Question
Just bought a 1999 cub cadet 2155 with 15hp. i have a older hds 2185 with 18hp Kohler command. Can I replace the 15 with the 18?

Answer
It should bolt right on but you should measure the crankshaft diameter (length and diameter) as well as the engine dimensions to make sure it will fit under the hood.

Other things to check are the throttle control connection, wiring, and fuel line routing.

If they are both Kohler the swap should be pretty easy as long as the engine pulley comes off with out a fight.

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
