Laser land leveler (A to Z)

welcome friends today we will discuss about laser land leveler In this video we will focus on Advantages of laser leveler why laser leveling required? what are different components of laser leveler will discuss inter connectivity of different components point to remember while purchasing LL point to remember while purchasing LL what is new in laser leveling what is new in laser leveling how to trouble shoot the laser leveler how to trouble shoot the laser leveler This video is a complete guide on LL contains lots of information. Therefore, I request you to watch till end This information will be benefical for operation of LL First of all will discuss why laser leveling ? First of all will discuss why laser leveling ? this is a field left side water channel for irrigation on right side is bund Flood irrigation water flows from left to right Flood irrigation water flows from left to right Irrigation water percolates down the field More depth of water is applied on left side that is near the irrigation channel than on right side lesser water depth towards right side what we want in the field the depth of irrigation water should be like white line i.e depth is uniform in the entire field how to achieve this? this is only possible if irrigation water flows quickly from left to right this is only possible if irrigation water flows quickly from left to right Laser leveler can help in this regard laser leveler reduces the undulation in the field this helps to move the irrigation water quickly in the field LL helps to uniformly distribute water this is a chili field the vegetables are sensitive to water application this is why these are grown on beds to get rid of excess water the crop stand in the field is poor where there is flooding of water the farmer who are doing potato cultivation this machine is very good for them the laser leveling should be done once in a period of three years the laser leveling should be done once in a period of three years next we have different components of LL 1. Laser transmitter 2. laser receiver 3. Control box 4. hydraulic valve 5. laser survey receiver and bucket Lets study each component one be one 1. Laser transmitter. this component is placed outside the field we want to laser level the purpose of transmitter is to generate a laser beam with zero slope above the field to be leveled This is costliest component of LL next is laser receiver this receives laser signal generated by transmitter receiver is mounted on the mast attached to the bucket of laser unit next component is control box this is placed near to the tractor operator the operator control the whole system through the control box the operator can move up or down the bucket with control box next component is double acting hydraulic valve this is a basically a hydraulic fluid direction control valve ie the hydraulic oil will move in which gallery weather to raise the bucket or to lower the bucket next is laser eye for conducting the field survey

next is scraper or laser bucket its purpose is to cut and fill the soil in the field so these were the different components of LL now we will have look at on the interconnection of different components of LL The laser transmitter generates the laser beam The receiver generates equivalent voltage signal wrt to laser beam incidence on its surface Receiver is connected to control box through a wired connection Control box gets signal from the receiver on the basis of signal voltage the control box estimates the height of bucket/receiver at a each time interval Control box is connected to double acting hydraulic control valve the through 2 solenoid switches Control box sends electrical signal to solenoid switch to rasie or lower the bucket wrt to the leveler position to laser beam the hydraulic valve is connected to double acting hydraulic jack the double acting hydraulic valve sends oil in galleries to raise or lower the bucket to level the field the bucket is automatically raised in the field where soil filling is required similarly, the bucket is automatically lowered in the field where soil cutting is required this cut and fill system works continuously in the entire field this is how the laser leveler levels the entire field automatically Friends next is tips to keep in mind while purchasing a LL Important considerations are LL is very costly machine having price around 3.5 lakh INR one must keep in mid about the after sale service reputation of the laser supplier i.e is the LL service is easily avialabe in your area or not? it has been observed the operational window of LL is around 2 to 2.5 months after harvesting wheat and before planting of paddy crop if timely service by the service provider is not given then the LL will remain idle for peak working period here is the list of different manufactures of the LL in India therefore, keep in mind about the after sale service of LL next is range of transmitter this is laser transmitter its range can be 200 m ……1500 m this range is diameter the smaller range lesser price and larger range more price friends 200 m range LLis good enough for leveling a field of 6 acres in one go if we keep the LL in the middle of big field it can do 6 acres in one go we dont go for leveling a bigger are more than 2 to 3 acres at one go as it is time consuming and uneconomical therefore, the transmitter with 200 m range is good enough for Indian farm conditions and can save money next is type of scraper/bucket you can see the bucket tires The wheel section of LL is critical for good performance of LL LL uses the wheels as level sensing unit LL uses the wheels as level sensing unit more the contact area of wheels is in touch with the soil surface more is the accuracy of LL more the contact area of wheels is in touch with the soil surface more is the accuracy of LL more the contact area of wheels is in touch with the soil surface more is the accuracy of LL earlier laser bucket was with 2 wheels

next modification was 4 wheels on one axle in this you can see the bucket wheels have more contact with soil compared to two wheel bucket in this you can see the bucket wheels have more contact with soil compared to two wheel bucket It has double soil contact compared to single wheel bucket thats is why this LL bucket is better Next is laser bucket with tandem wheels Next is laser bucket with tandem wheels this arrangement of wheels have better performance over the previous two buckets this arrangement of wheels have better performance over the previous two buckets if you want to purchase a new LL go for bucket having tandem wheels if you want to purchase a new LL go for bucket having tandem wheels if you want to purchase a new LL go for bucket having tandem wheels next tip while purchasing LL is about the control box Two types of control boxes are available in market Two types of control boxes are available in market Analog (left) and digital (right) Analog (left) and digital (right) one should not buy digital control box As there is a problem of frequent resetting in the digital control box As there is a problem of frequent resetting in the digital control box therefore, Go for analog control box therefore, Go for analog control box therefore, Go for analog control box next is aspect is power mast this is how the power mast look like this is electric motor in side the casing we have 12 V DC motor the operator can set the laser leveler form the driver seat therefore its is easier for the driver to set up the LL therefore its is easier for the driver to set up the LL therefore its is easier for the driver to set up the LL this is a additional feature Next is expenditure on the LL Next is expenditure on the LL i.e break even usage of LL?? i.e break even usage of LL??
