How to install a rotary tiller by tractor

1. Preparation before installation

Accessories inspection: Ensure that the suspension device has complete accessories, including a middle pull rod, a pull rod (one piece on the left and right), a lift pull rod (two), an adjustment pull rod (limit chain) and a matching pin. ‌

‌Power Matching‌: The power of the tractor must be greater than the power consumed by the rotary tiller to ensure working stability. ‌

2. Installation of suspension device

Pull-tip rod connection: The pull-tip rod is in a figure-eight shape, with one end connected to the tractor and the other end (slightly concave) connected to the rotary tillator; the lifting pull-tip rod has a concave and a wide end connected to the tractor lifting arm, and the narrower end is connected to the pull-tip rod.

‌Adjustment lever and middle tie rod‌: Adjust the short end of the tie rod is connected to the tractor drive sleeve, and the long end is connected to the lower tie rod; the two ends of the middle tie rod are symmetrical, connecting the tractor and rotary tillator suspension assembly respectively.

‌Transmission shaft alignment‌: The transmission shaft should be in a straight line with the tractor power output shaft to ensure the consistency of the left and right cultivating depth.

3. Blade arrangement and installation method

‌Basic Principles‌:

The left and right scimitars are arranged intertwined to balance the bearing load and installed according to the spiral rules. ‌

Each time the knife shaft rotates, only one knife is buried at the same phase angle to avoid blockage and keep the load even.

Common installation methods:

Interleaved installation method‌ (recommended): The left and right blades are arranged interleaved, and the surface of the ground is flat after plowing, which is suitable for plowing before sowing.
‌Interior installation method: The blade is bent towards the center of the knife shaft, and ridges are formed in the middle after plowing, which is suitable for ridge preparation.
‌Exterior installation method‌: Except for the inner installation of the outermost blade, the rest bent outward, and shallow grooves are formed in the middle after plowing.

4. Precautions for operation and maintenance

‌Home speed‌:

Choose 1-2 gears for dry land operations, 2-3 gears for paddy fields, and match the rotation speed of the rotary tillage (188 rpm of dry land, 240 rpm of paddy fields). ‌

‌Operation Specifications‌:

‌Operation specifications‌: Separate the power output shaft when turning to avoid collision of the transmission shaft.
Use the lift, neutral and pressure drop functions of the hydraulic distributor to prevent damage to the hydraulic system.

‌Maintenance‌:

Regularly fill gear oil and grease to check the tightening of the bolts.

5. Safety Tips

When installing, ensure that the tool shaft is subjected to balance force to avoid damage to the machine parts or vibration of the unit due to imbalance.
The central pull rod of the suspension device needs to be suspended at a high point to improve passability and reduce accident risk.
Through the above steps, the efficient matching of the rotary tiller and the tractor can be ensured, the equipment life can be extended and the operation quality can be improved. If you need a more intuitive installation demonstration, you can refer to the video tutorial resources.
