Having owned (and loved) a CK20
TLB and always having a lust for a BX
TLB too, I'd say that everyone is right. The CK is a bigger tractor and specs higher as a CUT but the BX
TLB as a SCUT is just as wonderful a machine. Smaller TLBs (both fit in this category) are really extremely useful tools. True the CK will lift, push and drag more but at the same time the BX will get into places where the CK will seem too big. I'd rate the CK as worth about six men with shovels and the BX maybe four men but they both get the job done better than dismounting and picking up one of those horrible shovel tools.
Having moved up to a 40hp
TLB with nine foot BH I can tell you that there are some jobs that I just cannot do nearly as well as if I had one of the smaller TLBs. I spent about two hours a few weeks ago trying to delicately redig a garden next to our house. Would have been much easier with either the BX or CK20 and I would have done much less damage to the lawn.
Be happy with whichever of these two machines you have.
