Lifting Deck and Loosening Pulleys

What happens here

The presenter first shows the new spindle, emphasizing its shaft and keyway, which will connect to a pulley. He states the need to remove the pulley to replace the spindle. He then uses the Ventrac's hydraulic system to lift the entire mower deck into its maintenance position. Next, he identifies the belt tensioner, releases the tension by sliding a pin, and uses an impact driver to attempt to loosen the nuts holding the pulleys. He finds the nuts are extremely tight and mentions needing to put the blade back on and lower the deck to stabilize it while trying to loosen the top pulley.

Goal: Access the pulleys above the spindle and begin loosening them
