I saw the posting by Texas Deere and Horse about plastic welding and it got me thinking, "the STX38 needs to have its hood repaired. I wonder ..." The hood is made of Xenoy, at least that is what is stamped inside the hood.

Anyway, I dug out my table saw, an old treadmill, and some Acrylic glue. Once the loose pieces and old patches were removed, I sanded the little ridge of the bottom so the plastic patch would conform nicely. I cut 2" strips of plastic from the treadmill motor cover. The heat gun melted them enough to mold easily. Leather gloves work best for forming. The Acrylic glue bonded the parts quickly but dries fast. I found that wetting both surfaces worked best, kind of like contact cement. Once the patches were installed, I filed the excess off with a hand file.

Lessons learned:
1. Don't wipe the glue runs while they are still wet!
2. Clean the mating surfaces with Acetone, but don't re-wipe over the same area.
3. Leave extra & file smooth.

I like the result, but would be happier if I could get rid of the black streaks & speckles.

Thanks for posting. I don't think I've ever seen that done before. What is acrylic glue and where do you get it?

The label says "Weld-on 3". It is made by IPS, P.O.Box 379, 17109 S Main St. Gardena, CA 90248. It comes in a 1/4 pint tin can with a screw top lids. I got it from a friend who was into building aquariums. It is available on Amazon. As for what is in it, I'd guess nothing you'd want to drink.

Your repair came out great. Not being real familiar with John Deere I would not have noticed anything out of the ordinary if you hadn't let us in on the project. I like your oil drain also. :thumbs:

Very well done; I have a suggestion if I may and that is where the two bolts come out on each side is if possible to use carriage bolts with the head on the outside, I think it would give it smoother look.

Yea it would work on the LX'S and GT's but think about what usualy breaks on them, around the top at the louvered areas.

I considered carriage bolt, but they interfered with the hinge mechanism.

yea, I repaired a GT242 hood last summer that was broke both at hinges and the louvers. Just picked up a LX178 and the louvers are busted. They are almost as bad as the Sears SS/ST upper grills.

 

Nice repair!!!

Have you tried these. Most box stores won't have them but some older hardware stores would or you could order. Nice job on the repairs looks great.

Our local John Deere dealer tried repairing the cracked hood on my LX178 after the body shop declined the job. It didn't work and I've ordered a new hood. My question is:

"Is there anything that I can do NOW to re enforce my new hood to make it more robust?"

Any and all opinions are welcome!

If you are talking about a repair, I will usually embed wire screen or cotter pins to help support the repair then melt plastic over the repair.
