Replaced spindles on my mower and went to crank it up after it sat a few weeks and the starter made this loud grinding noise, pulled the cover off and looked at the starter and its spinning but its not rising up and grabbing the flywheel, but after turning the key a couple times it blew the 20 amp fuse, so i replaced the fuse and it blew again as soon as i went to try to crank up the mower to see if i could fix the starter from not engaging properly, went through 3 fuses before I gave up, is the starter making the fuse blow? Do i just need to replace my starter? Or is it something else. This just doesnt make sense to me, any help is greatly appreciated.
