Default 1440 14HP V Twin engine HOT!

Hi

My CC runs great and all. But it seems like after I mow for awhile it tends to overheat and not want to run at all. It'll sputter, then die. And then just plain will not fire up. The starter whirls over But no kick. After a few minutes, it might start up and then immediately die and stay dead for maybe 30 minutes or when it cools down. I haven't been able to pinpoint what causes this. Is this a common issue with V Twin engines? This engine is built quite a bit different than the standard B&S lawn mower OHV engines I have dealt with in the past.

Thanks

Joe M

You engine is likely vapor locking. Do you have the heat shield in place behind the engine?

When the engine stalls, remove the gas cap and pressurize the fuel tank for about 30 seconds and see if the tractor will start back up right away.

I have to run my Kohler Command and Vanguards with the side panel removed on the fuel pump side to prevent this. I also do not have the heat shields behind the engine installed and I believe this contributes to exhaust heat recirculating around the fuel pump.

You may also have a bunch of crud in the cooling fins. Time to pull the engine, remove the tins and give it a good cleaning.

At least check to see if you have good air flow out of the front of the engine near the exhaust pipes. You should feel a pretty good breeze, if not you have plugged up fins and continuing to run it will damage the engine. Mice love to build nest's in these things and then they over heat.

Not to hyjack the thread but I did that a couple of weeks ago, couldn't believe the crud that accumulated between the fins.

Here's another example. Leaky crank seal PLUS a mouse nest.

That was pretty helpful. Looking at the shroud (grill?) there was quite a bit of grass blocking the holes. Nearly all of them. I took it off and dug it all out with a brush inside and out. I poked around the fins best I could to see if there might be a nest up in there. But it seems to not be. The exhaust in the front blows out strong. So I am guessing so far the grill was just getting blocked. I bame myself for not taking the time to check such things. Let's hope this is the problem! The rain came in suddenly so I didn't get a chance to find out. Maybe tomorrow.

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.
