1967 BROADMOOR 707

Recommended Posts

I have a 1967 BROADMOOR 707. Got it from my Dad. It has electric start, the 32" deck and the snowblower, along with some weights. I can't believe there is a web site devoted to these machines! Anyway...last week I replaced all the drive belts (1st time ever) and what a difference; can almost pop a wheelie! But now the next weakest link seems to be the engine (completely orig and untouched from '67). It dogs down and puffs alot of blue smoke when I'm mowing up a hill. I have to top off the oil every 10 hours or so...I guess I need a re-build. What are my options? Is there a rebuild kit or an OEM replacement engine? Has anyone done this rebuild? Thanks for any info. OBTW I have all the manuals and original Simplicity brochure from '67. If anyone needs some specific info; let me know. Later

Without knowing the specific # of your engine it is hard to answer your question. If I were you I would pull the motor and rebuild. You can get a set of rings and a gasket set for less than $50.00 total for a normal B&S engine. My son (3 years old) and I have had a lot of fun learning about rebuilding motors from the people on this site. I look at this as teaching my son not to be afraid to take on a project. One tip I can let you in on is just take your time when rebuilding. Many people get in a big hurry to get the motor back on the tractor and forget or don't do something they should have. I know this first hand from rebuilding a 6hp briggs on my 627 Yeoman. I wish I would have had the block bored when I was rebuilding. My son and I now have a tractor we have affectionately nicknamed "Smokey".

I have two 707's one is for has the original engine (briggs # 700701) and is used for parts while the second on has a replacement motor in it and works wonderful. If you want I will get you the replacement engine #'s. This are my 12 year old son's tractor for mowing 2 acres. he loves it and it does a fantastic job. I also have the snowthrower.

      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
