Detailed Explanation of the Parameters and Performance of the Wuzheng GA60 (4LZ-6) Wheat Harvester
The Wuzheng GA60 is a wheeled self-propelled grain combine harvester, model 4LZ-6, mainly used for wheat harvest; in many regions it can also handle rice harvest by adjusting or replacing some components. For those preparing to buy a machine, understanding its basic parameters and performance positioning first is more reliable than just listening to a sales pitch.
What the model number reveals: what 4LZ-6 means
Agricultural machinery model numbers are not assigned at random. "4LZ" follows the agricultural machinery product numbering rules: "4" stands for the harvesting machinery category, "L" indicates a grain combine harvester, and "Z" means self-propelled; the "6" after the dash represents the feed rate class, that is, the class of crop volume the machine threshes per second. The larger the feed rate, the bigger the machine's "appetite" per unit of time, and the larger the working scale it suits. Seeing 4LZ-6, you can roughly tell that this is a model with a medium-to-upper feed rate, suitable for work in large, contiguous wheat fields. As for the specific data such as cutting width, engine power, grain tank capacity and overall weight, please refer to the parameters published in the manufacturer's "Product Operation Manual" and the agricultural machinery purchase subsidy catalogue for the current year.
Structural composition and performance characteristics
As a wheeled grain combine harvester, its working process is the same as most similar models: the header cuts the wheat and feeds it in, it passes through the inclined conveyor trough into the threshing cylinder for threshing, the grain passes through the concave and is cleaned by the cleaning sieve together with the fan, the clean grain falls into the grain tank and is then loaded into a transport vehicle through the unloading auger; the straw and debris are discharged outside the machine or chopped and returned to the field. On dry fields and paved roads, the wheeled chassis moves noticeably faster than crawler models, making it suitable for cross-region operations and road transport, which is also why users in the main wheat-producing areas of the north prefer wheeled machines. However, the passability of wheeled models in wet, soft fields is reduced, so extra care is needed when harvesting rice or rushing the harvest on rainy days.
Working efficiency and routine maintenance
Actual working efficiency is affected by many factors: crop maturity and moisture content, yield per mu, field size and levelness, stubble height, and the operator's skill level all make the daily harvested area vary considerably, so do not focus only on theoretical data. In daily use, it is recommended to clean tangled grass and debris from the header, cylinder and cleaning parts before and after each shift, check the tension of belts and chains and the wear of wearing parts, and lubricate regularly as required by the manual; after the harvest season ends, clean thoroughly, drain the fuel and cooling water, store it in a dry, ventilated warehouse, and carry out a full inspection and test run before the harvest begins the following year.
Finally, a reminder: the standards, catalogues and application procedures for agricultural machinery purchase subsidies differ from place to place, and the specific subsidy amount is subject to the policy published by the local agricultural machinery authority for the current year. When buying a machine, it is advisable to use formal channels, ask for an invoice and "three guarantees" certificate, and understand the distribution of after-sales service outlets, so that using it is more worry-free.
