Frequently Asked Questions
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.
OPTIONAL - ARAG RATE CONTROL SYSTEM
Looking for something more advanced we exclusively use ARAG Rate Control Systems these areas capable of
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.
FOLDING TARP & MUDGUARDS STANDARD
Some things should just be standard. So Donder Spreaders include components such as protective tarpaulin cover and mudguards ready for whatever conditions you throw at it.
HYDRAULIC SHUTTER CONTROL
Donder Spreaders are fitted with a two-slide mechanism. One slide covers a portion of the opening to set your rate.
The Second Slide is connected to a double acting hydraulic cylinder which is operated in cab. This allows or cuts flow of material onto the spinners.
