Just got a '59 JD 440 track loader.Cute little toy--has a 3/4 yd bucket--might need to split her open though as something is wrong with the reverser I fear.The only way I get her to go forward is to put her in reverse and place the reverser in reverse---2 reverses make a forward action--go figure. I've been told not to continue doing that though as I might wipe out the spider gears in the reverser.
I always found a bunch of information here with my JD450. http://www.jdcrawlers.com/
