Ocmis Linear

Overview

The Ocmis Linear is a self-propelled linear move irrigation system engineered by OCMIS Irrigazione S.p.A., Italy's premier manufacturer of precision irrigation equipment. This advanced linear pivot features a central motor drive configuration with a self-moving boom specifically designed to maximize irrigation efficiency on rectangular and irregularly shaped fields. The system can draw water from either a flexible hose supply or an irrigation channel, providing exceptional operational flexibility for diverse farming environments and water infrastructure scenarios.

What distinguishes the Linear from conventional pivot systems is its unique linear travel pattern combined with a central motor positioning that delivers superior weight distribution and structural stability during operation. This Italian-engineered irrigation machine represents decades of OCMIS innovation in mechanized irrigation technology, offering farmers a reliable solution for uniform water application across large rectangular parcels where traditional center pivots would leave significant areas unirrigated. The Linear's self-propelled boom design eliminates the need for complex external power sources while maintaining precise water distribution throughout the field.

Ocmis Linear Pivot

Key Features & Benefits

Central Motor Configuration: Provides balanced power distribution along the boom structure, reducing stress points and extending equipment lifespan while ensuring consistent travel speed across varying terrain conditions.
Self-Moving Boom Design: Eliminates reliance on external towing equipment or manual repositioning, significantly reducing labor requirements and allowing for automated irrigation scheduling with minimal operator intervention.
Dual Water Supply Compatibility: Accommodates both hose-fed and channel-fed water delivery systems, enabling farmers to adapt the irrigation system to existing infrastructure without costly modifications or water supply redesign.
Rectangular Field Optimization: Purpose-built linear travel pattern maximizes irrigated area on rectangular parcels, eliminating the corner waste inherent in circular pivot systems and increasing total productive acreage.
Italian Engineering Quality: Manufactured by OCMIS Irrigazione S.p.A. in Italy with precision components and corrosion-resistant materials that withstand demanding agricultural environments and deliver decades of reliable field performance.
Scalable System Architecture: Modular design allows for customization of boom length, hose diameter, and raingun configurations to match specific field dimensions, crop water requirements, and available water pressure conditions.

Ideal Applications

Rectangular Field Irrigation: Maximizes water coverage on rectangular parcels where traditional center pivots would leave significant corner areas unirrigated, improving overall field utilization and crop uniformity.
Row Crop Production: Ideal for irrigating corn, soybeans, wheat, and other row crops planted in straight-line patterns, allowing the linear travel to follow planting rows without damaging plant canopy.
Vegetable Farming Operations: Provides consistent water application for commercial vegetable production requiring precise moisture management throughout rectangular growing blocks or greenhouse supplement irrigation.
Pasture and Forage Management: Efficiently irrigates rectangular pasture sections and forage crop fields, supporting intensive grazing operations and hay production with programmable watering schedules.
Challenging Terrain Configurations: Accommodates irregularly shaped properties, fields bordered by roads or structures, and parcels where circular pivot swing would conflict with boundary constraints or adjacent land uses.
Channel-Based Irrigation Districts: Integrates seamlessly with existing irrigation channel infrastructure in agricultural districts, drawing water directly from concrete or earthen channels without requiring pressurized pipeline installation.
