That would not work the B. It would be next to driving without anything behind it at all. The neighbor pulls a 4 foot cheaper brand with his old Cub Cadet lawn mower. As far as that brand I have only seen the TV ads. The B is a lot stronger tractor than most think. The nice thing about the self powered pull behind mowers is that you can back into corners for better trim.
What you will find is that you will need a B to mow your lawn. You will need a B to mow the pasture. You will need a B to plow the garden. You will need a B to fit the garden and another one to cultivate the garden.
A person in this day and age just can not afford to waste B driving time changing from one tool to the other. Unless you are really lazy like me you could use the same B that you fit the garden with to pull a trailer.
By deleting this foot note you might be able to get your wife to consent to at least one more. (:^D
