I had grand backhoe ideas. Purchased A BH92 with a hydraulic thumb.
Having used it a lot, I find it lacking and slow. Trenching is best done with a helper. You dig, then have the helper move the machine forward.
I find it will dig stumps out...but takes a long time.
Mine is on an
L5740. I continue to be surprised by the low level of power of my BH92.
Looking back, I wish I had not purchased it. That $11,832.00 would have been many days of rental of a mini-ex. Even better, you can probably find a good man with a track hoe that will work for $800/day.
I know that is not what you asked but I thought I'd offer my experience.
Edited to add: As long as I've had the stabilizer arms and bucket down, I've never had the BH92 even threaten to tip the tractor. I've dug most angles with mine.
