Grappling fun - A Picture Thread....

[IslandTractor]

Ya, I think many would be surprised how much of a difference it makes as you move away from the effective point of pivot. I also think the distance and reduction in lift capacity are not linear. In other words, the farther out your load the bigger difference it makes. So a few inches at the end of your loader can make a huge difference in lift capacity.

No question that the farther the load is from the pivot point the greater the force needed to lift. However it is, I believe, a simple arithmetic function. Twice the distance from the pivot point requires twice the power to lift. There is an additional factor which comes to play with a loader though. The geometry of the loader and cylinder changes as the load is lifted and generally loaders are optimized to get stuff off the ground rather than lift to full height so the trigonometry means that the cylinder cannot provide the same lifting power all the way from ground to top.

As promised...first grapple picture. I had to make a few trips back and forth to the place that made my hydraulic lines to get the right fittings so I was running out of daylight by the time I got to try it out.

Antlers through the tines. Ingenious! I thought at first you had speared it!

Nice, well worth all those parts trips!

How did you catch that deer with your grapple?

Kubotas are just that awesome!

Yes, thanks! Makes sense that it is a linear relationship now.
I asked the original question about the rock weight because I would have guessed a little lighter and wondered if I needed to "recalibrate" my guestimator.

Got to try out my new grapple on Sunday...thanks to everyone who who suggested I get this Attachment.
