I recently mounted two sets of clamps to my tractor to hold securely my farm jack and a prybar. They can be used to hold shovels, rakes, whatever... as well. Very handy. They are sliding clamps with a HD buttress thread for tightening where you can generate a tremendous amount of clamping pressure.
Mine ride on 1/2" and 3/4" pipe nipples that are threaded into NPT base. The length of the nipples can be changed to hold various configurations. I mounted the bases to the ROPS via 1/4-20 and 5/16-18 bolts. I know it's not suggested to drill into the ROPS even though the major part of it is 1/4" thick, but I found out that at the bottom where the ROPS is welded, it is solid steel. Much to my surprise because hand drilling 1" deep into steel with a Makita is very hard.
I positioned the clamps so they were out of the way during different operations, including working the backhoe, locating them neatly behind/rear of the ROPS. I tested them out while doing some road grading and found they were stable and did not work themselves loose during this try-out. I imagine, hovever, like andy of the bolts on the tractor, it will be wise to check them for tightness before each use of the tractor, or at the end of the day to make sure they are still tight.
Picture attached of them empty.
