Avant has developed a new, innovative solution for improving the performance of the drive circuit in Avant loaders. Avant was the first manufacturer to design and utilize the drive circuit system, which has proven to be very effective, offering lots of pushing power and yet enabling a very compact design to the loader, while maintaining an extremely low center of gravity, which is an important part of the great stability of Avant loaders.Through research and development Avant has now improved this system with an innovative way of rethinking. 

The old system resulted in higher fuel consumption with less engine power available for the actual job. In the new system the amount of hydraulic hoses and fittings has been radically reduced and optimized, where the name Optidrive™ derives from as well. The new Optidrive™ is a standard feature first in Avant 700 series, later also in the 500 and 600 series.

There are many benefits to the new Optidrive™, with 10% better performance, reduced power loss in the system, 60% fewer hydraulic connections and far fewer 90-degree angle fittings and T-junction fittings which are less optimal for the hydraulic flow. There are also 20% fewer hoses, and less heat build-up, and in Optidrive™ the amount of flushing oil in the drive motors is five times bigger, compared to the old system, providing a far better cooling of the drive circuit. 

In order to get the best possible grip on all load and terrain situations the parking brake in the Optidrive™ is situated in the rear wheels of the loader. The Optidrive™ has also an effect on the weight and balance of the engine and pump assembly on the loader. The new larger engine mounts reduce vibrations by 50%  on Avant 745 and 750, and by 37 % on Avant 755i and 760i.

The Optidrive™ has the new Parker EO3 fitting system in all of the high-pressure hoses and fittings. This new system has a dial on the fitting, which shows clearly the required torque to which the fitting shall be tightened. Also fewer fittings and fewer hoses equal to less possibility of a hydraulic leak. It also affords for better servicing experience.
