Snowblower model???

Recommended Posts

ML3

Trying to figure out what model snowblower that came with the 702. Model/serial # no longer attached. Need a belt & trying to figure out what size. The original Wheel Horse belt is so brittle it cracks/breaks when I bend it so its bout impossible to try & match it up at the farm store. I think the # on belt is 1588??

For all intents and purposes it is a STR 324.  I am not sure the pulley/fanbelt set-up for turning the shoot is factory...but that is a nice set-up.  :occasion-xmas:

I scored the same model Snowblower  that was a complete NOS barn find. Over 50 years old - never mounted to a tractor!! Mounted on my 854 with an 8 speed. Low range makes for running the engine at WOT with a crawling ground speed if needed...

I did two modifications immediately - these were WH improvements on the 1965 version.

I added a second upper chain idler and rerouted the path with a longer chain. Thir greatly improved the "wrap" on the auger sprocket. Yours only has 3 teeth of the sproket engaged with the chain - very prone to stripping teeth off the welded-on gear....

The two ball bearings for the driveshaft are not the spherical floating style as OE. I changed those to the floating style, as the sheet metal housing tends to bend and wiggle in use...

My 2 belts were brand new but dry rotted - TSC had what I needed......

Cut the belt, measure the length of it and go get one. It's easier than measuring a circle. :twocents-02cents:

Yeah factory, the early ones used a belt

The last thrower to use the belt to turn the chute was model ST-323.

It is also the first to have square ends on the housing. Before this they were round and 30" wide.

The 32 is the width and the 3 = 1963.
