The speed of farmland operations for walking tractors (hereinafter referred to as hand-holding) should be determined according to factors such as soil type, surface conditions, soil moisture content, hand-held power, and corresponding agronomical requirements, in order to ensure operation quality and production efficiency. First, the plough hand tractor and the ILS-220 one-way double hoe plough supporting the use of hand drag speed should use 2,3 block. 2. Rotary tiller and rotary cultivator are used together. The speed of dryland operation should be 1, 2 stops, and the rotation speed of the rotary cultivator is 188 rpm. The paddle speed of paddy field should be 2, 3 stops, and the rotary cultivator. The speed is 240 rpm. Third, sowing When the soil moisture content is lower than 20%, the hand drag and 2BG-6A seed drilling machine supporting the use of hand drag speed should choose 2,3 block; when the soil moisture content is greater than 30%, the hand drag speed should choose 2 Block; General, hand drag speed should choose 1,2 block. Fourth, the open hand drag and IKSQ (H) -35A type disk trencher supporting the use, when the soil is soft, shallow depth of the trench, hand drag speed should choose 2 block. In other cases, 1 block is selected. Fifth, open hand drag and IKMP-2 cotton seedling transplanter supporting the use of the hand drag speed should choose 2 block. 6. The harvesting hand pallet and the 4GL-130 harvester are used together. When the local surface is flat, the soil moisture content is low, the crop growth density is normal, the weeds are few and there is no lodging, the speed of the hand dragging should be selected 4 blocks. In other cases, 3 gears are used. Seventh, the benefit seeding hand drag and the IG-120 cover machine are used together, and the hand drag speed should select 2, 3, and 4 gears. 8. Rice paddles are used with the M-74 Hirata Machine. The speed of the hand-pushing should be 3 or 4 stops. Nine, straw returning hand drag speed is generally selected 1,2 block, the actual production of more use of a block.
