[ChristianFitz]

Tractor driver's licenses are categorized into the following models: 1. Medium-sized tractors (with an engine power exceeding 14.7 kilowatts), the license code for permitted operation is "G". 2. Small steering wheel tractors (with an engine power below 14.7 kilowatts), the license code for permitted operation is "H". 3. Hand tractors, the license code for permitted operation is "K". Here are some additional details: Precautions for operating a tractor include: 1. Parking location: It is best to park in a garage, but avoid storing it with fertilizers or pesticides to prevent corrosion from volatile substances. If parking outdoors, choose a well-ventilated area on higher ground and cover it with plastic sheets or other protective materials to prevent mechanical damage and rust. 2. Supporting the chassis: Elevate the tractor using wooden blocks or bricks to reduce the load on the tires. If the chassis is not supported, the tires should be inflated 10%—20% more than usual, and regular checks and inflation are necessary to avoid underinflation.
