I was asked why I had excluded the IH Lawn-boy mowers when I created my Lawn-boy picture thread. Internationals are considered Cub Cadet mowers. Parts are available through them. Click Here - Direct Link to just the pictures If you have a picture for a unit that is missing a picture...
Well I have seen worse. Definitely worth refurbishing this one however. The correct handle should not be too hard to find. Same with the recoil. The gas cap I am pretty sure would not have been correct for that mower anyway. That is a cap from an F series, 1978 to 1982. It the threads are not destroyed too far down you can sand the filler neck flat so the cap will seal. The deck would be the big issue. If you can find a welder that does magnesium that may be the way to go. Some have mentioned Lab metal to fill the holes. Depends what your intent is after it is done. You don't want to waste time and effort into a less than acceptable repair only to have it fail. If your just doing a cosmetic upgrade then strength of repair would not be so critical. You could also keep a look out for a deck from a donor mower which is what I did with mine. Keep us posted on your progress. Bill
Also just noticed that yours is a 19 inch model. NICE! D-600 engine. I am guessing engine parts would be similar to the Lawnboy 1972 model year.
They are cool machines! I had one briefly, and gave it to a better home (thanks Bill!), where it received its proper care and refurbishing. Those are arguably one of the rarest lawn boy/cub mowers out there, with exception to the Promo and Liberty.
There have been some in-depth discussions with lots of good info over the years. Some creative searching should turn up a lot of info. Maybe a search for IH + BaldGuy would be a good starting point. We had a member years ago with that username who was an incredible font of knowledge as he worked in the factory. Great guy, and I miss him.
That is very interesting. Model 336 does not appear in the IH Lawnboy picture thread. I see the model tag reflects that it was made in Canada. Perhaps that big C in the serial number also indicates that. That shroud appears to be in very good shape. I would keep an eye out for a donor mower with the same deck in good shape and replace the deck. Leave the shroud as it is and maybe install a new set of decals. Definitely worth preserving. Hopefully the powers that be will add your pictures to the IH Lawnboy picture thread. Hint, hint!! Bill
