I use a BX for orchard work and it would be simply impossible to use it with the ROPS. In fact snagging the ROPS on a sturdy overhead object can cause the tractor to tip. When using the FEL I make sure to have an implement on the back for counterweight and use all due caution. I do have hilly ground so must be real careful even without the FEL when mowing side hills. I have actually tested the tipping point of my BX1500 with MMM by stopping crosswise on my steepest hill, getting off, and gently lifting the uphill side to see how near the tipping point I was. Answer was it was not close to tipping at all. But of course you need to allow a real big safety factor because running over a squirrel hole or hidden piece of firewood will drastically change the tilt.
