7 to 8 years ago. At that time the machine had a little over 3100 hours. For the past years it was only used in the summer time periodically. It is still plumbed so you can add whatever you want. I did not need different buckets and stuck with one. That comes with the excavator and is still attached. It is your responsibility to inspect the Machine , It is located in Mariposa Ca. My number is 925 628 6464. This excavator is for sale in as is condition. After inspection if you want something done to the excavator mechanical or otherwise I can have it done at your expense , or maybe at shared expense depending on what it is. Every hundred hours I would change the oil. Replace hydraulic filters , fuel filters , air filters. Replaced coolant once a year. Check and maintained final drives. Undercarriage Look for your self. Very good to excellent for its age. No monster hydraulic leaks. Last Maintenance was about 20 run hours ago. Here is what we did. Emptied all fuel and cleaned out the fuel tank itself from the bottom. Cleaned out fuel separator and replaced all fuel filters. Drained the final drives and replaced the gear oil to the appropriate levels. Replaced started solenoid because it was starting to stick. Cleaned and replaced Air filters. Replaced hydraulic filters again. Both deep cell batteries replaced approx. It does have dents and dings typical for its age. I will consider barter for such things as old coins gold ect. The panel door in the back of the machine can use someone to straighten it out. Looks like a simple dent to take care of. The cab door is removed but I do have it. It was damaged by my partner crowding a tree. It buckled at one end so we took it off and straightened it out the best we could. It could go back on I just haven’t got around to it. I was going to take it to a body shop and have it done until I decided to sell it. Boom/Stick Option (HEX) 1. Max Reach Along Ground. Max Vertical Wall Digging Depth. Width to Outside of Tracks.
