John Deere MX7 Rotary Cutter Gears or Replacement Parts
Hi,
Does anyone know where to get the gears for a John Deere MX7 Rotary Cutter? I sheared the output gear. I would prefer new, but would take a salvage part. Two independently owned dealerships says the part has been discontinued, and that I must spend ~$1,600 to upgrade the entire gear box and stump jumper to the HX7 setup. Is this possible to repair the old gear? Is their an exact replacement in a different brand? I have also heard that gears are always replaced in pairs. Is this true and why?
Thank you for your help,
Jesse
Re: John Deere MX7 Rotary Cutter Gears or Replacement Parts
Dealers could be correct about gear sets no longer available. I think the gear boxes were made in Spain and now are made in China. There was an earlier thread you might want to seach for about using a Bush Hog gear box sourced from Surplus Center on a JD MX6 cutter that blew the gear box.
I too have heard certain gears must be replaced as sets. Axle ring and pinions come to mind. The why? I think they are machined or lapped or run as set before hardening, but not sure.

Have a low use MX6 and gear box looks good less the out put shaft made of a low grade metal
I purchased a replacement Bush hog cheaper than the MX6 gearbox parts.
