Like the others say, takes a little practice ESP with a rear mount cultivator. Got to learn whee you are at, and look forward, keep your head in the same spot.
Hillsides are a little special, if you have any, need to again learn to put the tractor up the hill a little, as the cultivator will sag sideways a little.
And, if you make any curves planting, well hope you have better luck than me following a curve with a rear mount cultivator.....
If farming were easy, everyone would be doing it right? :)
