💙 MULLETS FOR MENTAL HEALTH 💙✂️

The crew at Minesite Mechanical Services have teamed up with the legends at Hydramech Engineering to get behind a bloody good cause this April 🤝🔥

We’re talking mullets for mental health — business up front, party out the back 😅
The boys have fully committed… some look elite, some… questionable 😂 but it’s all for a reason that matters.

This isn’t just about a haircut — it’s about starting conversations, looking out for your mates, and backing mental health awareness 💙
1 in 5 Australians are affected, and every dollar raised goes towards support, education and research.

Massive shoutout to Anna at Outback Barber Shop for getting behind us and bringing these mullets to life ✂️🔥 absolute legend!

If you can, get around it and support the cause 👇

Or better yet — get your crew involved and grow a lid with us 🤝

HYDRAMECH 🤝 MMS 🤝 OUTBACK BARBER SHOP
Let’s get behind it 💪💙

💥 Jumbo rebuilds and repairs done properly — the MMS way. 💥

At Minesite Mechanical Services we don’t just make our machines look good… we make them perform underground where it actually counts.

From full cylinder replacements, hydraulic overhauls, rewiring, valve blocks, booms, feeds and full machine run-ups — every bolt, every hose, every meter of travel matters. ⚙️🔩

Because underground it’s not about the shine…
👉 It’s about reliability.
👉 It’s about accuracy.
👉 It’s about the meters drilled, the meters trammed and the meters that keep a site moving.

Whether it’s a full ground-up jumbo rebuild or hard-hitting breakdown repairs, MMS delivers gear that goes back to work better than it left.

No shortcuts. No guesswork. Just quality workmanship from people who live and breathe underground machinery.

📸 A few snaps from the latest DD421 rebuild in the workshop and another during run-up.

🎥 FROM WORN TO BRAND NEW — 0 HOUR DD421 REBUILD 🔧🔥

From yard to workshop…
From stripped down to bare frame…
Every hose, line, cylinder and cable — rebuilt, replaced, or refinished.
Hydraulics re-run.
New powerpack dropped in.
Fresh paint, precision machining, full system overhaul.

This is what Minesite Mechanical Services does best.
Quality. Detail. Pride in every bolt.
💪 Rebuilding the heartbeat of the mine — one DD421 at a time.
