450C is a powerful machine for it's size. But, no . . it does not have hydrostatic anything. Has two transmissions; one is gear-driven range transmission with four speeds; and the other is hydraulic with clutch packs with high, low, and reverse - thusly known as an HL-R. So, you have high, low, or reverse in your choice of four ranges. Steering clutches are also clutch driven, wet, and activated by hydraulic pressure. None of the hydraulic clutches either in the trans. or steering are supposed to slip at all under any conditions. There is a dry engine clutch that isn't used much and can slip. Sounds like the machine has some serious problems and I can't tell from here if the trans. is slipping, or the steering clutches, or both. There is a common situation in that particular machine that can make everything slip because of low-pressure. There is an adusting rod that has a relationship with the mechanical dry engine clutch linkage and the transmission hydraulic control vavle. There's a 5/16" (or maybe 3/8") aduster nut on it that tends to come loose, and when it does, the pressure runs too low. If the machine has been run a long time like this it's probably got some damage. I wouldn't pay $6000 for it, but that's me. If it was a dozer with a 6-way blade, I'd consider it. From what you describe, the winch is next to worthless, track-frames are welded to the crossbar support,radiator shot, needs new bottom rollers, needs radiator, and perhaps a transmission job and steering clutches? If you had the work done the repair bill would be more then the asking price. Now . . if you want to use it "as is" and maybe get something done with it - in my mind you're back to a $3500 machine (at best). In fact, it might be worth more in parts than it is to fix.
