Foreword
GB/T 1592 “Agricultural tractors - Rear-mounted power take-off types 1, 2, 3
and 4” consists of the following three parts:
- Part 1: General specifications, safety requirements, dimensions for master
shield and clearance zone;
- Part 2: Narrow-track tractors, dimensions for master shield and clearance
zone;
- Part 3: Main PTO dimensions and spline dimensions, location of PTO.
This Part is Part 1 of GB/T 1592.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009.
This Part replaces GB/T 1592.1-2008 “Agricultural tractors - Rear- mounted
power take-off types 1, 2 and 3 - Part 1: General specifications safety
requirements dimensions for master shield and clearance zone”.
Compared with GB/T 1592.1-2008, in addition to editorial modifications, the
main technical differences in this Part are as follows:
- modified the standard name;
- changed "wheel track" to "minimum track" (see Clause 1 of this Edition,
Clause 1 of Edition 2008);
- added the requirements for PTO type 4 of tractors (see Clause 1, 4, 5, 6, 7
of this Edition);
- modified the requirements for rotation direction of tractor PTO (see 4.2 of
this Edition, 4.2 of Edition 2008);
- added the method of determination for standard rotary speed of PTO (see
4.3 of this Edition);
- modified the recommended PTO powers at engine rated rotary speed (see
Table 1 of this Edition, Table 1 of Edition 2008);
- deleted “the recommended PTO powers at engine rated rotary speed are
determined in accordance with OECD Rule 1 or Rule 2” (see Table 1 of
Edition 2008);
- added PTO rotary speed, spline, diameter specification and type code (see
Table 1);
Agricultural tractors - Rear-mounted power take-off
types 1, 2, 3 and 4 - Part 1: General specifications,
safety requirements, dimensions for master shield
and clearance zone
1 Scope
This Part of GB/T 1592 specifies general specifications for rear-mounted power
take-off types 1, 2, 3 and 4 of agricultural tractors of which the minimum track
is greater than 1150 mm, including speed, safety requirements, master shield
size and clearance zone of power take-off (for the requirements for the
agricultural tractors of which the minimum track is less than or equal to 1150
mm, see GB/T 1592.2).
This Part is applicable to rear-mounted power take-off of agricultural tractors
(hereinafter referred to as the power take-off / PTO).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 power take-off; PTO
an external drive shaft for transmitting rotational power to farm tool at the rear
of a tractor
4 Technical specifications
4.1 The power take-off is divided into four types (see Table 1).
4.2 The direction of rotation of PTO is clockwise when viewed from behind the
tractor. Unless it is a PTO synchronized with the drive wheels, when the tractor
is driving in reverse, it can rotate counterclockwise.
