I think cat made powershift and standard clutch models same time cause in our family company has -74 d4d and it has poweshift. 3 gears forward and 3 reverse and no clutch.
The drect drive means that it has a standard clutch. Not an automatic or power shift. This dozer has a hand clutch. It has 5 speeds foreward and reverse. I will make a descriptive video for you if you want.
Ah i see, it has nothing to do with the position of the drive sprocket, but about if a torque converter is fitted or not.
Up to which machine size did they sell them with direct drive ?
Yeah a descriptive video, i'd love to see that ! In Holland you hardly see any bulldozers, most of those jobs are done with wheel loaders or tractor drawn graders.
The term Direct Drive really only came about after the Power Shift Torque converter models were introduced.
A Direct Drive is just a "normal" style drive train with a clutch lever and a gear stick, like a car.
Direct drive's were made from the beginning, and all models came in them from D2 to D9.
In the late sixties, power shift came in. That means a torque converter and a gear stick that can be quickly shifted from forward to reverse while moving. ( it's easy ) No clutch.

Why do you mention its direct drive ? Did Cat sell high drive and direct drive at the same time, or can you read the age from the drive style ?
