Steep Slope Mowing & Hillside Property Care in Mount Nasura
The "Hills Specialist" approach to firebreaks, slopes, and heavy scrub.
If you live on the hill, you already know the deal: the views are unreal… and the block can be an absolute punish to maintain.
One week the bank looks “fine”, the next it’s knee-high, hiding rocks and branches, and you’re staring at it thinking: How on earth am I meant to mow that without ending up on the news? (Or worse, on my back.)
That’s exactly why we built this service around steep terrain.
ProHill is set up for hillside properties — especially the kind of slopes that make standard contractors politely decline, ghost you after a quote, or quietly tell you their insurance won’t allow it. In Mount Nasura, that’s not an edge case… it’s most of the suburb.
Why steep blocks are a different beast
Steep slope mowing isn’t “normal mowing, but harder.” It’s a different risk profile entirely.
On hillsides, the usual problems stack up fast:
Rollover risk increases the steeper and more uneven the ground is (especially with embankments, long grass hiding hazards, and wet conditions).
Zero-turns and standard ride-ons have limits and can become unstable on slopes and rough terrain.
Hidden obstacles (rocks, holes, sticks) are far more common on banks — and they’re exactly what causes sudden traction loss or a nasty jolt.
So the right question isn’t “Can someone mow it?”
It’s “Can someone mow it safely, cleanly, and without chewing up the hillside?”
That’s what this page is about.
The ProHill approach: “We mow where others won’t”
Most mowing businesses in the area are built for standard suburban blocks. Great for flat lawns. Not great for a hillside verge on a 25–30° gradient.
Our steep block service is built around three principles:
1) Safety-first methods (for you, us, and your property)
We don’t gamble with hills. We plan the job, choose the right method, and work to conditions (slope angle, ground softness, access points, obstacles, weather).
There’s a reason safety regulators keep calling out slope work as a rollover risk for ride-on mowers.
2) The right gear for steep slopes
Steep properties need purpose-built solutions — not “she’ll be right” improvisation.
Remote-controlled slope mowers are specifically designed for steep embankments and hard-to-reach areas, keeping the operator out of the danger zone while the machine does the work.
(And yes — the videos of these machines crawling across banks are as satisfying as they look.)
3) A finish that matches Mount Nasura expectations
Mount Nasura isn’t “slash-and-dash” territory. People care about presentation, property value, and a tidy, maintained look — even on the difficult bits.
So we aim for a clean result: controlled cuts, neat edges where possible, and sensible ongoing maintenance plans that stop the hill from turning into a jungle again.
What we actually do (steep terrain services)
Steep slope mowing (banks, embankments, verges)
Overgrown slope knock-downs
Routine maintenance mowing on steep lawns
Verge mowing and tricky roadside edges
Bank clean-ups where brushcutting would take all day
Hillside garden and block clean-ups
Sometimes it’s not a “mow” — it’s a rescue mission.
Seasonal cut-backs
Removal of heavy overgrowth on banks
Clearing access paths (safely)
Green waste removal (where requested)
Add-on services that pair well with steep blocks
Steep properties often come with steep-roof homes, multi-storey layouts, and awkward access. So clients commonly bundle:
Gutter cleaning (especially hard-to-access homes)
Hedge trimming
Weed control (targeted and sensible, not scorched-earth)
General garden tidy-ups
The "Weed Wars": Arum Lily & Watsonia
If you’ve lived here for more than a winter, you know the enemy.
The Arum Lily. It looks pretty in a vase, but in our gullies, it’s a declared pest. It chokes out the native ferns and it’s toxic to dogs and horses.
Here is the mistake most people make: They try to slash it.
When you slash an Arum Lily, it laughs at you. The energy is stored in a massive tuber underground (like a potato). Slashing just tells the plant to grow back twice as fast. Plus, you risk spreading the seeds.
The ProHill Strategy: We offer a targeted chemical treatment program specifically for Arum Lily and Watsonia. We use a specific herbicide mix with a "penetrant" (a wetting agent) that sticks to those waxy leaves and travels down to kill the bulb.
Note: The best time to hit Arum Lilies is August to October, just before they flower. If you wait until summer, they die back naturally and hide underground, waiting to invade again next year.
Dealing with the African Black Beetle
Have you noticed dead, yellow patches in your lawn that seem to get bigger? Does the turf feel "spongy" when you walk on it? Can you pull the grass up like a piece of carpet?
That’s the African Black Beetle.
The larvae (curl grubs) sit underground and eat the roots of your expensive lawn. The birds (Magpies and Crows) know they are there, so they come in and tear up your turf to eat the grubs. It’s a double whammy.
This is a huge issue in the Perth Hills right now.
We can apply a professional-grade treatment (like Acelepryn) that targets the grubs without harming the birds or your pets. It gives you 6 months of protection. It’s an investment, but it’s cheaper than re-turfing your whole backyard.
You’ve seen the trailers. The big national franchises.
Now, some of those blokes are decent. But here’s the thing: many of them are bought by guys who have never held a whipper snipper before they signed the contract. They work off a script. They quote off a spreadsheet.
We are different.
I own the business. When you call, you speak to Jared. I’m the one responsible for the quality.
We support the community. We aren’t sending royalties to a head office in Melbourne. We’re buying our lunch at the Roley Stone Bakery and we’re putting money back into local clubs (Go the Tigers!).
We have the insurance. We carry $10 Million Public Liability. If a rock does fly (and in the Hills, it’s always a risk), you are covered. Don’t hire a cash-in-hand cowboy and risk your windows.
Why choose a "Local" over a Franchise?
A Simple, Ironclad Guarantee
I’ve read the Scott Pape books. I know you work hard for your money. I hate seeing people get ripped off by tradies who do a half-hearted job because they know you’re desperate.
So, here is the ProHill "Hills Local" Guarantee:
"We will turn up when we say we will. We will close the gate when we leave. If you aren't happy with the cut, the edging, or the cleanup, tell us within 24 hours and we will come back and fix it for free. If you still aren't happy, we will pay a competitor to fix it for you."
No weasel words. No fine print. Just a proper job.
Frequently Asked Questions
-
Yes, but we need to see it first. We have machines with low centres of gravity designed for gradients. If it’s a cliff face, we might need to brush cut it by hand. Send us a photo and we’ll tell you straight up if we can do it safely.
-
Absolutely. That’s our bread and butter. We call it a "Knockdown." It costs a bit more than a maintenance mow because it’s hard on the gear and takes three times as long, but we’ll get it back to a manageable level so you can maintain it.
-
We can. For residential lawns, we usually take the catchings. For large acreage slashing, we typically "side discharge" (mulch) the grass back into the paddock to feed the soil. If you need 5 acres of grass carted away, we can organise it, but the tip fees in Armadale are steep, so mulching is usually the smarter financial move.
-
Yes. In Roleystone, full gutters are a massive fire risk. We can blow them out while we are there for the lawn. Just ask for it in the quote.
-
We keep it simple. You don’t need to be home.
Text or Email us your address and a couple of photos of the jungle. We’ll look it up on satellite maps and give you an estimate.
If you’re happy, we book it in.

Ready to get your weekend back?
You could spend your Saturday fighting with a mower that won’t start, getting covered in dust, and worrying about snakes in the long grass.
Or you could take the family down to Roley Pools, have a pie at the bakery, and come home to a property that looks like a million bucks.
