Know exactly how much grass you have.
GrasslandTools is home base. Walk the farm with a Grasshopper and the wedge, the grazing plan and the paddock map draw themselves. Your WeighRite sessions and every e-gate report in too.

Every paddock, mapped and measured
Grasshopper measures compressed sward height to the millimetre as you walk, and you decide the moment each drop is taken. By the time you're back at the yard the wedge is drawn, the map is shaded, and the grazing plan knows which paddock is next.

Grasshopper ist das genaueste Messsystem für den Grasaufwuchs, das derzeit auf dem Markt erhältlich ist. Über drei Jahre mit dem Moorepark Grassland Research Centre entwickelt und validiert.
Sobald die Messung gespeichert ist, wird aus dem Aufwuchs ein Grass Wedge: Bedarfslinie, durchschnittlicher Aufwuchs, Überschuss und Defizit, laufend neu berechnet.
GPS-Erkennung der Koppeln und farbige Aufwuchskarten. Zeichnen Sie den Betrieb einmal im Karteneditor und teilen, verbinden oder säen Sie nach, wenn sich etwas ändert – die Historie bleibt erhalten.
Die 20 Messungen pro Jahr, die eine Derogation verlangt, erfasst und datiert – der Bericht steht direkt in Ihrem Dashboard bereit, wenn Sie ihn brauchen.
Smart animal weighing · works with your own bars · live results on your phoneWeights that tell you something
WeighRite turns your phone into the weigh-head display and works with the bars and crush you already own. Sessions arrive here as progression, daily gain and cohort breakdowns you can act on.
Der EID-Eingang erkennt jedes Tier, sobald es auf die Waage tritt. Herdendaten kommen von ICBF, die Ergebnisse gehen im Hintergrund zurück. Nichts muss abgetippt oder von Hand eingegeben werden.
Automatisch sortieren nach Gewicht, Geburtsdatum, Rasse, Betriebszweig oder Zieldatum – und Körperkondition und Fügsamkeit gleich mit dem Gewicht erfassen.
Verfolgen Sie das Wachstum eines Tieres zwischen den Wiegungen oder vergleichen Sie Kohorten, sehen Sie die besten Tiere und welche zurückfallen.
Solar gate release · easy to install and move · activate from anywhereThe gate opens without you
e-gate is a solar-powered remote gate release that attaches to your fence post. No wiring, no new gate. Trigger it from your phone, set it on a timer, or arm it to let the herd out when the rain starts. A dairy farmer could save 200-300 labour hours a year bringing the cows into the parlour.

Ein Tippen in der App öffnet den Durchgang, wo auch immer Sie sind. Die Kühe kommen in ihrem eigenen Tempo – das schont die Klauen mehr als Treiben.
Stellen Sie im Frühjahr einen Drei-Stunden-Rhythmus für die Beweidung ein, planen Sie eine Öffnung wie einen Wecker, oder verbinden Sie eine passende Wetterstation und lassen Sie das Tor bei einsetzendem Regen selbst öffnen.
Verriegelung, Zaun, Batterie, Signal, Position und Alarme werden regelmäßig gemeldet – so erfahren Sie von einer schwachen Batterie oder einem stromlosen Zaun, bevor es zum Problem wird.
The paperwork, handled
The parts of farm management nobody enjoys: the maps for the inspector, the fertiliser record, the annual summary. All generated from data you already entered.
PDF paddock maps with your own branding, you can print these to hand out, or get a whiteboard made for the parlour.
Plan the rotation ahead, with entry and exit covers and days-grazing per paddock.
Season summaries and growth reports as PDF or Excel, ready to send on.
Printable proof of 20 required grass measurements for derogation compliance, produced from your own paddock and herd data.
Log spreading by paddock and keep the year's nutrient record in one place.
Close paddocks, plan cuts and track yields without breaking the grazing figures.
Store soil samples against the paddock they came from, so the map shows the whole picture.
The Grasshopper and WeighRite apps work on a phone, in the rain, out of signal, and sync when you get back to it.
Give an advisor or contractor access to a farm without handing over your login.
Three steps, once a week
- 1
Walk the farm
Take the Grasshopper out to measure your grazing platform. GPS knows which paddock you're standing in. Drop the plate every few steps as you go.
- 2
Let it do the sums
Drops become a cover, a wedge, an average, a growth rate and a grazing planner, the moment the walk is saved.
- 3
Act on it
Move the herd, allocate a strip fence, close a paddock for silage, then let the figures go on to PastureBase, AgriNet or whoever needs them.
It plays nicely with the rest of your records
Measure once and file it everywhere. Covers and weights recorded here go out to the national and commercial databases you already report to.
Aufwüchse gehen direkt an PastureBase Ireland.
Grasmessungen werden in Ihr AgriNet-Konto hochgeladen.
WeighRite holt Ihre Herde von ICBF und meldet die Ergebnisse zurück.
