Rake Tines and Springs: Maximizing Hay Harvesting Efficiency

Learn how rake tine quality affects forage cleanliness. The Agrokron guide to maintenance for fast, waste-free hay harvesting.

Rake Tines and Springs: Maximizing Harvesting
Hay season is a race against time and changing weather conditions. A rake that loses its rhythm or leaves product in the field due to worn-out tines represents more than just an operational slowdown—it is a direct financial loss in forage quality. In this Agrokron technical guide, we explore why choosing the right replacement parts is the first step toward professional, high-efficiency hay harvesting.

The Science of Contact: Why the Tine Makes the Difference

The rake tine is the primary interface between your machinery and the field. Often underestimated, its role is critical: it must collect forage with millimeter precision without damaging the turf. Low-quality tines or those made from improper alloys suffer from "permanent set" (they bend and do not return to their original position), causing uneven collection. This phenomenon inevitably leads to the loss of alfalfa or clover leaves, which are the most protein-rich parts of the harvest. Our replacement parts, selected to meet OEM specifications, guarantee superior elasticity, allowing the tine to adapt perfectly to ground irregularities.

💡 Technical Tip: The Importance of Coil Profile Don't just replace broken tines. Observe the coil mounting point: if you notice deep oxidation or signs of micro-cracks on the spring, the entire set is at risk. Metal fatigue is invisible but lethal during long night shifts or high-speed operations.

Preventing Contamination

A well-equipped rake is not just faster; it is cleaner. Worn tines or those with incorrect angles tend to "attack" the soil, picking up stones, dirt, and impurities. Beyond damaging the final quality of the hay and increasing wear on the following baler's blades, the presence of dirt in the forage drastically increases the risk of bacterial contamination (such as Clostridium), which can compromise the entire silage fermentation process or the storage of dry hay.

Preventive Maintenance: Protecting the Tine Arm

Vibration is the silent enemy of every rake. A balanced and correctly installed set of tines reduces harmonic stress that transmits to the tine arms and, consequently, to the machine's gearboxes. Investing in a new set of tines before the season begins means extending the service life of the entire drive system, avoiding costly downtime and complex structural repairs during peak harvest.
