Where You Should Find The Best Price For Black And Decker Twin Blade Mower Parts For Your Second Hand Mower Or Tractor

Sometimes, a riding lawn tractor with old tractor tires or mower’s blades can become unbalanced, bent, or lifeless, and will need either reconditioning or replacement. It is advised that upkeep be performed on the blades at least twice yearly. To care for a riding lawn mower’s blades, follow the steps listed below.

NOTE : black and decker twin blade mower parts materials are prepared for use by trained technicians who are experienced in the service and repair of apparatus of the kind described in this publication, and are not intended for use by untrained or green people. Such people should seek the help of a service technician or dealer.

Preparation:

As with many projects, think safety first. Always wear heavy leather gloves and safety glasses / goggles for protection and always disconnect both the battery ground wire from the negative battery terminal and the spark plug wire from the spark plug. If the unit is provided with a twin cylinder engine, remove each of the spark plug wires from the spark plugs.

Removing the Blades:

Most riding lawn mowers have removable blades. To reach the riding lawn mower’s blades, take away the deck before performing maintenance. Don’t tip the riding lawn mower on its side. This may end up in heavy damage to the unit. Take away the riding lawn tractor’s blades by turning the blade bolt or nut counter-clockwise with the standard long-handled wrench. Don’t be confounded if the blade bolt or nut is tricky to remove due to standard corrosion, mud increase and initial torque setting of 70 to 100 ft. Lbs.

Sharpening the Blades:

Sharpen the riding lawn tractor blades by employing a tool, like a hand file, which is designed to be used on hardened metal. It’s not imperative the blade be as sharp as a knife. An edge at approximately a 45 degree angle will be acceptable. Almost all of the wear will be round the blade tip. Focus on this area. If the blade is seriously worn or gouged beyond reconditioning, replace the blade. Follow the above procedures for all the blades.

Balancing your Blades:

Before installing a new or sharpened blade, it’s important the blade is balanced. If a blade isn’t balanced properly, it will rattle and vibrate. This will damage other components on the riding lawn mower. Blade balancing tools can be purchased at a local appliance store for a reasonable price. Clean all mud and debris from the blade. If the blade is not totally cleaned it will affect the balancing of the blade.

There are 2 procedures for checking the balance of a blade that we call out in this publication. The first is when using the vertical test strategy, the free hanging blade will revolve on its own, heavy side downward. The horizontal test methodology is the second ; this is when one side of the blade begins to drop towards the table top. The side that drops to the table top or revolves downward is the heavier side, and wants further sharpening or material removed to balance out the blade. After sharpening, test the blade balance again, and repeat till the blade is balanced. Follow the above procedures for the remaining blades.

Installing the Blades:

Once the blade has been sharpened and balanced, re-install it with the proper alignment. If using an OEM blade, the word “Bottom” is stamped on the blade for the side that should face the ground. If the word “Bottom” isn’t present, be sure to install the blade with the raised tips toward the head of the deck. The blade bolt or nut should be tightened properly using seventy to 100 ft. Lbs. Of torque.
