M1 Series Windrower

Next level Harvesting Performance

M1 Series Windrowers continue MacDon’s tradition of bringing harvesting innovation to the field. These all-new Windrowers deliver power, performance, comfort, and speed. The powerful Cummins engines provide more than enough header drive capacity to power through the toughest harvesting situations. Our patented CrossFlexTM suspension makes the 18 mph (29 km/h) in-field and 28 mph (45 km/h) road speeds feel like a relaxed cruise. The high-back leather vented and heated seat, auto climate control, Bluetooth® radio, and the 360° Night Vision from 8 LED work lights will keep you comfortable and cutting long after the sun goes down. Setting a new standard in Windrower technology, the M1 Series is the next level of harvesting performance.

Product Features

Powerful Performance

Choose from a Cummins 6.7 liter turbo diesel engine that delivers 248 horsepower at 2200 rpm or a Cummins 4.5 liter Turbo with 173 horsepower 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 its Cool Under Pressure

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.

A Fast Smooth Ride & Clean cut

MacDon’s all-new patented CrossFlexTM 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.

Faster in & Between Fields*

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.

*Always follow local traffic laws and regulations.

360˚ Night Vision

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. 

DWA Saves Time & Money

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. 

Massive Crop Clearance Ability

Featuring the Industry’s Best Crop Clearance with 46” (117 cm) of height and 169” (429 cm) of width, big bushy swaths flow effortlessly under the M1240. Header lift height is improved too, 3" higher than our previous model.

Track your Harvest Performance

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

Precision Controls

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. 

Smooth Ride

MacDon’s Ultra Glide® cab has a four-corner independent gas shock suspension system featuring stabilization to prevent cab roll. The CrossFlexTM 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.

Deluxe Comfort & Productivity

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.
