This dozer topic is of high interest.
About 2 weeks ago, looked seriously at a '72 Cat D5 with a 4-way blade, about 65% under carriage - $10k asking price. It's still available...
The older D5s are smaller than new models, this one is 27,000 pounds and it's more like a current D4 or JD450 in size.
It's 50 years old, but still runs well and is reliable per the owner (a local guy, who grew up in this town and is reputable). He used it in his small top soil business which was shut down by the state due to their environmental over-reach (his words), so he's selling out.
My primary objective for it is digging a ~2 acre pond. Never built one, nor even operated a dozer. But always wanted to and thinking about giving it a go!
Trying to convince myself that owning a dozer makes economic sense...I can talk myself into it pretty easy...
My thinking is that if I buy it right > I can use it > then sell it at my buy price, so it should be only my time at risk if it doesn't turn out as planned.
My primary concern is I'm handy - but NOT a heavy equipment mechanic.
Unknowns are cost of operation and on-going maintenance for a dozer.
If it's reasonably sound to start...is it still a high risk of being a money pit?
Are dozers typically high cost to operate and high maintenance?
(Apologies up front for the interrupt, but this thread has a small group of contributors who I trust in their knowledge...)
