I have a craftsman gt 5000 model 917.276220 runs fine but when mowing deck is engaged it wants to die when under a load or cutting tall grass, it will stay running but when i start to cut it bogs down?

How tall is the grass you're mowing?

Possibly it needs cleaned. Remove deck and clean out any build up if grass/dirt.

If the blades have been sharpened multiple times, replace. When the lateral length gets too short the blades no longer create enough lift to expel the clippings.

You have a bad switch a seat or clutch one of them are bad

deck is dented blade is hitting deck

If you are cutting to much grass this can happen or if the throttle control is not in fast speed (rabbit). If it is in slow speed (turtle) it will tend to die down in tall grass or wet grass. Good Luck...

check the deck belt tension, or slow down the mower may not be able to handle the load

you are cutting to much grass & it isn't kicking it out fast enough out of deck which will bog it down it might help if you clean out the bottom of the deck & also dont cut really low if grass is really tall also cutting wet grass will aslo cause the bogging if i can further help e-mail me wade at [email protected]

what is happening tom is the blades are cutting more than the deck can discharge (spit out) try changing the mowing deck to a higher setting & try that if that works then that is the problem also try cleaning out the top & botton of deck there could be alot of old grass caught under there causing some of it aslo if i can further help e-mail me wade at [email protected]

Most likely what you did was burn one or more spots on the belt. When the blades and belt stop turning, like in tall grass, the engine doesn't stop and will burn flat spots on the belt at the engine pulley. Every time the flat spot hits a pulley, it will jump and can set up a bad vibration. Run your hand around the sides of the belt or take it off and you will feel or see the thin spot(s) on it. Replace belt.

Depends on how it cuts off. If it gradually slows down over a few minutes or surges, it's likely the carburetor needs to be cleaned and rebuilt. But if it's an immediate cut off, it's likely to be a safety switch such as the one that shuts down the engine when you get off the seat if the mower is running. Sometimes this happens frequently to a light person who bounces on the seat when mowing.

Grass and debris clogg the switch mechinisms, safety interlocks are sometimes a pain to diagnose but I would first look at the seat interlock, the petal switch and ffinally then the mowing deck.
