A new dual metering tube system and a blockage monitoring device have been introduced to Australia by AJS Machinery, the local agent for US-based Surefire Ag.

The LiquiShift dual metering tube system replaces a single section valve on a regular seeder or vegetable planter with two valves, while still delivering to a single row or section.

AJS says that with two valves, the system can sense the pressure of the fertiliser independent of any other control system, and can also open and close additional metering tubes of a different size to maintain the required pressure and flow for a given speed.

"It is easily described as a three-tier system: one valve opens to deliver fertiliser via one size metering tube; then, as the flow rate requirement increases, the second valve opens," AJS says.

"This technology allows operators to vary their seeding speed significantly and to have greater on-the-go rate changes than they could before, improving accuracy and timeliness of application.

"The system can operate autonomously and independently so there is no need for the operator to change any settings or hardware – even when going from one crop type to another, with significantly varied rates," AJS adds.

The other new attachment, the Sentinel, provides row-by-row in-cab ISOBUS monitoring of fertiliser flow rates, as well as rate control, section control, and Rx mapping on seeders and planters.

Surefire is also the company behind the Quickdraw automated chemical batching station for sprayers, named the agribusiness innovation of the year in 2019 at the Wimmera Machinery Field Days.

The Quickdraw can mix up to six different chemicals into one batch – keeping logs of the exact amounts as well as considering the acreage to cover, the preferred litres per application rate and the total batch size.

The new QuickDraw 3000, released here this year, offers auto-calibration of the electro-magnetic carrier flow meter, product hose rinse on all models and a four product carrier blending option for on-farm blending, as well as a 10-inch display screen the company says is six times brighter than before.

AJS is also offering the smaller QuickDraw Lite, with three automatic and three manual product valves, for a starting price of $22,600 + GST.
