Q140
The effect of LGLL (Laser Guided Land Levelling) lasts for
A.
1 - 2 years
B.
2 - 3 years
AnswerC.
3 - 6 years
D.
4 - 9 years
Answer: Option B
Solution
Answer: Option B
Solution:
LGLL stands for Laser Guided Land Levelling. As per the studies it is believed to reduce greenhouse gas emissions by saving energy, reducing cultivation time, and increasing input efficiency. It works through a laser transmitter which transmits a laser beam, which is intercepted by the laser receiver mounted on the leveling bucket. The control panel mounted on the tractor interprets the signal from the receiver and opens or closes the hydraulic control valve, which further raises or lowers the bucket. Its effect lasts for 2 - 3 years.
