How to Install a Drive Belt on a Wheel Horse 416 Mower

Updated February 21, 2017

As the mowing seasons go by, the invaluable drive belt on your Toro 416 riding mower or wheel horse can grow to be brittle and frayed. A clear-cut sign that your drive belt has broken down and the blades have stopped spinning is that when you look over the area of yard you just mowed, you see that the grass is not at all shorter. Replacing the non-working drive belt can be completed without the aid of a professional in just under a half-hour.

Park your Toro 416 on a level surface. Disengage the spark plug wire and remove your ignition key.

Grip the deck lever. On all Toro 400 series mowers, the deck lever is situated directly to the right of the driver's seat. Ease the deck lever down until it arrives at the lowest level. Use an adjustable wrench to unscrew the bolts securing the belt guard. Lift away the belt guard, situated in the centre of the mower deck.

Slide beneath your Toro 416 and manually yank the broken drive belt away from the engine pulley. Continue peeling the bad belt until it is free from the stationary idler pulley. Pry the last sector of the defunct belt from the clutch idler pulley. These two idler pulleys are found directly beside the engine pulley.

Attach a replacement Toro 416 drive belt to the notches along the surface of the clutch idler pulley. Manually turn the clutch idler pulley one half rotation. Fasten the next section of the new drive belt to the grooves on the surface of the stationary idler pulley. Install the final segment of the new belt to the engine pulley. The replacement belt should be tight with no slack. Reattach your belt guard.

Seize the Toro 416 deck lever and guide it up to your desired height for mowing. Start your Toro and inspect for correct operation.
