we run a team of the lighter narrower 200s here, both set up preatty much the same. one is a turbo 110 cummins and has live hydraulics, feedwheel lift (must have), handcrank swivel discharge, 64" infeed tray width(standard on 250), steel fuel tank (much better) cone holder (convenient) radiator screen (must have helps keep radiator clean), radiaotr guards (saved us a radiator more than 4 times). the other is a year older and doesn't have live hydraulics and only has 86 hp ford bsd 444 naturally aspirated diesel burning, burn your eyes, 45 year old design, american muscle. not only is it quieter, but it lugs better. never had an engine part go wrong with that one either, except a block warmer. if you get a feedwheel lift option YOU NEED extra aluminum hinges where the lever attaches to the valve, thisis the weakest part on all BB chippers. very cheap part, but annoying as hell to work without. also change blades as soon as they go dull, and keep anvil adjusted and shaped properly. this greatly extends the life and durability of your knives. to save time i change the blades with blades that are the same size or slightly larger so i don't have to adjust it everytime. also get a spare set of cutterwheel belts, they last a good year or 2, but once they go, you're screwed. you can chip small stuff with 2 belts though. all in all BB make a very good machine, our next one will prolly be a 254 or a 1590 if not bigger.
