I've got a loader on my Ford 1600 that isn't very useful for all the logs and brush I need to move. I thought that it couldn't be very difficult at all to build a grapple that fits in place of the bucket. I was thinking a heavy "rake forks" bottom with maybe a three or four claw top with one hydraulic cylinder, maybe 48-52" wide total. Maybe 6-7 forks on the bottom 32 inches long or so mid braced and welded to a cross member at the rear. Get a 6-8" reach 2 or 3" hydraulic cylinder, a simple control valve and maybe a solenoid hydraulic flow switch or a bypass control valve and splice it into my loader hydraulics. The 1600 is fairly big for a compact tractor, but it isn't that big, so I have to keep weight reasonable so it still has plenty of lifting capacity. I've lifted well over 1000lb with it before, but probably shouldn't go over 1200-1500 regularly. The tractor only weighs about 2500-2600 without an attachment.
I was thinking about what steel tube to best use to keep construction simple and adequately strong. I think some 2x2" .180" square tube with adequate bracing at angles would be a good start, with maybe 1/2" bar stock for attachment flanges and such. I have all the fab equipment I need to manufacture it. I found a really nice design or two on the internet that I think I could imitate, but with a little more simplicity, and they actually used quite a bit of lighter gauge 1x2" rectangular tube.
