I have experience using a land pride tiller 5ft. behind my TO-35 Ferg.
do not know the price point compaired to the brand you are looking at, but the land pride tiller did a great job, gardens looked great after tilling.
it was heavy built, had a good slip clutch as i caught a root/rock in the tines more than once and clutch just slipped.
as i said, i just borrowed it, neighbor moved, so i lost my tiller access, but someday i would like to own one.
Note to self: when you own a tractor tiller, you will have a lot of new friends you did not know you had, but they will want to borrow the tiller.
how do i know: i bought a 3pt hitch post hole digger, it's loaned out, as we speak, to a friend!!!!!!!
