Abstract
A suspension system for a boom of an agricultural particulate material distribution system comprises an inclined strut extending from the boom upwardly and inwardly to a suspension element at the tank. The suspension element comprises a plate attached to the rear wall of the tank and projecting outwardly to the side of the tank on which is mounted a pivot lever having a lower end attached to the plate and an upper end carrying a swivel for attachment to the strut. A gas bag spring is located in a hole in the plate so as to accommodate shock loads applied to the lever from the boom. A self leveling switch increases and decreases pressure in the gas bag spring to maintain a required orientation of the boom and to move the boom to a raised position for avoiding obstacles and for folding.
