INTRODUCTION
OVERVIEW OF THE OPTIONAL STONE PROTECTION ASSEMBLY
The optional stone protection assembly is designed to prevent damage to the steering discs and disc legs. The
assembly consists of one bracket and cylinder for each leg and a hydraulic accumulator.
If a disc contacts a rock, the optional stone protection assembly allows the disc and leg to adjust depth
independently from the implement and ride over the rock. This helps prevent damage to the discs and disc legs.
