How to Change Scag Mower Blades

Whether your Scag mower has two, three or four blades, the process of changing them is simple. There’s no need to pay a mechanic to do the job. You can easily do it yourself. Very little time is necessary, and the only tool you need is an impact wrench. Worn mower blades leave uneven cuts. To ascertain whether or not your mower blades need to be replaced, examine the outermost cutting edge of each blade. If the edge is so thin that it is curling, or if grooves appear in the metal appear, the blade is no longer good.

Raise the mower deck to the highest position.

Remove each belt cover.

Engage the brakes, and elevate the mower deck using a floor jack.

Locate the hex nuts attached to the bolt that goes through the spindle assembly to each blade (amounts depend on how many blades your machine has).

Remove the hex nuts using an impact wrench with the proper sized socket attached.

Push the bolt through the spindle assembly, and remove the spacer, the blade and the washer.

Replace the washer onto the bolt, then the new blade and the spacer.

Feed the threaded part of the bolt back up through the spindle assembly.

Thread the hex nut onto the bolt, and tighten with the impact wrench.

Lower the mower off the floor jack, and reattach the belt covers.

Change 40-inch Huskee Lawn Mower Blades

Park the Huskee riding mower on a flat and level surface for changing the blades. Put on gloves to protect your hands while working. Place a wood block under the mowing deck against the baffle. Mark the bottom of the blade with a permanent marker to help when installing the replacement blade. Locate the bolt in the center of the mower blade that holds the washer and blade in place on the mower spindle. Use an adjustable wrench to loosen and remove the bolt. Purchase suitable replacement blades for the Huskee mower from a mower repair shop or hardware store. Make sure the side of the blade with the mark is facing the bolt head. Finish tightening the bolt with the adjustable wrench.

Tip

Spraying the hex nuts with lubricant before removing them will make the job easier. If you don't own a floor jack, elevate the mower by driving up a ramp.
