Murray Select Riding Mower Not Starting

My trusty Murray riding mower will not start. When I tried to start it, it tried to kick over. I thought the battery might not be 100%, since I hadn’t cut the grass in a few weeks. I gave it a few more tries, before it made a grinding noise. I think I fried the starter, or the solenoid. The starter was hot to the touch afterwards, and I did try to jump it from both my truck, and a chargers. Power is there, just clicks. Any suggestions?
