Quick-attach plate with pallet forks for FEL. I cannot begin to express how useful the pallet forks are for my needs. It seems I use them more than the bucket, although I am constantly switching. I move stuff, loosen up roots around stumps, put all my implements on pallets, built firewood racks out of pallets (only touch it once!), built a man-lift platform, move logs, etc.
Oh, and I second the need for a bucket toothbar. However, make sure you get one that is easy to get out of the way. Mine has slots on each side where it is bolted to the bucket. That way, I can loosen the nuts, pull it forward, and then flip it back into the bucket if I need a smoother cut. I have no idea what brand it is....
Finally, I like my TSC logsplitter. It is slower than I like for the cycle time, but it is comfortable to use and hasn't been stopped by any log.
