Hazard
In the braking system of agricultural tractors, the brake valve structure is inadequate, causing residual pressure to remain in the equalizer valve. If operation continues in this condition, the oil temperature rise within the brake valve causes the residual pressure in the equalizer valve to increase, and in the worst case, the brake pedal becomes inoperable.

農耕トラクタの制動装置において、ブレーキバルブの構造が不適切なため、 ①イコライザバルブ内に圧力が残る場合がある。そのため、そのままの状態で使用を続けると、ブレーキバルブ内の油温上昇に伴い、イコライザバルブ内に残った圧力が高くなり、最悪の場合、ブレーキペダルを踏み込めなくなる。
Remedy
Replace the brake valve with a corrective component on all vehicles.
