Optimize tractor powertrain systems with<br />
hydraulic cartridge valves and manifolds with<br />
programmable controllers.<br />
Synchronize control of transmission clutch, PTO, and fan<br />
with the <strong>HydraForce</strong> CoreTek controller. Its programming<br />
software is available as a free download from the<br />
<strong>HydraForce</strong> web site. The CoreTek controller (circuit<br />
at right) can synchronize proportional valves, such as<br />
the TS98-T34, to regulate <strong>for</strong>ward, reverse and multiple<br />
clutch actuation with smooth and accurate control<br />
of pressure. Clutch fill characteristics can be customprogrammed.<br />
PTO control can be accomplished with the<br />
EHPR98-T38 proportional valve, and fan control with the<br />
TS10-27 pressure regulator valve.<br />

Use a Priority Flow Control circuit to give priority to<br />
steering and brakes then allow hydraulic flow <strong>for</strong> other<br />
tractor functions, such as plowing, planting, harvesting,<br />
loading, or suspension control.<br />

Fan<br />
Quiet down that fan . . .<br />
Fan drives controlled by hydraulic cartridge valves are<br />
quieter and run on less horsepower than mechanical fan<br />
drives, providing greater fuel economy <strong>for</strong> tractors.<br />
Control valves with multiple temperature inputs can be<br />
used to provide variable fan speed control depending on<br />
air temperature, load, and cooling requirements. If the<br />
radiator gets clogged, two-position, four-way solenoid<br />
valves can automatically reverse fan direction.<br />
Electronic control of the hydraulic cooling system can be<br />
achieved using either an EFDR1 programmable valve<br />
driver or a CoreTek controller (ECU).<br />
