Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi, I have a 3 year old Toro 1028 Power Max snowblower and after completing this years maintenance I noticed that it was creeping backwards while idle.

If I put it an any forward gear or reverse gear and move (either forward or backwards) once I take my hand off the throttle control the snowblower creeps ever so slowly backwards. Doesn't matter if I've got it in a forward or backward gear. I'm on level ground and I even turned the machine around to see if it was something as silly as gravity. Nope - always goes in reverse.

I've got the full shop manual and I've already adjusted the traction cable to spec and even tried adjusting in radically in and out - no difference at all. Still creeps.

Has anyone seen this before? Do you have any suggestions? And why does it always creep backwards even if it's in a forward gear?

Yeah mine goes backwards with a certain degree of force, but if the plates aren't engaging how the hell can it happen? I might tip it on the bucket with the bottom plates off and actually see if I can see what's happening.

It sounds like the drive and friction disks are out of adjustment.  The minimum required clearance to obtain and maintain neutral with no pressure on the drive lever isn't sufficient.  While idling, the drive wheel is making slight  contact on the reverse side of the drive disk.  You can try to loosen off the drive lever cable to give a bit of slack.  If that doesn't do it, you'll have to go inside to make adjustments.  Your manual should provide you with the proper clearance specifications to make the correct adjustments.  Saying that nothing can be done about this problem is. well, incorrect.  It can be done and for safety reasons, it should be.  

Borat, what you say makes sense - but it isn't the case. The gap is well within spec and I've checked the actual clearances myself and their fine. Also, it goes in reverse at idle while it's in any gear, I could have it in top gear and it sill goes reverse - there's no way there could be contact on the reverse section of the wheel. So it still doesn't explain it.

If, as you say ,  the machine will actually creep up an incline in reverse, that tells me that there must be power getting to the wheels to in order for it to do so.  Maybe you can tell us how the power is getting to the wheels if it's not via the drive system?  Not to challenge you, but it would appear that something is out of adjustment on the drive system.    

No, no. No offense taken. But you've hit the nail on the head. How can it go backwards if the it's in a forward gear? How can it move at all if there's clearance? I'm going to try and have another look today and see if I can see what's happening. The worst thing is that I've posted in several other forums and there's a lot of people with their snowblowers doing the exact same thing. Weird.

My 2005 926dle creeps also. The thing shakes more than a Go-Go dancer.

Okay I've taken the snowblower and stuck a mirror underneath and I can say with total confidence the drive plates aren't contacting - it's 100% vibration rocking the snowblower backwards. I also think I know why it suddenly started doing it. When I did my full maintenance I also lubed and greased the two chains that actually turn the wheels. In doing so I think I eliminated any friction that was there. Essentially, it's so lubed up the vibration is now enough to move the wheels. Oh well, at least I know for sure.

Good diagnostic work.  For a machine to idle up an incline due to vibration must be rattling quite a bit.   I had an old Craftsman with an L-head 10 h.p. Tecumseh engine that shook worse than a dog crapping razor blades.   My hands would go numb from the vibrations.  The new Simplicity with the B&S overhead valve engine is a pleasure to use by comparison.
