Hydraulic System

CONTROL VALVE

Hydra-Spread uses a custom-designed flow control valve for precise control of application rate. Engineered and manufactured exclusively for Hydra-Spread, the valve works well with all types of hydraulic systems and includes an internal bypass for quick return regardless of unloading speed. Like all Hydra-Spread components the valve is engineered and built for today’s powerful tractors.

HOSES & FITTINGS

All hoses and fittings are industry standard SAE (O-ring) or JIC (37 degree flare) fittings. There are no pipe threads. All hoses and fittings are rated for 3000 PSI operation.

Machines are supplied with poppet style ISO male tips from reputable North American suppliers such as Parker and Safeway.

Rubber hoses eliminate the corrosion problems that can destroy steel lines and, in the event of damage, can be easily replaced without ordering special parts.

HYDRAULIC CYLINDERS

Push-off cylinders are custom-engineered and manufactured to Hydra-Spread’s demanding standards. Like all Hydra-Spread hydraulic components, these cylinders are designed for 3000 PSI operating pressure. Our hollow rod design allows oil flow for extend and retract cycles to be channelled through the rod—eliminating the tangle of hoses that would hoses that would otherwise be involved when the cylinder strokes. The cylinder uses a rugged ball-type sealing system that easily handles the flexing that is inevitable in a cylinder with a fifteen foot stroke. Pistons and glands are high-grade ductile iron for maximum strength and wearability. The external oil conductor tubes are stainless steel.

For the endgate Hydra-Spread uses industry standard tie-rod cylinders. Like all our hydraulic components, these cylinders are designed for 3000 PSI operation.
