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

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).
