Tractor keeps blowing a fuse

Kelly, ray g. nailed it, First be sure it is only to be a 20 amp fuse, The wires to the clutch that drive the deck will be broke or bare shorting out on each other or on metal, wire are quite commonly broke by the clutch plug or close by. what you can do is carefully follow the wire from switch through the system and look for damage or bare spots, pay special attention when wire runs through frame/body holes and any where it could rub on metal or moving parts. Check the attached links,instruction and guides,4th link see Randy T. reply in forum, has good test method for your problem. Good Luck.

Yes theclutch is an electromagnet and basicaly a big bundle of wires. If you have a multi-meter or just an ohm meter you can check the resistance of of the coil by simply touching the 2 prongs coming from the coil with the meter. The resistance should be something low like 1000 ohms or 1k or less. Some common sence should be used if you dont have the specs. If it shows less than 1 ohm than you most likely have a short. If it shows alot more like 1M or more there is an open and either way the clutch will need to be replaced.

That won't help, and is never recommended-will only cause further problems down the road. It sounds like the plug is bad and needs replaced, if you can use it and it blows the fuse. They do go bad occasionally.

could be the safety switch for the pedal

The breaker is too small, the cord is too small, the starter motor on that thing draws 18 amps. It will trip any 15 amp breaker and any 20 amp breaker with something else running, any cord will drop the amp below the starter winding min. make sure nothing is running, separate circuit if you can find one, no extension cord, and a 20 amp breaker in the fuse box. if that is not the problem , then something is shorting out when you hit the switch. Check the wiring on the pump and make sure all is secure, no loose wires, no sparks. My compressor won't run on any old plug, has to be 20 amp, has to be without a cord or with a heavy cord, and has to be hot out, if it is cold, forget it!. We have to keep the compressors in a heated room so they will run in the winter. Hope this helps.

Have you replaced the blower resistor . some times they can cause the fuse to blow . You may need a muiltmeter to test the current draw on the blower motor circuit. the draw should be less then half of the rated fuse .( 20 amp fues draw is less then 10 amps) You did not say but does the blower work on high only or the lower speeds with out blowing the fuse ? if it does work on low or high with out blowing the fuse i would replace the blower resistor

need to ohm out the clutch....clutch ohms are 2-4 ohms anything less will blow the fuse due to it being shorted out,,,,,takes less than a min to find out with a multi meter

hope this helps

ck the wires going to yhe head lites theay could be frad and shorting out

my mtd lawn mower wont start . when I turn the key there is a buzzing soung where the battery conectors are near the shifter but the starter is hot and getting juice
