Craftsman Tractors are made by American Yard Products (AYP) which is owned by Electrolux (Swedish Corporation) which apparently is also the owner of Frigidaire and Eureka and several othe brand names. Ayp makes Craftsman, Husqvarna and Poulan Pro tractors and Weedeater trimmers and some Ryobi products.
MTD now makes Troybilt, Cub Cadet, White Outdoor, Yard Machines, Bolens,Toro and McCullogh chain saws.
Murray makes some John Deere rear engine mowers and snowblowers.
John Deere makes their own tractors In USA with some attachements made in Canada and some made in China.
Kubota is made in Japan and USA
I would rate the products thus:
Group A, Compact Tractors
1. Kubota (clearly the leader in engineering, quality and performance, especially since I own the very superior L-3130 with a LA723 loader and BH90 backhoe.
2. John Deere
3. The rest of the domestic and foreign tractor manufacturers.
Group B, Garden products
1. Kubota
2. Deere
3. Troybilt before MTD (I've owned a
chipper and rototiller)
4. AYP (since I own and have owned very dependable Craftsman tractors)
5. MTD
6. Murray
(Just my opinion)
