It has been a while since this post was active, but, since Perdue University has called me a liar, I want to respond with the fact - BIG MO is 9' in diameter - and that is head size NOT size from lugs to opposite lug - that would make it about 9'5" and NOT distance from the bottom wheel of the cart to the top (that would be over 11', but the actual head diameter -9'. The Purdue (is that where the chickens come from?) University drum is 7'3" in diameter. that is the published size AND the size of the head they order from REMO. I really do not care who has the biggest drum, but I hate being called a liar.
