I mold board plow then disc harrow and then planter for my corn,beans peas etc. works perfect. The part of the garden that I plant my small seeds in get's a pass with the front tine tiller then use a small earth way planter.
I use all 50's era Farmall Super C's w Fasthitch implements. With the exception of the tiller.
My buddy does a big garden with a 6' 3ph tiller an it takes several hours to till. Point is a tiller is a lot slower than plowing and discing.
