John Deere 928E issues

Hi all,
First snowblower, and first post to go with it!
I just purchased a John Deere 928E at the local John Deere dealership. I figured that spending the extra cash on a JD would get me a top notch machine with top notch performance.
I have used it twice. The first time out the motor began jerking a few different times, but would then start behaving again.
The second time out (this morning), it jerked a couple times, but then the chute started having trouble turning. When turning it to the right, it would only go about 3/4 max and then get stuck, where I couldn't turn it either way. I would grab and turn it enough for the gear to start working again and it would turn the OTHER way, but still get stuck when going to the right.
After finishing up, I decided to take a look at it a few hours later, and now it has ceased to work altogether. We are supposed to be getting another large snowfall Sunday /Monday.
Anyone else have this problem? Anyone have any suggestions? Anyone else feel as though they got taken for a ride when they bought a John Deere?
Thanks for any help anyone can offer.

A big thanks Borat and MacLorry27!
The scraper blade makes sense, as the whole machine would start to jerk....I was concerned because it seemed like there wasn't any bumps or anything in the way. But, I've had it out a couple more times and it only seems to do it once in a while...so I will attribute the cause to that scraper blade. I may try to raise the skids if it becomes problematic.
And, the other day, after finishing the driveway (while having to physically grab and move the chute every time I needed to change it's trajectory, I decided to take a look and you hit it right on the head MacLorry....the little worm gear was not making contact with the "teeth" properly. Maybe it got jostled in transit, or whatever....so I loosened the bolt and moved the gear slightly inward, and it seems to be just fine now! I haven't had to use it yet, but I think that was it.
So again, a big thanks to both of you, Happy Holidays and "Happy Snowblowing"!

I just picked up up a John Deere 928E from a local Lowes up here in Canada, just happened to be in the store and they had 9 in stock. This year snowblowers are few and scarce here you get what you can and not what you want. I know they're supposed to be good machines, however when I took it home in the crate and started to assemble it I realized I was missing some parts. First of all the crank on the dash to turn the chute was missing and the chute itself looked like it been hit by something probably a forklift, it was bent and and there was a tear in it. Furthermore it was even missing the black guide clips for the chute so that it can be attached to the blower itself. Now I'm wondering how good is this machine if right out of the box its missing this many pieces. My question to myself is what else is it missing that I can't see. Catch 22, I want a snowblower but can't get it replaced with anything else because the store doesn't have anymore. Called them up and spoke to a manager and a John Deere rep is supposed to come over and take a look at the machine. Anyone else have a missing parts problem?

If I were you I'd take the machine back immediately for a full refund, then worry about finding another one. You don't need the hassles of having various companies attempt to fix your problems. You shouldn't be having problems. Paul

Check your receipt, but in the U.S. Lowe’s has a 30 day return policy for power equipment. Just pack everything up and take it back to the store. You don’t even need a reason for returning it, but the fact that it’s missing parts and damaged is full justification in anyone’s book. Have them give you another 928 and have them set it up. The John Deere is made by Simplicity, which has about as good a reputation as any brand of snow thrower. Likely the crate for yours was damaged in shipping and some parts dropped out somewhere. That’s why I would have Lowe’s set it up. You can double check the setup when you get the 928 home. However, if you want to set it up yourself, inspect the next create for any damage before you take it home. Mac

Out of curiosity.... Does anyone know the HP rating on the 928E? When I purchased it, the John Deere associate told me 9HP (JD dealership), the Lowe's technician/mechanic told me 11.5 HP. I emailed John Deere, and they wouldn't give me an answer. They told me they measured the power in CC's, not HP.
I figure someone on THIS forum MUST know the definitive answer!!
Thanks!

Even though you can't describe power in cc's this might have been the good answer just the same :-) There's some question about the different horsepower ratings for engines with the same displacement (cc's, cubic centimeters) but no one is arguing over the displacements themselves, and usually more displacement equals more power. I'd guess your engine is more like 11-12 hp than something less. Paul

The JD 928e uses the B&S 305cc Snow Series engine model number 200000. This engine is rated at 13.5 ft-lbs. of torque in accordance with SAE J1995. Under that standard torque is measured at 3060 RPM and horsepower is measured at 3600 RPM. If we assume a flat torque curve, which is not likely, you can calculate horsepower using the following equation. HP = Torque ft-lbs. x RPM / 5252 Substituting the values you would get the following. (13.5 x 3600) / 5252, which is 48600 / 5252, which is 9.25 horsepower. It’s likely that torque is less than 13.5 at 3600 RPM, so I would round this off to 9 horsepower. Now you know where the 9 in 928 comes from, and the 28 is the width in inches. By the way, to get 11 horsepower you would need 16.0 ft-lbs. Torque at 3600 RPM. To get another 2 HP out of this engine at the same RPM requires getting more air/fuel into it. That usually means either a bigger carburetor and/or a less restrictive exhaust system and/or a different cam profile. However, B&S could just put a stop or different linkage on the 9 HP engine that prevents the throttle from opening 100%. Why, it’s all in marketing. Customers are willing to pay more for more HP, but it’s cheaper to have fewer engine models. The solution is to build a 11 HP engine and then limit the maximum throttle setting for the 9 HP model. Then again, maybe there is no difference at all and the 9 HP is really the 11 HP engine, but it’s only marketed as 9HP. You would need a dynamo to figure it out.

If there is a true difference in power between engines of the same displacement, shouldn't the part numbers vary? If the more powerful engine has a different cam or carburetor would that not be reflected in the part number? If I had paid for an 11 h.p. engine and was supplied a carb or cam for an 9 h.p. I wouldn't be too happy with that. If the part numbers don't change from one rating to the next, one would have to assume that the engine is either at one end of the power spectrum or the other right? By the way, my engine is rated at 9.5 h.p. From my experience with other engines in this class, It's a pretty potent 9.5.
