I have a Deere 457 standard and it has both square and round pickup teeth. I noticed that I am missing a few and before I buy any I wanted to know if one was better than the other?
If I remember correctly, the square are stronger, but they only go on the outside rows of the pickup. it's been almost a year since I looked at a baler pickup.
I have a 2002 model 567 Megawide it originally came with all the standard teeth in the center being round. For a number of years the replacement teeth I bought from Deere were also round but a few years ago they switched them to square and said they were stronger and the round ones were no longer available.
