Likely the seat switch. It doesn't see an operator in the seat but can be reverse swirch or PTO switch or a short to frame. It requires further troubleshooting to determine exact cause.

Contact Jack's Small Engines and see if they have wiring diagrams for the two engines? The pin-outs must be different. https://www.jackssmallengines.com/jacks-parts-lookup/manufacturer/briggs-stratton/briggs-stratton-engine/200000-399999-series/31p600-to-31p699/31p677-1373-b2 ..

Question edited for full 'make model (what it is)'. Question moved from Cars and Trucks to Garden Tractor. 'Cranking' is the engine turning. So it doesn't even turn, just 'tries' to turn? Check battery for voltage and CCA (cold cranking amps). Or the engine cranks, fires and runs, you engage drive and it stops? Best guess for that is strip and clean the carburetor.

Probably something wrong with the mount. You have a photo?

Issue is in the primer block on carb. may be plugged. On diaphragm side needle may be stuck. You have to take the carb apart and clean it, or possibly replace the metering & diaphragm membranes. Kit is about $8, and how to do it is on many youtube videos. Have fun.

The serial number should give you that information. It is located on the frame under the seat or on the underside of the seat itself. If it is the Kohler engine there will also be a serial number sticker on the upper right side of the engine. These numbers should help identify the model you have. These can also help when you need to order parts.

Likely it is only running on one cylinder.

personally I would replace the belt, it operated in a dirty area. belts also have a life.

Any gasoline engine needs 3 things to run. Fuel, Air and Spark. Open the cover on the air filter box and inspect the condition of the actual filter. It should be clean and not wrapped in plastic. Yes, It does happen! Look in the hole the filter covers to check theres no dirt it there. Refit the filter. Remove the spark plug but push it back into the plug lead. Using a pair of insulated grips hold the sparking end against the metal on the engine block. Get a helper to pull the start cord 3 or 4 times and watch the plug. Your looking for a nice bright blue spark across the gap on the plug. If you are in any doubt replace the plug anyway with a decent brand name. Next get as close to the open plug hole as you can and sniff. Can you smell gasoline? Refit the spark plug. Take a close look at the fuel tank and find the pipe supplying fuel to the carburettor. at the tank end is there a small twist valve mounted on the tank that the fuel pipe comes off? This is called a 'Petcock'. It is a fuel shut off valve for long term storage. If there is one there take a close look at it and it should be marked as 'ON', 'OFF' and 'RES'. There should be an arrow on the lever but it is often too small to see clearly. Twist it so the short end of the lever is pointing at the ON position. If none of these checks help you may need to return the unit to the store you bought it from as it might just simply be a faulty example.

Safety circuitry is detecting a no operator in seat. Test the operation of the seat switch.

There are a few ways. You can ask the maker. You can search the model and then Google Reviews and the date of the reviews. Google the manual and at the bottom look for an printing date. Sometimes the serial number is coded. Say 0500198, is the 198th one made in 2005.

Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also. When you are trying to process too much grass/leaves they could pack up under your deck and push off your belt.
