Depends on torque/speed rating of motor, what the gearbox ratio is, how fast you want to push it, is the load on wheels/rails/nothing,
uphill/downhill?

its needs to go at about 3 mph and it will be free running until it pushs the load and its all on flat ground.

Need to know rated speed of motor and gearbox ratio. At a guess though - if you wanna push 4 tonnes with an 800 W motor - i'd say you want the
smallest damn sprocket you can get on there!

Put a torque wrench on the hub nut of the wheel (if you can) and see how much the turn over torque is to move the 4 tonne load.
If you know the starting torque of the motor you could work out the sprocket sizes based on torque ratios.
