Excavator

Sheet metal styling for an excavator

A vehicle comprising a hydraulic fluid reservoir, a hydraulic fluid pump, a hydraulic filter, a sensor, and a vehicle control unit. The hydraulic fluid reservoir may have a bottom portion filled with hydraulic fluid and a top portion filled with air. The hydraulic fluid pump may be hydraulically coupled to the hydraulic fluid reservoir so as to draw hydraulic fluid from the hydraulic fluid reservoir. The hydraulic filter may be hydraulically coupled to the hydraulic fluid reservoir so as to filter debris from the hydraulic fluid entering the hydraulic fluid reservoir. The sensor may be in communication with the vehicle control unit where the sensor is configured to measure a variable indicative of a failure status of the hydraulic filter and communicate the variable to the vehicle control unit. The vehicle control unit may be configured to derate the hydraulic fluid pump to a first degree when the variable indicative of the failure status of the hydraulic filter is above a first threshold and configured to derate the hydraulic fluid pump to a second degree when the variable indicative of the failure status of the hydraulic filter is above a second threshold.

Apparatus and method for a hydraulic system

A hydraulic management system and method are provided that account for auxiliary work tool usage. The hydraulic management system automatically calculates an effective use time of a hydraulic element, such as a hydraulic fluid or hydraulic filters, by multiplying work tool usage by a desired gain factor, where the gain factor may exceed 1 for auxiliary work tools.
