    Has JD redesigned the existing 47/54-inch front snow blower?

    I came across a thread where folks were discussing a new parts list for the 47/54-inch front snow blower that shows a gearbox in place of the existing chain and sprockets. The serial number break looks like 100001- for the 54-inch and 180001- for the 47-inch blower.

    These new parts lists are located at the URL shown below. I'm not seeing anything new yet in Parts Advisor.
    John Deere Parts Catalog

    If you browse the new lists you will also see that they are now listing some individual parts for the auger gear drive. Not everything but it looks like some seals, bearings and a replacement gearbox cover is now available.


    Part Number: AUC11644
    Part Price: 494.71 USD
    On Hand: 0 Check Other Stores
    Description: Parallel Shaft Gear Drive - PARALLEL SHAFT GEAR DRIVE, ENCLOSED

    They are also showing a revised up-stop with a redesigned drive shaft shield and a place to mount a cleaning tool. Although I cannot find any actual part numbers for these items.

    Gearbox

    Just bought a new gearbox this last week, the pinion bearing races where spinning in the casting, almost looks like it was machined this way, the races fell right out, the ring gear and pinion where showing a lot of chatter on the teeth, the blower has seen a lot of snow and abuse, had a couple of 47s and was able to rebuild them, 610.00 bucks, and the dealer had it on the shelf, they had some preseason discount and knocked off 98.63 off the price, happy with that, I have this on a 1025r and I have some drive train noise, everything is new accept the blower, noise goes away when your under a load, thought it was coming from the gearbox, new gearbox and the noise is still there, carrier bearings are new, but the gearbox on the pto gets warm when running the blower, the noise is really amplified through the cab, still under warranty but can't tie it up right now, any ideas ??

    If I understand what you are saying you bought a new auger gearbox for your 47-inch blower? In addition, you say your "PTO gearbox" gets hot? How old is your 47-inch snow blower? Way back when the 47-inch snow blower first came out it had a gearbox driving the impeller. Then they switched to a chain and sprockets and it has been that way for a long time. Now, new parts lists have emerged that seems to indicate they've gone back to having a gearbox driving the impeller.

    So what exactly do you have?

    This is the beveled gear drive unit replacing the chain drive.
    It is upwards of 600 bucks.
    My wonder is will you need to replace everything else to upgrade to this? I am sure it is to help aleviate the PTO shaft issue too.
    Another retrograde update due to failed designs. UGH!!

    I looked up the part number for the rear gear box and it is $494. I suspect the new up-stop plate, PTO shield and associated hardware would be equally expensive.

    I wouldn't really call the chain and sprockets a failed design. They've been using a chain and sprockets to drive the impeller on the front blower for decades and it has been surprisingly trouble free. Of those that fail a large number can be attributed to lack of proper maintenance.

    Not so sure that the earlier versions are "upgradeable" to the new gearbox but for those who might be maintenance averse this might be a good option.

    Personally I've never had a problem with the chain & sprocket drive but I know other's have. Seasonal lubrication and some attention to the chain tension adjustment have been all I've done to keep my SB's running reliably.

    Things would be great with a chain set up if they used real sprokets, not hand welded junk. You can tell they are not made by a reputable company as they did not even think to use a jig when welding, to ensure centering before welding.
    Also I truely believe if they are changing the setup back it most likely is to try to remedy the PTO issues with the double cardigan joint issues. Either that and/or they are slowly making changes to allow for moving from the quick hitch to the front 3 pt hitch. Maybe someone is finally getting the message that the front hitch and cheapening things is drawing bad publicity to the brand and the bean counters are not to make engineering decisions.
    Sorry if this offends anyone, but the squeeky wheel usually (eventually) gets the oil. I agree with HH'S assesment, that there should not be so much garbage on a "high quality machine". We have other color tractors to draw from if we want that kind of thing.

    There is no disputing that! Those out of round sprockets are a PITA when adjusting the chain tension.

    Also I truely believe if they are changing the setup back it most likely is to try to remedy the PTO issues with the double cardigan joint issues. Either that and/or they are slowly making changes to allow for moving from the quick hitch to the front 3 pt hitch. Maybe someone is finally getting the message that the front hitch and cheapening things is drawing bad publicity to the brand and the bean counters are not to make engineering decisions.
    I'm not understanding how the gearbox would change the PTO setup. Currently you have a stub that sticks out of the small sprocket to which the short PTO attaches. With the gearbox you have a short stub that sticks out to which the short PTO attaches. Everything behind the uplift remains the same. It doesn't appear like they are changing anything on the quick hitch. This parts list was actually in the X700 section and X-series, 1-series and Gen-1 2-series can only use the existing quick hitch. They have no option for a front 3PH (especially the X-series).

    Remember, they already have that green Rad-Tech front blower that uses an entirely different front attachment method but is currently only available for the 1-series.

    It will be interesting to see these changes in person once the new blowers start making their way into the wild.

    I agree that some of the drive pinions have too much radial runout from what I've heard. I've been lucky in that respect as mine (early 47, late 47 and current 54) haven't had the issue as to affect accurate chain adjustment.

    As far as the short implement driveshaft and mid-driveshafts with double-cardan joints are concerned I don't don't see those changing if the existing quick hitches are going to be retained.

    Exactly. For the 1 series, I see that the problematic quick hitch arrangement going away in favor of the 3 pt hitch I understand is now being offered elsewhere. Maybe it was for the 2025R, but not much of a stretch to the sibling 1025R. Makes sense to me, as then they may be able to fix the shaft issues as well. The current quick hitch is not heavy enough, and they know it.
