The Columbus is a self-propelled straw walker combine harvester from Claas . It is located below the Claas Europa and was built from 1958 to 1970. It was aimed primarily at small businesses. A total of more than 60,000 Europa and Columbus combine harvesters were built in Harsewinkel. The replacement of the Columbus took place in 1968 by the Claas Comet .

The Columbus is a self-propelled straw walker combine with a 1,800 mm wide header. The height of the cutting unit is hydraulically adjustable and is equipped with twelve crop lifters. It adapts to uneven ground using springs. The height of the pick-up type reel with spring tines is hydraulically adjustable, the speed is fixed and cannot be adjusted. The reel, knife and intake auger can be switched on and off independently of the threshing mechanism. The cutter is for the mowing of bearing fruit suitable. A corn picker for the Columbus was also available on request.

The threshing drum has a width of 800 mm and a diameter of 450 mm, it has six beater bars. The speed can be set between 620 min −1 and 1,380 min −1 by changing the gear ratio using change gears . The concave with torque adjustment has eight basket rails and a de-awning device, which can be activated to increase the number of basket rails to 11. The concave also has a stone trap. The Columbus has three rack shakers.

For cleaning, the Columbus has a barrel blower that blows over a lamellar sieve that can be adjusted for different types of fruit. The four lower sieves can be exchanged for different types of fruit. The grain is transported by the grain auger to the elevator, which is placed in front of the left rear tire. The elevator conveys the grain to the sorting cylinder on the roof of the thresher, which has four exchangeable sieves and sorts the grain into three quality levels. On the left side of the thresher there is a standard bagging stand with bagging device , from which the bags can either be loaded onto a trailer or placed in the field. As an alternative to the bagging stand, there is a unloading screw that can unload the grain directly into a trailer. A grain tank is optional for both the bagging stand and the unloading auger.

The Columbus deposits the straw in swaths as standard; a straw press or a straw chopper were optionally available for an additional charge.

With the Columbus, only the front wheels are driven. It has a three-speed transmission with an additional reverse gear, to which the power from the engine is transmitted via a single-disk dry clutch. The speed can be continuously adjusted hydraulically in the individual gears. Four different engines were available for the Columbus, two petrol and two diesel engines. Initially, only the air-cooled 1.2-liter Otto boxer engine VW Type 122 with 27 HP (approx. 20 kW) was offered, the output of which was increased to 29 HP (approx. 21 kW) in the course of production. Later, the air-cooled 1.6-liter boxer engine VW Type 126 with 38 hp (approx. 28 kW) was also offered as the most powerful unit. The water-cooled diesel engines, each with a displacement of 1.8 liters, both produce 34 hp (approx. 25 kW). These are the engines OM 636 from Daimler-Benz and A4.107 from Perkins. The engine is mounted on the Columbus to the right of the driver's cab.
