It Starts with the Pickup
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 build 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.
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.
Belts and pickups are driven using on-board hydraulic pumps, with hydraulic oil from a 38-gallon reservoir. This large capacity ensures that cool oil is always being circulated through the system. The massive reservoir surface area and specially designed system provide excellent cooling in even the hottest conditions, without the need for an oil cooler.
Floating Windguard and Standard Crop Netting
The floating windguard used on the MM 700 eliminates the need to make adjustments when merging different crops or cuttings. The simple design 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 or fully retracted to match your needs.
Versatile and Adaptable to Your Environment
Multiple Delivery Options
The MM 700 can merge crop to the left, right, split, or if needed, with either wing in the raised position. Having the ability to raise the wings independently is particularly useful for opening up fields 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 10’ wide. Balanced tongue weight during transport and in the field helps the operator maintain control at all times.
No Steering Axle Needed
The MM 700 does not require a steering axle, even on steep hillsides. This is a result of its short wheelbase and has 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.
Dual, wide skid shoes allow each head to rapidly adapt to undulating field conditions while maintaining very low ground pressure. Additionally, the special shape and pivoting of the shoe allow for self-cleaning when lifted into headland position to eliminate crop buildup.
In-Cab Control Terminal
KUHN MM 700 deluxe models feature an in-cab control terminal. Using this simple terminal, you can rapidly make all common in-field adjustments. Quickly select and change conveyor belt direction, shut off belts at headlands and change pickup speed to match crop conditions. You can also hydraulically adjust the pickup height, if the hydraulically adjustable skid shoe option is purchased.
Hydraulic On/Off Belt Control
Create clean and neat ends of windrows to maximize crop uptake and simplify the chopping process. The simple, single button control allows for the belt to disengage quickly to keep crop from being sent into the headland at end rows. Gathered crop can then be sent into the subsequent windrow. Standard on Deluxe models.
Electronic Variable Pickup Speed Control
Using the in-cab control, quickly and easily adjust pickup speed on-the-go to perfectly match crop conditions. With this feature, you can maximize leaf retention, especially if merging drier legumes such as alfalfa. In heavy, grass crops, the pickups can also be sped up to promote faster working speeds.
Hydraulically Adjustable Pickup Height
If the hydraulic skid shoe option is purchased, you can hydraulically adjust the pickup from the cab. Height change is accomplished thru a cylinder mounted in place of the standard turnbuckle. A reference gauge on the right wing of the machine allows for the operator to easily identify his preferred pickup height.
