When we were kids my dad had a couple David Bradley tractors. In 1959 he bought a new David Bradley Suburban model for yard and garden work. It came From the Sears Farm Store in a crate with "some assembly required". He also bought a bunch of accessories including a 48" mower, 10" mold board plow, a disc, cultivator, wheel weights, and 42" dozer blade.
The other David Bradley was much like the one the OP owns. My dad actually traded a horse for it. We had the horse a few years, but as we got older the girls got more attention than the horse, so it was time to let him go. The walk behind tractor only had a plow and disc, and was a beast for us kids to operate so after a few years it also went down the road to another family
The Suburban spent the spring preparing the 1 acre garden with the plow and disc. In the summer it mowed another acre of grass plus cultivating the garden. In the winter it plowed snow. Even though it only had a Briggs 5.75 hp engine it never seemed to lack power. It was a bit light however trying to move a foot of snow. We learned quickly when plowing snow the first snowfall should be pushed far beyond the actual edge of the drive. After it thaws and freezes a few times there's no way that little tractor is going to move it again.
That tractor worked on an almost daily basis for over 20 years. After my dad passed my mother gave up on the big garden and only used it to mow grass. By now she had a snow blower which made keeping the drive open a much easier job. The tractor was finally sold to a collector along with all the accessories when she moved to Florida. The 40+ year old snow blower stayed in the family and finally gave up the ghost about 3 years ago.
