Farm Tractor

A:A: The key factors are the operating scenario and the plot size. Refer to the following matching formula:
--Small plots (<50 mu)/greenhouses/orchards: Choose a compact tractor with 20-50 horsepower, flexible for narrow row spacing.

--Medium plots (50-200 mu)/conventional crops (wheat, corn): Choose a wheeled tractor with 50-100 horsepower, suitable for tillage, seeding, and hauling.

--Large plots (>200 mu)/heavy-duty operations (deep plowing, pulling large implements): Choose a tractor with 100 horsepower or higher, equipped with a high-pressure lift and a high-torque transmission.

--Special applications: For paddy fields, choose a tractor with specialized paddy field tires and a lightweight chassis. For hilly and sloping terrain, choose a tractor with four-wheel drive and a low center of gravity design.

A: For mid- and low-end models (<150 horsepower), choose domestic products. For high-end models (>150 horsepower), consider imported products:

Domestic products: High cost-effectiveness (30%-50% lower than imported products), easy access to parts, and a wide range of after-sales service outlets, making them suitable for general operations.

Imported products: High-end models (such as the John Deere 8R series) are durable (10-15% lower failure rate) and highly intelligent (standard centimeter-level navigation), making them suitable for large farms or high-value-added crops (such as organic vegetables).

A: First, check the hydraulic system:
Check the hydraulic oil: Is the oil level below the dipstick line? Is the oil cloudy? (Replace with new oil, using the manufacturer's specified type, such as Dongfanghong special hydraulic oil.)

Check the piping: Check for leaks or loose joints (tighten fittings or replace seals).

Check the lifter: Is the high-pressure lifter stuck? If it's stuck, lubricate the lift arm bearings. If the electronically controlled lifter is faulty, contact after-sales service for sensor calibration.

A: It's not recommended. A model specifically designed for paddy fields should be selected.

The key differences are:
Paddy field tractors: Lightweight chassis (anti-sinking), high ground clearance (over 350mm to prevent mud and water splashing), paddy field tires (wide tread with deep tread to prevent slipping), and a mud-proof and sealed front axle.

Dry farm tractors: Designed for heavy loads (heavy chassis and strong grip), tires feature a herringbone pattern. Directly entering paddy fields can easily cause the vehicle to sink and damage seals.

A: The most common cause is a clogged air/fuel system.

Follow these steps to troubleshoot:
First, check the air filter. If it's covered in dust or weeds, clean or replace it immediately (clogged filters can lead to insufficient air intake, incomplete fuel combustion, and black smoke).

Next, check the fuel system: Check the diesel filter for blockage (replace the filter) and the fuel for impurities (drain any sediment at the bottom of the tank).

Finally, check the load. If the implement is too heavy (e.g., a large rotary tiller with low horsepower), reduce the load by reducing the tilling depth or shifting to a lower gear.

If black smoke persists after these checks, contact after-sales service to check the fuel injectors (possibly due to poor atomization). Do not force the tractor.
