MacDon M155 E4 SP Windrower


M155 E4 SP Windrower


The Tier 4 emission regulations are here and MacDon approached this change in the industry the same way we approach everything... by delivering the best possible performance package to our customers. Our new M155E4 Self-Propelled Windrowers go above and beyond regulation to bring you the harvesting performance you rely on from MacDon.

More Power: 155 HP tuned for performance to handle fluctuating loads in less than ideal harvesting conditions. Better Fuel Economy: Highly efficient engine with DEF consumption as low as 3% of fuel. Our DEF tank has been sized to provide up to 75 hours of use between fills. Proven Reliability: Proven Cummins engine with single turbo delivers reliable performance you can count on. Less Complicated: Our Tier 4 diesels have no DPF (Diesel Particulate Filter) making this a low maintenance Tier 4 system. Less Noise: Our Tier 4 engines run smoother and quieter than previous engines used in MacDon Windrowers.

Our 5 Year (3000 hour) parts and labour Tier 4 component warranty covers; after treatment canisters and related wiring, after treatment piping, clamps, DEF system, and charge air cooler.

New larger radiator and fan keeps things cooler under the hood increasing overall engine efficiency and decreasing fuel consumption. Cooler hydraulics put less strain on the system improving its reliability long-term.

Now standard on all 2015 M155E4 Windrowers, Hydraulic Center Link and Warning Beacons.
