I have a cheap residential gravley zt2350 50" from 2006 and I use that on my small farm to cut tall grass, pond reeds where i won't get stuck, a lot of sticks to small parts of tree branches, and a good bit of rocks and the old cheap thing just keeps going and going. Many think you have to buy one of those 7k+ machines for what I put mine through but it's on the original engine and I've replaced the seals in the hydrostats only once recently. It's a simple thing just a hydraulic motor and pump many think they're hard to work on but they're not. I don't baby it i have it at full throttle all the time. I'd suggest buying a decent 3k zero turn and using it until it fails then buying another one.
Looking up basic 50" zero turn prices has me shocked they're almost double but that's par for the course in 2026. If I was buying a new one today it'd most likely be these.
