The subframe on the Woods BH9000 must be designed a bit different from the subframe on the Kubota BH90, because after reading about three different people complaining about bending stabilizer arms, I just had to check. I removed the rear blade so I could wiggle the lower arms back and forth, and couldn't find a position where they would contact the subframe. Guess that's another good reason for choosing the Woods over the Kubota backhoe.
