DrDan, I would say with my experience with my BX that it handles the 4 foot 7548 Boxblade very well but a five footer I do not think is a good match for the BX. If you think you need a five foot Boxblade you probably need a bigger tractor. I use my BX to smooth, level my drive and also to put out something in the range of about 35 tons of gravel onto it--maybe it was 30 tons, forget already. Why do you need a five foot? It seems to me that the BX might be perfect for your situation, being lower, it would be easier for you to get in the saddle and back off and all around easier for you to deal with but then if you need something bigger you need something bigger--BX is a fun little machine though.
