Frequently Asked Questions
Are these Donder Spreaders easy to calibrate or setup?
Yes, of course, like anything new it’s important to take the time to understand how the machine works and how to calibrate it.
Once you understand the machine generally a full manual calibration for a given product will take 10 minutes.
How accurate are these Spreaders?
If calibrated manually Donder Spreaders are exceptionally accurate.
In our experience if calibrated correctly the spreaders can meter rate within a 2% – 4% of desired rate.
What if I do not want to do a manual calibration?
All Donder Spreaders come with charts for a limited range of products UREA, CAN & DAP.
In our experience you can expect the charts provided with the spreader to be within 7% for desired rate.
Can I get calibration help with from OzValue AG with my Spreader products?
If you are trying to spread a product outside of standard charted products and you don’t want to do a manual calibration contact us and we’ll use our product knowledge and farm experience to assist in recommending a solution and point you in the right direction. Please keep in mind that whenever you change product you must re-calibrate the Spreader to maintain accuracy.
Also, it is important to note that fertilisers, in particular Urea, can vary from supplier to supplier and from load to load so it’s not unusual to have some variation in the rate applied. To be certain of rate the best way to maintain accuracy is to undertake a manual calibration.
ADJUSTABLE WORKING WIDTHS
Donder’s stainless steel spinners are fitted with adjustable vanes, by moving the position of these vanes along the scale we can adjust the desired spread width per product to ensure an even and accurate spread pattern.
STANDARD - EASY RATE ADJUSTMENT
Rate adjustment requires no tools. Simply unlock the handle and slide the gate to the desired position.
Donder Spreaders come standard as a manual set system. This means you determine the desired rate, spread width & Speed.
Provided you maintain your speed and working width your rate will be accurate.
Rate Control – Set rate and electric actuators adjust flow to match speed.
Set the desired Rate on your screen and let the electric actuators open and close to match the flow to your ground speed. So you can spread at a varying range of speeds.
VRA Variable Rate Applications – Prescription maps are loaded into the system to set different rates across a paddock.
ACCURATE METERING AT LOW RATES
The metering orifice is designed so that the first section is able to accurately meter low rates of seed (1 – 10kg/ha) & bait whilst once past the neck of the hole the rate can be increased to allow high rates of granulated fertiliser.
