2008 Sportsman 300 clutch knowledge

I was given a 2008 Polaris Sportsman 300 by the original owner. He is one of those people that was given a lot of money and respects nothing, and his kids are following right behind him. So, his kids pull the 300 up to a tree and proceed to cook the clutch until it could no longer move. Then they did the same to a John Deer 4×4. Nice kids, huh? They left it there for a year. Another kid pulled some parts off when he was told he could have it. He lost interest and along comes me another year later.

I feel sorry for it and decided to bring it back. I have it running just fine, but it won’t move because things are gone. I have never owned a 4×4 4stroke ATV. I had a couple of 250R’s, a Suzuki Quadzilla, and a Yamaha Blaster. All 2 strokes with full transmissions, so I have no idea what this needs or is missing. I have rebuilt cars and bikes, so I can probably do it but I don’t really know where I am beginning, considering the stuff that’s missing.

Is there someone willing to look at some pictures and can help me determine what is missing and needs to be replaced? Thanks for your time.
