mower on AC312H

Recommended Posts

I don't recall there being different blade sizes but someone may have substituted aftermarket ones which may be OK if thet still overlap about 1/2" and come pretty close to the housing. How does it cut the way it is?
I beleive 300 series was unique to AC.

Can anyone help on the proper blades for my deck
It has a serial # of 04203049 and the tractor has a
serial # of 04801399. There are 2 blades the same with a # of 2734 on the blade and 1 blade of a different length with a # of 0775. I want to know if these are the right blades or not. Also is there a simplicity equivalant of my tractor. I can't find one in the cross ref or don't know how to use it properly. Thanks for the help. Great site, used it lots since I got my AC

Just looked up some part #s for 300 & 400 series mowers. All of these numbers are available at Simplicity dealers, however I don't have any idea how many other dealers stock them.
300 series mower;
42" blades 1607536 no Sim equiv.
48" blades 1607369 no Sim equiv.
42" arbor belt 1603077 use Sim 108209
48" arbor belt 1603075 this # good
42" PTO belt 1606190 use Sim 108209
48" PTO belt 1604406 this # good

400 series mower: Same as above except PTO belts
42" PTO belt 1607812 this # good
48" PTO belt 1607813 this # good
If you have a 300 or 400 series parts book they will show the first # which AC used. the #s I crossed are no longer good and cross to the numbers I showed. Hope this is of some help. Good luck, Al

      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
