Tesla and MF, thanks for your replies.
The soil is a clay loam over keuper marl base, which can be quite sticky. The Farm already owns some land adjoining the land to be rented, and this land is worked with the carrier. Ploughing hasn't been in regular operation for several years now, last year several fields were ploughed to get rid of some very strawy manure from the youngstock side of the dairy unit, however most manure is from the indoor robotic milker herd.
I can certainly see the merits of using contractors for everything. We had a consultant come to lecture us about farm business consultancy, and he said that it was important to consider other aspects as well as the financial, and one of these for my study is the fact that it is the university farm that appears to value their image.
It appears I have two options, one being a purely finacial recommendation of selling most kit and using contractors. I think most other farms around here seem to use contractors, ruling out joining up. My second option would be to use the existing equipment, maybe replacing the ropey set of 3m simba discs with a carrier or sumo trio, or possibley a Horsch FX or FG to get some fuel efficient cultivations going on, and maybe a Moore Unidrill.
We use a Moore at home on heavy soils and find it fantastic. Going with a Moore would mean that the horsepower available could be put to better use compared to other drills.
What are peoples views on drills? How good is a Horsch CO4 compared to the Pronto, Rapid, Unidrill or dare i say, a Claydon?
