Small Engines (Lawn Mowers, etc.)/dynamow ds


Hi. I'm looking for help regarding a Dynamow ds lawn mower. I have recently bought a second hand one and on first use unfortunately it dropped the bolt which goes through the blade and clutch into the bottom of the engine. I have tried to find it on the lawn and cannot find it anywhere. Would you be able to advise where I could possibly find a part number or parts list for this as my searches on the Internet are coming up empty.

Many thanks
Simon Bruce

Did you check this link:

Since I haven't seen Dynamow brand mowers in the US I'm not exactly what size fasteners they use on their products.

You could make a template of the bolt diameter out of a dowel rod, some drinking straws taped together or any other round material to get a rough idea of the fastener diameter and length.  Then you could go to your local hardware supply store and purchase a couple of fasteners and see if they fit.

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.
