I have my eye on a 2011 Brandt 7500 grain vac. Those of you that have one, how do you like them? Pro's con's? Another concern I have is the power required. We have a Massey 6180 to run it, Tractor Data claims it has 110 PTO hp, which might have been in our tractor's hay day, but probably not there now. Brandt claims a minimum of 110 hp, will I have enough? We would never likely load out of a full bin, so assume that's where it would take the most power? Really need to update our old Rem 552, sooooo painfully slow! Sick of spending days doing what should only take a few hours.You know it's bad when you consider just shoveling instead of vaccing!
