Broken transmission mounts on my 1440
 

:bash2: I'm having a problem with my 1440 while pushing snow. First let me say , I bought this tractor specifically for this purpose, and it is NOT working out very well. The snow blade attaches to the tear hitch via a long square tube, and runs the length of the tractor all the way to the front. One thought is that the frame could possibly be bent, but I really don't want to go with this theory because the frame is quite substantial and I don't think the 14 horse engine could produce that much power! The next theory is that the torque being produced by the weight of the snow on the rear end of the tractor could be causing the mounts to break due to the upward pressure being applied. Both theories were thought of by a guy who works on cubs all the time, and I am looking for anyone out there who may have had this same problem.
Anyone have any suggestions? I have ordered replacement parts and should have them in about a week. I really don't want to spend the money and time putting it back together just to have the same problem again!!

I moved this to the CCC area because a 1440 is an MTD/CCC. Broken trans mounts are very common in this series of tractor. It happens when the bolts get loose. Depending on how badly they are broken it may be able to be saved with a set of GT braces from Xtreme. Get me some pics. I need to see what is broken.

Welcome to OCC Jeff! As Sam said, pictures of the problem area would be great.
Also, it sounds like it has a non cub cadet snow blade attached if it attaches to the rear hitch?:bigthink:

Cub sold a snow blade that went to the hitch and was lifted by the rockshaft just like the deck is,they have a square tube on the mount that a flat plate slips into and then latches into the quick connect on the tractor to control side to side movement. I have a couple of those here.

Would like to see pics of that Mark. Never seen that setup before.:bigthink:

I would like to see that as well! That could be possibly save the problem. As soon as I get home from church, I will post some pics of my problem.:bigthink:

Welcome to OCC! Good luck with your 1440!

pictures of the broken brackets
 

here are the broken brackets and the problem source, I think.....

Any other ideas? I really don't want to put on the new brackets until I figure out the cause of this!

That's a cub cadet blade but a blade setup off a LT and doesn't belong on a 1440. I'm assuming that is why the trans mounts broke. There is no support for that thing.:bigthink:

OK, so being I am new to this thing, what is it suppose to have. Someone mentioned a mounting system that utilized the deck mounting system. Any idea what that would look like?

By the way, what is an LT?

Lawn Tractor!!!

This is what you need.

Sorry Jeff. LT stands for lawn tractor and your 1440 is a garden tractor.

OK Jeff you have the wrong plow setup for that tractor as the others have said. I need to see what the axle tube mounts look like. It has 2 bolts that go through the frame on each side. As long as the bolts are not broken off you will be able to fix it easy but looking at the broken adapter brackets I'm concerned. The good news is that the aluminum adapter that the pump mounts to is in one piece. This pic is from a Super but the bolts I want you to look at are to two at the top to the right in this pic, they are the same on all of the aluminum rears.

A little more info about the area you need to check. The first pic shows where the bolts go through the frame. The second pic shows the top of the axle tube. I have seen the tube broken in this area if the mounts that are broken on your tractor let go. Look at the areas circled in red and try to get me pics.

The plow that you have would have not caused a problem. What happens is that most of 1440's -1864's have Hydro Gear pumps. The Hydro gear pumps do not have the springs on the trunnion like the Sundstrands do. Because of this if you slam it from forward to reverse and reverse to forward it's like popping the clutch on a gear drive. This causes the bolts to loosen and eventually they will fall out or break off and at worst they bust the axle tubes. The 1863 that I turned into 1641 had broken bolts and I had to pull the axle tubes off it to get the broken bolts out, major PITA job.

From the looks of it, all that's broken is the metal clips to hold the tranny...not the trans itself which is GOOD!!! The correct blade would put pressure on the front qa points and the rock shaft...the transaxle shouldn't be load bearing like it is with that wrong style blade

I wouldn't bet on that, in order to have that much space between the broken parts the mounts at the back had to twist a lot. I will be very surprised if he doesn't have broken bolts or a broken axle tube where the bolts go through the frame into the tubes. I hope he got lucky.

I'm with you Sam. I won't be surprised there are some bolts snapped off. Having the proper blade setup is hard enough on the rears with all the ramming going on let alone having the incorrect setup on top of that. Hopefully Jeff can get some pics.

I doubt that the plow is what caused this problem. I've seen the same failure on 1641's 1863's etc. This came out of an 1863 that was only used to mow. The Hydro Gears can be very abrupt when changing directions, because of this they are prone to this sort of problem. Just my 2 cents but I think they are as bad or worse than the Supers when it comes to problems with the trans mounts. Ask me why I have rear end braces on both of my 1641's. :biggrin2:

The pics. of the blade on the 1440 are like the ones i have, but the QA mount is missing on his setup and i'm not sure but it should hook up to the mower lift links without using the extra flat straps. This style blade could be used on lawn or garden tractors depending on the mounting frame you bought. it was a cheaper, lighter version for someone to use on gt's.

I agree with you Sam I don't think the blade setup led to the transmission mount failure but also don't think it helped it either. I don't see any support at all on the front and when snowplowing people are going to ram snow and hit stuff like uneven or level surfaces and all that jolting transferred back thru the channel that leads to the rearend I can't believe did it any good either. My 0.02. hehe

I would like to see pics of your setups Mark. I have never seen this setup on a garden tractor and looking at the cub cadet site and partstree I can't even see it listed so I'm just more curious then anything what this setup looks like and why mtd would offer this setup. :bigthink:

Sorry for my ignorance guys, but that is why I joined. I will have a look today and post pics.

Thanks

Jeff

You may have to remove the rear hitch plate to get a good look at the top of the axel tubes. Not a big deal only 4 bolts. 9/16" wrench and you are all set.

We are all here to learn Jeff that's what is great about this place.
I have been around cubs all of my life and never seen that plow setup on a GT so I learned something today.:beerchug:
As Sam said hopefully it didn't shear frame to rearend bolts or axle tubes.

No such thing, as a stupid question, Jeff. We're all here to help each other. :ThumbsUp:

Jeff

Hang in there we'll help you get it fixed better than new. We have some very talented people on this forum. :beerchug:

Some pics. of the mount parts.I can't get to the only complete one it's under a couple feet of snow:biggrin2:. most of these blades i've seen were on old narrow frame tractors.Maybe because of hard to find mounts?The extension on the tube under the tractor allowed for use on several applications

That looks like a pretty good setup.

Broken mounts on my 1440
 

Par for course, an MTD :angry: that falls apart!

Here are some pics of the damage and what caused it. Notice there are missing bolts from the right side, a broken bolt on the right as well as a missing bolt, and just my luck, the right side housing was cracked! I have a good source here in Illinois in Montrose, who has lots of tractors; infact he calls it the cub boneyard!
I actually traded two snow blades for one complete setup. Almost complete, just missing the raise and lowering rod. No problem to make one of those! Basically, less than a hundred dollars and the problem should be corrected, never to return (I hope):beerchug:

That is the setup I was using. I believe it is a part of my problem.

I traded two snow blade setups. one was like the one you have pictured here, and the second was the correct front end parts, but was modified to fit another unknown type of tractor. The one I got has everything except the push pull rod, which I can easily fabricate!

Someone mentioned a bracket setup by Extreme. I am interested in using this setup and would like more info. Pictures would be good!

I have now got to the problem that caused the broken brackets; two missing bolts, one sheared bolt , and loose hardware. I am replacing both axle tubes, and both trany mounts. I also have to replace the trany cooling fan. I have just over $120 in order to get it back into new condition. Both the axle tubes had stress cracks inside, and needed to be replaced. The driveline couplers are in good shape, so I dont need to spend that extra money. I actually found a shop that had the gaskets for the rear end inspection plate and the axle tube gaskets on hand, and for less than $30. Pretty happy about all that! Not happy about having to go through all this right now!!

Thanks everyone for the insight! You were very helpful.:beerchug::High5::High5:

Do you have the correct paint number for the 1440? Yours looks really close to being the color I am looking for?:bigthink:

Jeff, I have a similar problem with my axle carriers on my 2072. Just waiting for the weather to warm up to tackle it. The guys here provided me with some great info.

Good Luck!

Jeff

I sent you a PM, give me a call. I have a couple tips for you on how to fix this up.

Good news! I got the brackets for the tranny today, along with the fan for the tranny cooling! Now all I need is the brackets from Xtreme Autoworks. It is intransit via UPS, but I don't know how long that will take to get here. They didn't supply a UPS tracking #. As soon as I get that, we will gitter back together and running again!! Thabks for all the help guys!

Jeff

Holler if I can help.

Mac

Good to hear!:beerchug:
