1-1/8" x 4-5/16" Keyed Shaft | Electric Start | Fits Exmark / Toro E3

The Rehlko Command Pro CV742-3000 is a commercial-grade 25 HP V-Twin small engine built for demanding equipment that requires dependable power, long service life, and strong replacement compatibility. Previously known under the Kohler name, this 747cc 4-stroke OHV V-Twin engine is designed for a wide range of commercial, residential, and industrial applications, including mowers, generators, saws, utility equipment, and specialty machinery.

This engine features a 1-1/8" diameter straight keyed shaft, 1/4" keyway, and 4-5/16" total shaft length, making it a strong fit for equipment requiring this specific output configuration. The electric start system with 12-volt heavy-duty starter provides dependable starting performance, while the 20 AMP charging system with regulator supports battery charging and compatible electrical accessories.

The CV742-3000 is engineered for durability in tough working conditions. Its pressure lubrication system helps protect internal components during extended operation, while the integrated oil cooling design helps control operating temperatures and support longer engine life. A heavy-duty air cleaner helps keep debris out of the engine, improving reliability in dusty commercial and industrial environments.

This model is a strong replacement choice for equipment using Exmark / Toro E3 engine setups and supersedes several earlier Kohler and Rehlko models, including CV682-3013, CV742-3014, CV742-3037, and CV742-3135. It is also cross-referenced with Briggs & Stratton 49T877, making it a useful option for equipment owners and repair professionals seeking a durable, rebuildable replacement engine.
