Tim T., if it were mine I would spray a penetrating oil like PB Blaster, Kroil, Liquid Wrench or your favorite brand, wherever I could get it in and around the rockshaft. Then let it set a day and reapply, repeat this over a few days and test it occasionally to see if it has freed up. Perhaps someone here has had the same issue and will post a reply.
Nate, nice score! I especially like that 1872 with loader. So far I've purchased three Cubs at a JD dealer. First one was a 125 with chains, IH wheel weights, a windbreaker cab and a Dexter Sweepster. Second one was a 102 with a 42" mower deck. The third one was a 1450 with QA42A, 50 mower deck and JD cast iron wheel weights.
It helps that my brother is the parts manager there and gives me a heads up when they take IH Cub Cadets in on trade.
This is not to OTF, but I noticed a problem with my trailer when I was at a show this past weekend. The left rear tire is worn slick. All the rest of the tires look great. Any suggestions as what to look for would be greatly appreciated.
Here's the left rear and both left tires:
And, here's a picture of the right rears. They show no problem:
I'll be away from my computer for most of the day but should be able to check in this evening to see if anyone has some suggestions as to what might be wrong. I'm hoping I can correct it without having to unload all the Cub Cadets that I store on it.
I went to start the 149 this am for a little exercise and battery charging. When I turned the key it back fired with an attitude. I've never heard such a loud back fire. I knew immediately that it blew the spark plug right out of the head and sure enough, the spark plug along with the helicoil was lying on top of the engine.
Has anyone had this happen to them? I went through this 149 three years ago and have been mowing with it most of that time. I installed a 48" deck and it has been doing great (until now). I didn't do anything any differently as I have done for the past 3 years so I just don't understand. Turn the gas on, pull the choke, give a little throttle and, in this case, BOOM!!! I haven't used the tractor for a couple of months and that's why I was starting it to begin with. I always use high test with MMO too.
What would cause such a massive back fire??? Thank goodness for the heavy metal hoods.
Paul, just to add to that, if the wear was the same all around tire I would think a bent axle, but the wear looks like it is mainly one area making me thing more along a bent rim, a bad tire, or possibly a bad hub.
Wayne, I don't think anyone will have the definitive answer as to why. Metal fatigue, incorrect installation of the heli-coil?? Plug was loosening in the threads and causing damage? But I will say the cylinder had an air + fuel charge large enough and strong enough and it was months old?!?! I guess the MMO is helping keep the gas fresh enough to cause damage
