Specifications

  • Our Briggs & Stratton 40U8770026G1 656cc engine is fully compatible as a replacement for the Briggs & Stratton 40H777-0241-E1 656cc engine on the CRAFTSMAN GT 5000 917.275970 mower.
  • Important Note:
  • If your engine’s model number starts with "40", this indicates a 656cc displacement. Both your original engine and our replacement share this same displacement, ensuring a proper fit and reliable performance.
  • Our replacement engine provides 20 Gross HP, which is more than sufficient to power your equipment effectively. If you're comfortable with a small variation in horsepower—whether slightly more or less—you can proceed with confidence.
