Hyflo folds seed planter wings
2nd Quarter 2016
Hydraulic systems & components
Hyflo Southern Africa, a BMG Group company, was commissioned by Theebo Tech to engineer the electrical and hydraulic systems for the Equalizer Maximus Wide Span planter. This planter is the biggest seed planter manufactured in South Africa and has two 12 metre wings, allowing up to 24 rows to be planted in a single run. With such a large wing span, the planter would not fit through farm gates, nor be able to drive down farm roads. Hyflo was asked to provide an automated solution to fold the planter’s wing during transportation.
Hyflo worked closely with Theebo Tech in the initial design stage to ensure the hydraulic system would be able to fold the massive 12 metre, 3 ton wings. However, due to the complexity of the hydraulic folding requirements, it was clear that mechanical control would not be feasible. Hyflo’s Mechatronic department was tasked with designing an automated solution.
The brain behind the control of the planter is the HydraForce Electronic Control Unit (ECU), an IP67 PLC purpose built for the control of mobile hydraulics. The ECU allows the entire planter to be folded and unfolded from the comfort of the tractor’s cab. To achieve this, the ECU relies on 43 I/Os which include position sensors, pressure switches, inclinometer, control interface and 13 solenoid valves. Hyflo and Theebo Tech were able to complete four Maximus planters in just over two months, showing their combined capabilities as leaders in the industry.
