Help with evaluating/buyer older excavator

I am clearing my own land in East TN and own and run a Bobcat E42 mini ex, ASV 135 (moved up from and ASV 75 in 2023) with mulcher, and recently bought a 1972 Cat D8H. I wouldn't have bought the Cat without having a great neighbor who not only has run them but worked on them. We replaced the rails and sprockets, refurb turbo and all new fluids and filters. Runs fine and great for building roads. My neighbor does the big work but he is teaching me how to run it.

Anyway I wanted a larger mini ex, but during Covid the E42 (5 tons) was all I could get fast. It has been a good machine for it's size, but I am asking it to do too much. The land I am clearing is mixed hardwoods from saplings to 24". I mulch trees up to 5", save 5-8" for firewood, send 8-11 to the pallet mill and the 11"+ to the Amish mill. Digging roots out on a 20" scarlet oak and then moving those logs uphill is more than the E42 was built for. The D8 is great for knocking down trees, but there are places best done with an excavator, and I don't want to move downed trees out with a winch.

I was thinking about trading in the Bobcat on a larger mini ex like the Bobcat E85 or Kubota KX80. Both of these are around 9 tons. I haven't priced the Kubota yet, but the Bobcat sticker is 140k which sounds way too high. I paid 61k for the E42 in 2021 during the height of Covid.

All that is background to my other option - buying an old mid size (15-20 tons) machine. When I say old, I would prefer pre def, and expect that it would have 5-8000 hours on it. Much like the Cat D8, I am ok with investing in some parts and doing some work on it, but I want to avoid big jobs like cylinder reboring, or replacing all the seals and bushings.

I check the auction sites and these things seem to trade at a reasonable value to me. But I don't have a handle on how much repair/update work is usual for, as an example a 15-20 year old 15 ton excavator with 8000 hours. I realize this question is machine specific, but can anyone offer general guidance?

If I pay 30k for the example above, and budget 20k in parts and labor (mine and my neighbors who is very reasonable), will that get me a machine that is reliable for personal use of around 500 hours per year mostly clearing trees and digging ponds? All all cylinders and hoses pretty much shot at 8000 hours? I am comfortable evaluating the undercarraige and updating that if needed, but have no experience on other systems of big excavators.

I am not hung up on brands, but appreciate any thoughts on this forum of the brands that are built well and last, and what to expect if I go down this road.

The 90s Japanese machines most had Cummins minimal electronics be aware of grey market ie purple and gray Komatsu or Cat that are actually Mitsubishi machines parts are hens teeth. 180/160 class counties pulled behind their dump trucks times see a good ex gov machine most of the time waiting for the spring Creek clean out

I have been looking over a few excavators on Facebook and cl, there is a nice selection of bigger machines 15 to 30 ton on Facebook in the south. Looks like a construction slow down is on the way. I was window shopping only.

Rental fleets have been getting the snot worked out of them over the last few years so they are constantly getting new equipment. The older pre def machines are needing more maintenance, hoses and hards parts are getting more worn as they age so a lot of those are being upgraded, to newer machines.

Timing is looking about right to find a deal.


Here is an example


I don't see how the dump moves a 322 but what do I know?

100% the 15-20t option, you won’t get far digging ponds with an 8t. What is your budget? That’s the key thing we need to know.
Budget is 60k all in. Thinking 40k machine, 20 Parts and labor. That is machine, parts and labor to get it to a reasonable condition to work 5-600 hours for 4-5 years removing trees and digging ponds and roads.

Great advice. Since I hope to run it at least 5 years parts availability is an issues. Thanks

From what I see on Youtube there are free for the taking old excavators and dozers buried in the woods everywhere.

Most of them start right up with a battery and some new fuel.

Not so ?

Those field and barn finds are little too much for me. Yes HeavyDSparks seems to get anything running, but to get one of those in the condition i want would take too much parts and labor. External engine work doesn't bother me - turbo, fuel pump, hydraulic hoses. What worries me is big cylinder work like reboring.

That dump truck has a Chilton County Alabama tag on it. Interesting that it's for sale in Macon.

Buyer beware with that lot.

300 Komatsu Excavator engine runs. It works however when hot the rotation is weak and one track is weak. I’m 74 yr old and just don’t have the ambition to deal with it anymore. I am motivated to sell or consider a trade. Please read the Hydroforce Heavy Equipment letter describing the work done.

Seems a great many larger excavation companies around MO have stranded machines they do not want to invest the time or money into and offer them off at what they consider On the Cheap. Again Buyer beware as most need tons of work, parts are becoming scare on 15-20 year olds where many of these are closing in over 30. Then comes transport, when new were hauled in apart and assembled at site, these have to be removed same way, cranes, ground support crews, LOADS of heavy tooling and time paid for with real money.

However these old excavators give the youtubers hours of content... :rolleyes:

Will it crank??? So stupid and boring.
