Mike, not sure if there's a JD model 440... There is a 420 (gas) and a 430 (diesel). Here's a 430 that was at PD 13. Not sure who it is that owns it. A guy named Jim Dimmerling who shows up at lots of Plow Days owns several JD tractors, including at least one 430. Hmmm, a 430 seems like major overkill for lawn sweeping duties.
