I dreamed of owning a backhoe since I was a kid. I bought one to be used mainly for hobby purposes and snow removal during the winter. It's a 580SE. I believe it's a 1984 but I've not verified it yet with the serial number. The previous owner was a long term family friend. He told me the engine was overhauled about 20 hours ago and a new transmission was placed in it. I am now attempting to learn how to repair and service it. I apologize in advance if I'm posting this in the wrong place and I'd welcome any suggestions for forums that may be more appropriate. The engine starts and runs strong. The cab is not enclosed and I can see a broken weld on the muffler. I will work to get this replaced as the smell is strong when I'm running it. It does have some fluid leaks that I will need to get corrected. I'll be asking for advice in the future. I did purchase a repair manual so that may help with some repairs. Another priority is getting the brakes to work. I have almost no brakes so I'll be taking a look at the braking system. I welcome any suggestions or input. I'm going to do a full filter replacement as I don't know how long they have been in place. I will also change the oil. Any suggestions on using RotellaT 15/40 oil? Also, it leaks hydraulic fluid. My local NAPA suggested their AW46 for my backhoe. It appears it's made by Martin Lubricants. Is this compatible with the suggested fluid made by Case? Thanks for your help and any input you may have. You'll find that I'm a pretty decent guy that will likely have a lot of questions. I also have a Ford 8N tractor that has been sitting for many years. I'll deal with that after I've gotten some of the backhoe issues corrected.
