Tailgate Lift Cylinders
Round balers open their rear gate to release the finished bale. Tailgate lift cylinders connect the main frame to the hinged gate, converting cylinder movement into the rotation needed for opening and closing.Their size depends on gate weight, mounting geometry, available hydraulic pressure, and required opening speed. Some designs incorporate end-of-stroke cushioning to reduce impact as the gate reaches the end of its movement.Where two cylinders operate one gate, the complete mechanical and hydraulic arrangement must support coordinated movement. Cylinder dimensions alone do not guarantee synchronization.
Pickup Lift Hydraulic Cylinders
The pickup collects crop from the windrow and feeds it into the machine. A pickup lift cylinder raises the assembly for turning, obstacle clearance, or transport, then returns it to its working position.
A single-acting cylinder can suit a pickup that lowers under its own weight. A double-acting arrangement may be used where powered movement is required in both directions.
The cylinder should work with the pickup’s flotation and height-control system. Gauge wheels, springs, stops, and linkages may determine its working position and ground-following behavior.
