kelly Hi Kelly, we don’t have a mixer that is a Walton’s brand. Are you talking about the Weston 20 or 44 lb meat mixer? The 44 lb can hook up to the Butcher and Pro Series Weston Grinders, they used to say only the #22 or larger but now they say you can do it with any size pro or butcher series.
As for reverse we used to say to hold down the reverse switch the larger pro and butcher series (#22 and up have a reverse) but Weston now says not to run it in reverse for more than a few seconds and that it is designed in such a way that you only need to run it forward. You can check with Weston if you want some verification on that though!
