Good morning, all. Could I please get some recommendations for lawn mower repair places in the Waldorf area? A lot of white smoke is coming out of the mower, the engine is doing a lot of knocking, and it's leaking oil. I found four companies online, but I wanted to wait to see if any forumites had had good or bad experiences with their repairs. The companies are Tool Solutions, Rusty's Mower Repair, Alex's Mobile Repair, and Mower Medic. Also, if you think it would just be better to buy a new mower, please let me know that too. My present mower is five years old. Thanks in advance for any help.
