Being new to owning a compact tractor I've just realised there are different types of rear 3PT linkage. Can someone tell me what the difference is between cat 0, cat 1 & cat 2 linkages. I'm using a old Zen Hon ZL2201 (Kubota L245) within my small fencing & landscaping business with the intention of powering a post driver, auger & various other implements but need no find out which linkage my tractor uses. What are the differences ? Can I use cat 2 on say a cat1 or vice versa ? In the past the only tractors I've used were all full size agricultural tractors with implements to suit so I haven't had this problem. As I'm on the lookout for various second hand implements I want to be sure I'm getting the correct bits for my tractor. Any help appreciated.
