Here's some reminders from the Penn State article:
"Four-wheel drive tractors are less susceptible to the rear axle torque hazard than two-wheel drive tractors because torque is applied to both the front and rear axles and tires. Also, more weight is carried on the front axle, moving the CG forward". [another advantage to 4WD]
"By design, a load will always lose its ability to tip a tractor rearward before the tractors CG reaches the rear stability baseline [using the factory drawbar] . As the load loses its ability to continue to tip the tractor rearward, the front end falls back to the ground. If the tractor operator doesn稚 stop the pulling action, the entire process will repeat itself, resulting in a bouncing of the tractor front end".
On the other hand, hitching unsafely, for example to
a point higher than the drawbar, increases the angle of pull and leverage of a load."
The roll-over protective structure (ROPS) and seat
belt, when worn, are the two most important safety devices to protect operators from death during tractor overturns. It is important to remember that the ROPS does not prevent tractor overturns." :thumbsup:
