My sons john deere tractor won't go in low gear or reverse only goes in high gear and the rear wheels seem to have trouble getting traction in the grass

For the traction problem I used 3M grip pad from the local auto store. The type used for foot traction on equipment. Cut strip and only applied them to the lugs 1/4" back from center. This keeps the sidewalk from tearing them off. They help the traction, but shouldn't give enough grip to wreck the gear box. I put an interlock on my grandsons tractor so he can't go from forward to reverse without removing power from the motor.
I had the same problem and replaced the shifter which I found at http://www.mypegperegoparts.com/switches.html. This fixed all the speeds and now it runs great. Hope this helps
