The FM180 is an excellent finishing mower that makes quick work of my property. The 72-inch cutting width saves me time while leaving the fields with a manicured look. Hookup to my tractor is simple, and it runs smooth with no vibration. A reliable and efficient piece of equipment.

I haven't had a chance to use the mower on my tool cat due to issues with the rear PTO. I had it put on my JD 3046 tractor. I did have to purchase a 3 point quick hitch adapter to get this hooked up properly and put in spacers to keep it tight. It works great. I adjusted the height 3 times until I have it mowing close to 3.5'' and now dropped it to about 3.25''. It mows fairly evenly considering I do not have even terrain to mow. I just got mt tool cat back and want it on that unit. I think the spacers will need to removed as well as the quick hitch adapter. However, not sure. Worth the investment!
