Simple Sequencing Ops
The Unistack system is designed for simplicity and reliability. Its sequencing operation requires no electronics—just a straightforward mechanical process that delivers consistent, dependable performance every time. By eliminating complex components, the Unistack minimises potential downtime and ensures ease of use in any environment. This makes it an ideal solution for operators who value durability and efficiency without the need for technical adjustments or electronic troubleshooting
Low-Maintenance
Built for convenience, the Unistack’s low-maintenance design keeps your operation running smoothly with minimal effort. With only a few grease points—limited to tyres and suspension—the system eliminates the need for frequent servicing, saving you valuable time and reducing upkeep costs. This streamlined approach ensures dependable performance season after season, so you can focus on productivity rather than maintenance.
Advanced Suspension
The Unistack is engineered for stability and smooth operation, even in challenging conditions.

Combined with a hydraulically adjustable clamp height, the system easily accommodates bales of varying sizes, ensuring secure handling and maximum flexibility for different operations.
Easy Handling
Handling is effortless with the Unistack’s swinging drawbar, designed to deliver superior manoeuvrability and stability both in the field and around the stack. This feature provides operators with better visibility during unloading, making positioning and stacking safer and more efficient. Whether navigating tight spaces or working on uneven terrain, the swinging drawbar ensures smooth, controlled movement every time.
