Family has arable fields on light chalky/flinty land (South Downs) which have been ploughed / power-harrowed /drilled / rolled for years (dont ask me why) and are very uneven and not level when going over the tramlines as seen in my very accurate diagram below. Is painful driving accross them at any sort of speed. Looking to level the fields probably over a couple of years with a min-till approch ready for a more direct drilling/no tillage approach what would peoples suggestions be? Also cant work out why they are so uneven, is it the powerharrow just making the ground unessecarily fluffy before 240hp heavy ish tractor with rolls comes along? As even new grass ley fields with same approach seem just as un level. Thanks
