Need a replacement engine for your Toro equipment? This is a brand-new, genuine Kohler CH740-3357 (Rehlko spec PA-CH740-3357) 25 HP Command PRO horizontal-shaft engine — the engine spec used on Toro machines.

Before you order: confirm fitment

  • Check the engine tag on your Toro machine: it should read CH740-3357 / PA-CH740-3357 or an older spec this engine replaces (CH740-3213).
  • 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.
