When buying a used trailer, the condition, payload, braking system and tires play a decisive role. Pay attention to a stable frame, intact hydraulics and functioning lighting. The hydraulic cylinders and drop sides of tipper trailers in particular should be checked. Many dealers offer inspected used models that are ready for immediate use - compare the offers and find the right model for your farm.
Frequently asked questions about used agricultural trailers
What towing capacity is a tractor allowed to tow?
The permissible towing capacity of a tractor depends on its own weight, engine power and braking system. As a general rule, unbraked trailers may generally weigh up to 3.5 tons, while braked trailers can tow loads of 10 to 40 tons. Depending on the model, modern tractors with powerful braking systems can also pull even heavier trailers.
When is an air brake mandatory for trailers?
An air brake is mandatory for heavy trailers with a gross vehicle weight of around 8 tons or more. It ensures even distribution of the braking force and prevents uncontrolled braking. A powerful braking system is essential to ensure safety, especially in road traffic.
What licensing and legal regulations apply to trailers?
Agricultural trailers are subject to certain licensing regulations. In many countries, there are special regulations for speed, towing capacity and lighting. For example, agricultural trailers may often be driven without their own registration if they are used exclusively on the farm. Anyone driving a trailer on public roads must have a license and insurance, depending on the total weight.
What payload should an agricultural trailer have?
The payload depends primarily on the intended use. While smaller tippers carry 5-10 tons, large dump trucks and low-loaders can carry payloads of over 20 tons.
How often does an agricultural trailer need to be serviced?
Regular maintenance is important, especially for brakes, hydraulics and axles. An annual check helps to detect wear at an early stage and avoid major repairs.
What coupling systems are available for agricultural trailers?
The most common coupling systems are the drawbar eye coupling (for pin or jaw coupling), the K80 ball coupling (for more stability with heavy trailers) and the turntable coupling for more maneuverability.The choice of coupling depends on the combination of tractor and trailer as well as the permissible loads.
What influence do the tires have on the performance of a trailer?
The tires of an agricultural trailer influence traction, soil protection and handling. Wide low-pressure tires reduce soil compaction in the field, while narrow high-pressure tires are better suited for road transport. Attention should also be paid to the tread pattern - studded tires offer better grip on unpaved surfaces, while road tires minimize rolling resistance.
What role does the suspension play on agricultural trailers?
The suspension ensures better load distribution and greater driving comfort. Common systems are leaf suspension, which is robust and cost-effective, and hydropneumatic suspension, which automatically adapts to the load and ensures a smooth ride. Good suspension reduces vibrations and protects the load and vehicle.
