Husqvarna rz5424 cuts off after about 1 minute of cutting grass - good battery (14v when motor running) only happens after engaging blades

SOURCE: I have a Husqvarna 23hp 48

not sure but is battery being charged the right way have seen battery's put in and charged backwards

SOURCE: Husqvarna YTH20K46

Is this the first time cutting grass with a lawn tractor?
How tall of grass?
Use the grass cutting heigth adjustments on the tractor to a higher setting when cutting tall grass. Cut again to a lower height setting on the second pass. Grass higher than your tractor is not good for your tractor. Follow the manual instructions for best results.

SOURCE: blowing fuses

try unplugging the pto, starting the mower and then engaging the blades. If it still blows a fuse the problem lies in the mowers wiring. If not the problem is the pto. Hope this helps

SOURCE: I have a Husqvarna Yth 180, the lawn mower shut

try unplugging the pto then start the mower next engage the blades and see if the fuse blows if it does the problem lies in the mowers wiring if not the problem lies in the pto. hope this helps

SOURCE: Mower Runs briefly then cuts out and wont restart.

These ride-ons have a cut out solinoid under the carby that when there is no power or the ign is cut it will drive a little pin into the main jet to prevent flooding, id say this is why your mower runs for 20 and stops...

There is a few reasons this could be occuring:

#1First I would be checking the battery see if its dropped a cell or has a dead cell, you can do this by load testing it with a load tester or removing it and taking it into a battery specialist. if this is the case the battery will not accept a charge from the charging circuit...

#2 Check your wiring with a multimeter from the armature under the flywheel all the way back to your battery (also these models may have a regulator/rectifier that can be tested they have test values and can be checked by your local small engine repaier)

#3 If all your wiring is ok then you will have a problem with your armature this is located under the flywheel on your engine it has two seperate windings one for the charging of your battery and the other powers your headlights / elec magnetic clutch, the one for the charging will be unservicable these can be diffucult to access and test and is probably best done at your local small engine repair shop...

Hope this helps you out

Kind Regards
