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

... when you bend down to operate the axle-mounted lock pin at the left wheel, on the '05 and older models. This has really bothered me, and the new models no longer have this problem due to the new axle design and remote control system.

My fix was to fabricate a small deflector from a 3" x 3" piece of thin stainless steel. I carefully bent it into an "S" shape in my bench vise and pop-rivited it to 2 existing holes in the muffler face - the two holes are the outer ones closest to the rear of the thrower. I drilled the holes oversized and installed the deflector with 3/16 inch stainless pop rivets. These are very hard to find, but a bolt or boat supply company (like West Marine) will have them at about US$1 each.  Plain steel or aluminum rivets will not hold up in this environment - the heat and vibration will loosen and corrode them severely in a couple of winters. The steel should be available in the scrap bin of any metal fabrication shop.

I made sure the deflector did not stick out to the left beyond 1 inch, so that the black muffler heat shield would still fit correctly.

The mod works GREAT! No hot carbon monoxide blasted into the eyes and lungs. The exhaust stream is broken up rather than a concentrated stream, and most of it exits straight forward and up, with a little bit going down. I have not thrown snow yet, but I don't see how the mod can have any measureable impact on engine performance.

I highly recommend this mod if you own an older DLE.

Every lawn mower manufacturer took steps MANY years ago to prevent people from walking around their running mowers to clear the discharge chute - too many people were losing hands. They put plastic skirts behind the decks to prevent people in sandles from getting their toes chopped off. Chain saw manufacturers put chain brakes on the bars to prevent homeowners from chopping off their legs when they set down their saws. Trimmer manufacturers put deflectors at the trim heads to keep flying rocks from blinding the operator. Consumers as a whole have NO common sense and steps like these are necessary!

Ariens has made this machine for 3 decades. I have no idea if this exhaust thing was an issue then or even 5 years ago -  maybe at some point they went to a different engine design or supplier and this problem suddenly appeared. Their solution was to tell the owner to shut off the engine every time they want to operate the diff lock. This is the lawyers tallking, not the engineers. If an owner can simply take one step sideways, grab the left grip with the right hand, and reach down to operate the lock with the engine running, HE WILL DO SO.

Ariens should recognise this, and that is why I contacted them. Simply telling the owner to shut the engine off is unacceptable, especially when a simple 5 minute deflector mod could eliminate the problem entirely.

You can call me an idiot all you want in a private email, and then I will feel free to call you names in return. Do it in public and it is not just juvenile and impolite, it is totally  inappropriate and you owe me an apology.

JohnED,

Drillertoo,

You are entitled to your opinion, but personally I think you were rude and disrespectful, especially for a person who has a total of four posts here.

John is also entitled to his opinion, and even though this is not a new concern to him, factoring in the new changes Ariens brought to the new 2005 snowblowers, it is still an interesting topic of discussion. His bringing it up again is also warranted because of the solution he came up with.

If we still had the "old mods" who used to be here, (a fine bunch of guys I might add)  your insolence would not have been tolorated.

Flaming has never been allowed here in the past......if that has changed it would just be another reason why some of the best people here have gone over to the "other" OPE forum.

There is a big difference between "flaming" and disagreeing with what a person posts......hopefully you will learn the difference.

In your case I agree. You made a modification to keep the lack of common sense from being a problem, I'm sure it was a good idea. Now it blows upward into your face. I stand corrected, no idiocy there. 

That deflector was nicely done & I applaud someone trying to improve something.

BUT - Stopping & restarting is an inconvienience when it comes to safety? I'm sorry, but that is just plain LAZY & irresponsible. With this new deflector addition, the exhaust will now blow in your face when one goes to clear the auger, which will probably be done with the engine running. ANY TIME YOU LEAVE THE OPERATOR POSITION FOR ANY REASON, THE ENGINE SHOULD BE SHUT DOWN FOR SAFETY!! I feel that someone's safety is PARAMOUNT & ALL measures should be taken to keep yourself safe! Don't wait for someone else to do it for you, be smart & work safely folks!

Operating OPE is dangerous & some common sense must ALWAYS be excercised. Unfortunately in today's society, no one assumes ANY accountability - its always someone else's fault no matter what.

Sir, to reiterate, your deflector does not "solve" the problem. It redirects the exhaust stream in a way that may cause you to be breathing carbon monoxide while the machine is running and moving forward, if I understand the picture.  The exhaust isn't just an incovenience: it's deadly. No one else should attempt this modification without serious consideration about the dangers of an unengineered approach.

The change in back pressure of the exhaust may not impact the performance of the engine. But you have not even used it to blow snow yet, have you? And you've heard from the Ariens engineering staff about the other considerations.

The new machines have completely resolved the problem . If it is so important to you, why not sell the machine and get one of the new models? It probably wouldn't cost you more than a few hundred dollars.

There is plenty of discourtesy and contempt in this thread already, on several fronts.  You have made your point: reiterating it again and again is not helpful or interesting.

This is all very interesting and I had no idea my posts would stir up such a hotbed of emotion. It was NEVER my intent, which is one reason I resented being publicly called an idiot, for which that poster has not yet apologized....

Everyone is certainly welcome to voice their varied opinions. Mine is quite simply that the redirected CO isn't a factor in the outdoors. I did a similar mod on a Troybilt Horse rototiller and it worked fine and I never passed out or even noticed any additional fumes while in the garden, over a period of over 12  years. We will see with this one..

I will fully test my mod when I get a chance and make another post after the first snowstorm, regarding the exhaust.

Thanks for all the feedback.

The Ariens rep has stayed in the loop. While not condoning my mod in any way, he gave me this information which may be of help to owners of late model 926DLEs at least - I don't know about fitment on other models.

Hi,

If anyone buys that deflector for their Ariens 926, would you please post a Pic.

I have a 9HP  OHV Tec engine on a husky and want to see if the deflector would work on my blower or other blowers.

                                                Thanks
