Rotary Cutter PTO Gearbox Overview<\/h2>\n

The EP-RC61T is a versatile rotary cutter PTO gearbox<\/b> built for brush hog and rotary cutter applications requiring up to 60 HP of PTO input power. What distinguishes this PTO\u30ae\u30a2\u30dc\u30c3\u30af\u30b9<\/b> from single-ratio units is its availability in four gear configurations \u2014 1:1, 1:1.21, 1:1.46, and 1:1.93 \u2014 achieved through different tooth count combinations on the spiral bevel gear pair. This allows operators and equipment manufacturers to match the gearbox output speed precisely to their specific cutter head design and vegetation conditions. At 540 RPM input, the four ratio options deliver output speeds ranging from 540 RPM (direct drive) up to approximately 1,042 RPM (at 1:1.93), covering the full range that standard rotary cutters need for grass, brush, and light timber clearing.<\/p>\n

\u306e PTO\u30ae\u30a2\u30dc\u30c3\u30af\u30b9<\/b> weighs 33.5 kg \u2014 a mid-weight category that reflects the 60 HP power rating and the heavy-gauge cast iron housing required for rotary cutter service. Both input and output shafts use a 1 3\/8-inch, 6-spline (Z6) connection, which is the standard PTO interface across virtually all \u30c8\u30e9\u30af\u30bf\u30fcPTO\u30ae\u30a2\u30dc\u30c3\u30af\u30b9<\/b> applications in the 30-75 HP range. This standardization means the EP-RC61T can be fitted to a wide variety of rotary cutter brands and PTO\u30ae\u30a2\u30dc\u30c3\u30af\u30b9<\/b> configurations and models with minimal or no modification.<\/p>\n
