John Deere 5085 AC recharge

[ufcxl]

Howdy, was planning to juice up my AC with a can of 134a but seems JD's low side port is not a standard size. It's bigger than the quick connect on the hose. Did I just not press hard enough or is there a JD specific size for recharging the AC system.

Were you on the low pressure side of the system?

yes, the larger tube. At least I thought I was. Is the high side port larger?
