Small Engines (Lawn Mowers, etc.)/Replace broken part


Hello Eric I have a ride on yardman 4140..14.76 And the wheel or disc with the fins on it is broke I think this fans the grass out to the side could you tell me what this part is called som I can order one.It is located just above the blade under the round grass canopy and has a steel centre with plastic disc that has chaneld fins which creates wind presure to blow the grass out.I can only discribe it as a bowler hat with an 8 inch rim with fins on the rim and a 1 inch   hole in the middle to fit on the down shaft that has the cutting blade atached to it hope I have explained the part good enough for you to recognise it thanks for your time and patience chris

If the fan you are talking about is on the engine then it is the fan, flywheel fan.  The URL below should take you to the engine parts diagram but check you engine model, type and code number to make sure they are correct.  The engine information is stamped on the engine shroud or valve cover.

This URL (below) is the parts diagram for your mower:

You machine is made by MTD but I can not find the model number in the US MTD website.  This is pretty common so you will need to search the UK website or another country.  The mower is similar to US MTD 13AL450C000.

Based on your description I am assuming you have a 30 inch deck and need part number 731-1583 (fan, deck), $90.00 US plus shipping and handling.

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.
