Hi-Lift Blade

Lowered the mower deck to access the idler pulley. I used the ratcheting strap to remove the tension spring to release V-belt tension. Removed old idler pulley, cleaned the area, then put the new one in place. Installed the bolt and tightened. Used the ratchet strap the reinstall the V-belt tension spring.
Raised the deck and drove the mower onto ramps. Use a short piece of 2x4 to hold blade still when I used a socket to remove the blade bolts. Cleaned the bolts and area around the spindles. Installed the new blades and bolted them in. Used the 2x4 to hold the blades when I tightened the bolts.
The other pulley and V-belt are spares.
Easy job if you have the tools.

Removed Nuts and Bolts from Blades and Removed Worn Out Blades with New Blades . Reinstalled Retaining Bolts/Nuts and Torque them Down. Cuts Great Now !!
