I found these fluted knobs while looking around online…. They have shifter knobs too.

I found these knobs while looking around online. My order hasn’t been shipped yet, but we’ll see how the process goes as Carr Lane deals primarily with industrial customers. So far so good though. Not to step on anyone’s toes but I thought I’d try them out and see how it goes.

Where will you be using these knobs?

Looks like a Mule Drive Adjuster Knob...

I have used plenty of both Carr Lane & Jergens parts over the years. They can be pricey, but excellent quality.

Wouldn't they have to be drilled and pinned?

Not that that is a problem if you have a drill press.

@rmaynard it’s a replacement for the knob on my mule drive for the 42” RD. The original was long gone and was tightened by using a vice grip. I’m going to have to pin it but it’s supposed to be already tapped 3/8 -16 which was the same as the stock one from the info on here. I have access to a drill press so it shouldn’t be too bad. I figured I’d find something as close as I could get.  
 

@ri702bill That’s what I’m using it for. it looks promising and at roughly 5 bucks a knob before shipping the price wasn’t too bad as well. The ordering process takes some getting used to but I have it figured out now. Good to know about the quality. I figured it being industrial it should be pretty sturdy.

 

We’ll see how it goes. It’s not an exact match but close enough to be usable.

All the mule drive adjusting knobs I have are splined and pinned on.

I assumed they were threaded. There isn’t any splines inside the old brass insert on mine. I thought of tapping the end of the shaft 3/8-16, locktighting, and pinning it if need be.

I need to pull this one off and see what kind of handy work went into making it.

From what I’ve seen on mine, keeping with Wheel Horses philosophy of simplicity. There’s not much to them, the knob is pinned on(at least with mine) to what looks like a fine thread bolt with the head cut off. Simple direct stuff. Easy to fix. If someone had one to take measurements from and the knowledge and access to a machine shop they wouldn’t be super difficult to reproduce.

The brass? insert that is inside the plastic knob, has a splined outside diameter. The brass or whatever its made out off insert inside bore is smooth and pinned on to the mule drive adj. bolt. I should have been more clear in my description. Still don't know how clear this description is and hope I haven't confused you . Bottom line is Ive never seen one that has threads in knob.

Ok, now that you phrased it that way I remember seeing the knurling/splines. Once it gets here I’ll look it over and see if I need to adapt it to work.
