Alpha Pro Shot Laser System: Transmitter, Receiver and Control Box Explained

A laser land leveller is only as good as the laser system that guides it. The blade does the cutting and filling, but it is the laser system that decides, many times a second, whether the blade should go up or down. Every Rattan Laser Leveller comes with the Alpha Pro Shot laser system, and in this article we explain each part in simple words.

The three parts of the Alpha Pro Shot system

PART 01

Transmitter

Sits on a tripod at the field edge and spins a 360° laser beam across the field. Self-levelling, with dual-axis control for grading in any direction.

PART 02

Receiver (MEI 367SB)

Mounted on the leveller mast. It reads the laser beam, and bright LED arrows show the blade position: up, down or on-grade, in real time.

PART 03

Control box

Sits within reach of the tractor driver and turns the receiver signal into hydraulic commands. AUTO or MANUAL mode at the press of a button.

How the signal travels: from laser beam to blade

1. The transmitter spins its laser beam and creates an invisible, perfectly level “reference plane” over the whole field.
2. As the tractor moves, the receiver on the leveller mast keeps checking where that beam hits it. If the beam is high on the receiver, the blade is too low; if it is low, the blade is too high.
3. The control box reads this signal and, in AUTO mode, opens or closes the hydraulic valve on its own.
4. The hydraulic cylinder lifts or drops the blade, so it cuts the high spots and fills the low spots, without the driver touching anything.

AUTO and MANUAL mode

In AUTO mode, the system controls the blade by itself and the driver only steers the tractor. MANUAL mode lets the driver raise or lower the blade with the buttons, which is useful when moving the leveller, turning at the headland, or doing a quick first pass.

Why the laser kit should come with the leveller

When the leveller and the laser system come from different places, farmers often face fitting and compatibility problems. Rattan Agro Tech is India’s largest distributor of Alpha laser systems, and every Rattan Laser Leveller ships with a factory-calibrated Alpha Pro Shot kit: transmitter, receiver and control box, ready to work out of the crate. There is no third-party sourcing and nothing to match up yourself.

Tips for accurate levelling

• Set the tripod on firm ground and make sure it does not get bumped while you work. If the transmitter moves, the whole reference level moves with it.
• Keep the beam clear. Place the transmitter high enough that the beam passes over the tractor cabin and is not blocked by trees or buildings.
• Let the transmitter settle after switching it on, so it can level itself before you start.
• Charge the batteries before the day’s work so the system does not stop in the middle of a field.
• Protect the equipment from dust, rain and knocks. Store the transmitter in its case and wipe the receiver window clean.
