Toy John Deere Gator electric one will not go forward only reverse Do we need to purchashe new motor for it?

Electric toy Jonh Deere Gator will not shift into forward stays only in reverse. Do we need to purchase a new motor for the toy or is it fixable?|||The same motor drives it forward as backward so it's probably not the motor. More likely it's the switch. The forward contacts (it'll be double pole, double throw) aren't working.
