I looked at what was available locally for a couple of months, and what I found just didn't cut it. The hoses had rotted from the sun, there was significant damage to some areas, they were way, way overpriced; at least in my opinion. So, I bit the bullet and expanded my search online to nationwide. There were a lot of them out there, but buying something this expensive sight unseen was scary. Sure, people do it every day at online auctions and such, but they know what they're doing, ... I don't. So, I went on eBay and looked at their guarantee for construction equipment. They insure the purchase up to $100,000, and that gave me enough courage to contact a seller. The rest was easy. The excavator arrived in Port of Long Beach, CA; was inspected; loaded on a truck, and showed up at my house in just a few days total time. I was lucky in that respect, but I did choose a machine that was available instead of looking for exactly the right thing.
If you want to know the specs, the model number is right on the side and google can pop up a spec sheet in one search. What I like most about it is there ARE NO ELECTRONICS; it's old school hydraulics with valves and such. It can be worked on without a laptop plugged into a data port. Less failures to some component getting wet and less expensive control components. I can fix it if I need to. (or should I say 'when').
Now the bad stuff: When I got on it, having exactly zero experience on an excavator, I couldn't get it to go. Meaning, how the heck do you run this thing? I fiddled around and found the two forward controls for the tracks and managed to move it down the drive a ways. Then I looked at the control layout decal and managed to work it a bit. I got it from the road to my house in a few minutes and then started to play with it where no one could see me make a fool of myself.
After an hour of trying levers, looking at the instructions (shudder) and messing around I managed to make it do things. Then, I went nuts. Spinning around using zero turn, swiveling it around and around, banging the bucket on the ground. Basically playing with my new toy. It is so exciting to pick up a bucket of dirt, swivel around and dump it behind you. That is probably the most exciting thing about an excavator I've tried yet. It can really dig!! I can make a hole in no time, even with the incredibly rocky ground I live on. Just wiggle the bucket back and forth a little and it will bite in. Really large rocks give it trouble, and I have to plan better to roll them out of the hole, but so far, I haven't hit one that I can't move. I know I will at some point (it is a mini machine), but then I'll just go around the rock if necessary. And, it has a THUMB. In case you don't know what that is, here's a picture of mine.
This allows me to pick up rocks, grab a bunch of pruning, pick up a limb to chainsaw, etc. It gives me a hand to manipulate things with. This increases the versatility of the machine to a level that we, as homeowners, can really appreciate. There is one annoying thing about it though. The left hand control is set up counter-intuitively. Left hand left is stick away and left hand right is stick close. Left hand forward is swing right and left hand back is swing left. There are two control standards in the US, ISO and SAE; they differ in the positions of the controls, however both of them have the swivel control on the left hand side to side. That is driving me nuts. I keep swinging the excavator when I try to move the stick. It just makes sense to my brain that swivel left should be push left, not pull back. Yes, it can be changed by moving the hydraulic lines. However, the lines are plumbed, not hoses. Take a look:
Those two pipes are the stick controls, and I didn't want to spend a week creating new ones to fit the application. Note that steel plumbing is a good thing, it protects the hydraulics and makes for a really good connection, They are just really hard to move around. I may come back to this after a while and change it, but reprogramming my brain is easier at this point and it keeps the machine on the dirt doing what I need instead of sitting in the garage waiting for parts.
What's also awesome about this machine is how well it is set up. I can get to the controls really easily, the gas gauge is a clear tube instead of a float in the tank that fails, the horn is not where you'll hit it every time you use the machine. It even has a light that I plan on using very, very little. For example, the horn used to be on the right hand control where you manipulate the bucket and bang your knee. It's now on the right hand side where the other electrical controls are:
I may grind that mount off at some point, but want to have a can of Komatsu blue paint on hand when I do to keep it pretty. Wanna see the extremely high tech fuel gauge? I guarantee this will not fail due to a rat eating the wiring or some connection coming loose.
