsite.
Had a bucket full of sand carrying from truck to destination. Maneuvering around on a side slope the right front wheel dropped into a slight covered hole. Left rear lifted up. First indication of danger was my sphincter muscles immediately (about 1 nanosecond) clamping down as the angle of the seat startd to change. I dropped the bucket and hiked out to the left.

Rolling or flipping a tractor is generally considered a bad thing.
