Warm it up and make sure the drain plugs for the clutch compartments are removed to allow any melted water to drain. The plugs are there to prevent water from getting in when used in muddy/high water conditions. Also for washing out housings with diesel. Snow melt and rainwater drain into the compartments and freeze making it impossible to move components. A few years ago, my friend and I were going to pull start my D4 (gas tank was being sealed) and he pulled with his D4. When I engaged the clutch, my tractor became a boat anchor. Clutch compartments were frozen. In the spring, I pulled the plugs and drained alot of condensate from them.
5-8 minutes of warm-up time in 20 degree weather isn't quite enough. I've run D6C in the winter here in Upper Michigan quite a bit, and the transmissions can be sluggish until they warm up. We generally let them warm up at 1/4 throttle for at least 20 minutes before moving. Also when you first get ready to move the tractor, lift your blade all the way up, then all the way down breaking the tracks loose from the ground. This not only loosens the tractor from the ground, but mixes the cold hydraulic oil in the cylinders with the warmer oil from the tank.
Happy Pushing!!!! D6's are great old machines!!!!

Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
