Clean Sweeps, Quality Silage: PTO Drive Shafts for Hay Rakes<\/h1>\n

In the Netherlands, grass is gold. High-quality silage is the foundation of the dairy industry. When the weather window opens, contractors (“loonwerkers”) move fast. Rotary Rakes (harken) and Tedders (schudders) work long hours, covering hundreds of hectares of uneven polder land. The PTO shaft driving these machines faces a unique challenge: Maneuverability<\/strong>.<\/p>\n

Unlike a plow that works in straight lines, a rake is constantly turning at the headlands, navigating around ditches (sloten), and folding for transport. The driveline must accommodate these extreme angles without “chattering” or damaging the input gearbox. A seized u-joint or a failed torque limiter can leave rows of cut grass rotting in the rain.<\/p>\n

Hos EVER-POWER har vi konstruert “H-Rake” Series<\/strong> specifically for the dynamic demands of grassland machinery. We focus on lightweight, wide-angle capabilities and reliable torque protection to keep your harvest moving.<\/p>\n

\ud83c\udf3e Grassland Specialist Report: The Headland Turn<\/h3>\n

Sted:<\/strong> Dairy Farm, Friesland
\nUtstyr:<\/strong> 2-Rotor Side Delivery Rake<\/p>\n

“I observed a contractor raking silage. Every time he turned at the headland, the rake’s safety clutch would ratchet loudly, ‘Click-Click-Click’. He ignored it, saying, ‘it always does that.<\/p>\n

This is a classic error. The clicking meant the standard PTO shaft was binding due to the sharp angle (over 45 degrees), causing torque spikes. This wasn’t just annoying; it was fatigue-stressing the rake’s main gearbox input shaft.<\/p>\n

L\u00f8sningen:<\/strong> We upgraded the tractor-side connection to a Wide-Angle (CV) Joint<\/strong>. This allows smooth power transmission up to 80 degrees. The clicking stopped immediately. The operator could turn tighter and faster without disengaging the PTO, saving valuable time per hectare and protecting the gearbox.”<\/p>\n<\/div>\n

Technical Superiority: Engineered for Agility<\/h2>\n

Raking and tedding require a driveline that is flexible yet protected.<\/p>\n

1. Wide-Angle (CV) Freedom<\/h3>\n

Dutch fields are often small and irregular, bordered by canals. Tight turns are inevitable. Our shafts feature 80\u00b0 Constant Velocity (CV) Joints<\/strong>. This technology eliminates the “velocity fluctuation” (speed pulsing) that occurs with standard U-joints during turns, ensuring the rake rotors spin at a constant speed for a uniform windrow.<\/p>\n

2. Ratchet Torque Limiters (The “Clicker”)<\/h3>\n

Rakes are prone to hitting obstacles\u2014earth lumps, fence posts, or old tires on the silage clamp. We use Automatic Ratchet Clutches (SA Series)<\/strong>. When torque exceeds the limit (e.g., rotor hits a mound), the clutch slips with an audible noise but re-engages automatically once the load drops. No shear bolts to replace, no stopping the tractor.<\/p>\n

Client Success Story: The Tedder Solution<\/h4>\n

Klient:<\/strong> Organic Dairy Farm, Utrecht
\nUtfordring:<\/strong> Using an 8-rotor tedder. The outer rotors were vibrating violently, and the PTO shaft connecting the tractor was overheating. The standard “Lemon” tube was twisting under the startup load of 8 rotors.<\/p>\n

EVER-POWER-l\u00f8sning:<\/strong> We upgraded the main drive shaft to a Star Profile Tube (S4),<\/strong> which has 40% higher torsional rigidity. We also added an Overrunning Clutch (RL)<\/strong>. The overrunning clutch allowed the heavy rotors to spin down freely when the tractor stopped, preventing the momentum from pushing the tractor forward.<\/p>\n

Utfall:<\/strong> Vibration eliminated. Safer operation for the driver, and extended life for the tractor PTO brake.<\/p>\n<\/div>\n

Regional Relevance: Safety for the Lone Operator<\/h2>\n

Raking is often done by younger operators or seasonal help. Safety is non-negotiable.<\/p>\n

V\u00e5re sjakter har “Full-Coverage” Guarding<\/strong> that completely encloses the wide-angle joint. The guard cones are made from a flexible polymer that resists cracking if stepped on. We use robust anti-rotation chains with quick-clips to ensure the guard is always secured, meeting strict Dutch safety regulations.<\/p>\n

The Rotor Driver: Agricultural Gearboxes for Rakes<\/h2>\n

The PTO shaft gets the power to the machine, but the Girkasse<\/strong> distributes it to the rotors. In a rake or tedder, the gearbox network is complex, often involving a main splitter box and individual rotor drives.<\/p>\n
