Filter for a hydraulic circuit of an agricultural system

A hydraulic system for an agricultural system, the hydraulic system comprising:

• a bi-directional fluid line configured to fluidly couple to a hydraulic cylinder of the agricultural system;
• a flow valve disposed on the bi-directional fluid line, wherein the flow valve is configured to move between a first position and a second position, the first position of the flow valve enables a fluid to flow through the bi-directional fluid line in a first direction toward the hydraulic cylinder, and the second position of the flow valve enables the fluid to flow through the bi-directional fluid line in a second direction away from the hydraulic cylinder;
• a bi-directional filter disposed on the bi-directional fluid line, wherein the bi-directional filter comprises:
• a check valve fluid line comprising a check valve configured to block the fluid from flowing through the check valve fluid line in the first direction and to enable the fluid to flow through the check valve fluid line in the second direction;
• and
• a filter fluid line comprising a filter configured to enable the fluid to flow through the filter fluid line in the first direction and the second direction, wherein the filter is configured to block particles that are greater than a threshold size from passing through the filter fluid line, and the filter fluid line is in a parallel flow configuration with respect to the check valve fluid line;
• and
• an additional bi-directional filter disposed on the bi-directional fluid line, wherein the additional bi-directional filter comprises:
• an additional check valve fluid line comprising an additional check valve configured to enable the fluid to flow through the additional check valve fluid line in the first direction and to block the fluid from flowing through the additional check valve fluid line in the second direction;
• and
• an additional filter fluid line comprising an additional filter configured to enable the fluid to flow through the filter fluid line in the first direction and the second direction, wherein the additional filter is configured to block particles greater than an additional threshold size from passing through the additional filter fluid line, and the additional filter fluid line is in a parallel flow configuration with respect to the additional check valve fluid line.

An agricultural system, comprising:

• a first hydraulic circuit;
• a second hydraulic circuit fluidly coupled to the first hydraulic circuit via a hydraulic coupler, wherein the second hydraulic circuit comprises a hydraulic cylinder and a bi-directional filter positioned between the hydraulic coupler and the hydraulic cylinder, and the bi-directional filter comprises:
• a check valve fluid line comprising a check valve configured to block a fluid from flowing through the check valve fluid line in a first direction and to enable the fluid to flow through the check valve fluid line in a second direction, opposite the first direction;
• and
• a filter fluid line comprising a filter configured to enable the fluid to flow through the filter fluid line in the first direction and the second direction, wherein the filter is configured to block particles that are greater than a threshold size from passing through the filter fluid line, and the filter fluid line is in a parallel flow configuration with respect to the check valve fluid line.
