Rotary cultivator Rotary rakes in paddy field tips
Jul 18, 2016

Master Rotary rake method in paddy field on rice growing and agricultural machinery benefits improve greatly. Therefore, Paddy Rotary rake operation should have the following elements:

1. Amount of water: there is too much water, easy oars, do not meet quality requirements; too little, is not easy to rake, also increases the friction of farm machinery in the soil. So. Should have in the field before the Rotary Harrow 2 hours-4 hours, when water depth of 6-8 cm.

2. Plow installation: according to soil surface conditions tiller plow installation direction of the elbow, flat Ridge job Coulter elbows outward installation filled ditch job, Coulter elbow to install. Leakage mounted plow blade shafts left and two on the far right when Coulter, two bolts about 10 cm long, excluding Coulter shaft wrapped around grass.

3. Rotary Harrow speed: walking tractor forward speed and a Coulter rotational speed depending on the circumstances may be. Not plow the stubble fields first when tractors can be selected using the slow-forward, Coulter axis to select low speed; rotary second to third and plowing fields, tractor can choose a slower speed, Coulter-axis high speed can be used.

4. The direction of travel: the hand rake method is used, the edge form a heavy rake the field coil, saving time and fuel. Oblique rake method should be used in the right direction, and locomotives along the field's diagonal left or right a harrowing picture starts to Harrow tillage, gradually expanded outwards, last rake around the edge of a circle. This method of high efficiency, low fuel consumption, good quality.

5. Harrowing times: according to agronomic requirements for rice planting, seedling-throwing paddy fields, generally trailing 2-3 times for the best artificial planting fields, 2 times to rake as well. Too many harrowing times may harm the soil aggregate structure, cause soil compaction and will accelerate agricultural machinery wear and oil consumption, harrowing unevenness and small numbers are not up to the agronomic requirements.

6. Beware the sliding trap: operations marked the edge with bamboo sticks in ponds and ditches. Once the sliding trap, piling self-help approaches can be taken. Namely, about 5 metres in front of the locomotive for a stake and tied to the stake in wire rope, tied the other end to the drive wheels. Gears, shake the handle turn the crankshaft, making walking tractor. Through around the driving wheel on the rope to pull the tractor and the pit. In addition, oxen or tractor power can also be used to pull it out.
