I only have about one acre of garden, the garden is for my use only. Need a gt to use a tiller up to 4ft no bigger though. buying used probably older. don't want to spend much. right now choices seem to be a 400 jd with a belt tiller or a case 446 with hyd. tiller. Kinda looking for price i should be paying. pretty sure there both from the 80's. both are in decent shape with a lot of hours. Prices i should pay? should i look at something else?
