B series rotary broom hitching up to tractor?

Recommended Posts

mwells
Does anyone have any manuels, pictures, liturature, ect on how the rotary broom mounts up to a B-12 or B-112? I have looked at pictures and called sweepster, but they don't have any infromation on the B-series hitch. Any help would be greatly appreciated! Thanks

Well the guy at sweepster said some use a belt system and others use a belt and gearbox system, I know that the 700 and 900 series used a gear box and belt system, and the 300 and 400 series used only a belt. As for the B-series I'm not sure. I would like to keep it original, as the b-series sweepster had a metal cover, and the 300/400/700/900 series had a fiber glass cover. I have a 300/400 series hitch, but that was for the electric clutch type mowers, and I'm assumming that it would work on the 700/900 series as well with the cone clutch. It has a spring on it to keep the belt tight at all times, unlike the b-series that in the litureature it looks like there was a lever to engage and disengage the sweepster like a over center type system. There is a belt running off the engine pulley down under the frame, and it kind of looks like there might be a gearbox there as well, but I can't tell in the picture. Its mostly just side veiws of the tractor and sweepster, so there arn't any good pictures of the hitch/drive set up.

Like Maynard said, it appears to be a similar drive to the snowblower from what I could tell from blowing up the picture located here. http://www.simpletractors.com/attachments/rotary_broom.htm It appears to have the single belt clutch setup.

I have a friend that has one for the B series. I will have him send me a picture of the hitch and I will post it for you. His has the plastic cover as well so they must have changed to that at some point in time when they were building the B series tractors.

Rays, by chance you didn't see if the gear box is a ratio gear box did you? By that I mean, is 1 turn on the input shaft equal to 1 turn on the output. I'm also trying to set up a broom on my 3200 series, but the angle box on my sweepster is just that, no gear reduction. So if I run it direct from my front pto, I thnim the broom would be spinning too fast.

Mark I think that you will find that the ratio reduction is in the P.T.O. pulleys. The drive pulley is smaller than the driven pulley. IE. the pulley in the picture looks to be a 5" pulley which would be the correct reduction for a B series also your 3200 series with the standard 3½" engine mounted P.T.O. pulley.

Thanks for the picture! As for the gear box raito, its 3:1 for those that use the gearbox, at least thats what the books say, other wise its just reduced from different sized pulleys with the 100% belt driven hitches.

Thanks for the gear ratio. I have one that does not have a ratio in the angle box, it originally was set up for a Ford tractor with a 540 pto. If I were to run it as is, my brushes would be spinning 3 times faster than what they are designed for. That could get imteresting.

      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 
      Paul
