Capello Helianthus

Purpose and Design Features

The Capello Helianthus sunflower header is a specialized harvesting attachment designed for high-efficiency harvesting with minimal losses. Unlike universal grain headers, this model is engineered specifically to match the morphology of sunflowers. The primary design feature is the low-profile lifter design, which gently lifts the heads while minimizing seed shattering during the cutting phase. The rigid frame of the header ensures operational stability even at high combine speeds, eliminating vibration and misalignment.

Cutting System and Feeding Mechanisms

At the heart of the Capello Helianthus cutting system is a high-speed knife drive, which ensures a clean stem cut without pinching or shredding. The distance between the lifters is adapted to the average parameters of sunflower hybrids, allowing only the heads to be captured and fed into the auger. The height-adjustable, reel-like feeding drum ensures uniform mass flow into the combine's feeder house, preventing the formation of "dead zones" and the accumulation of crop residues, which is critical when harvesting in high-moisture or weed-infested conditions.

Drive and Power Transmission

The operation of the working parts is powered through reliable gearboxes and heavy-duty chain drives designed for peak loads. The design includes safety clutches that instantly disengage the kinematic chain if foreign objects are ingested, protecting the transmission from costly repairs. The use of components with a high safety factor allows the header to be operated in intensive agricultural cycles, reducing downtime for maintenance.

Hydraulics and Attachment

The Capello Helianthus stands out for its versatility in attachment: thanks to interchangeable adapter frames, the header is compatible with most modern combine models (John Deere, Case IH, CLAAS, New Holland). Control of hydraulic functions, such as the tilt angle adjustment and feeding drum positioning, is integrated into the combine’s electronic system. This allows the operator to respond promptly to changing harvesting conditions without leaving the cab, significantly increasing productivity throughout the workday.

Economic Efficiency and Loss Mitigation

The key advantage of this model is the minimization of harvest losses. Field trial data shows that the use of Helianthus helps reduce seed losses to 1–1.5%, even in over-dried crops. Due to the specific geometry of the pans, seeds that fall out of the heads during cutting are directed into the auger area rather than onto the ground. The economic return from using this equipment is reflected in the increase in net yield per hectare, making the investment in this model justified for operations with large sunflower acreages.

Maintenance and Reliability

Capello engineers have paid particular attention to the accessibility of friction points and adjustment mechanisms. Easily removable protective covers allow for quick inspection of chains and knife drives. The use of wear-resistant materials in the production of the lifters increases intervals between scheduled repairs. In field conditions, this means lower costs for consumables and the ability to perform maintenance with in-house mechanics without the need for specialized external personnel.

Application and Adaptation

The header effectively handles both classic, short, and tall sunflower hybrids. It is equally productive when working with narrow and wide row spacing, as the lifters are not tied to a specific planting pattern. The header’s ability to operate at high speeds without sacrificing quality makes it indispensable for large-scale agricultural enterprises where timely harvest completion is critical. The Helianthus model is a choice for professionals focused on maximizing the output from every hectare of sunflowers.
