I’ve had a third function (diverter) and grapple for 7 years (hard to believe it’s been that long). Have used it to move brush, rocks, logs, trash, smash small structures and stuff in a dumpster, clear greenbriar, and clear kudzu. I have used it to pick up 30’ creosote phone poles from the end like a baton to set them across a creek to make a foot bridge. Used it to gently set a two bottom plow in the bed of our elder predator neighbor’s pickup as part of extricating him from my father’s property when he “couldn’t figure out” how to get it in his truck. Probably some other stuff I’ve forgotten.
Can’t imagine any of the mechanical grapples I’ve seen being even close to as diversely useful as a hydraulic grapple with lid(s) that can be opened and closed at any point in curl. With the mechanical grapple costing the same as a hydraulic grapple and only cost saving being the third function, I wouldn’t even consider a mechanical grapple.
I’m aware the OP posited the cost of the third function would bust his budget, but a member that has routinely demonstrated mad knowledge of small/medium tractor hydraulics, and has helped numerous folks here through cost effectively adding third functions and rear remotes, offers to walk you through an option that gets you the superior functionality of a hydraulic grapple without busting your budget and your response is to argue it’s unrealistic to think American tractor owners have the intelligence or ambition to work on their own tractors??? Apparently an impression you got when looking in a mirror.
Get a mechanical grapple and deal with the limited functionality. If you’ve never used a hydraulic grapple, maybe you won’t know what you’re missing and you’ll be happy with it. Or buy the TYM and join a TYM forum.
