LOL, somebodies gonna get in trouble if somebody else see's this post
With no FEL or BH mounted my
BX23 is less tippy then any other machine I've owned. This includes riding mowers.
That said, adding an FEL redistributes the center of gravity higher which makes it more top heavy hense more tippy. Adding a load to the FEL makes even more top heavy. Adding the BH to that and the center of gravity is very high.
Likes been said, when traveling with the FEL, keep it low no matter whether it's loaded or not as this will keep the center of gravity lower. When traveling with the BH, reduce your speed even more and be careful on rough uneven terrain.
The more the load, the higher the probability of tipping.
Just be careful and enjoy
