Identify the power rating
Engine power is a tractor engine rating. PTO power describes power available through the power take-off under the stated rating conditions. Do not substitute one value for the other or assume a fixed conversion percentage.
Power and speed are separate requirements
A PTO-driven tiller has both a power requirement and a specified shaft-speed arrangement. Matching horsepower alone does not confirm the correct PTO connection, driveline or operating speed.
Include the mounting and load
Working width, implement weight, hitch category and tractor lifting capacity also affect suitability. A trailed or ground-driven implement can have different requirements from a PTO-driven machine. Check the exact model rather than applying a single rule to every implement.
Key Points to Compare
| Item | What it describes | What to check |
|---|---|---|
| Engine power | Tractor engine rating | Read its stated rating conditions |
| PTO power | Power available at the PTO | Compare with the driven implement |
| PTO speed | Rotational speed | Match the specified configuration |
