Looking a picking up a baler to get running over the winter.  I have several choices as to brand...but the one that caught my eye and would tickle my fancy would be the Oliver 60 twine baler I found.  

My 2 questions are:

How heavy a bale does the 60 make?  (Alfalfa to compare apples to apples.)

Do they have any known weaknesses or quirks?

Thanks!
