I bought one in 2014 and have 111 hours on it. Yesterday I was giving the yard its first cut with it for this season and I stopped for a bit and when I went back to finish it would not move in either direction.

Any other users here have the same problem? Could there be something other than the transmission that is wrong? I bought this at a JD dealership and the service manager seems kind of

sheepish and wants the vin number before he will talk about it.

The little rod (I can't remember what it's called) in the back of the tractor...make sure it is pushed in all the way. When it is pulled out, you are free-wheeling, which means that you can move the tractor by hand/push it, but the tranny doesn't work.

I would look under the pedal area of the platform to make sure the linkage didn't get disconnected, which is unlikely.

There is also a "Lever Kit" which moves the machine back and forth on top of the transmission which could be the issue, make sure to check that. Here is a link to the transmission page in the parts manual and it's item number 7 in the illustration.

John Deere Parts Catalog



There is also a drive belt kit and some other pieces to check which would prevent the machine from moving in either direction. You will see that there are few servicable items on the actual rear drive assembly and the transmission itself is priced at $372.14 and it is part number AUC11077 from Green Parts.

It's a common enough part that Amazon sells the entire rear transmission assembly, ready to install here

Amazon.com : General Transmissions Transaxle RT400 GT87137 : Garden Outdoor


Sadly, these machines are known for having a weak transmission and one which is prone to failure. The machines are real susceptible to failure if they are used to mow inclines or if the machine pulls anything of any weight or resistance.

The D105 use a transmission which is unique to those models which is made by General Transmission and is largely plastic gears and the unit is considered "Non Servicable",meaning the unit is supposedly factory sealed.

There are numerous videos and threads about working on these transmissions. Seems like there is a common gear failure, which if you can do the work yourself, makes the unit worth considering a rebuild. If you are going to need the dealer to repair the unit, make sure to get an estimate before you proceed as the labor costs along with the parts can sadly, make the cost to replace the transmission exceed the value of the machine for some.

Thanks for the replys. I'm starting to get sick to my stomach just thinking about it. Once I get this thing operational I figure I'll figure out someone that I really dislike that wants a used lawn mower and sell it to them. This is the first real problem I've had with this machine, but all of the tires have had tubes put in them because of leaks from weather cracking. Plus it appears that one can not adjust the front alignment. Must have been designed and made for JD in some country named trashcanistan or cheapistan, I expect that from Harbor Freight or Northern Tools which is why I bought this from an authorized John Deere dealer. Plastic throw away tranny, unbelievable.

It was designed for a price point. If you want quality and adjustability you need to open your wallet. One adjustable tierod end costs more then the draglink on these models.

As for weather cracks, how is the mower stored? What’s the ground like under it? One member just replaced 25 year old 180 tires, it’s also a riding mower, but cost more in 95 then a d105 does now without even figuring in inflation.

It's a shame the quality isn't better now days, even though it is a low end model. I've got a Lowes branded riding mower made by American yard products I bought in 1994. It still runs and mows. It has a simple manual transmission. Nothing fancy but just goes and goes. I've replaced the drive belt just one time. Sorry to hear about your luck.

This mower has been stored either in my garage or in my machine shed. It has been outside only when in use. When I bought it I was aware that many name brand companies will market a cheap version of their products to big box stores and they should be avoided. Thats why I bought this mower at a dealership.

I've been told the big box JD's are the exact same ones they sell at the dealership now.

Odis, I can't prove or disprove this statement, only repeat what I've read online at various JD forums: If it says John Deere, it's made by John Deere. If you buy a D105 at Lowe's, Home Depot, Honest Joe's
Surplus Tractors, or a John Deere dealership, it's the same tractor! JD doesn't make a different quality level based on the end seller...a D105 is a D105.

BTW, I was of the same opinion, box stores where a lower grade. I've been wrong before, and I'll probably be wrong again! Bob

If the JD model number is the same then the tractor is exactly the same at Lowe’s or your dealer. If you buy at Lowe’s your dealer still does the setup, and warranty work.

JD long ago decided if they don’t want to give up the cheap market they need a cheap mower, and in order to hit that price point, it has to be made cheaply just like the competitors.

As for the tires, that surprising. I’ve only seen that type of life when rubber sits on dirt. My brothers 10 year old troybilt pony just needed it’s first tube.

my cousin's sit and spin(ztrak) tires just bit the dust -as in bald, and cracks in sidewalls too. she just replaced both of them this spring for mowing. it was the lower end z-trak of jd's line.

heck i got tubes in my rear tires on the 2520-it's from 2006 yr i bought it, and what's bad is just one rear tire got pin holes in the side wall on them. so i just tubed both of them.

Dealership probably wants the VIN to determine if it would be covered by the recall.

Take Taryl’s advice, problem solved.

It is not JD’s fault for the low quality it is the consumers. People are willing to accept things like plastic bushings vs. wheel bearings in from tires and thinner decks and ect.

Now consumers are willing to accept plastic transaxles.
