Just picked up a JD 290D excavator,, 6200hrs. Decent shape, not a busted up , has a mechanical thumb and 3 buckets with it. I am looking for pros and cons of the 290D, anything that I should be aware of as far as possible issues. I also have never even been in the seat of an excavator, I am a dozer operater, I am 64 and retired from a Logging and sawmill business, too old to chase women so I am starting up a small land clearing, food plot construction, excavation operation, I also have a D4C with a root rake. Thanks
