How to sharpen" bush hog" or rotary cutter blades and properly inspect and maintain

What happens here

After sharpening, carefully place the blade back onto the pin, ensuring it's oriented correctly (as noted during removal). Slide the sleeve over the pin, then replace the retaining clip and tighten the retaining bolt with the socket wrench. The host warns that some manipulation with a small hammer might be needed for a tight fit. Following blade reassembly, perform regular maintenance: lubricate the bush hog's wheel and the PTO (Power Take-Off) shaft knuckle. Locate the grease fittings (zerk fittings) on the wheel and inside the PTO shaft cover. Use a grease gun to apply grease until you hear a 'pop' or see old grease being pushed out, indicating proper lubrication. Finally, check all bolts to ensure they are tight and snug.

Goal: Securely reattach the sharpened blade and perform general lubrication on the bush hog.
