Just bought an argo

Problem One : When i put my 1999 Argo Conquest 8x8 in reverse only it makes a noise like a car when i don't push in the clutch. Its like there is no clutch to put it into reverse , you have to put it in reverse really fast to stop it from that grinding sound.

Problem Two : when i try and start the argo, the starter turns for a short time and the starter makes that free spining noise . i have to keep clicking the key untill the starter grabs , then it turns the motor for a very short time and free spins like its turning nothing , then i keep turning the key and it spins the starter . i keep doing this untill it catches and then it starts all over again.

Who can anwser my questions ?
