John Deere 3550 Extra Horsepower Notes
Horsepower note
The John Deere 3550 has almost no visible gap between the listed engine horsepower and PTO horsepower ratings.
PTO note
Use the John Deere 3550’s 125 hp PTO rating when sizing implements; the 125 hp engine rating is not the number the implement actually receives.
Drawbar note
For plows, ground tools and pull-type loads, the John Deere 3550’s 105 hp drawbar horsepower says more than engine horsepower alone.
Power-to-weight note
At 8,000 lb and 125 hp, the John Deere 3550 works out to about 64 lb per engine horsepower, making it light for its power, so traction and ballast can become the limiting factor before engine power.
Engine note
For engine identification, the John Deere 3550 is listed with engine model John Deere 5.9L 6-cylinder, 5.9 L displacement, 6 cylinders, rated at 2,200 rpm.
Torque / RPM note
The John Deere 3550’s 70.8 lb-ft torque rating works with its 2,200 rpm rated speed, so load response depends on both numbers.
Official information note
Mistakes do happen. Horsepower, PTO horsepower, drawbar horsepower, weight and engine specs can change by year, market, engine option, cab, transmission and test standard. Please check the operator manual and official deere.com website for official information.
