Fourtrax 4X4 driveline engaged

Have a 1993 Fourtrax TRX300F, brakes are not engaged but can’t move the ATV. Both front and rear axles move just a little bit, I can engage the rear brake and axles do not move.
I can turn over the engine without the wheels moving.
What is the problem? Any and all imput would be appreciated.
Tom
