That is why the Rapid XZ has a ROPS.
That is true. We've had row crop tractors on the farm for over 70 years. With a sickle bar mower on the back, the most likely side it will rollover on is the left side. It won't rollover backwards as as soon as the front wheels lift a foot off the ground, the mower frame is on the ground in the rear. Same with the plows.Comparing your 4WD with blocks on the axles is far different from most farm tractors especially ones of the same era Narrow Fronts were built but even 4WD drive tractors can be turned over as most turnovers are the result of driver error or miscalculation.I've seen wide track bulldozers flipped over.One of the most common ways tractors are flipped is when heading downhill with a load like a silage wagon thats loaded the wagon will push the rear of the tracotor around and flipped the side ways tractor.Also over the years I've observed that most 'experts' on narrow front tractors are folks that have never actually run one.
