Rhino CS177H HP 6:1 Gear Reduction Gas Engine
Recoil Start – 1" Horizontal Shaft
HIGHEST QUALITY GUARANTEED! Same day Shipping!
The Rhino CS177H 9HP Gas Engine from Carroll Stream Motor Company delivers high-torque performance in a simple, rugged package. With a 6:1 gear reduction and recoil pull start, this 270cc 4-stroke OHV engine is built for equipment that needs low-speed, high-power output—including hydraulic pumps, log splitters, sawmills, cement mixers, compactors, and augers. If you want dependable power without the added cost and complexity of batteries or wiring, the CS177H is a smart, budget-friendly choice.
The 6:1 gear reduction multiplies torque at lower RPM, giving you controlled power where it matters most. Rated at 9 HP @ 3600 RPM and up to 13.5 ft-lbs of torque @ 2500 RPM, the CS177H keeps equipment moving smoothly under load, shift after shift.
Simple, Reliable Recoil Start
The recoil pull start system is fast, dependable, and field-ready—ideal for remote jobsites or outdoor environments where electric start isn’t practical. Add fuel, set oil, a few pulls, and you’re on the job. A cast iron cylinder sleeve resists wear for long service life. Splash lubrication and forced-air cooling help protect internal components during extended operation, while low-oil shutdown safeguards the engine when oil levels drop.
Efficient, All-Day Runtime
A 1.58-gallon fuel tank supports extended operation with fewer stops. The 8.2:1 compression ratio and OHV design improve fuel efficiency without sacrificing output, helping control operating cost. The 1" keyed straight horizontal shaft (¼" keyway) with 3-1/2" total length (2-7/8" usable) integrates with a wide range of machinery. Compact 15" × 17" × 17" dimensions and a 55-lb dry weight make installation and service straightforward.
