A selective filtration system for an operator cab attached to an agricultural vehicle. A HVAC unit supplies conditioned air to an operator space selectively from a CAT 4 filter and a CAT 2 filter. A pressurization blower and two way valve controls flow from the CAT 4 filter to the HVAC unit. Control of flow or isolation of the CAT 2 filter is provided by pressure variations within the system. The CAT 4 filter and CAT 2 filter are isolated from the ambient when they are not in use.

Selective filtration level air treatment system

A selective filtration system for an operator cab attached to an agricultural vehicle. A HVAC unit supplies conditioned air to an operator space selectively from a CAT 4 filter and a CAT 2 filter. A pressurization blower and two way valve controls flow from the CAT 4 filter to the HVAC unit. Control of flow or isolation of the CAT 2 filter is provided by pressure variations within the system. The CAT 4 filter and CAT 2 filter are isolated from the ambient when they are not in use by valves. A calibrated orifice enables positive pressurization to the CAT 2 filter to hold the valves closed.

A device manually controls the acceleration system of a tractor having both a foot pedal accelerator and a hand lever accelerator which can be positioned at different heights above the ground. The acceleration control mechanism includes a first lever hinged at a first end to a fixed pin; a first tie connecting a second end of the first lever to the acceleration system; and a second lever hinged at a first end to the fixed pin. The control mechanism also includes a pedal, which when activated rotates the first lever in a given direction to control the acceleration system by means of the first tie. A third lever is fitted to a fixed structure and can be activated manually to control the acceleration system by rotating the second lever in the aforementioned direction. A second tie connects the third lever to the second lever which rotates the first lever in the aforementioned direction to also control the acceleration system by manually activating the third lever. The acceleration control mechanism further includes a member that is operable to adjust the length of the second tie.
