Read articles →This is a narrow how-to on recharging AC on a John Deere 5115M, not a general review. It walks through starting the tractor, setting AC to max cold and high blower, locating the low pressure port, attaching a recharge can tool, and reading the gauge to know when the system is properly filled versus low. Useful for owners troubleshooting weak AC, not for buyers researching the tractor overall.

Start the tractor, set AC to max cold and high blower, find the low pressure port, attach a recharge can tool, then squeeze the trigger and oscillate the can between 3 and 12 o'clock until the gauge reads steady.
Leave your finger off the trigger and watch the needle. If the system is low, the needle will drop down, pop back up, and keep moving instead of staying steady in the green.
The transcript shows it under a black cap that you remove before attaching the recharge tool, without giving an exact location description beyond pointing it out on camera.
