Head gasket woes
I changed the head gasket on my 1450 the other day. After mowing for a couple hours, it started knocking and sucked all the oil out of the crankcase. No leaks and after filling the crankcase up, it runs enough to get in the shed. I never heard of this before. Any thoughts on this?

You are supposed to re-torque the head after 15 minutes of use. Perhaps you can try that? Might be leaking there.

This is a long shot. Did you check all the air cleaner openings? A friend had a newer Cub suck all the oil out of the engine because a mouse had plugged the air cleaner chamber/s.
This probably is not the issue, but just letting you know that it could happen? Regards, Chris

I do the following when I replace a head gasket:
1. Check head for flatness 2. Check block for flatness 3. Replace all head bolts and studs-nuts. I perfer Kohler bolts-some use grade 8 bolts. 4. Decarbon head-top of block 5. Run a tap thru all threads that hold the bolts-studs in place 6. Torque head bolts-studs/nuts to Kohler specs in 3 increments. My torque wrench is set to 20, them 25 and them 30 foot pounds. 7. Torque the head bolts according to Kohler manual. 8. Run 15 to 30 minutes and retorque head bolts-nuts. Your Kohler should be good for a long time

Compression is: 140 dry, 160 wet. No internal engine noises after mowing and running it for 30 minutes.

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.
