Default Engine blown?
Hello, long time first time here. I bought a cub 1810 off craigslist 4 years ago for $325. Some kid had inherited it from his grandfather and didn't know what he had. It came with extra belts, all manuals, and even the receipts. I had a brutal hilly yard at the time and it worked great. The longer I've owned this mower, the more I appreciated the construction, look, engineering and usability.

Recently I moved to a new home with 1.8acres of grass...so I decided to do a complete service job on the old cub. New oil, plugs, filters, hydro fluid change and filter. Found a small leak in the oil filter line, got them replaced. ran some Lucas gas treatment through her.
Long story short on my fourth lap around the yard a heard a shudder and lost some power. Kicked off the mower headed to the garage. I got there and it's running funny and I look down and see oil under the mower, fairly large amount...I pulled the panel but not the black heat shield to look yet. (Afraid) am I in real trouble? Any chance it's not a blown up Kohler?

As an educated guess.........you have a broken connecting rod. You can tell by removing the spark plugs and rotating the engine. The broken rod will result in no pressure on the effected side when you put you finger over the spark plug hole.

I'll try it today. How would that explain the oil everywhere? I'm hoping the new oil line blew or leaked. How much pressure is on the oil system?

I had serviced it just before and had it full to the line. Haven't checked it, but know it's low since it blew out a half quart.

I didn't want to be the bearer of bad news, but Roland is probably correct. The oil is more than likely coming from the hole in the block that the broken rod made. I asked about the oil level to make the it wasn't over full from a bad fuel pump.

When it's cold, has SAE-30 in it, and WOT .......60 PSI at tops. When hot and running, no lower than 20 PSI.

There is no use of "sugar coating" it or being PC.

I couldn't find the hole, but I olny took the passenger side heat shield off. I see what looks like a small crack but can't be sure.

Really frustrating because I just spent a bunch of money and time tuning it up. Guess it was more than her old heart could handle!
Is 1811 a big upgrade?
Any opinions on new cub zero turns?

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.
