1. Improved stability

Larger front wheels: The front wheels are responsible for carrying the weight during loading and unloading. Larger front wheels increase stability and prevent the machine from tipping over under heavy loads.

Smaller rear wheels: The rear wheels are mainly used for steering and support, smaller rear wheels help to improve flexibility.

2. Increased traction

Larger front wheels: Larger front wheels increase the contact area with the ground and improve traction, especially when working on soft or uneven ground.

Smaller rear wheels: Smaller rear wheels reduce rolling resistance and allow for more agile steering.

3. Optimized steering performance

Smaller rear wheels: Smaller rear wheels allow for more agile steering, making it suitable for work in confined spaces.

Larger front wheels: Larger front wheels provide better support when steering and prevent side slip.

4. Adaptability to different terrains

Larger front wheels: Larger front wheels can better cope with uneven ground and reduce bumps.

Smaller rear wheels: Smaller rear wheels provide more maneuverability on flat surfaces.

5. Balanced weight distribution

Larger front wheels: Larger front wheels distribute the weight of the load better and reduce the pressure on the ground.

Smaller rear wheels: Smaller rear wheels help to balance the overall weight distribution and prevent overweight in the rear.
