PowerStroke Subaru 21" Self Propelled Mower

Boxer jokes aside, what engine does this use? Briggs or something else?

As the listing says, it uses a Subaru engine. Subaru actually makes small engines but they aren’t very well known. http://www.subarupower.com/products/engines/ea175v-overhead-cam-vertical-shaft-engine/

Did your order include a key?

Didn’t see a key in mine. With as rough shape as the box arrived in it probably fell out somewhere in FedEx’s shipping system. Will see how calling customer support about that goes tomorrow, I guess.

As others have noted, shipping company’s box leaves something to be desired. No key, called the CS number and they shipped me 2 keys.

Works fine, but I would buy the $299 new one from HD, rather than the refurb.
