Hello, and thanks for taking a moment to read this post... I have a Kubota B7500 that has a Curtis Cab. Yesterday, the wiper arm complete with its blade came off when I was using it. It appears to be held onto the spindle through a series of interlocking grooves and then tightened with opposing Allen head set screws. I reinstalled it and tightened the set screws but it came off again.... any suggestions? Thanks

Check the allen screws are they stripped?

Take out ALL Allen screws to be sure there are not two stacked ones in each hole. You may be tightening one screw against the other and none against the shaft.

There might be some type of groove or hole for the Allen screw to go into.

Replace all Allen screws with new ones.

Thats all I have for you!

good luck, post back what you did to fix it

You don't want to replace the wiper arm, because a new one is going to cost a king's ransom. The wiper blade can be sourced through NAPA.
