Twin/Triple Mergers (MM)

With 10.97 m and 12.80 m of pickup in a single pass, the KUHN MM 1101 and MM 1301 MERGE MAXX hay mergers are the largest and most efficient mergers on the market. They are unique in the industry and unmatched in their simplicity of operation, durability and merging capabilities. Designed for commercial operations, the MM 1101 and MM 1301 incorporate 6-tine bar cam pickups with exclusive tine arm wear guards and anti-wrapping rings. The floating windguard ensures the operator lays down smooth and even windrows to make the forage harvester more efficient. The crop netting improves leaf retention into the windrow. Simple and durable mechanical floatation on each head eliminates the need to engage float via the tractor’s hydraulics. ISOBUS compatibility, an industry exclusive, is standard and allows for improved operator ergonomics and reduced fatigue.

Your benefits

It Starts with the Pickup

MERGE at work

High-Capacity Pickups with Integrated Frames

Commercially designed pickups treat crop gently yet are built and tested for extreme use. The central cam design with large 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.

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 in between cuttings and during the off season.

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 guiding 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.

Anti-Wrapping Discs

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

Self-Contained Hydraulics

The hydraulic drive pumps oil through the main hydraulic blocks to run all the functions of the machine, including the pickup speed, belt direction and pickup height. All of these functions are electronically controlled via the tractor’s ISOBUS terminal, or the optional KUHN CCI 50, CCI 800 or CCI 1200 ISOBUS terminals. The MM 1101 and 1301 have larger main steel lines with cleaner hose routings leading to valve blocks now mounted on each head. These features improve hydraulic system efficiency resulting in greater machine capacity. A standard oil cooler provides even greater performance for even the toughest of field conditions.

Versatile and Adaptable to Your Environment


Multiple Delivery Options

The MM 1101 and MM 1301 can merge crop to the left, right, split or with either wing in the raised position. Having the ability to raise the wings independently is particularly useful for opening up fields, merging around obstacles or cleaning up point rows in irregularly shaped fields.

Narrow & Simple Transport

The simple folding design allows quick transition from field to road. Transport is a narrow 12’1” wide. Balanced tongue weight during transport and in the field helps you maintain control at all times. At 10 GPM of hydraulic flow, field to transport position is possible in approximately 12 seconds

No Steering Axle Required

The MM 1101 and MM 1301 do not require a steering axle, even on steep hillsides. This is a result of its short wheelbase and is an advantage over competitive mergers. This simplification reduces routine maintenance and improves overall reliability. An added benefit of the short wheelbase is reduced tongue weight, so the tractor does not get “pushed around” by the merger.

Constant Float® Suspension

A simple and effective mechanical spring suspension system is utilized for superior float characteristics. This unique design, inspired by the proven KUHN trailed mower, eliminates complicated hydraulic requirements and the need for tractor float valve engagement, unlike other mergers in the industry.

Floating Skid Shoes

Dual, wide skid shoes allow each head to rapidly adapt to undulating 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 allow 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.

Time Saving Features

2-Point Hitch.jpg

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. 3/4/4N quick hitch compatible. An integrated dual stand provides a large footprint and swings and locks easily when attached to the tractor.

Greasing System

A standard central grease valve ensures all key points are greased easily from one location.

To also cut down on maintenance, a ¼ turn valve shuts off oil during filter changes and the handle sticks up preventing the shield from closing, so the machine is not operated with the oil shut off. Additionally, a larger fill port cuts down on oil change time.

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 guard 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 which require you to remove tine bars and tines to replace worn bearings. Additionally, a specially formulated bearing material maximizes bearing life and minimizes friction.
