This Traction Control was offered by Cat as an option on all 3-axle tractor-scrapers in the sixties : 630B , 650 , 660 , 666 . I had never heard about this system in 50 years , but I came across at a scale model of the 666 , bought by a relation of mine . He wondered the function of the 2 hydraulic cylinders on the floor of the tractor
( see pic) . When I browsed my files I read about this system , but I never saw one or heard of it during all the time . I am surprised by the scale model makers who are also not aware of the function of this system , and so do most model collectors as I noticed .
The system can put more weight on the tractor drive wheels , taking weight from the front axle or even lift it from the ground in order to improve traction . .
There are several model makers who equipped their 666 models with it , probably they recklesly imitated the machine out of the parts book . So , I think there are more scale models with traction control than real ones .
Are there any operators or others who have known this system , or is it a great mystery ? Let us know about your experience !!!
