Well when we pick up our 121-3 kubota excavators from customers it takes us about half an hour to check the machine in. It's a 9500lbs machine btw. But when we get it in we wash it and make it shiny again (which most contractors don't do because it's not a big deal to them, but we have to please the customer with our nice looking equipment), clean out the tracks and if they're really caked that takes a while, then do the necessary check over...belts, radiator, hyd. oil, engine oil, air filter, lights and gauges work, no cracks in tracks or anywhere on the hoe etc. etc. Then you have the 200-hour service, which takes about an hour to an hour and a half. Then you have the 1000-hour service, which I'm not too sure how long it takes but I know it takes a while because that is where you empty EVERYTHING.
Everything else you can't really put a number or any kind of figure on it because everyone is different and there are different circumstances in everything. It takes me 5 minutes to chain a machine down, but it may take longer for someone else. Driving to and from jobsites is something you'll have to figure out. If you know your area well, you'll know what time of day traffic is the worst and what routes to take to go around it, what routes to take for unexpected motor vehicle accidents etc. How long it takes you to fix a broken hyd. thumb is something you know, we don’t know how fast and/or knowledgeable you are in this area. How long it takes the manufacturer to fix is dependant on many things.
We had the ROPS for a Kubota 121-3 bent and it took over a month to have it fixed. Because we had to wait for a brand new ROPS to be built in Japan and sent over. They don’t just have replacements sitting around. They come straight from the factory. So, there are a lot of things that can’t be pinned down because only you know your area well enough to base some common sense judgments.
