John Deere Snowblower - wheel won't spin

The snowblower was working fine, one morning, I made one pass with it, then on the second pass, the wheel that picks up the snow wouldn't spin. It has the pull bar up by the handle where you pull it back to engage the wheel. Any suggestions on how difficult it is to take apart, and what the problem may be? This is a John Deere TRS 21 Snow Blower

    Thank you for helping with this. My guess is that I have to take it apart in order to take the augur off to check the sheer pins - correct? Sorry, I'm not much of a mechanic, but I can take things apart and put them back together. By just looking at it, I don't see any pins. The center bar fits into each side, and I don't believe it can be removed without taking it apart. Are the pins inside the casing, and not visual? Again, thank you!

Yes 2 solutions. the sheer pins have got broken down on that auger that wont spin, they go through the middle bar. easy fix. about 2 dollar.

The other thing is. The drive belt located directly in the middle of the machine has a plastic cover over it has slipped off or is broken.

THis is a little more tricky as you split the machine taking off the collection cage usually to fix. I charge 89 dollars in my shop to do these.

Its not hard if you pay attention to where you need to take off the parts.

    NO the pins are on the auger they look like bolts, the sides of the casing have a bearing that the side of the auger shaft fits in to.

    There is also sheer pins in the strait part of the auger going back towards the motor. Its basically a T so look closely at the auger and have a freind help. If the strait part going back is spinning then the sheer pins in the "blades" area have broke. Look for the things that look like bolts going through the auger "middle of the blade"

    If the strait part isnt spinning that comes from the engine side. then its probably just a belt. You wont aloways notice broken sheer pins becasue sometimes one hald of it is still in the auger area. look at both sides and if one end is open that pin is broken. -Jeff

How do I fix my snowblower when the wheels won,t move ahead or back

Sounds like gear on axle shaft broke shear bolt or key. Take bottom plate off base of snowblower.It is ok to tip snowblown up on front end so wheels are in air. After plate is off turn wheels and see if drive gear is moving with axle. If not key way or bolt has broken off, replace and will be back in motion.

John Deere Snowblower 1032 won't start. Obvious solution?

First dump the old gas and put in fresh. Clean or replace spark plug.
Put a squirt of starting fluid in the carb. If it fires the ignition system is good. Do this a few times because there is still old gas in the float bowl and fuel line. When the fresh gas gets to the carb it will stay running. If it did not fire with starting fluid the points and condensor will need to be replaced and maybe the coil.

Is there a GENERIC Snow thrower for John Deere 110?

Two Stage - Snowblower - Snow thrower - Bercomac All of the Bercomac attachments are interchangeable on the same quick hitch mounting. Bolts on in minutes. What a great idea for people who have more than one tractor or buy a new one. No more having to go and buy all new attachments for the new small tractor, just buy a different model hitch kit if it doesn't use the same one. The resale value is preserved when you can sell your attachments to be used on another size or model lawn and garden tractor.
