63 simplicity 725

Recommended Posts

Hey all I have a 1963 model 725. Great little tractor. I plow snow in the winter with it and I use it to tow a water trailer in the summer. My trouble is that I need parts and do not know where to get them from. I need the rear wheel hub gear and it would be nice to replace the 4 planatarys also. I hope someone on the board can direct me! Thanks a million!!! PS... I have two wheel hubs, both now with bad gears. One hub has roll pins securing the gear to the hub and the othere appears to be pressed onto the hub. Were there two different methods of securing the gear to the hub or did someone devise the "roll pin" method as a repair?

Welcome There were 2 designs of hubs early and late. Those were the two methods of securing the gear to the hub. 1st option is to download a parts manual and get part #'s most parts are still available from dealers. 700/725 operators and parts manual. http://www.simplicitytechpubs.com/6767PRINT/PDF_files/TP_100_1231_00_LL_S.pdf 2nd option is to place a want ad in the clubs classifieds section. 3rd option is to watch ebay for used parts

I have a 61 that I have installed the later model axle and differential into. The parts I used are from an AC716. The late model axle and diff is a direct replacement if you replace the diff, axle and hub. The left hub is welded to the axle on these. I think the gear is also furnace brazed to the hub on the right axle. There are no set screws, because the springs inside the diff provide the friction to control the traction.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
