John Deere Z955R Extra Horsepower Notes
Horsepower note
For power comparison, the John Deere Z955R sits at 29 hp engine horsepower with 25.5 hp available at the PTO.
PTO note
With 25.5 hp at the PTO, the John Deere Z955R 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
At 24.5 hp drawbar power, the John Deere Z955R is about 4.5 hp below its engine rating once power is measured as pull at the ground.
Power-to-weight note
Using 1,200 lb operating weight and 29 hp engine power, the John Deere Z955R comes out at roughly 41.4 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 Z955R’s 50.3 cu in engine makes 29 hp, or about 0.6 hp per litre.
Torque / RPM note
The John Deere Z955R’s 45.7 lb-ft torque rating works with its 3,600 rpm rated speed, so load response depends on both numbers.
Official information note
