I found a used knight reel auggie TMR mixer for sale locally its a model 2170 reel mixer guy wants $1500 for it havnt gone and looked at it yet but wondering what I should look at when purchasing a used Mixer augers, floor of wagon, etc???  

I would use it to feed Holstein steers (300-400lbs to finish) rations would be a mixture of corn stalks (would they have to be tub ground if they were chopped fine in the field before baling?) Modified wet distillers and shell corn and a balancer would it make a good mix with ingreidents listed above?

Any thoughts, ideas or concerns are greatly appreciated!
