149 Cub Cadet Engine moving
Hi everyone,
I have a 1971 149 Cub Cadet. The problem is that I can lift the carburetor side of the engine about 1-2 inches up. I looked under the frame and I believe I saw the two engine mount nuts on the underside but they have been welded into place. (see attached photos) So my question are these the engine mount bolts/nuts? Does anyone have ideas on how I can fix this problem? Any advice is appreciated

Yes, those bolts under the frame are the engine mounting bolts. There are a total of 4, 2 in front and 2 in back. Have you found the bolts on the other side of the engine??
Seeing as they are welded, you will probably have to grind/cut them off and get them out, and replace them with new bolts. If the bolts on the other side are welded too, then same there.

If the bolts are welded to the frame AND you can still move the engine, the threads in the pan are stripped or the bolts are broken off.
Can you get up in there with a grinder or cut off wheel to remove the bolt heads? Or maybe if the welds are just complete chiken crap you might be able to twist them off with a wrench or vise grips?? Did you find the other 2 bolts? You really need to get that engine out of there so you can see WTH is going on before the driveline takes a crap on you from being out of alignment. It's just amazing what folks have done over the decades to these poor Cubs thinking they have "fixed" the problem, whatever it is. When in fact they have just created a mess for the next owner. You, Sir, are beginning to discover this. Good luck!

Thanks for the information.
I looked again at it and found all four bolts, all of them are welded pretty solidly to the frame. Looked to see if they were sheared off and they are not. I think it is what you said that the bolts are stripped out on the engine. The picture attached (it should be rotated 90 degrees clockwise) shows the engine can move up and down on the bolt welded to the frame. Also, I don't think they are sheared because the engine only moves up down and not forward, or backward or side to side. The two bolts on the carborater side are stripped out completely. So now the big question, how can I fix the engine being stripped out on the bolts? My idea is to pull the engine out and try to fix the threads in the engine with a tap. Is this wrong or more importantly is there an easier or better way to do this?

From the look of things in your pix, the previous owner gets the cobble award of the year.
If it were me, I'd get the engine out anyway you can and replace the oil pan. If it is an aluminum pan, put back in a cast iron pan, searching the internet like ebay or face plant it you do such, should be productive. No telling how bad the bolt holes are wallowed out in that old pan and I highly doubt any tapping,helicoil or inserts will work. Then go about repairing the frame properly, welding and careful grinding till it is like new.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
