That's a solid core baler. They were the first to have the TDC air over hydraulic belt tensioning instead of springs. The only thing in the world that I'd be afraid of in those anymore is that they used a big table belt in the bottom for the bale to roll on instead of a roller. You'd have to go to a 1460 or 1860 to get one with a roller. If the lacing pulled out of that belt,you'd have to find some place that could put a Dutchman's splice in it. Other than that,they were a pretty simple,reliable baler that made a nice tight bale. I've been running Gehls since 1979. Just like any round baler,there's a little bit of a learning curve to learn to start a bale,but once you get it,you're good.
I remember a salesman telling me one time about the first one he sold new,a Gehl 1450,he went out to show the buyer how to run it,but he said he didn't have any more clue than the guy who bought it. He said they had a few premature births and some aborted babies,but they finally got the hang of it.
