The 5105.4G uses a 40km/h wet clutch semi powershift transmission. The 5 synchronised gears, 4 work ranges (slow, fast, underdrive and supercreep), and 2 Powershifts give the operator the wide variety of options capable of fulfilling all work speed requirements. A press of the button on the gear lever and without using the clutch pedal, the Hi-Lo can reduce (or increase) the gear speed when loaded by approximately 16%. This option is particularly useful when working on a very uneven terrain
The shuttle control is hydraulically adjusted with a 5-position modulation control; this option is useful in terms of productivity and safety, especially if the machine frequently operates in a restricted area with a front loader. In addition, the hydraulic shuttle is equipped with two sets of multi-disc, oil-immersed “Long life” clutches to reverse up to 13 km/h, even when loaded. The 5105.4G is also equipped with Stop&Go, which allows you to stop and restart the tractor without having to use the clutch pedal.
To couple equipment efficiently, the PTO on the 5G Series has 4 standard speeds (540/540ECO/1000/1000ECO), with electrohydraulic engagement. An optional front PTO which operates at the standard 1000 rpm can be fitted with the front hitch.
The PTO is simple and logical to handle, thanks to the electro-hydraulic controls on the right-hand console and on the rear fenders. The engine revs are shown on the instrument panel which moves with the steering wheel adjustment to ensure clear unobstructed view of the operating speeds. In the versions with an electronically controlled hitch, the Auto PTO function allows you to automatically stop and start the rear PTO in conjunction with raising or lowering the rear linkage.
