CLAAS Filters Guide

CLAAS at a Glance

CLAAS is a family-owned German agricultural machinery manufacturer founded in 1913 and headquartered in Harsewinkel, Germany. It is one of the world's leading makers of combine harvesters and forage harvesters, and also builds tractors, balers, and telehandlers. CLAAS machines are widely used in Europe, Eastern Europe, Russia, Latin America, and Australia, and the brand is especially associated with grain and forage harvest work, which places heavy demands on air, fuel, and hydraulic filters.

Main CLAAS Machine Families

CLAAS Arion. The mid-range tractor line, including the Arion 500 and 600 series, used for general farm work, forage, and loader tasks.

CLAAS Axion. High-horsepower tractors, such as the Axion 800 and 900 series, for heavy tillage and large farms.

CLAAS Xerion. A distinctive articulated tractor for very heavy field work.

CLAAS Lexion and Trion combines. Large and mid-size combines, among the best-known machines in the grain harvest. Lexion 700 series machines appear in many filter application lists.

CLAAS Jaguar forage harvesters. Self-propelled forage harvesters with very high engine loads and heavy air filtration needs in dusty crops.

CLAAS Scorpion telehandlers. Telehandlers used on farms for loading, feeding, and material handling.

Common CLAAS Filter Part Numbers

CLAAS publishes its own numbering, and many filters are made by suppliers such as Mann, Hengst, and Fleetguard. The references below are those commonly listed in aftermarket catalogs.

CLAAS machines use engines from several suppliers, and the same model name can have different filters depending on engine and serial number. Always confirm before ordering.

CLAAS Filter Maintenance Guide

Engine oil filters. Replace the oil filter with every engine oil change. Combines and forage harvesters run at high load for long hours during harvest, so oil filter quality matters.

Fuel filters. Replace fuel filters on schedule and drain water from the separator regularly. A fuel filter that clogs in the middle of harvest costs far more in lost time than the filter itself.

Air filters. Harvest dust loads the engine air filter faster than almost any other condition. Check the restriction indicator daily during harvest, replace the primary element when required, and keep spare elements on the machine.

Hydraulic filters. Replace hydraulic filters on schedule. CMATIC and HEXASHIFT transmissions and the working hydraulics rely on clean fluid for smooth operation.

Pre-season service. Replace the full filter set before harvest begins, not during it. Harvest is when machine downtime costs the most.

Service intervals are set by the machine manufacturer and depend on the model, engine, oil specification, fuel quality, and working conditions. Always follow the maintenance schedule in the operator's manual for your specific machine.

How to Choose the Right Replacement Filter for a CLAAS

• Use the exact machine model and serial number, since filters change between engine stages and model years.
• Match the CLAAS part number, then confirm dimensions, thread, and seals.
• Check that the replacement meets the original efficiency and flow specification, particularly for hydraulic filters.
• Stock a full filter set per machine before the season begins.
