Multiple Delivery Options

The MM 890 hay merger is the largest twin merger in the industry and can merge crop to the left, right, split or with either wing in the raised position. With two 15’ heads, the MM 890 has the ability to 50/50 split leaving all windrows with an even amount of crop for better harvesting efficiency. Having the ability to raise the wings independently is particularly useful for opening up fields, merging around field obstacles or cleaning up point rows in irregularly shaped fields.

IntelliMerge™ ISOBUS Control System

The IntelliMerge™ ISOBUS control system allows the operator to run the machine, make adjustments, receive performance feedback and carry out diagnostics. Operators can tailor their machine to field and crop conditions to maximize their efficiency.

OptiSense™ Belt Stall Indicator

The OptiSense™ belt stall indicator alerts the operator when the belts start to slow down when approaching the capacity of the machine. This gives the operator a chance to react before the machine plugs. If the belts stop, the sensor will shut down the machine to avoid damage to the belts and further plugging of the machine. The conveyor direction arrow will be red to identify the stalled conveyor. This is done by monitoring the idler roller speed on each conveyor. This feature helps the operator optimize performance, keeping the machine moving across the field for improved productivity.

Constant Float® Suspension

A simple and effective mechanical suspension system is utilized for superior flotation. This unique design, inspired by the proven KUHN trailed disc mower, eliminates complicated hydraulic requirements and the need for tractor float valve engagement, unlike other mergers in the industry. The range of suspension on each pickup is 14” (+8”, -6”).

Narrow and Simple Transport

The simple folding design allows quick transition from field to road. Transport is a narrow 10’3” (3.1 m) wide and transport height is 12’ (3.7 m). Balanced tongue weight during transport and in the field helps you maintain control at all times. Field to transport position is accomplished quickly as only one hydraulic valve per head is used for folding.

High-Capacity Pickups with Integrated Frames

Commercially designed pickups treat crop gently, yet are built and tested for extreme use. Chrome-moly tine bars greatly improve strength and wearing characteristics. The central cam design with heavy-duty sealed cam followers provide extra-long life even in the toughest conditions. KUHN high-capacity pickups are designed and built with integrated frames to improve the strength and durability of the pickups and keep the machine looking clean as there is no place for crop to catch and build up.

Floating Windguard and Standard Crop Netting

The floating windguard eliminates the need to make adjustments when merging different crops or cuttings. The simple geometry of the floating linkage means the windguard is automatically optimized for differing volumes of crop. The long, curved fingers provide excellent crop guidance onto the center of the belt for fluffy and even windrow creation. Standard crop netting greatly limits leaf loss during transition to the belt and ultimately improves leaf incorporation in the windrow. You can adjust the netting from being fully extended to halfway to match your needs.

Heavy-Duty Belt Conveyors

Commercial-grade belt conveyors allow the crop to be effectively transitioned into the windrow, regardless of discharge side. The conveyor belt is self-cleaning and requires no tracking adjustments. Each conveyor has an easy-to-access splice for fast removal or replacement, if necessary due to maintenance and normal wear.  A quick-release belt tensioning system simplifies storage and routine adjustment. Easy adjustment from one side maintains uniform pressure over the width of the belt. It is recommended to take the tension off of the belts between cuttings and during the off season.

Anti-Wrapping Discs

To minimize wrapping in long crops, such as oats or long grasses, HDPE anti-wrapping discs are installed at the ends of the pickups and rotate with the tine bars. This small improvement greatly reduces the dead space where long crop can wrap, as seen with competitive pickup style mergers.

Floating Skid Shoes

Dual wide skid shoes allow each head to rapidly adapt to rolling field conditions while maintaining very low ground pressure. Floating skid shoes are a KUHN exclusive. The pivoting action allows the pickups to float over pivot tracks and rough terrain. Additionally, the special shape and pivoting of the shoe allows for self-cleaning when lifted into headland position to eliminate crop buildup. The skid shoes are reversible on their mounts for even wear and longer life.

Hydraulic Controls

The MM 890 requires two tractor hydraulic valves to control the raising/lowering of the pickup as well as the machine’s folding functions. The suspension system on the mergers utilizes a slotted link, so the tractor hydraulic valves do not need to be put in the float position.  The PTO hydraulic drive pumps oil to run all the functions of the machine including pickup speed, belt direction, and pickup height. One solenoid on each block is used for pickup speed and the other two solenoids for belt direction. All of these functions are electronically controlled via the IntelliMerge™ ISOBUS Control System on the tractor’s ISOBUS terminal, or the optional VT 30 or CCI 50 control box on a non-ISOBUS tractor.

Central Lubrication System

The MM 890 merger is equipped with a central lubrication system. All folding and suspension components requiring lubrication are greased from a single point. This system is not just a grease bank but will ensure the proper amount of grease is routed to each location on the machine while the operator needs to only grease a single zerk. Optionally an auto-lube system can be added to further reduce the time needed for routine maintenance.

2-Point Hitch

The specially designed 2-point hitch makes hookup quick and easy. The swiveling headstock eliminates driveline chatter and allows up to 90-degree turns. The hitch is Cat. 2/3N/3/4N quick hitch compatible. An integrated stand provides a large footprint and swings and locks easily when attached to the tractor. The pins on the 2-point hitch must be 26.5 inches off the ground. This keeps the machine level with the skid shoes running flat against the ground and keeps the tines from hitting the ground.

Bearing Wear Sleeves

Exclusive in the industry, standard bearing wear sleeves maximize tine bar life by providing an easily replaceable split mounting surface. If you're merging in abrasive soils, you'll especially appreciate this feature as a wear sleeve can easily be replaced, with the tine bar installed, in under one minute.

Split Bearing Design

The two-piece poly tine bar bearing greatly simplifies periodic maintenance. Its design allows you to replace the bearing in under one minute, unlike competitive machines that require you to remove tine bars and tines to replace worn bearings. Additionally, a specially formulated bearing material maximizes bearing life and minimizes friction.
