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.
