My uncle bought a new 303 in 1965. It went through a D14, D15, 175 and a Deutz Allis 6260, and still baling. When he died in 2013, my cousin finally retired it.
A very much better baler than anybody gave credit for, not very common in the uk,but they did have the Jones factory tor a while. The only broken down one I ever saw was due to wheel bearing lacked grease ,heated and broke off the stub axel, it had been assembled dry from new. It had already done 4 seasons on hay and straw. Good machines
