Frequently Asked Questions
Variable Speed Rotary Tiller enters the field for use.
3. Ground use:
(1) When entering the field for cultivation, avoid applying excessive hydraulic pressure and dropping the implements all at once. Instead, gradually engage the hydraulic system as the main machine moves forward, allowing it to enter the soil smoothly and perform cultivation. Adjust the tractor’s throttle to keep the engine speed around 2,000 rpm.
(2) During operation of the Rotary Tiller, the host’s hydraulic system is in the floating position. Lower the implement to the required tillage depth and ensure it remains level. The wear-resistant plates on both sides of the implement should be 12 cm above the ground. Note: When the tillage depth exceeds 15 cm, slightly adjust the central pull rod so that the rear of the implement is slightly higher, which facilitates soil emergence.
(3) During field operations, the angle between the universal joint and the drive shaft must not exceed 10°. At the headland turn, the cutter tip should be lifted off the ground by 15–20 cm.
(4) Drivers undergoing parking training should pay attention to certain matters, especially considering different soil types, varying moisture levels, and different operational requirements (see sections 1.3 and (5) for details). This highlights the high efficiency and low fuel consumption of the Variable Speed Rotary Tiller. Drivers may only leave after ensuring they have operated correctly according to regulations and maintaining constant communication.
(5) Methods for varying speeds: On the same plot of land, with the same tractor and the same tillage and seeding quality (such as tillage depth and soil crumbling), the method of using different speeds to achieve varying levels of efficiency is:
① By soil type: A. Clay soils—hard, dry soils: Choose low speed (energy-saving); for loose, soft soils, select high speed and a higher gear for the main machine (high efficiency). B. Sandy soils: Choose low speed and a higher gear for the main machine (energy-saving and highly efficient). C. When sowing in fields with tall stubble and thick stalks, select high speed (fewer straw and weed residues in the seedbed, preventing blockages).
② By engine horsepower: A—high horsepower (a big horse pulling a small cart); suitable for clay soils, choose high speed, and set the main engine one gear higher (high efficiency); B—suitable for sandy soils, choose low speed, and set the main engine one gear higher (high efficiency).
Warning! Dear YAAO user, if you buy a variable-speed device but don't adjust it as required, it's like a blind person lighting a lamp! You'll only end up spending more on the purchase without reaping the pure profit you deserve.
