Briggs question/good tractor time!

Recommended Posts

A friend of mine's tractor is currently not running. When he hits the start button or key, the starter spins, but makes a grinding noise like the teeth aren't engaging. It's a Briggs I/C twin cylinder. Any ideas? I know nothing about these, but would like to help him out if I can. I haven't tried anything yet, so any advice would be appreciated. On the good side, I mowed his yard for him last night with my B-208. I went through some thick grass about 10-11" tall with no problems if I slowed down. 3 hours of tractor time with great weather while helping out a friend. Doesn't get much better..... Thanks in advance for any help.

Stop by a Briggs dealer for a new starter gear. should be less than 5 bucks. You don't even need to pull the starter to replace it. Just pull the blower housing and replace the starter gear.. Good luck..

I would like to add after the new gear is installed check to see how deep it is engaging the flywheel.Several of these motors I had to elongate the front mount bolt on the starter to obtain a deeper mesh of the two gears.If the gear is only making contact on the edges it will wear out prematurely.

I fixed one for my brother, if I rember right the gear rode on a spline with left handed acme type thread. when the starter turned it forced the gear upward to mesh with the flywheel. I too had problem with plastic gear to flywheel mesh/alignement.

      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
