There are a lot of these problems with Farm Pro. We have a 2420. One thing you can do in daytime hours is jump the starter. It will run. Put 2 scruedrivers one on the bat side and the other on the starter wires side & touch them together. Make sure the clutch is in pushing down that pin.
It will run until you solve the problem.
