Earlier this week, I saw the old post in the 'fabrication' topic regarding armrests on a L3301. Seemed like a good idea since I really like the armrests on my BX.
I knew the seat on my L3301 was made by milsco. After a little research, I found out my local Grasshopper dealer (sells other brands too) actually has armrests for this milsco seat in stock. I stopped in on my way home from work yesterday and picked up a set for $86.00 plus tax.
Got them mounted this afternoon. Way more comfy now. Don't know why I didn't do this five years ago!
First picture shows speed nuts clipped onto the seat bucket.
Second picture shows bracket mounted.
The other pictures show rest mounted as well as proximity to controls.
