Ariens ST 724 impeller does not move under stress?
Moved some heavy snow today and then the impeller stopped working. No objects in the way. Spins if I clear chute but boggs and does not have enough power to move snow out chute. Do I tighten belt? Does it have that capability or do I need to replace the belt. If so what is the belt #? Thanks for all your help.

Hi, I will try to help you with this problem. I think the problem might be an adjustment issue. If you take the cover, usually plastic, situated just in front of the engine housing, you will see the belts and pulleys. Without the engine running, press on the auger/impeller lever, and if you look inside you should see how the belt is made to engage the auger pulley. Probably by an idler pulley that pushes on the belt to make it tight to turn the big pulley. That is the most popular way, it is to loosen the bolt on the idler pulley and push it towards the belt so it applies more pressure to the belt to turn the auger pulley and tighten the bolt. There could also be an adjustment on the linkage that might be adjustable. Another possibility is that the belt is worn and is riding on the bottom of the pulleys therefore not providing enough friction to turn the pulleys properly. I think if you take a good look at that system you will comprehend it. Hope this is helpful. All the best and good luck. I will gladly answer any other questions.
Sounds like you have a broken or partially broken shear pin in the auger.Check along the auger[machine off]and see if there is what looks like a bolt anywhere along the auger shaft.If there is [and there will be] remove and inspect it and you will see why the auger is not working.Next time,never clean out a chute or auger while the engine is running,people loose limbs this way.
I would check your traction drive disc for wear or shredding.With low or little fuel in tank you can safely grab handle bars and lift machine up on it's auger housing.Then remove shield from under machine and inspect metal disc with rubber around it.If rubber looks worn you can get a replacement traction drive disc easily from most small engine repair shop's or go online and look for your nearest Ariens dealer.
Start buy checking the gear box to see if there is any cracks in the housing if there is then your going to need a new gear box assembly, sometimeswhat will happen is the auger will stop do to an object and the shear bolts don't break while the impeller is still triing to spin causeing the gears in the gear box to break.You can go to www.ariens.com, then go to parts,then click where it says click here to enter Parts Radar, you will need to have your model numberyou can get the break down for your machine which will help in dismantle and puting it back together you will also be able to get the part number for any parts you will need. If you need a new gear box get the whole assembly not the indivisual parts. any other questions please feel free to ask.
