The post will not allow me to add to the responses for some reason.
This response is without malice intended. There are several elements of the post that deserve a better answer. The weight of the loaded spreader is dead weight spread to the four wheels at the very corners of the box. This is far different than the twisting and leverage forces applied by an engine and transmission system. The wooden sides of a honey wagon allow it to flex over uneven ground, twisting as the wheels encounter different levels. The wood is an integral component in the structure of most of them.
The differential is needed for driving the rear wheels of the unit you intend. If a differential is used for a belt pulley it will go twice as fast on the pulley side as when both wheels drive.
If a brake is used to "lock up" one side of the differential, and the other side is driving the wheels, the wheel side will move at twice the speed. (differential action)
Flat belt systems are just aligned crowned pulleys with a belt around them and a method of applying tension. The ratio is circumference to circumference of pulleys. The slower the belt speed in FPS the less hp can be transmitted.
A 3" belt can easily transfer 10 hp at normal tractor pulley speeds, on 7 to 10 inch pulleys.
There are design applications and power formulas in Machinery's Handbook.
In the context of the project you envision, it seems to me that a pre-constructed platform with integrated brakes would be the ticket to success.
You could put all the design features and effort into the body work, and leave the power train to a manufacturer. With respect, Jim
