I just upgraded to a Stihl Kombi 131 and it’s a beast. Got it mainly to run attachments and brush hog tall weeds and grass. I even use it to trim up regular every day stuff it’s just heavy. My question is can I use other attachments than Stihl? Been seeing videos where dudes are running ryobi and the generic trimmer plus attachments. I know you can buy the little insert sleeves from Stihl, has anyone ever had good luck running these or modifying them to work as factory? The idea of paying 300$ for an attachment I won’t use but a few times a year just kills me.
