JD 420 60 deck gearbox

The gearbox on my Dad"s JD 420 60" deck went south last evening. Does anyone have any idea where (other than JD--new one"s $1,000 bucks) where a guy could get one new or rebuilt, or have any idea what it costs to rebuild? Any thoughts are appriciated!
Thanks!

Find out who made the gear box, a lot of them are made by Peerless and are lot cheaper than through Deere
 
You might figure out the ratio, and shaft sizes, then take a look at SurplusCenter.com. They have LOTS of 90-degree gearboxes, and you MAY be able to match something up.

When the gearbox on the 60" deck on my 400 crapped out, I did just that, and never did find one close enough, and paid Mother DEERE'S price, about$650.00, back a few years ago.

I hope YOUR luck is better!

(You might also try watching ebay. There's a couple of "regulars" there, who part out these tractors, from time to time.)

What "got" mine... I bought it used, but "as-is" from a Malice Chambers dealer, and was told they had checked all the fluid levels. The gearbox failed after very little use, and was "bone-dry" inside, with no oily mess in the lawn waste packed around it.

I DO try to remember to check the oil in the replacement gearbox, from time to time!
 
Most all the parts for all three choices of boxes used on the 420 are avail. unless the case and shafts are trash, bearings & seals can be gotten most anywhere for less than deere prices, even if you had to buy gears from Deere. Are there any Id numbers or casting numbers on the box? I have a couple that I'm not sure of the application for
 
Does yours have the spindle in it?? or does it have just a pulley on the bottom. I have a couple used gear boxes. 325 642 7647
