Don't overlook the Case JX series. It is a good solid tractor made in Turkey and imported to the US by Case. It has engines ranging from 42-80
pto hp. The JX75 (60
pto hp) has a 12 speed transmission with mechanical shuttle shift and can be ordered with flexible end links. It has a non-turbo 220 cu. in. engine.
Would also look at the Kubota M6800 (62
pto hp).
