Thank you, I’ll try it. There are so many different wiper motors out there that fit various tractors. I’m gonna wait till warmer weather. Take mine out. Take all the measurements and then go find one. John Deere wants $400 for the motor and arm. By the way, that number is the Curtis cab number. There are no part numbers anywhere that I can see on the wiper motor which I’m sure is purposely done.Is that picture of the wiper motor? (Is that the OEM part number)?
If you can see the motor, do an internet search for "curtis 1jd4120as wiper motor".
I looked on Amazon and a couple motors showed up but I'd look at the pics and compare to what you currently have installed.
