Grass Measuring & Management System Grasshopper is the most accurate grass cover measurement system available on the market today. The Grasshopper algorithm was developed and validated over a three year period by True North Technologies and at the Moorepark Grassland Research Station in Ireland.
Grasshopper is very easy to use. Grasshopper works on the principle of measuring the compressed sward height with millimeter accuracy. As you measure, you have full control over the moment the measure is taken – eliminating angular drop problems experienced with other methods.
Once your grass walk is complete, Grasshopper uploads all your data automatically to GrasslandTools and from there to third-party databases such as PastureBase Ireland, AgriNet and others.

What You Get
Feature Set
Farm Mapping An accurate farm map is the first decision support tool a farm needs. Critical to determining the quantity of grass on a farm, you need to know the productive area of the farm, that is, the area capable of growing grass. Grasshopper has a mapping feature you can use to accurately GPS map your entire farm and up to an additional four farms or blocks. Paddock layouts may change and can be re-mapped at any time with Grasshopper.
Grass Allocation Accurate covers and the correct placement of strip-fencing in the paddock is required from time to time. Using the Allocation feature in the Grasshopper App, enter the number of animals and their daily allocation of grass. The App will show you where to place the strip fence based on the current paddock cover. Grasshopper will accurately indicate where to start and stop your strip fence.
In Real-Time Real-time information on the paddock and the entire grazing platform is critical to your rotation planning as it can vary with paddock productivity over the season. Your grazing platform can be viewed on the phone in the form of a 'wedge' giving you instant information at any time. Wedge information can be shared across a number of work colleagues in real-time. Decision making may be shared, for example, with remote advisors.
Derogation Compliance Farmers are required to conduct 20 grass measurements annually and upload the data to Pasture Base Ireland from February 2020. Grasshopper makes the job of compliance with these new rules easy. Collecting accurate grass data and uploading it to GrasslandTools or PBI automatically is necessary for compliance. A big benefit of your GrasslandTools account is the ability to print derogation reports.

Can Grasshopper be used to measure the cover of a section of a paddock?
Grasshopper takes a series of samples across the paddock being surveyed. Each sample is tagged with a date, time (to the second) and it's geo-location. The sample is the compressed height of the grass at the sample point. When reviewing sample data it is possible to review any single sample, a small area, or the paddock as a whole via the .csv file.
Can I manage my rotations with Grasshopper?
Grassland management is up to you as farm manager. Grasshopper will provide your weekly grass walk data in the form of a grass wedge, using either our online decision support tool GrasslandTools or a third-party online service such as PastureBase.
Can I map and use out blocks?
Yes. Each block is considered a grazing platform in its own right. Contact PastureBase or AgriNet to determine how you should treat different grazing platforms if you are using the same herd number or code.
Can more than one user operate Grasshopper?
Yes. As many users as the farmer would like can sync the farm on their own phone by using the unique farm ID. Any phone can be synced on the farm automatically.
How often should I recharge Grasshopper?
Grasshopper has up to 6 hrs battery life. Grasshopper has a smart charger meaning you can’t do any damage by leaving it plugged in when not in use.
Where do I find my Grasshopper ID?
Your Grasshopper ID can be found on the product label on the underside of the sensor unit, or on your warranty card.
What do the LED's on a Grasshopper mean?
Green flash – GPS acquired, ready for use.
Red – unit waiting for GPS or calibration on older models.
Blue – unit is charging. Goes out when fully charged.
Can I use Grasshopper in any country?
Yes. Grasshopper may be used worldwide.
Can I use Grasshopper to revise my paddock sizes?
Yes. Using the allocation option in 'area' mode you can accurately re-organise your paddock layouts.
Will The Grasshopper App Work With Any Phone?
Any Apple or Android smartphone purchased within the last 5 years should be sufficient. For older models, results may vary. If you are unsure whether your phone is compatible, please get in touch with our support team.
How Do I Find The App?
For iPhone users: you can find the Grasshopper app on the iOS App Store by searching for 'Grasshopper – made to measure'. For Android users (Samsung, Xiomi, Google, OnePlus, Motorola etc): You can find the app on the Play Store by searching for 'Grasshopper – measure to manage'.
Does Grasshopper Need Network/Data Coverage?
The Grasshopper app is designed to work without data network coverage. It does not rely on any external network for mapping. However, it does require a network connection to upload data to an external database such as PastureBase or AgriNet.
Can I See Cover Results On The Grass Walk?
As you measure each paddock the results will pop up on your screen in real-time. These include compressed sward height (CSH)(mm), average CSH(mm), cover (kg/DM/ha), cover within the paddock, growth rate since last measurement (kg/day/ha). At the end of the walk you have the option to look at the results, including the grass wedge, total farm cover and average farm cover in the wedge tab at the bottom of the home screen.
Can I See The Results For Each Paddock?
You can view your paddock results by selecting ‘Paddocks’ from the home screen. This feature is unavailable while the Grasshopper is in use on a grass walk.
