Craftsman 20 Hp 42" Deck Lawn Tractor - Answered Questions & Fixed issues

safety switch,probably seat.

Question moved from Cars and Trucks to one of the Lawn Tractor categories. That has all the indications of a battery that has reduced voltage and no cold cranking amps. There is just enough power to light the LEDS and make the relay click. Remove the battery and charge it up. Clean the terminals and connectors with a wire brush and smear them with Vaseline. Reconnect then full charged. Videos https://www.google.com/search?q=countax+a318ho+lawn+tractor+no+power ..

I would take the bowl off the bottom of the carb.. Probably you have clogged up holes that let the gas into the bowl.Or either the needle is stuck up not allowing the gas to flow...That's why pouring gas in carbs would let it run for s few seconds....Also try fresh gas..Gas doesn't have led in it anymore..It don't last year from year...After grass season is over..Buy some from Lowe's or home depot..Pour it into your tank and let the motor run to get it done into the carburetor...Then the next year it will start

Go to Sears parts.com and i trhink you can download a manual hopew that helps

go to sears parts .com and look up your model and the will give you a parts list and you can check if you have the right part they also have on line and phone help on any of their modfels.

If you had included model no. I could have been more help but you probably will have to replace drive plate and or more in transmission. If you go to searspartsdirect.com and in model number type in, hopefully you will get parts breakdown of the transmission showing parts.

sounds like the spindel bearings going bad next time feel spindles for heat ounds like one or more are bad need to be replaced.

Is the mower blades engaged if so check spindels if not check the transmisson but check all pulleys first

follow the manual for repairs

it could be a fuw things doing this,,,
check that the engine is charging the battery up when its running,,use a volt meeter across the battery it should show 13.5 volts if its charging up ok,,,,

then check that the voltage regulator is not draining the battery when the engine is not running,,,

fully recharge the battery first then check that it holds this charge,, take off the battery lead and leave the mower for a week or so if the battery has gone flat then you need a new battery!! winter time kills off batterys if there not kept on trickel charge,,,
there's a tip,,,,buy a solar charger,,,and hook it to the battery when your not using the mower,,it will keep the battery toped up for free???

Did you check the battery ?

Then its probably not the switch. No idea which mower you're talking about but most of them have several cut off switches. If the one under the seat is not working (ie it thinks there's no one sitting on it) then when you let the brake off it will shut off the engine. The same goes for the blade engagement switch. If you're lucky the same switch will be used everywhere so you can use your new switch to check each one in turn. Good luck.

it covers the hole on the deck

One or more of the spark plugs is not firing, allowing raw fuel to go through the system.

Use a tiny funnel and a rubber hose to reach the fill point easily

RRRRRRRRR you going to get a nother transmission because you need one or have that one worked on
