Howdy all.
I wonder if I could impose upon your knowledge and experience to help out a newbie.
I woudl liek to get a dozer to cut trails, push down 60-70 foot Popple trees, clear thick brush, dig two ponds and widen my access road. Last time I hired a contractor with a Cat to do similar work I got charged A LOT of money. This time I thought I'd buy a used unit and do it myself (told the wife I'd sell it later, but we'll see about that...)
I came across a 1980 D4D that seems almost perfect for my needs. It is direct electric start, and fires right up with the tiniest puff of black smoke that goes away within a second or two. The guy who has it claims it was owned by the DNR for years who had it set up for fighting forest fires - so most of the time it did little work. It has a "third valve" he said was for the DNR's plow. He also claims the DNR sold it to a small town who owned it for 1 year, built 1 mile of road, and then sold it to him for a much bigger, much newer machine to buidl the next 17 miles. He says it has been serviced by a Cat dealership all its life. This guy seems to make a side business of buying and selling used dozers/excavators, usually much bigger than this one.
I know next to nothing about dozers. I do know they're really expensive to fix. I also know that for the money I've got (or rather, will have) that to expect perfection is unrealistic. This dozer has a simple up/down blade, lots of overhead protection, and the motor seems strong. There don't seem to be any hydraulic leaks. Apparently just before he got it it had $1700 worth of work for a new starter motor and associated stuff. The owner was quite upfront that the tracks probably should be replaced, but seemed to think that for the "casual" work I was going to do it'd be just fine for years.
Do any of you guys have any suggestions on things to look for/be careful of? Your time would be much appreciated. Aksing price is $9500
