⚙ From PTO to Tine Arm Drive \u2014 Rotary Rake Gearbox Anatomy<\/h2>\n

C\u1ee7a ch\u00fang t\u00f4i Rotary Rake agricultural gearbox<\/strong> is a specialized power transmission unit for hay raking:<\/p>\n

\n▶ PTO Power Input<\/summary>\n
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.<\/div>\n<\/details>\n
\n▶ Gear Reduction & Torque Multiplication<\/summary>\n
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.<\/div>\n<\/details>\n
\n▶ Output to Tine Arm Drive<\/summary>\n
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.<\/div>\n<\/details>\n
\n▶ Lubrication & Protection<\/summary>\n
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.<\/div>\n<\/details>\n
