This standard applies to agricultural and forestry tractor models. The composition of models is JE/T9831-1999. ZB16u00488. 2. The model of the tractor is composed of a series of codes, power code, type code, function code and distinguishing mark. The order of the code is as follows: zoning mark, function code, type code ... 2.2 Series codes are represented by two letters (the last letter is 1 or 0) to distinguish different series and models. If not necessary, the series code can be omitted. 2.3 Power code is represented by the engine rated power value (in kW) multiplied by an integer near the coefficient of 1.36. 2.4 Type code uses underscore integers, such as rear-wheel drive four-wheel typebzxZ.net
1 single-axle type
2 single-axle type||t t||One wheel or juxtaposed front wheel
Four wheel dynamic
2.5 Function codes use the following letter symbols: (blank) General agricultural use
Orchard use
H Highland source cultivation use
Log collection
Industrial forestry use
3 Self-propelled chassis type
9 Ship type
P Slope use
s Paddy field use
T Transportation use
Y Horticulture use
2 Marshland use
2.6 Structure After major improvements, the structure can be marked with a distinguishing mark, which is represented by Arabic numerals. Approved by the State Machinery Industry Bureau on August 6, 1999 and implemented on January 1, 2000

3.1 The letter symbol of the series code is selected by the T factory. 3.2 Select one of the type code and the current function code to fill in. JBT9831—1999
3.3 If other numbers must be used as type codes or other letters as function codes, they should be approved by the department responsible for industry standards. 3. 4 Examples
