I bought a 175 C dozer. This was a step-up from my Ford farm tractors. Of course, the item was used and without manuals. On top of that we live on a small country road and Rob, the trucker, was not going to be able to swing his 55 foot trailer into our drive. So, we unloaded it on the road and then had to chain lift a 2000lb Woodsman brush attachment and get it up a muddy, wet drive onto the farm. Sounds easy if you know how to drive one of these thing -- not so easy when all the controls are new to you, there isn't a manual, the seller isn't available by phone, reverse seems to stick sometimes, and you don't want to wreck the dozer, the trailer or the truck. We did it, Rob was patient and helpful and all went well.
Thanks Rob and Bill!
