AS AYF has pointed out a good used Kuhn Primor would do you rght, trouble is finding a good used one, by the time they come to be replaced they will have given their best, usually the beds give up, the rest is fairLy bullet proof,
Our was a 3 point links originally but we got an axle n draw bar welded on so we could use big squares n it's been no bother,
Do t bother getting a Primor with the chopper option all the combine knife blades will do is piss you off when it blocks up in the dark one wet morning,,,
64 ponies at the PTO should drive it ok, as you will know when it's thinking about dying as the engine will let you know,,
Would an old Teague tomahawk not do the tpjob if your just using rounds???
