I have used single stage snow blowers for years. Got this 2 stage to try out. Not familiar with them and am wondering about the play in the gear box. This has a shaft that goes through the blower and then into a box on the auger. Spins nice and quiet, with no vibration, but the shaft spins about 1/4 turn before activating the auger. I figured that out turning it over by hand. Haven't actually mounted it on a tractor yet. Am worried about having that much play causing damage when I kick on the pto. Any thoughts out there? Does the box need to be rebuilt?

Download the manual and see what the specs say.  That will be real nice when its working.

There isn't much that can be done without replacing parts inside the gearbox, so why not just use it until it dies?

 

Another source of play is enlarged holes in the shaft and/or auger where the shear bolts are located.

Would love to download a manual, but haven't been able to identify the brand. At first glance it looks like a Gravely, but is very different from the ones in the manuals section.  Paul

With the drive shaft, I thought Bolens or MTD.

Not a Bolens, but is going on one. Don't know anything about older MTD stuff. Didn't know they used shaft driven implements. Will look into that. Thanks, Paul.

  Could be excessive wear on the worm and/or ring gear or excessive end play in the worm shaft.

You might be right about it being MTD. Very close. The case on this is 37.5" wide. The MTD's I have seen, so far, are bigger or smaller. Did MTD make a 38" 2 stage? I found a single that size that looks like same manufacturer.

Thanks, Paul.
