As i posted earlier under wrong heading.. PROBLEM?? can't use the rear 3 point hydrolics, box blade, without the 60'' mower also going up and down, the same time the rear blade does? Help?? Michael
Try setting your "mower height control knob" to the "top" position. This will prevent the mower from dropping completely when you lower your three point hitch. Good Luck
Does your mower have several arms that can be used to hold it in the fully up position regardless of what you are doing with the three point controls. My B7100 mower has these.

Tractorman is right in his answer. You may have to hold the lift lever back with your hand to get the mower high enough to "pin" easily with the knob under your seat. The knob can be hard to turn otherwise. Hope this helps you with your problem.
