It takes a big air cylinder for the big baler.  The air cylinder housing must be balanced in order for ease of handling.
The Calverts used extra springs (small silver springs) to balance the cylinder, but feel that if the A-frame was more
center that this might not be needed.   Guide rods on either side help insure a level press.  The press runs on a barn
door track.  Some have suggested a cheaper hydraulic cylinder, but hydraulic cylinder could damage tobacco if a leak
occurred.  This cylinder is made in Lexington and costs approximately $1200.
