Need a replacement engine for your Scag equipment? This is a brand-new, genuine Kohler CH730-3254 (Rehlko spec PA-CH730-3254) 23.5 HP Command PRO horizontal-shaft engine with a 1-1/8" x 3-5/32" crankshaft — the engine spec used on Scag machines.

Before you order: confirm fitment

  • Check the engine tag on your Scag machine: it should read CH730-3254 / PA-CH730-3254 or an older spec this engine replaces (CH730-0066).
  • 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.
