Tractors and farming implements: choice of hydraulic fluid
 
Autumn has arrived and the field work associated with this season has begun. Tractors will begin to plough the farmland in the next few weeks and producers will be vibrating their olive trees to harvest their fruit a couple of months later.
 
There is a wide range of implements for tractors designed for their hydraulic power. They are normally attached to the rear power take-off (three-point hitch system) and ensure greater control over these implements, a more effective use of power than mechanical systems, in addition to facilitating the transportation of implements when they are no longer being used.
 
All this farming activity has one thing in common in the tractor: the hydraulic system. When faced with the choice of hydraulic fluid for running in a tractor, we find the information provided by the manufacturer of the equipment is generally scarce or limited to a list of commercial product brands, without any details of the characteristics, specifications and properties of the fluid.
 
Choosing the right hydraulic fluid based on its viscosity (suitable for the operating temperatures of the equipment) and its degree of cleanliness will reduce consumption and increase the machine´s reliability and productivity.

Hydraulic fluid for agricultural tractors contains more zinc and phosphorus due to the fact it needs to protect the gears and rear differential, in addition to detergents/dispersants to prevent valves from becoming clogged and a friction modifier to interrupt the lubrication of brake and clutch discs when you need to brake or engage a wet clutch.
 
Viscosity index improvers may also be necessary: additives that are essential to equipment operating in an extremely wide temperature range, as well as pour point improvers for machinery exposed to sub-zero temperatures, as they contain special additives designed to change the viscosity curve and improve the fluidity of the liquid in the cold.
 
OLIPES supplies products such as:
 
Maxitractor 10W30 FS, an UTTO-type multi-purpose lubricating oil specifically designed for hydraulic systems, gearboxes and speed reducers subjected to powerful thermal loads.
 
The standard of quality of API GL-4 ensures it complies with the requirements of the major machinery suppliers such as CASE, New Holland, FEND, John Deree, Kubota... and it contains specific additives to deal with the noise of tractor brakes.
 
Maxifluid POC 55 is a top-quality hydraulic fluid with a high degree of viscosity particularly recommended for equipment subjected to severe conditions and operating in harsh environments with major differences in temperature. It is specifically recommended for olive vibrators.
 
Maxifluid HLP and Maxifluid HV are the professional ranges of hydraulic fluids, available in different ISO grades, adapted to the different specifications of the main manufacturers of agricultural machinery and hydraulic equipment.
