The implement certainly IS being drawn, not pushed. This is a 4wd tractor
with larger diameter front wheels than 2wd.
I think it is the wrong shape for a set of discs which usually are at a 45
degree angle.
It is hydraulically raised and lowered, (must be, it is so close to the
drawbar)
so I think it is a set of rotating curved blades on a long shaft, powered
through a central gearbox. Sometimes called a "rotavator". The extra-
smooth result also leads to this suggestion, and it would be ideal for
throwing the soil back up-hill. One of the problems of ploughing up and down
on a slope like this is that of soil-creep whereby all the loosened soil creeps
downhill.
Discs leave a rougher surface. Tine harrows are significantly longer from front
to back and also would not leave a result that was altered so much.
So sez Brian, son of a one-time farmer.
