Which of these is the agricultural equipment used for secondary tillage?

I always feel for the farmers, the hard work they do, the reliant on nature…to give enough for their crops or livestocks to survive

Tom, I agree. It depends on climate how you cultivate! in the UK I made water shedding humps. Manure on the top to wash down to the edges. Bulgaria make troughs!

Excessive tillage and cultivation of soil is frowned upon in Australia. It reduces soil moisture and increases wind erosion.
