Product Details

This Kohler Command OHV Horizontal Engine with Electric Start gives you high power performance with overhead valve technology and a durable, long-life design with full-pressure lubrication. U.S.A.

Features + Benefits

  •  Hydraulic valve lifters are oil-pressurized, ensuring that push rods stay in constant contract with the rocker arms
  •  The valve train is virtually maintenance-free and requires no adjustment
  • Full-pressure lubrication delivers continuous lube to critical engine components, even at 25° angle of operation
  • Large capacity, in-line fuel filter provides extra protection against fuel line-clogging dirt particles
  •  Overhead valve technology provides greater volumetric efficiency and a higher compression ratio, providing more power, improved fuel economy, reduced oil consumption and better cooling
  • Virtually no carbon buildup for reduced maintenance costs
  •  The variable speed mechanical governor promises smooth performance, regardless of application or fluctuating demands for power
  •  The Kohler Command® electronic ignition system generates a stronger spark at lower cranking speeds and the Automatic Compression Release (ACR) system allows compression to escape during cranking to reduce pull force for reliable starts
  •  Easy maintenance, thanks to easy-access oil fill cap and dipstick handle and dual oil drains
  •  High power performance, with high-performance spark plugs, a 15 Amp regulated alternator and a large in-line fuel filter
  • Reliable, long-life design with hardened crankshaft journals, high-efficiency fan and screen, large dual-element air filter with foam pre-cleaner, cast iron cylinder liners and a spin-on, full-flow oil filter
  •  Quiet, smooth operation thanks to an engineered material blower housing and a mechanical fuel pump
  •  CARB and EPA-emission certified
  •  Smart-Choke® carburetor
  •  Electronic ignition system
  •  Solenoid shift starter
