In reading this thread Henro mentioned the limited lift of the BX 3ph, something I know nothing about but. . .
The BX is a pretty small tractor and does not have a lot of lift on the 3PH. For example, on my BX2200 I could not lift my 6' landscape rake enough to swing it around. End hit the ground.
I was able to drill new holes higher in the lift rod forked ends, to increase the 3PH lift enough to swing the rake. Simple enough to do.
Still, I doubt I could use my PHD on the BX. Have never tried it, as the B2910 is more suited for it, especially with T and T, so I can slant the PHD if sitting on a slope, at a cross angle.
I believe I read in the past that PHDs for use on BXs are available, that have shorter vertical height. Never paid much attention, as no need at my end.
