Synchronous hydraulic cylinders for precision planting.

Helesul synchronized hydraulic cylinders are widely used in raising and lowering planting rows, simultaneously controlling all planting units to ensure seeds are deposited at the same depth across the entire bar. Its application is essential in high-precision crops such as soybeans, corn, and cotton, where uniformity of emergence directly determines final productivity. The system also operates in controlling furrow openers on irregular terrain, maintaining constant depth even on undulating slopes while automatically compensating for height variations.

Working together with load sensors, the cylinders adapt compaction wheel pressure according to soil variation, optimizing seed-to-soil contact without excessive compaction. They also synchronize the vertical movement of fertilizer and inoculant reservoirs in fertilizer carts, preserving set stability during curves and maneuvers. In large-capacity planters, they allow coordinated tilting of hoppers to facilitate refueling and maintenance, with integrated hydraulic safety locks.

The integrated mechanical synchronization system ensures simultaneous and proportional movement of all cylinders, eliminating height differences between planting rows that compromise emergence uniformity. Progressive damping reduces impacts on irregular terrain, protecting planter structures and increasing the service life of mechanical components by up to 40%, resulting in lower maintenance costs throughout the planting season.

The dual sealing system with reinforced scrapers prevents penetration of dust, soil, and crop residue, maintaining operational efficiency even under severe field conditions throughout the entire planting season. Fine depth adjustment allows micrometric regulation via centralized hydraulic control, optimizing seed placement according to soil type and humidity, quickly adapting to changing operational conditions.

Modular step-mounted design facilitates installation on planters from 5 to 36 rows, adapting to different configurations without requiring custom components, reducing integration time and cost. The intelligent bypass system protects the circuit against overpressure from obstacles such as rocks and stumps, diverting flow instantaneously and resuming normal operation automatically, preventing hydraulic damage during field operations.
