Kohler CH680-3044 22.5HP 674cc V-Twin Engine – 1-1/8in Shaft, Electric Start

Description

Displacing 674cc across two cylinders, the Kohler CH680-3044 horizontal V-Twin engine sustains uninterrupted cutting torque under heavy commercial brush chipping loads. Tree service contractors face severe mechanical stress when branch feed rollers jam, which twists undersized drive shafts and cracks lightweight crankcases. This 22.5HP Command PRO engine features an oversized 1-1/8-inch output shaft and a forged steel crankshaft engineered to absorb severe rotational shock loading.

Dual cylinder cast-iron sleeves protect internal tolerances against bore wear, keeping oil consumption low across hundreds of chipping hours. Full-pressure lubrication circulates filtered motor oil directly to high-load rod bearings and valve gear, ensuring uninterrupted fluid barrier protection during continuous full-throttle operation. The commercial-grade carburetor meters fuel with precision across varying load demands, preventing engine hesitation when chippers feed heavy hardwood limbs.
