PTO Drives

PTO Drives, or power take-off drives, are used to transfer power from an engine to a secondary source. Often, they are used on heavy-duty equipment that needs to send power to a hydraulic pump. Choosing the right PTO for your application is important, as the product specifications should vary depending on your industry application, method of PTO engagement, speed output goals and more. Auburn Gear has three PTO models, the model 3, model 5, and model 8. However, our design and engineering teams provide assistance in customizing your PTO drive to meet your specific needs. 

Common Applications 

  • Nut Harvesters
  • Augers
  • Pumps
  • Spinner Spreaders
  • Rotary Tillers
  • Grain Wagons
  • Orchard Sprayers
  • Mower Conditioners

Power Wheel® PTO Drives or Speed Increasers are driven by a PTO shaft at an input speed of 540rpm or 1000 rpm. The traditional simple planetary when driven from output to input will act as a speed increaser, thus, providing the needed speed up to optimize hydraulic pump speed for efficiency.

Model Maximum Continuous HP Maximum Intermittent HP Maximum Input Speeds (RPM) Ratios
HP KW HP KW
3 36 26.8 60 44.7 540 1:3.60
5 50 37.3 75 55.9 540 / 1,000 1:2.79, 1:3.75
8 80 59.7 100 74.6 540 / 1,000 1:2.92, 1:3.92

Application Spotlight – Model 8 

In this nut harvester application, the Model 8 PTO Drive or Speed Increaser provides the needed power to the hydrostat. The hydrostatic pump then, in turn, powers a hydraulic motor which runs a pick up chain mechanism that physically picks up the crop—in this case, nuts. The hydrostat also powers a 70 HP fan for dust and dirt removal from the product. The Model 8 was selected due to the high horsepower requirements of the application, as 75 HP is the minimum horsepower demand.
