Talk to me about the Case 1845C. I have an early unit- split lap bar, and I have put about 400hrs. on it. When I bought it, it was pretty clean, and did everything it was supposed to. Actually, it still does. However, when I bought it, it was only showing 88 hrs. on the clock (obviously incorrect). I've read many threads about how bad it can be when a drive motor goes (replace both, and the tandem pump) and that has me nervous. If something like this happens, it really doesn't make sense to put $6000 into an $8000 machine. In your estimate, is it time to upgrade, or would you keep running it? It does need tires, and and drive speed on the left adjusted (creeps forward). Other than that, I have replaced the sprockets and chain on one side, fixed lights, and fuel gauge. I use it to plow snow, grade stone, lift with forks, and load my single axle. Keep or upgrade?
