Round Baler Moisture Disc


Harvest Tec  Precision Moisture Sensor systems are the core component allowing the owner to both maximise the output of their baler, but also the quality of the bale they produce

These systems are available for round, conventional and square balers

Moisture systems availability for round balers

  • H2O Precision Moisture Sensor
  • 300 series Moisture Monitor
  • 600 series Moisture Pro


Our precision moisture meters use either electrical conductivity (round, conventional and large square) or microwaves (large square option) taking measurements many times per second

They measure not only the area of the bale in contact with the sensor, but also through the profile of the bale as it is produced by the baler. They measure both leaf moisture and moisture locked deep inside the plant stems that is often invisible to hand probes and inferior pad type moisture systems


These systems give the operator real time information as they bale, thus helping to improve bale quality and baling when the conditions are suitable. When conditions are not ideal they provide consistently accurate information to our automatic applicators, which allow for maximum baler output by increasing the operating window and reducing cost with longer day time baling and maximising efficiency.


Harvest Tec 300 Series Automatic Applicator

300 Series Automatic Modular Applicator system suitable for round and conventional balers

As with all our Automatic Applicators, the 300 Series relies on highly accurate sensing discs on either side of the round bale chamber.

Instant response:  The 300 Series Automatic Applicator features an improved flowmeter working through a single bypass pump, which supplies a constant pressure to a pulsating solenoid valve. This is capable of covering a wide range of application rates, but also provides improved response to variations in moisture and an instant on/off. This has the added benefit of being simple to service and operate. It comes as standard with a Bluetooth receiver to enable the system to be controlled using either an iPad or iPad Mini (not supplied) 

Harvest Tec 300 Series Moisture Monitor

The HayBoss 300 Series Moisture Monitor is ideal for operators of round and conventional balers who want a straight-forward precision moisture monitor.
The moisture sensors are accurate to within -/+1% and take readings nine times a second, which are averaged every three seconds.
Moisture range round balers: 8-60%. 
The 300 Series offers a premium specification for ease of use and simplicity.
It comes as standard with a Bluetooth receiver to enable the system to be controlled using either an iPad or iPad Mini (not supplied)


Harvest Tec  600 Series Automatic Applicators for round balers

The latest Harvest Tec  600 series applicators for round balers


Harvest Tec  Moisture Pro

Moisture Pro is a Moisture monitoring system that will measure the moisture in the bale from 8-60%.  The Moisture Pro is readily able to accept any of the following HayBoss modules depending on your individual requirements. Job records are fully downloadable with Moisture Pro.  


Harvest Tec Automatic Applicator

The high precision Harvest Tec Applicator can be ordered as a complete unit with moisture meter included. Adding the applicator module to your moisture meter allows you to automatically apply the correct amount of Baler’s Choice preservative on those higher moisture bales. The system will not only keep track of the moisture levels of the bales, but will also display and record the amount of preservative being applied and also how much was used per individual bale. HayBoss is automatically paused, using sensors on the pickup, when no crop is entering the baler.

Harvest Tec High Output Electronic Manual Applicator 100 Series for Round Balers

This is a manually operated system for silage inoculants and acid additives. The rate is manually controlled and so is designed for fixed rate application of silage and haylage products.

Application of inoculants and acids

The Electronic Manual High Output applicator is ideally suited for use with modern, high output fixed and variable chamber round balers and large square balers

Applies a constant rate as set by the operator

Application rate can be adjusted by selecting different nozzles and pressure

Moisture readings determined using either a hand held probe or ideally for optimum efficiency a 600 Series or 300 Series moisture monitor system

Ideal for applying fixed rates of silage preservative or inoculant

Upgrades available to apply premium buffered propionic acid for hay and straw
