BROADMOOR 728

Recommended Posts

I bought a 728 owners manual/parts list off ebay.....interesting reading because I did not find the same book on the simplicity site. It leads you to believe the 728 had an early series #577(corrected # thanks Chris 727) , then a later series #765. The main difference seems to be the improved parking brake mechanism (& mounting). Does anyone know about what SN this changed over or did the serial numbers start fresh with the new 990765 part number? Were there any other differences? Does anyone own one of these late ones? Thanks

Here are the 728 Broadmoors, Model year, mfg number, HP, Briggs model number and Briggs type number. 1972 990765 728 - 8 HP 191700 0638-01 1972 990765 728 w/o Mower - 8 HP 19170 0638-01 1971 990577 728 - 8 H 191701 0630-01 1970 990577 728 - 8 HP 191701 0121-01 Serial number to build date are a guarded secret and you are better off looking for an engine seial number and then we can come up with reasonable build date.

My 728 sn 3286 with engine 191700 1140-01 date code 79082110, but is obviously to new to be original. I'd be curious to see close up pix of the improved brake setup. OO

I just parted out a 728 - model/serial 990765 002253. Looking at Jacks Small engine site, this has the later style park brake - with the black lever that cams over and jams the brake on - it's located on the left fender. However, Jack's says that a 990765 is a 738. I am assuming that the tractor I have is original, and that the dash and decals have not been swapped with a 728. Someone modified my tractor's brake though - they had the brake drum mounted onto what would have been the rear PTO shaft - the LH side of the input shaft instead of on the brake shaft. That means the brakes would only stop the tractor when the trans was in gear!!!






As you can see, pretty nasty old tractor. I am keeping anything that will work on my older 717 and Yeoman, and anything for my brother's 5010. I suppose anything else is up for sale. The frame was broken at both front spindles, and repaired VERY poorly - I will try to post pics of that in another post - you will laugh. Tim

990765 tractor was part of 990780/990443 tractor mower package and the operators/parts book is one of the same. In the parts book, they are part for part, expect in the electricial portion, where it appears that Briggs supplied the booster fan and pulley instead of Simplicity.

Thanks very much for the feed back. The manual I got is for the #780 combo with #765 tractor and #422 mower deck. Looks like the serial #'s do start over with the new model 728, since Timjr's 990765 sn is lower SN than mine.
