Sadler, you can't go wrong with the Long 4&1 bucket. Had both JD and Long HD 4&1 buckets on my JD and the Long is much better built with heavier gauge steel. On the downside it is also weighs more. But, the extra weight bucket is a plus when back dragging in float mode.
Check out the "spill plate option" Long puts at the top edge of bucket too. This keeps material from falling on hood when bucket is high and fully tilted back.
Also, on the Long tooth bar, if you push a lot of brush you might want to consider adding a couple of extra teeth to close up their spacing. Close bar teeth make for a better raking/combing of brush.
cheers,
