It starts up, but the engine dies when I leave the clutch out. It seems to happen everytime it sits for a while. Last time, I just fiddled with it until it worked. I have no clue what made it go. Any help?

I wonder if the driver presence switch under the seat is the cause of the problem. I believe that you can unplug it and it will be disabled. Give it a try. You will have to put a "jumper" wire into the plug. If the tractor keeps running when you let out the clutch it is likely the switch is bad. Remember, when you disable the seat switch the mower will continue to run even when your butt leaves the seat. This is a safety issue and should be done just to check the switch.

Perhaps it's the choke mechanism. If it idles ok, but then when it goes under load (into any gear other than neutral) it's "too much" for the engine if it hasn't come to temperature with a choke stuck open (making a normal air-gasoline mixture rather than a rich mixture for startup). Or, the choke may be sticking closed, which would starve the engine for oxygen when under load. Try letting it warm up a little bit (or a little bit longer), also make certain the blade isn't engaged when you just go to move it (if you can disengage the blade) because that puts more "load" on the engine. If the exhaust seems black then I'd vote for a choke stuck closed. You can refer to the owners manual to help find the choke and make certain it seems to work freely (remove debris and make sure everything seems lubricated (WD-40 works well)).

First of all, never unplug a safety switch, whether it is under the seat or anywhere else.
Two things are possible as your source of the problem. One is that the throttle and choke are not opening fully and the other is that there is something in the drive line that is binding.
With the engine off and spark plug disconnected and grounded, check the drive belt and pulleys for any binding. If all is freely moving, the problem is likely in the carburetor. Also make sure the air cleaner element is clean.
But NEVER disconnect safety devices or attempt to bypass them. If you suspect they are faulty take the machine to a qualified technician for diagnosis and repair.

Something is locking up. Transmission? Belt not turning? As long as the clutch is in the engine is ok? Letting the cluth out puts the work load on the engine. If something is locked up, it puts strong enough load on the engine to pull it down and stop it. It needs to be checked by a small engine repair shop.

Is it left outside uncovered? What happens when they sit for long periods of time is the steel pulleys tend to rust, and the belts tend to stick to the pulleys. Look underneath and make sure everything will turn before moving the tractor ( put trans in neutral and rotate belt by hand, make sure no idler pulleys/ other parts are stuck. If they are , then they need to be lubricated.

sounds like a safety switch, either the seat witch or or clutch switch, more then likely the clutch switch Go onto sears.com and look up your model number and it will give you a diagram of where the switches are and part numbers to get a new one. They are very easy to replace once you get to it.
