I can't say enough good things about a case 580. This past winter I had to rent one for the winter to load sand and salt with. We were so happy with the unit's performance for stack snow, we plan on renting 2 this winter. The rental rate for the unit that we recieved was fair.
We do, commercial, residential and private roads. I am located in Maine, what we consider big is probably small to you guys. I am not sure on the exact figure for the rental over the winter, however i belive it was between 800 and 1K. The 580 was our yard machine for the season, because my backhoes and loaders were out on the jobs.
Chuck The Case backhoes are as follows in the 580 line,C wich came 2wd only but you could get extendahoe,D,E,K ,Sk,L,SL all came with 4wd,extendahoe, and cabs as options all machines came 2wd standard hoe unless otherwise ordered with it.The G series was short lived and I can't tell to much about it but to saw I heard It was not that good of a machine.Case went thru many diferent machines from the K series on trying to make them better which leads to the series II's and so on.The 590 is probably the best overal machine for it size and wheight and digging depth and it's small foot print compared to some other brands out there and with the 590 your in the 100+HP range.
Be careful what you put on it to move the snow. My buddy works for a bigger company in the area and they put him in a case backhoe 4x4 I'm not sure the exact size it was but it had a 14' protech on it and he said when the snow got heavy and wet and especialy if there was any ice the machine wouldn't push it at all. It just sat there with the tires spinning. He spent a handfull of long nights this past winter clearing lots with just the bucket because the plow didn't fit the machine.
That is why, I may sound Old School. However on our back hoes, we have 10' blades. On our loaders with pushers we run 16 pushers and have 14' blades if needed. During the day, when you are plowing around cars we just run the blade, scrapes better.
I agree with geoff You would be better off with a 10' blade if you had to have it than a pusher box.I use my 580L more just for pileing than pushing.Unless it's very heavy than I just scape with the bucket a little more time consumption but it gets the job done in the end.
