Lcfman 4 #1 Posted May 1, 2025 I have a 310-8 I bought new in 1987. It’s been and still is a great piece of equipment. The only thing I have replaced is a carburetor a couple years ago and the mower deck belts(the main drive belt last year, can you believe the belts lasted that long). My question is there a direct 10 or 12 horsepower motor replacement. Share this post Link to post Share on other sites

Ed Kennell 44,089 #3 Posted May 1, 2025 (edited) Why are you looking for a replacement? Your tractor should have the Kohler Magnim 10 engine model number M10s-46152. The M10,12,14, and 16 should fit if from a gear drive. If from a hydro, you will need to change the pulley. Also may need to alter the belt guard for the 14 and 16.

Lcfman 4 #4 Posted May 1, 2025 The current and original engine is the Kohler 8 hp and I was looking to upgrade with a little more power. Share this post Link to post Share on other sites

If original your tractor is a 308-8 and gas tank is integral to the engine. Bigger engines you will have to get a fuel tank (under seat type) Edited May 1, 2025 by pfrederi Share this post Link to post Share on other sites
Ed Kennell 44,089 #6 Posted May 1, 2025 Can you post pictures of the tractors model plate and engine plate so we can determine if it is a 308-8 or a 310-8 Share this post Link to post Share on other sites
