The Husqvarna riding mower offers a convenient way to tend a large lawn. It comes with many features, including articulated steering, and offers both efficiency and comfort. However, there are times when the mover needs replacement parts, such as a drive belt. Fortunately, it is relatively straightforward to replace the drive belt on a Husqvarna riding mower. It is important that gardeners take note of the existing configuration of the belt so that they can carry out a correct installation.
Understand Drive Belt Faults
The drive belt on a Husqvarna riding mower can fail in several ways. Breaks can appear in the rubber belt, causing it to lose tension on the pulleys. Eventually, the breaks can cause the belt to snap entirely. The belt can also suffer wear and tear along the edges. This creates an uneven belt that slips because it no longer offers a tight fit, so it fails to turn when the pulley spins. One of the signs that there is a fault with the drive belt is the blades stop spinning when the gardener attempts to cut grass.
Replacing the Drive Belt on a Husqvarna Riding Mower
The Husqvarna riding mower features a cutting deck that offers protection from the blades for both the gardener and the mower's engine. The deck sits under the main body of the mower and it is the component that holds the drive belt. Before removing the drive belt, it is necessary to slide the deck from under the riding mower.
Remove the Cutting Deck
Metal pins secure the deck to the lawn mower and hold the shafts in place. Grip the pins firmly using a pair of pliers and pull backward in a straight line to remove the pins. Push or pull the ends of the shafts to disengage them from their holes. Pull out the bar above the drive belt. The drive belt should be fairly slack, so just push it away from the engine pulley. Once the deck is completely disconnected, slide it out from under the riding mower.
Make a Note of the Configuration of the Drive Belt
Many Husqvarna riding mowers have a sticker on the deck near the pulleys featuring a diagram of the drive belt configuration. If this is not present, take a photo
of the old drive belt before removing it from the pulleys. This makes it easier to install the new drive belt in the correct configuration.
Remove the Drive Belt
A metal bar joins the two center pulleys, so undo one side to allow access to the Husqvarna drive belt. Hold one of the bottom nuts of the assembly to stop it from rotating and use a socket wrench to undo the top nut. Remove the carriage bolt, and then lift the metal bar and rotate it out of the way. The drive belt is now free, so simply pull it away from the pulleys.
Install the Drive Belt
Follow the pattern in the diagram or photo of the drive belt configuration and ensure the placement of the new belt is identical to this position on the pulleys. Rotate the metal bar back into position on the center pulleys, replace the carriage bolt, and finger tighten the nuts before making sure they are secure using the socket wrench. Slide the deck back under the riding mower. Realign any bars and shafts, adjusting the deck as necessary. Replace the pins by pushing them into place. Grab the drive belt and pull it around the engine pulley.
Test the Belt
Engage the drive belt by pulling the lever on the lawn mower all the way up to its maximum position and make sure it stays in place. If the belt is too tight, the lever cannot reach its full position. In this case, adjust the shaft on the deck that connects to the lever by moving the nut upward. If the belt is too loose, the blades stop turning when trying to cut grass. If this happens, move the nut on the shaft downward.
