The Kverneland 4332LR - 4336LR - 4336CR is a towed swather designed for the swath laying of common grass and corn crops. The LR model operates on the right-hand side of the tractor, while the CR model can operate on both sides. The machine is towed by a drawbar coupled to the tractor's lift arms, which allows it to be set in either transport or working position using the tractor's hydraulic system. The cutting unit is hydraulically connected to the main frame and can be lowered using the tractor's hydraulic system. It is balanced by strong springs, ensuring precise ground following and uniform crop cutting. For safety, the recommended mowing speed does not exceed 15 km/h (9 mph). The machine is CE marked, complying with EC regulations to ensure safe operation.

Usage Features:

Crop Compatibility: Suitable for mowing all types of grass, clover, whole crop, alfalfa, and sorghum.
Cutting Unit: Equipped with durable, reversible knives for high capacity, even with difficult crops.
Conditioning: Fitted with powerful rollers for effective crop conditioning.
Headland Turning: Quick and easy hydraulic lifting of the cutterbar without tools.
Swath Adjustment: Two deflector plates allow adjustment of the cutting swath width to suit the following chopper, aiming for a broad and even swath.
Stubble Height Adjustment: Variable settings for stubble height (15-100 mm) using connecting links and bolts. High skids (20 mm, 40 mm, 80 mm) are available as extra equipment for uneven fields with stones or molehills.
