Rotary Rake application

⚙ From PTO to Tine Arm Drive — Rotary Rake Gearbox Anatomy

Unser Rotary Rake agricultural gearbox is a specialized power transmission unit for hay raking:

▶ PTO Power Input
The gearbox input shaft connects to your tractor’s PTO via a splined coupling (6-spline at 540 RPM or 21-spline at 1000 RPM). Precision double-row tapered roller bearings absorb the combined radial and thrust loads generated during hay raking. On this raking implement, the PTO driveline feeds energy into the gearbox at the rotary rake’s primary drive point.
▶ Gear Reduction & Torque Multiplication
The heart of the gearbox is a matched set of herringbone gears, forged from Cr-Mo alloy steel. These gears reduce rotational speed from PTO RPM to the tine arm drive’s working speed while proportionally multiplying torque. The rotary rake gearbox drives one or more large tine arms that sweep cut hay into windrows. Mounted at the top of the rake mast, it converts PTO input into the circular sweeping motion of the rake arms while maintaining consistent ground-following through varying terrain. The gear mesh geometry is computer-optimized for even load distribution.
▶ Output to Tine Arm Drive
The gearbox output shaft connects directly to the rotary rake’s tine arm drive, delivering torque-multiplied power for productive hay raking. The output coupling is machined to precise tolerances for responsive, zero-backlash power delivery.
▶ Lubrication & Protection
A multi-layer protection system extends service life: ductile iron housing resists impact and corrosion, mechanical face seals block contaminants, full-synthetic 75W-140 maintains hydrodynamic film on all surfaces, and a breather vent equalizes pressure during temperature changes.

📝 How to Install Your New Rotary Rake Agricultural Gearbox

This guide covers the complete process of replacing the gearbox on your rotary rake. Each step includes specific details for hay raking equipment — follow them in sequence for best results.

Step 1 — Connect PTO Driveline

Schieben Sie die Zapfwellen-Antriebswelle über die Getriebeeingangsverzahnung. Achten Sie auf vollständigen Eingriff – die Welle sollte über die Haltenut gleiten und einrasten. Prüfen Sie den Eingriff durch kräftiges Ziehen an der Welle; sie darf sich nicht lösen. Stellen Sie sicher, dass die Antriebswellenlänge einen ausreichenden Teleskophub über den gesamten Bewegungsbereich des Anbaugeräts ermöglicht.

Step 2 — Prepare the Mounting Surface

Scrape any old gasket material or RTV sealant from the rotary rake’s gearbox mounting face. Use a flat file to remove any burrs around bolt holes. Verify all mounting holes align correctly by test-fitting the new gearbox without bolts. Check for flatness — a feeler gauge should show less than 0.1mm across the mounting surface.

Schritt 3 – Testlauf & Einfahren

With the rotary rake raised or in a safe test position, start the PTO at idle speed. Observe the gearbox for any vibration, unusual noise, or oil seepage. Run for 20 minutes at reduced speed. If all is normal, increase to the operating PTO speed and run for an additional 10 minutes while monitoring temperature. Re-check all mountings.

Step 4 — Remove Old Gearbox

Detach the driveline yoke from the gearbox input. If the gearbox also has an output coupling to the tine arm drive, disconnect that as well. Support the gearbox from below with a hydraulic jack. Remove the mounting fasteners progressively, keeping at least two bolts finger-tight until you are ready to slide the unit out.

Step 5 — Drain & Document Old Gearbox

Stellen Sie eine Auffangwanne unter das Getriebe. Entfernen Sie sowohl die Einfüll- als auch die Ablassschraube, um das Ablassen des Öls zu beschleunigen. Fotografieren Sie während des Ablassens das Typenschild des Getriebes, die Befestigungsanordnung und den Antriebsstranganschluss – diese Bilder sind bei Fragen während des Einbaus des neuen Getriebes von unschätzbarem Wert.

Step 6 — Connect Output to tine arm drive

Connect the output coupling to the tine arm drive drive on your rotary rake. Ensure the shaft engagement depth meets the minimum specified in the manual. Tighten all retaining hardware to the correct torque value. After connection, rotate the output by hand to verify smooth, unrestricted movement.

Step 7 — Safety Preparation

Position the rotary rake on a flat, stable surface and immobilize the tractor. Disengage the PTO and shut down the engine. Remove the ignition key to prevent accidental start-up. Wait at least 15 minutes for hot surfaces to cool. Gather your tool kit: socket set, torque wrench, clean containers for oil, and the installation manual.

Step 8 — Post-Installation Checks (10-Hour Service)

Führen Sie eine 10-Stunden-Wartung durch: Überprüfen Sie das Anzugsmoment der Befestigungsschrauben, suchen Sie nach Leckagen, kontrollieren Sie den Ölstand und stellen Sie sicher, dass die Zapfwellen-Schutzvorrichtung angebracht ist. Entfernen Sie jegliche Ablagerungen vom Getriebegehäuse, um eine effektive Wärmeableitung zu gewährleisten. Dokumentieren Sie die Installationsdetails in Ihren Wartungsunterlagen.

⚠ Wichtig: Arbeiten Sie aus Sicherheitsgründen niemals unter ungesicherten Geräten. Verwenden Sie beim Umgang mit dem Getriebe geeignete Hebezeuge.

🔎 Diagnostic Checklist — Rotary Rake Gearbox

Even the best-engineered gearbox may encounter operational issues over its service life. This guide covers the most common symptoms reported with rotary rake gearboxes and provides actionable field solutions.

⚠ Übermäßige Vibrationen während des Betriebs

Wahrscheinliche Ursache: Loose mounting bolts allowing gearbox movement

Was zu tun: Vibration in a rotary rake gearbox system usually originates from the driveline, not the gearbox itself. Inspect the PTO shaft U-joints — a worn joint creates a twice-per-revolution vibration pulse. Confirm the driveline is the correct length for the tractor-to-implement distance. Re-torque the gearbox mounting bolts.

⚠ Öl tritt an den Wellendichtungen aus

Wahrscheinliche Ursache: Blocked breather vent preventing pressure relief

Was zu tun: Überprüfen Sie die Entlüftungskappe – eine verstopfte Entlüftung setzt das Gehäuse unter Druck und drückt Öl an den Dichtungen vorbei. Ersetzen Sie die Entlüftung und entfernen Sie jegliche Ablagerungen. Wenn die Undichtigkeit weiterhin besteht, ersetzen Sie die betroffene Dichtung. Prüfen Sie die Wellenoberfläche unter der Dichtung auf Riefen oder Korrosion, die die Dichtlippe beschädigen könnten.

⚠ Gearbox Produces a Metallic Clunking Sound on PTO Engagement

Wahrscheinliche Ursache: PTO driveline too long, causing impact on engagement

Was zu tun: Check the PTO driveline length — a driveline that is slightly too long will ‘bottom out’ on engagement, creating a sharp metallic sound. Verify all external hardware (mounting bolts, guard brackets, driveline clamps) is secure. If the sound comes from inside the gearbox under load, internal inspection is recommended.

⚠ Schwierigkeiten beim Verbinden des Nebenabtriebsstrangs mit dem Getriebe

Wahrscheinliche Ursache: Damaged or worn PTO yoke engaging surface

Was zu tun: Tragen Sie Kriechöl auf die Eingangsverzahnung auf und lassen Sie es 5 Minuten einwirken. Drehen Sie die Zapfwellenwelle leicht unter leichtem Druck – die Verzahnung muss vor dem Eingriff einrasten. Ist die Antriebswellengabel verschlissen, ersetzen Sie sie vor dem Einbau, um vorzeitigen Ausfall des Eingangslagers zu vermeiden.

⚠ Ungewöhnliche mahlende oder heulende Geräusche

Wahrscheinliche Ursache: Bearing wear or race damage

Was zu tun: Check oil level immediately — low oil is the most common cause of gear noise in rotary rake gearboxes. If oil level is correct, the lubricant may have degraded — perform a complete oil change. Persistent noise indicates internal wear requiring professional assessment.
