Need a replacement engine for your Exmark Lazer Z AS LZAS25KC604 zero-turn mower? This is a brand-new, genuine Kohler CV742-3037 (Rehlko spec PA-CV742-3037) 25 HP Command PRO vertical-shaft engine with a 1-1/8" x 4-5/16" crankshaft — the engine spec used on Exmark machines such as the Lazer Z AS LZAS25KC604.

Kohler Engines now operates as Rehlko; same engine, same factory, same part number. Ships new in the crate with the manufacturer's engine warranty.

Before you order: confirm fitment

  • Check the engine tag on your Exmark machine: it should read CV742-3037 / PA-CV742-3037 or an older spec this engine replaces (CV740-3117, CV742-3014).
  • Match crankshaft diameter and length, mounting pattern, PTO/clutch, fuel and wiring connections.
  • Not sure which engine your machine has? Call (646) 666-7225 with your machine model and serial number and we'll confirm the right spec.
