3ZT Series Double Spring Cultivator

Updated: 2026-08-06

Overview

The 3ZT Series Double Spring Cultivator is a specialized agricultural tool designed to enhance soil preparation and weed management. Its dual spring mechanism allows the tines to absorb shocks and maintain consistent soil penetration, even in uneven terrain. This cultivator is particularly favored for its versatility, serving row-crop farms, orchards, and vineyards with equal efficacy. The robust construction ensures longevity, while the adjustable depth settings cater to varying soil conditions. Farmers appreciate its ability to minimize soil compaction while maximizing aeration and moisture retention, making it a staple in modern precision agriculture.

Structure and Working Principle

The cultivator’s frame is built from reinforced steel, providing stability and resistance to bending under heavy loads. The tines, made of high-carbon steel, are mounted on double springs that flex upon encountering obstacles, reducing the risk of damage and ensuring continuous operation. When attached to a tractor, the cultivator’s tines rotate or oscillate to break up soil clumps and uproot weeds. The spring mechanism dynamically adjusts the tine pressure, allowing for uniform cultivation across varying soil densities. This design minimizes power requirements while maximizing efficiency, making it suitable for use with mid-range tractors.

Key Features

The 3ZT Series stands out for its dual spring system, which not only enhances durability but also reduces wear and tear on both the implement and the tractor. The tines are replaceable, lowering long-term maintenance costs. Adjustable depth settings (typically 10–30 cm) allow farmers to tailor the tool to specific crops or soil conditions. Another notable feature is its modular design, enabling attachments like rear-mounted rollers or additional tine sets. This adaptability makes it a cost-effective choice for farms with diverse cultivation needs. The cultivator’s wide working width (commonly 2–4 meters) ensures high coverage per pass, boosting productivity.

Application Areas

This cultivator is widely deployed in row-crop farming for crops like corn, soybeans, and cotton, where inter-row cultivation is critical. Its precision makes it equally effective in orchards and vineyards, where avoiding root damage is paramount. The spring mechanism excels in rocky or uneven soils, where rigid tines might fail. Beyond agriculture, the 3ZT Series is used in land reclamation projects and organic farming systems, where mechanical weed control replaces herbicides. Its ability to work at shallow depths also makes it suitable for seedbed preparation in horticulture.

Maintenance and Precautions

Regular maintenance is essential to prolong the cultivator’s lifespan. Inspect springs and tines before each use for signs of fatigue or cracking. Lubricate pivot points and bearings monthly to prevent rust and ensure smooth operation. Avoid using the implement in overly rocky or compacted soils, as this can accelerate wear. Store it under cover to protect against weather-related corrosion. For optimal performance, calibrate the depth settings according to soil moisture levels—deeper settings for dry soils and shallower for wet conditions.

B2B Procurement Guide

When sourcing the 3ZT Series, prioritize suppliers with a track record in agricultural machinery. Verify compatibility with your tractor’s horsepower (typically 50–100 HP) and hitch type. Request warranties covering at least the frame and springs, as these are high-stress components. Bulk purchases may qualify for discounts, especially during off-season periods. Consider after-sales support, including spare parts availability and local service networks. For reference, prices range from $1,500 for basic models to $3,500 for configurations with added features like hydraulic depth control.
