  • O.T. Honda Harmoney Mower Plastic

    My friend recently purchased a new riding mower and just gave me his old, well-used Honda Harmony riding mower. It's the type with the red plastic covers. It looks like a large lady bug.

    In any case, I will be workng on it as my next project during the winter. I plan on replacing the tires, seat, battery and belts and also fixing the crack in the rear section of the plastic cover that fits over the engine.

    I made a plastic welding unit by adding a snout to my heat gun. It has two ranges: 650 degrees F. and 1000 degrees F. I plan to weld the crack with it. So, my question is this: What sort of plastic is it?

    I bought a bag of 50 plastic rods from H.F. the other day in preparation for fixing the crack. It has a selection of rods made from polypropylene, poly vinyl chloride and ABS. (sorry, I dont' know the full name for ABS).

    If anyone has any information regarding the type of plastic that Honda used, I'd appreciate it. Also if you have any tips on welding plastic they would be much appreciated. Thanks in advance.

    There are thermoplastics and there are thermosets. Thermosets are not remeltable. Use epoxy or fiberglass resin for them. I believe you can only remelt and weld thermoplastics. I think your Honda deck is a thermoset.

      I guess I answered my own question by looking a bit farther. I looked again on Google and a number of people say that the covers are made out of a plastic mixture called Xenoy. Checking on Wikipedia tells me that Xenoy is a combination of Polyethylene terephthalate (PET) and Polycarbonate (PC) When I get to the crack repair, I'll just have to give it a try and see. Thanks to all.

        I've used the Plastex repair system and been quite impressed.

            THAT is why it's always called ABS. :-)

                I've repaired that kind of thing with simple car body filler, but Evan's stuff looks even better, depends on the price though.Alistair good luck and have fun.Alistair
