The Adams’ new “HLS PTO/HYD” Lime Fertilizer PTO-driven hydraulic spreader is another addition to help enhance the Adams spreader line. This is our standard lime/fertilizer spreader with a PTO-driven hydraulic pump and 40 gal. reservoir added to the front. The PTO-driven hydraulics give the fans a constant RPM speed even at slow speeds or stopped. The HLS PTO comes standard in 304 stainless steel and has the same quality and workmanship that you fnd on any Adams. Adams has 40 years of experience in the fertilizer spreader market.
