Rob-D Please excuse my ignorance with backhoe operation. I am more than interested as I await my new 2520 and my installation of a used #46 backhoe.
I have been following this tread with hightened interest after reading about members bending rams. Hopefully I will not bend the ram as I "slowly" get used to operating the backhoe.
I assume the section I must be aware of is highlighted with arrows. Looking at that section is it that as the bucket curls the position of the ram is also moving in an almost horizontal direction toward the boom? So it traps what ever is between the two and bends the ram over it?
That's correct but keep in mind that an obstruction can be under the cylinder also. The weakest point is midway between the mounts and the most vulnerability is with the bucket curled at max (the arm extended fully). As the bucket curls the piston to arm distance changes and an obstruction between the two has tremendous bending force.
I ran the 46 BH for years with no problems, even with the bucket snagged on rocks driving the tractor forward. It's a very good little BH. Make sure to keep it lubed especially the lowest joint on the bottom arm where it pivots.
