This is a genuine Bachtold spindle shaft for Whipper weed cutters and DR field and brush mowers.
It's the W630B model, and it's the part that holds the blade and lets it spin.

If your mower is vibrating bad, cutting uneven, or the blade won't spin right, this spindle might be the issue.
It's an open-box item, which means it's in excellent condition—like new—but might not have the original packaging.

Perfect if you just need the part and don't care about the box.

It's built to handle the tough stuff, like heavy brush and thick weeds.
Installation means pulling the old spindle and bolting this one in.

If you maintain your own equipment, this is a straightforward fix.

Bachtold made these mowers tough, and having a fresh spindle shaft keeps them running like they should.

Whether you're clearing a field or just keeping the overgrowth down, this shaft keeps your blades spinning true.

Grab it and get back to cutting.
