Standard rpm of a tractor PTO drive.
A
360 rpm
B
280 rpm
C
540 rpm
D
Use
Explanation: 

Detailed explanation-1: -The pulley arrangements are made with the standard PTO speed in mind. Prior to 1958, the standard PTO speed was 536 rpm. Later this speed was changed to 540 rpm and another speed was added to the standards i.e. 1000 rpm.

Detailed explanation-2: -When operated at full recommended speed, a PTO shaft will rotate clockwise at 540 revolutions per minute (rpm), which equals 9 revolutions per second, or at 1, 000 rpm (16.7 revolutions per second). As shown in the Table 1, a 540 rpm shaft travels 7.1 feet per second, while a 1, 000 rpm shaft turns 13.1 feet per second.

Detailed explanation-3: -Power Take-Off (PTO) Stub The PTO and drive shaft rotate at 540 rpm (9 times/second) or 1, 000 rpm (16.6 times/second) when operating at full recommended speed. At all speeds, they rotate in proportion to the speed of the tractor engine.

Detailed explanation-4: -Note: Check to see if the horsepower and torque capacity of the PTO you are selecting is within the operating range required. 1. You must know the RPM you wish to operate your vehicle at while running your application. We find that most operators generally run anywhere between 1100–1300 RPM, but it can vary.

Detailed explanation-5: -By engaging 540E mode, the operator changes the gear reduction ratio keeping the PTO spinning at 540 rpm but lessening the engine rpm. When the operator shifts the PTO into the standard 540 mode, a different gear reduction ratio is used to operate the PTO at 540 rpm at the standard PTO rated speed of the engine.
