Loader is easy. Weights are better, but cost money and are a bit of a hassle. I find that when I mow with my loader on I have to be really careful - you are focused on the mower behind you and can accidentally swing your bucket into things. Anything your tractor touches is immediately broken, so I find myself fixing things around my house if I mow with the loader on. Of course, out in a field is quite different. Taking the bucket off helps, but the loader plate still sticks out a bit.Thanks. It does seem like I’m going to need to do something to keep weight on the front based on the comments here. Either the loader or weights?
Personally, I'd just mow with the loader on and see how you go. Easy to add weights later if you decide the loader's a problem.
