John Deere M665 Extra Horsepower Notes
Horsepower note
The John Deere M665 lists engine horsepower and PTO horsepower very close together at about 25 hp.
PTO note
With 25 hp at the PTO, the John Deere M665 is best matched to finish mowing, light-duty rotary cutting, light tilling and small utility PTO jobs; heavy hay tools, large augers and high-load PTO equipment are not the natural match for this power class.
Drawbar note
The John Deere M665 combines 20.5 hp drawbar horsepower with 1,200 lb operating weight, so traction and ballast can matter as much as power for pulling jobs.
Power-to-weight note
Using 1,200 lb operating weight and 25 hp engine power, the John Deere M665 comes out at roughly 48 lb per engine horsepower, meaning it is light for its power, so traction and ballast can become the limiting factor before engine power.
Engine note
The John Deere M665’s 44.2 cu in engine makes 25 hp, or about 0.6 hp per litre.
Torque / RPM note
Use the John Deere M665’s 3,600 rpm rated RPM when comparing engine specs across similar tractors.
Official information note
