Sumo or mzuri? Any good at following the ground? The rotation includes roots so ground is uneven. Currently plough/ deep tillage and power harrow. The power harrow has a front hopper so toying with the idea of a sumo toolbar DTS. This would let me put cover crops in without cultivation, and strip till after cover crops, from oats to wheat, from wheat to rye/ winter barley? Any thoughts? I feel we need to get the amount of time we spend on growing cereals down, although the ploughs and power harrow are bought and paid for? so dprcn is low along with work rate. Any comments.
