Jibber:
I have had two tractors, one with a standard loader bucket and one with a 4n1 bucket. If I were buying a new tractor, I would definitely get the 4n1 bucket. The FEL is the most useful implement you will have, and the 4n1 bucket just increases the flexibility. It allows you to use just the back of the bucket as a dozer, srape with the front, and grip things with the clamshell effect. I have used mine to move railroad ties, logs, lift stumps, grip rocks that wouldn't scoop easily, and I am still finding new uses for it. The only thing it doesn't do well is haul liquids (like watering flower beds), 'cause it leaks out of the bottom. You could add a removable tooth bar for better digging capability (haven't done that yet). You also could get a quick attach, similar to the skid steer quick attach system that would allow you to switch buckets quickly or switch to pallet forks or a grapple if you are moving a lot of brush.
Once again, if I were buying new, I would get the 4n1 bucket with a skid steer type quick attach system, as part of the initial purchase, rather than adding them on later.
Good luck with your choice(s). Welcome to TBN and keep us informed (with pictures, if possible). /forums/images/graemlins/laugh.gif
