We have a quick attaching bucket, pallet fork, and hay spears for our 7810 John Deere. Our loader is also a quick attach and deattach. The total time to remove the loader is less than 5 minutes.
I second the comments on the grapple. So handy when moving brush.
Mine has the quick attach bucket setup so swapping out front end implements should be pretty simple. I don't have any other attachments at this point, but have considered pallet forks for things like this brush pile I just did as even those would be a huge improvement over just the bucket alone. The grapple would be a nice addition, but as I mentioned in reply to Scott's post, I don't know if the tractor is set up for one or not.
Forks are pretty good for moving things like logs, picking up downed trees to easily cut up with a chain saw, getting your chainsaw out of a pinch situation, and I can go on... Great attachment, and I would buy one. Very many uses, and your back, arm's, leg's, head, family, friends will thank you, But...
...They really suck at moving brush! Got a steel grill on that baby? Brush has a way finding the right passage thru the grill guard, and you don't have one, to mess up the grill. I need a new one on the Kubota, and they ain't cheap!
