The operation of a ground cotton picker (commonly referred to as a cotton harvester) must strictly adhere to regulations to ensure efficiency and safety. The following guidelines combine common operational procedures and key considerations for reference.
Pre-operation preparation

Personnel training and inspection

: Operators must undergo technical training and hold valid certifications before working. Inspect the field for obstacles before operation, remove residual plastic film, and ensure components like the cotton box and picking heads are in proper condition.

Equipment adjustment

: Adjust the seat and rearview mirror to suitable positions, inspect tires, hydraulic systems, and fire extinguishers. Before starting, raise the picking head to its highest position and lock it, disengage the parking brake.

Starting and driving operation

The operation method of the gourd melon harvester usually includes pre-start preparation, operation steps, and post-operation maintenance. The following explains the operation process based on common machine types.
Pre-start preparation
Check power supply and connections: Ensure the machine is connected to a reliable power source, inspect the power cord for normal operation, and confirm sufficient fuel and hydraulic oil levels for self-propelled models.
Clean the work platform: Remove moisture and dirt from the melon surface, ensure stable placement on the work platform to prevent rolling or sliding.
Adjust parameters: Set rotation speed, clamping force, cutting angle, etc., via the control panel according to melon size and type. For large harvesters, also check pickup width and cleaning device settings.

The operation of corn harvesters must adhere to strict operational protocols to ensure work safety, minimize losses, and extend the machinery's lifespan. The following precautions cover key aspects such as pre-operation preparation, trial operation, field operation, and special condition handling.

1. Pre-Operation Preparation and Inspection

Before operation, conduct a comprehensive inspection, including verifying fuel, engine oil, lubricating oil, and coolant levels.

Check the tension of V-belts and chains, ensuring no tools or debris remain on working components, and confirm all protective covers are securely fastened.

Inspect the installation status of bearings and high-speed rotating parts (e.g., stalk chopping devices), as well as the free travel of clutches and brake pedals.

Additionally, assess field conditions, level ditches and ridges, mark obstacles, and drain standing water to ensure operational safety.

The Chunming brand 4YMK series self-propelled flax thresher is an agricultural machinery equipment specifically designed for the threshing (rolling) process of flax crops after sun drying. Its core functions include automatic picking, continuous conveying, precise threshing, and aligned bale dropping of flax straw, while featuring self-propelled power and a highly adaptable structure. It effectively reduces labor intensity and meets the requirements for large-scale flax planting and mechanized harvesting (rolling).

The Chunming brand 4YMF series self-propelled flax turning and drying machine is an agricultural machinery equipment specifically designed for the post-harvest turning and drying process of flax crops. It integrates functions such as self-propelled movement and flax turning operations into one unit, enabling efficient and uniform turning and drying treatment of flax. This accelerates the drying speed of flax, improves flax quality, reduces labor intensity, and is suitable for large-scale flax growers and agricultural cooperatives in post-harvest flax processing operations.

The Chunming brand 4YMB series self-propelled hemp harvester is a mechanized harvesting equipment specifically designed for hemp crops. It is suitable for harvesting mature hemp and ramie, evenly laying the hemp stalks in the field for natural degumming (i.e., dew retting method: its core principle involves natural microbial fermentation to decompose the gum), thereby achieving effective separation of hemp fibers from the woody core.

4YW-2 series corn harvester is a traction type corn harvester, with six models available, namely A, B, D, E, F and G. It can complete the operations of picking ears, peeling (except D and G models), loading and crushing stalks and returning them to the field (recycling) at one time, and is a good machine to solve the problems of mechanization of corn harvesting process and crushing stalks and returning them to the field (recycling).

During the busy farming season when the corn thresher is not in use, the following aspects should be noted during its normal parking and storage: First, before parking and storing the corn thresher, the operator should conduct a comprehensive "physical examination" of the agricultural machinery, that is, maintenance of the agricultural machinery to keep it in good technical condition.

With the modernization of rural machinery, corn thresher is becoming more and more popular as a helper for farmers. But hereby remind you to pay attention to the following matters when using the fully automatic corn thresher: 1. Since the working environment of the thresher is very bad, the personnel participating in the operation should be educated on safe operation in advance so that they understand the operating procedures and safety common sense, such as tying sleeves tightly, wearing masks and protective glasses, etc.

Good news for Qixian folks! No more manual garlic harvesting!
