2-in-1 Blade Set for 42-inch Cutting Decks - 490-110-C108 (2024)

FAQs

How long are the blades on a 42 inch mower deck? ›

For example, this pair of blades meant for a 42" riding mower are 21.5" long each, and this pair of blades meant for a different brand of riding mower are 25.25" long each.

The blade length should be measured diagonally from the opposite tip on each side. A blade that is too long will not fit under the deck while a blade that is too short will leave grass uncut. Finding the right blade length is very important.

How Sharp Should Your Mower Blade Be? Mower blades should be aggressively sharp, but not as sharp as a razor's edge. You should be able to touch the blade with your hand without getting cut. Contrary to popular belief, a lawn mower blade with a razor sharp edge will not cut grass better.

Standard blades, sometimes referred to as 2-in-1 blades, are designed to cut grass and then either discharge or bag the clippings. Standard and high-lift blades are straight and aerodynamic as possible to create a powerful lift that will expel the grass clippings from under the deck.

Blade erosion can happen over time due to yard debris, so be sure sure to inspect the thickness of the mower blade. For the average homeowner, a good rule of thumb is to replace your mower blades annually. Sharpening mower blades on a regular basis will prolong the life of your blades.

If your primary goal is to discharge your clippings, a high-lift blade may be the way to go. However, if you want to use your clippings as a natural fertilizer for your lawn, a mulching blade will be the better choice.

Unlike other mulching blades that push the grass down, the high lift on a gator blade draws the grass up which in turn gives you a clean, even cut. This high lift also makes using Gator Blades in bagging operations a great choice.

Walk behind mower blades should be installed between 38 and 50 foot pounds of torque. Riding mower blades should be installed between 70 and 90 foot pounds of torque.

This can make the knife more difficult to control and may lead to accidental cuts or injuries. Additionally, a blade that is overly sharp may be more likely to break or chip when used on hard materials, such as bone or thick plastic.

Can you sharpen mower blades without removing them? ›

A flat file is an easy tool that'll sharpen a dull blade. Secure the blade secured in a vice. Apply pressure to the file, and run it perpendicular to the edge of the blade to grind down imperfections in the metal and hone the shape of the existing edge.

The notched airfoil blade produces maximum discharge velocity and is ideal for heavy, thick, hard-to-lift grasses. With the high lift of the blade and cutting conditions, the blade takes full advantages of a unit's horsepower.

Recommended Mowing Height

The ideal mowing height for most lawns is between 3.5 to 4 inches. The benefits of mowing tall are numerous. Roots will grow deeper, improving drought tolerance. Tall turf provides better shade for the root system, conserving water, and blocking the growth of unwanted weeds.

Place the mower on a flat surface, like the sidewalk or driveway. Use a ruler to measure the distance from the sidewalk to the bottom of the mower. Use the levers on the wheels to adjust the height of the deck to 2.5 to 3 inches.
