Is my old combine supported?

Yes. If your combine has a clean grain elevator, we can install our sensors. We support models from the 1990s and 2000s including John Deere 2200/9000 series, CLAAS Dominator, Mega, and early Lexions.

How hard is the installation?

Installation typically takes 3-4 hours. It requires drilling a small hole in the elevator housing for the sensor and routing power to the cab. No complex hydraulic or CANBUS integration is needed for the basic kit.

Why Retrofit?

New combines cost €300,000+. A retrofit kit costs a fraction of that. If your harvester's mechanicals are sound, there's no need to replace it just to get data.

Our system operates independently of the combine's electronics. We don't need a CANBUS connection to measure yield.

Independent System: Has its own GPS and 4G connection.

Universal Fit: Fits any elevator with a rectangular housing.

Supported Models (Examples)

We have successfully retrofitted hundreds of machines. Common models include:

John Deere: 9000 Series (9500, 9600), W-Series, T-Series, C-Series, older 2000 series
CLAAS: Dominator (all), Mega 204/208/218, Lexion 400/500 series (without Quantimeter)
New Holland: TX 30/60 Series, TF 40/70 Series, older CX/CR models
Case IH: 1600/2100/2300 Axial-Flow series
Massey Ferguson: 30/40 Series, Cerea
Deutz-Fahr: TopLiner, StarLiner
Rostselmash: Don 1500, Acros, Vector
Sampo Rosenlew: 2000/3000 Series

How It Works

1. Optical Sensor

Installed on the clean grain elevator. It measures the volume of grain passing by using light, not impact. This means less wear and no calibration drift.

2. Cloud Processing

Data is sent instantly to the cloud. We combine volume data with GPS speed and position to calculate precise yield per hectare.

3. Live Mapping

You see the map building in real-time on the mobile app. Spot low-yielding areas instantly while you harvest.

Don't harvest blind this season.

Upgrade your combine now and get the data you need to improve next year's crop.
