Well, It took a while but the owner finally got back to me on the Dozer. The serial number is YCT0608120. He thinks it's a 2005 or 6. He's the second owner. He purchased it 3 years ago with 30 hours from the original owner whom purchased it from Northern Tool and now it has 60 hours on it. All the fluids were changed about 1 year ago. He's selling it because he doesn't use it. Supposedly it's in great shape and is always stored indoors. The price is now firm at $6,600.00. Gear Drive, No Problems. If everything is true, what do you guys think? Thanks, Frank
