Blade pin and associated cutting element

A mowing apparatus, comprising:

• a cutting element that includes:
• a crossbar that includes:
• an aperture that extends from a first side of the crossbar to a second side of the crossbar;
• and
• an inner wall that abuts the aperture and extends from the first side of the crossbar to the second side of the crossbar along the aperture, wherein a groove is formed in the inner wall between the first side of the crossbar and the second side of the crossbar, and wherein the groove is configured to disperse a lubricant within the aperture;
• and
• a blade pin that couples a blade to the crossbar within the cutting element and extends through the aperture of the crossbar, wherein the blade pin includes:
• a cavity formed within the blade pin;
• a first aperture formed in an end of the blade pin, and wherein the first aperture is connected to the cavity;
• a second aperture formed in a sidewall of the blade pin and configured to allow the lubricant to pass through the second aperture into the groove of the crossbar, wherein the sidewall abuts the inner wall, wherein the second aperture is connected to the cavity, and wherein the second aperture is aligned with the groove of the crossbar;
• and
• a valve located at the first aperture, wherein the valve allows passage of the lubricant into the cavity through the first aperture and prevents passage of the lubricant out of the cavity through the first aperture.
