Difference between JCB Contractor & Sitemaster

[hakolos]

Hi everybody,

Would appreciate very much if you can enlighten me about the technical differences between JCB 3CX contractor and sitemaster. The same question applies for CAT 428 and CAT 432, 442 ?

Thank you in advance,

Hakolos

Hello. Don`t know much about jcb but i think contractor has 20inch wheels vs 18inch and contractor may have more hydraulic flow. cat 428 has mechanical controls as has cat 438, cat 432 has servo controls and more oil flow. Cat 442 has bigger a backactor, servo controls and is available with 4 wheel steering
