Interesting you say that. I'm in Long Island. The seller I got them from got them at an auction. These were made in Canada, and the guy I bought them from had called the Boston Lawnmower Company to figure out what they fit and the rep said that these were manufactured for several utility companies that had these Ariens snowblowers on site at properties that they maintained. So they got stuck with a bunch of these as the snowblowers aged out. The Boston Lawnmower company actually looked into retrofitting these onto newer machines but nothing came of that. At this point they don't have the technical drawings or any parts, but they do have 6 in their warehouse still.Nice... I remember about 10 years ago some guy in Maine was selling a bunch of these for super cheap but it was local PU way out in Maine east of Jonesboro?? almost to Canada. These were Canadian made.
I'm pretty sure that it would fit any of the large wheeled ST line blowers. I bought them for 100 each. I went there to buy one and saw he had 2 so I got both. I just bought a new old stock air filter setup with the carb cover too on ebay so that I can run a filter. I had to try it out but will definitely be using a filter.I would be taking off the heater box, and putting on an air filter for running in summer mowing setup.
Curious, what did you pay for it? I have a 724 ... interesting .....
The height is controlled by this lever, and the u joints allow the deck to raise and lower. The speed is controlled by the pulley and only adjustable by the engine rpm, I assume the same as the ariens deck.OK so there is no spindle per se, the blade attaches directly to the angle gear without any blade brake and speed is determined on by the pulley sizes off the engine/Implement PTO?
Please show more of the height adjustment and front casters.
It seems very basic compared to the original version which was set up to roll left or right (with the turf) at the tractor PTO axis, then used an angle gear in close, then via vertical belt to a sliding pulley on a splined spindle shaft, which stayed in the stationary plane when the deck was raised or lowered. This also allowed safety clutching on both the Dog (which was also clutched by the tractor clutch, and via deck idler to engage blade rotation (so four clutches in total, Tractor, Dog, Blade, and Diskomatic, 5 if you engaged/disengaged the drive wheel locker)
Yeah looks like a 1" shaft. The pulley on the mower is much smaller than the blower pulley so it does require its own belt, which the kit comes with.Ok I see they use a band brake and what is that a 1" shaft? Can you use the same belt as the SB attachment or does it take a dedicated one? I like the simplistic caster fork. I do not believe there is a brake on the original Ariens 26". I'd say you got a heck of a deal for 100 because of that gear box alone.
OK then the next thing you should figure out is the blade speed reduction. To do that you'd have to spin the blade by hand one full revolution while you or a helper estimates the number of times the driveshaft rotates. It could be 1:1 or 2:1 because we know they changed the pulley to get the desired speed. (changing the pulley size is a cheaper route than a fractional gear), but it could still be fractional and if that's the case just estimate. Then you'd have to measure the engine sheave and brake pulley and calculate the primary reduction (it's usually 3:1 or so for the SB pulley or 1000-1200 rpms). Then you multiply the PTO primary reduction by the angle gear reduction then divide that into your rated governed engine crank speed and that would give you your blade rotation speed.Yeah looks like a 1" shaft.

It's really just simple arithmetic. Most likely the angle gear is 1:1. and it's most likey the pulley choice is a compromise for all purpose mowing and general conditions suited to an 8hp Tec engine. It' s handy to know cutting tip speed.that sounds like a like of work! haha
