How to Choose an Excavator for Farmland Capital Construction? Key Parameters and Operating Points Explained
In farmland capital construction, the excavator can be considered a "jack of all trades": digging irrigation and drainage ditches, desilting and enlarging ponds, levelling land, building tractor roads, digging tree pits - none of these can be done without it. When purchasing or renting, many farmers are often baffled by a long list of models and parameters. In fact, as long as you grasp a few key indicators, you can pick the model that suits your own plot.
Understanding these key parameters
The first is bucket capacity, which determines how much soil can be dug in a single pass and directly affects working efficiency; the second is the overall machine mass and engine power - the greater the mass and the more ample the power, the more force there is for digging hard soil and breaking up compacted layers, but the pressure on field roads and bridges and culverts must also be considered; the third is the maximum digging depth and digging radius - these two figures are especially important when digging deep ditches and clearing deep ponds; the fourth is the travelling method - tracked machines have a large ground contact area and press lightly on the ground, making them suitable for soft paddy fields and wetlands, while wheeled machines have good mobility and move quickly between sites, making them suitable for areas with more paved roads. In addition, the quality of the hydraulic system determines whether the movements are smooth and powerful; veteran operators often say that "hydraulics are the lifeblood of an excavator", and this deserves extra attention when choosing second-hand equipment. It should be noted that the detailed parameters of each specific model should be based on the manufacturer's nameplate and manual, and you should not rely only on verbal promises from sales staff.
Practical advice for purchasing and operating
When purchasing, first be clear about the purpose: for scattered small plots and work around greenhouses, a small machine is more flexible; for contiguous high-standard farmland construction, a medium-to-large machine is more efficient. At the same time, focus on examining after-sales outlets and parts supply - if the machine "breaks down" during the busy farming season, waiting a week for parts will delay important work. For buying agricultural machinery, pay attention to the agricultural machinery purchase subsidy policy; the scope and standards of subsidies vary from place to place, and the specific information published by the local agricultural machinery competent department shall prevail.
There are also finer points in the operating stage: before starting work, walk around the machine and check the engine oil, hydraulic oil, coolant and track tension; before operating, first find out whether there are hidden pipes or cables underground, to avoid digging them up and causing losses and danger; in rain and after rain the soil is wet and soft, and tracks easily sink, so movements should be slowed and sharp turns avoided; when working beside ditches and ponds, keep a sufficient safety distance to prevent collapse. Operators should be trained and familiar with the machine before taking up the job, and beginners must never rush and work recklessly.
In short, choosing an excavator is not about the bigger the better, but about "choosing the machine according to the land and according to the job". Understand the parameters clearly, think through the purpose clearly, and add standardised daily maintenance, and a suitable excavator can save a great deal of manpower in farmland capital construction, helping you prepare the land quickly and well.
