Hi, I have a question about the backhoe stablizer arms. I have a 1580 backhoe on a 1547 Massey. I was wondering about the stablizer arm design it doesn't seem to be all the that heavy. Has anyone had a problem with the assembly. I plan to do a major probject and I will be working in some rocky soil. I just don't want to put too much torque on the arms with the claws down. So was wondering If anyone had used their hoe in rocky soil and how the arms held up? Thanks for any information.
