They were a well known manufacturer of reel mowers but may be gone. Would be an interesting project.

This is a rotary mower. I wish somebody knew something about it. Maybe some info on a briggs 3.5 would help. I'll probably go get it tomorrow. I hope it is still on the curb.

Some parts are still available, hope you weren't too late picking it up....

Probably much, mush too late to be of help or interest, but the mower on the curb sounds like the type we, or I should say my grandfather had for his lawn care and gardening business. They were VERY reliable and easy to work on. The motor screwed to the deck and entirely exposed with easy access to air cleaner, and carb. The deck was cast aluminum. I wish I still had the one that came to me for my first house.

About 18 years ago there was a lady in the neighborhood who put this lawnmower out by the street. I asked her what was the story on it, she said she just wanted rid of it so I took it and put it in the shed and didn't think twice and actually thought it was a snapper lawnmower. In the process of moving and my other mowers are in Florida now so pulled out this mower and figured I would see if it would start. I went and got a new plug and filter at Walmart and to my surprise it started on the second pull. I took it out for a "test mow" and couldn't believe how easy it was to push. One of the other mowers is a front wheel drive and the cooper is easier than that one. I read the story where the workers unionized and the company shut down. Today we see fast food workers wanting 15 an hour where soldiers and EMT's don't make that. And like the former cooper employees it seems now Wendy's and McDonald's is looking to put in touch screen kiosks so history repeats.

I worked in a shop in the early '70's that sold and service Cooper lawn mowers. As previous posters have said, they used high quality, cast aluminum decks and were available as push or self-propelled models. The self-propelled units had a two speed chain drive that used a derailler to shift (like a 10 speed bicycle) and a very unique double drum clutch. The B & S 3.5HP engine was the weak link in an otherwise excellent lawn mower. I think these may have been some of the earliest all-aluminum engines. They ran OK but the slightest bit of dirt that got past the air cleaner would score the cylinder and now you had a built-in mosquito fogger! Still, it was a well designed unit--a shame what happened to the company.
