What Size Rotary Tiller for Tractor?

What size rotary tiller for tractor?

Choosing the appropriate size of rotary tiller is crucial for improving tillage efficiency, reducing energy consumption, and extending equipment lifespan. The following is a detailed selection guide that takes into account tractor horsepower, farmland conditions, soil type, and brand characteristics.

1、 Matching the size of rotary tiller with tractor horsepower

The working width (size) of the rotary tiller must match the horsepower of the tractor, which is the primary consideration when choosing a rotary tiller:

Recommended working width of rotary tiller for tractor horsepower

20-35 horsepower 1.25-1.6 meters

36-50 horsepower 1.6-1.8 meters

50-70 horsepower 1.8-2.0 meters

70-95 horsepower 2.0-2.3 meters

90-110 horsepower 2.3-2.5 meters

2.5-2.8 meters above 100 horsepower

Key principles:

The power of the tractor used in conjunction should exceed the power consumption of the rotary tiller by 10-15%

The speed of the blade shaft should be controlled within the range of 200-280 revolutions per minute, as being too high or too low can affect the quality of cultivation

The height of the tractor power output shaft above the ground determines the selection of the high and low boxes for the rotary tiller: if it exceeds 60cm, the high box is selected; if it exceeds 65cm, the high box is selected; if it is below 60cm, the low box is selected

2、 Farmland conditions and selection of rotary tiller size

Farmland size and recommended size

Farmland area (mu) Recommended terrain conditions Rotary tiller width Daily operating efficiency

5-15 small plots/terraces 0.8-1.2 meters, 8-12 acres

15-30 medium flat plot 1.4-1.8 meters 15-25 acres

30-100 large flat farmland 2.0-2.5 meters 25-40 acres

Large scale farms of 100 or more, ranging from 2.8-3.2 meters to 40-50 acres

3、 The influence of soil type and tillage depth

1）. Suggestions for size selection of different soil types

Soil type characteristics, selection points for rotary tiller, recommended horsepower increase range

Loose and easy to cultivate sandy soil with a standard width is sufficient, and it is important to note that the wear resistance of the blades does not need to be increased

Clay is sticky and difficult to break. Choose a width that is 10-15% smaller, and increase the cutter shaft speed by 15-20% horsepower

Salt alkali flooring is prone to corrosion. Choose anti rust materials to reduce width and increase tillage function by 10-15% horsepower

Choosing manganese steel blades for high stone content in gravel ground reduces width by 20% and increases horsepower by 25-30%

2.） Selection of machine models corresponding to cultivation depth

Cultivation type, depth range, rotary tiller type

12-16cm standard rotary tiller for shallow tillage

Conventional tillage 16-25cm reinforced rotary tiller

Specialized deep plowing machine for 25-40cm deep plowing

Ultra deep tillage 40-50 cm deep loosening rotary tillage combined operation machine

Attention: During deep plowing operations, the width of the rotary tiller should be reduced by 15-20% compared to conventional options to ensure sufficient power

4、 Scene representation

Brand performance in different scenarios

Southern paddy field: Loong Boat agricultural machinery is designed to prevent grass entanglement, and the failure rate of transmission system is reduced by 40%

Hilly area: Wode Agricultural Machinery 15 horsepower air-cooled diesel engine, maintaining 85% power output on a 30 ° slope

Deep cultivation of hard soil: Dongfanghong Military Anti rust Technology, deep cultivation of 35cm (industry average 20-25cm)

Sticky soil: Haofeng manganese steel blade gravel ground operation, blade replacement frequency lower than industry average

Facility agriculture: Dahua Bora narrow body model (wheelbase ≤ 90cm), electrically controlled continuously variable speed precision operation
