So I did my 50 hour service today, and everything went well. Except for this:
Fortunately, I have a great dealer. Cazenovia Equipment in Oneonta, NY. I sent them those pictures and they are coming to get the tractor and bringing me an x570 or bigger to mow with in the mean time. They gave me zero grief about it, they are just going to take care of it.
These tractor dealers, they're pretty amazing. Some of them anyway. Glad mine is one of the good ones.
