Choose from a Cummins 6.7 liter Turbo Diesel engine that delivers 185 kW (248 HP) at 2200 rpm or a Cummins 4.5 liter Turbo Diesel with 129 kW (173 HP) at 2400 rpm. Either way, more engine power combined with increased header drive capacity means M1 Series Windrowers are ready for any harvesting situation

Keeping their cool under pressure, M1 Series Windrowers use a new dual radiator design to draw air from the cleanest location, behind the cab. To keep the clean air flowing constantly a hydraulic-drive reversing fan works on the go to blow out unwanted debris, keeping the engine and hydraulics running cool and efficiently, without the need of operator input.

MacDon’s all-new patented CrossFlex Suspension makes the 18 mph (29 km/h) in-field and 28 mph (45 km/h) road speeds feel like a relaxed cruise. This unique design absorbs impact from rough terrain allowing smooth harvesting no matter the field condition.

MacDon’s optional Double Windrow Attachment lets you achieve the ultimate windrow when paired with a rotary disc header. Ideal for keeping today’s large forage harvesters working at capacity, this option allows operators to combine up to three passes into a single windrow. That translates into significant time and fuel savings in the field.

* Double Windrow Attachment is not compatible with all units.

Thanks to MacDon’s patented Dual Direction® technology you can switch from field to road mode in seconds and travel at speeds of up to 28 mph (45 km/h). In most cases there’s no need to detach the header, saving you time and labor when moving from field to field. D1XL Series Draper Headers can be easily transported at 20 mph (32 km/h) with MacDon Windrowers using our Slow Speed Transport system. Either way, you’ll be spending less time in transport and more time cutting. 

Featuring the Industry’s Best Crop Clearance with 115 cm (45” clearance) of height and 386 cm (152”) of width, big bushy swaths flow effortlessly under the M1. Header lift height is improved too, 7.6 cm (3”) higher than our previous model.

The deluxe cab option takes performance to the next level with our 360˚ Night Vision from 8 high power LED work lights. The bright halo of light from our 360˚ Night Vision lets you work safely long after the sun goes down. 

Operators will enjoy the all-new 17.8 cm (7”) Harvest Performance Tracker. Track your harvest performance with an easy to read interface providing on board diagnostic readings and user customizing features.

The new two stage controls allow for faster and more precise positioning of the header. Users can easily program up to three One-Touch-Return buttons for fast in-field control of the header’s height, tilt, cutting speed, reel, and draper operation. 

MacDon’s Ultra Glide® cab has a four-corner independent gas shock suspension system featuring stabilization to prevent cab roll. The CrossFlex Suspension is designed to absorb impacts from rough terrain, and an air ride seat means operators will enjoy a smooth, comfortable, and controlled ride reducing fatigue and keeping them cutting all day long.

Our deluxe cab option takes comfort and performance to the next level, featuring heated and vented leather seating, power mirrors, and 360˚ Night Vision from 8 high power LED work lights. The bright halo of light from our Night Vision lets you smoothly transition from day to night.

The simple serviceability of the M1 Series means you'll spend less time on maintenance and more time cutting. DEF and fuel fills happen right from ground level, and the 530 liter (140 gallon) tank keeps you cutting all day. Check the oil without lifting the hood and see the hydraulic level at a glance from the sight glass. Access to the radiator and cooler box is easy. The sliding platform allows quick access to hydraulic hook-ups for quick header connection, and tools can be kept close by in our easy access lockable toolbox conveniently tucked away in the platform.

For those working in extremely hilly fields, order an M1170HT. These High Torque wheel drive units have a higher final drive ratio for increased drive wheel torque, allowing harvesting performance on slopes greater than 18 degrees (32% grade).*

*Factory order. Will decrease speed on non-extreme and flat ground conditions.
