1, use low-voltage (12V) DC first.

2. Single-wire system, that is, the positive electrode of electrical equipment is connected with wires, which is called live wire, and the negative electrode is connected with the metal part of the frame with wires, which is called ground wire. However, between the generator and the voltage regulator, two-wire electric horn is still used to improve its sensitivity. 3. The negative electrode is grounded, and the grounding polarity of all electrical equipment of the same tractor is the same.

4, power supply equipment (battery, generator) and electrical equipment in parallel.

5. The whole vehicle circuit consists of several relatively independent branches, including power supply circuit, starting circuit, lighting and signal circuit, instrument and display circuit and auxiliary device circuit.

Precautions for installation:

1, blade installation There is no special requirement for the installation of chisel. The straight hook-shaped chisel has strong ability to enter the soil, poor soil throwing performance, easy to rent and entangle grass, and is suitable for soil with few weeds and hardening. Its installation is generally evenly arranged on the knife edge according to the spiral line and fixed on the knife seat with screws.

2. Adjust the rotary cultivator matched with the wheeled tractor, and the tillage depth is controlled by the hydraulic system of the tractor. Integral and semi-separated hydraulic systems should use position adjustment. The split hydraulic system uses the positioning clamp on the piston rod of the oil cylinder to adjust the farming depth, and the operating handle is placed in the "floating" position when working.
