Model: EP-RC61T \u00a0\u00b7\u00a0 Ratios: 1:1 to 1:1.93 \u00a0\u00b7\u00a0 Replaces Omni Gear RC-61T \u00a0\u00b7\u00a0 For 10 ft+ Multi-Deck Mowers<\/p>\n

What Is the EP-RC61T Rotary Cutter Gearbox?<\/h2>\n

The EP-RC61T<\/strong> is a T-configuration splitter gearbox for wide-cut rotary cutters and mowers with two blade decks. It takes one 540 RPM PTO input and distributes power to both outer right-angle gearboxes simultaneously \u2014 no second shaft run required. If your machine has a 10 ft or wider cut width with two separate deck sections, this is the replacement gearbox for rotary cutter<\/em> that holds the system together.<\/p>\n

Built to replace the Omni Gear RC-61T, the EP-RC61T uses 20CrMnTi alloy steel gears<\/strong> ground to Grade 5\u20136 precision (HRC 58\u201362 surface hardness) and 42CrMo alloy steel shafts<\/strong> (HRC 25\u201330). Transmission efficiency is 98%<\/strong> at rated load. Noise stays below 68 dB<\/strong> and vibration at \u2264 20 \u00b5m<\/strong>.<\/p>\n

Four gear ratios (1:1 \/ 1:1.21 \/ 1:1.46 \/ 1:1.93), a 4-bolt 3-1\/4″ \u00d7 5″ mounting pattern, and 1-3\/8″ 6-spline shafts match OEM RC-61T dimensions exactly \u2014 zero machining or adapters needed. A reliable choice for dealers, OEM assemblers, and fleet operators sourcing a slasher gearbox<\/em> at scale.<\/p>\n
