Abstract
A suspension arrangement mounted in support of a boom lift assembly and boom supported thereon on a chassis of an agricultural sprayer is provided. The boom lift assembly is configured to move the boom between a raised, inoperative position and a lowered, operative position. The suspension arrangement includes a pivot linkage pivotally coupling the boom lift assembly and the chassis, and a dampener located between the boom lift assembly and the chassis. During operation of the sprayer, the dampener of the suspension arrangement reduces transfer of an impact force or stress force from transferring between the chassis and the boom lift assembly so as to isolate suspension of the boom lift assembly from the chassis of the sprayer.
