Hustler Super-Z Deck Cover Replacement Knob

Lost the knob on your Hustler Super-Z deck cover? That little plastic piece does more than you'd think — without it, the cover rattles, sits loose, and becomes a proper annoyance every time you fire up the mower. This replacement knob snaps in with a standard 5/16 nut and gets you back to a clean, secure fit without hunting down an overpriced OEM part or waiting weeks for a dealer order.

How it fits

The knob is built around a press-fit 5/16 nut that seats firmly inside the body. Once the nut is in place, you thread it straight onto the existing bolt on your deck cover — no tools required beyond what you already have in the garage. It fits the Hustler Super-Z and is likely compatible with a range of similar ZTR mower models and brands that use the same bolt size.

A plug is included to close off the nut recess once everything is assembled, giving the finished knob a clean look and preventing debris from packing in around the nut over time.

What you get

• One replacement deck cover knob, ready to install
• Plug included to seal the nut recess
• Accepts a standard 5/16 nut (not included)
• Compatible with Hustler Super-Z and likely many other ZTR mower models
• No drilling, cutting, or modification needed
• Compact and lightweight — won't affect deck balance or cover fit

The everyday wins

It's a small part, but a missing or cracked deck cover knob is the kind of thing that nags at you every single mowing session. This one solves it permanently. Reuse the nut from your old knob if it's still in good shape, press it in, thread it on, and you're done. Your deck cover sits flush and secure the way it should — and you stop thinking about it entirely, which is exactly what a good replacement part should do.
