Hello, long time snow shoveler first time snow blower and have a question.


I bought a
Briggs & Stratton® 27" 250cc Two-Stage Electric Start Gas Snow Blower
Model Number: 1696619


Since the cub 24 in one was sold out and didn't want to wait for more to come in, we have had one heavy slush snow fall here in wisconsin so far and it moves snow fine but even on the slightest incline the thing just won't go up it. I at first thought there was ice or something but even going into the shed it just comes to a dead stop and I have to shove it to get it going, its like the front end of the thing is too heavy for it get it over a bump.


Is this normal for briggs? I have another 30 days on my return

I would try doing the same thing when the machine is completely dry. My guess is water getting between the belt cover and the motor.

Make sure that your skid shoes are set correctly. That could be holding it up on bumps. Also check your traction cable for adjustment. You may need to tighten it a bit. Briggs had issues with both auger and traction cables last winter so make sure you are adjusting the cables correctly. There is a potential for the cable to not adjust do to an issue with the crimping on the adjuster end. When you adjust it put a piece of tape on the cable and as you adjust, make sure the tape does not start to rotate. Otherwise you will just be winding it up and it will unwind eventually.

are the cables tight?
it could be that its not tight enough and its slipping the disc.
(a good way to check this is then when it gets stuck reach and pull the cable, if it starts going then the cable is too loose.)

That is normal when the friction disc tire gets wet for it to slip. Even the slightest bit of wetness will cause it to slip.
Your best bet would be to return it and buy another brand of machine, those Briggs and Snapper were not built with quality in mind.
You would pay more money, but a Simplicity is much better than the Briggs snowblower.
Some of the Simplicity's do not have a friction disc, they use a variable speed in the belt pulley variations like on a snowmobile clutch, or in the case of new cars with a Constantly Variable Transmission, CVT.
They used to call them "Torque Converters" back in the 70's with the variable ratio's done with the V belt and clutch pulley sheaves that squeeze in and out to change the position of the belt in the same pulleys.

I cannot believe all this talk about wet friction disc's. That has never happened to me in all the years, (since '67) that I've been using a 2 stage. OMG the drive system is vertical and the thought of water clinging to a vertical spinning disc is mind blowing. It is way more likely that it was not bought at a servicing dealer or was and was not properly set up. Especially since the machine is brand new and has the obvious symptom of an improperly adjusted machine. AAHHHHHHHHHHH!!!!!!!!!
Ok I feel better now,lol.

@Zavie,

You read my mind … In all my years, running all my blowers in every imaginable condition, even on EOD, blowing water, never, ever, did I encounter any friction disc slippage on any of them.

I guess we are the only ones that are blessed by the gods … :)

Check with your Authorized Briggs and Stratton Dealer because they do have a service bulletin for snowblowers that the drive will "SLIP WHEN WET".
Bulletin # DSB 1105
CONDITION:
We have received some reports of intermittent traction drive engagement on subject models. Upon investigation, we
determined that snow or water on the belt cover may enter the motorbox and cause the friction disc drive to slip.
IF ENCOUNTERED:
If intermittent traction drive engagement is encountered, order and install one of the following update kits using the
instructions included.
WARRANTY:
File warranty per normal guidelines. Labor allowance to install the water shield kit is 45 minutes. When completing a
warranty claim, make the following selections from the warranty claim dropdown menus:
 Customer Experience Category: MOTION DRIVE
 Key Part Identification Category: TRANSMISSION/ MOTION DRIVE GROUP
 Key Part Identification Code: DRIVE RING
 Condition Code: SPECIAL PROGRAM
Your machine might require kit # 1688081 Water Shield Kit
The kit has a plate that mounts to the engine. You have to remove the drive pulleys from the engine to install the shield plate. It is supposed to help keep water from entering and dripping down on the friction disc drive plate, to help keep it from slipping when wet. It is supposed to help keep it dry.

My machine is very simular to the OP's
What is the date of the service bulletin? What are the affected models? I was just into my dealer and they exchanged my cables and said I was good to go. They are either clueless or lying I will kick their butt all over town. Thank you for posting the SB and it may even get me a new blower I am so mad.

My Ariens used to drip water onto the disc until Ariens provided a diverting baffle to stop it from happening. Been great ever since.
toro did also, the mod is a plate under the motor bent so that it routes water drips away from the drive wheel and belts,

An update. I was into the dealership and they ordered me the kit. Of course it's backordered, lol. Actually I'm interested in seeing the part when it comes in because I'll probably wait until spring to do it myself or maybe not at all. The belt cover has an excellent seal against the engine facilitated by the belt guide, (photo) which has a lip incorporated in it to help seal that area tightly against the belt cover itself. And since I've experience no issues I'm thinking more likely cable adjustment. I'll update when the part comes in.
