AS 940 Sherpa 4WD RC is what happens when someone decides a ride-on mower should also be a remote-controlled rescue vehicle for grown-ups. On the flat, it’s a comfortable, fast, all-wheel-drive mulching mower. Point it at a slope that looks like it belongs on a warning sign, flick it into RC mode, and suddenly you’re standing at a safe distance while the Sherpa clings on and gets the job done.
This thing is built for operators who need one machine to handle everything: long grass, rough banks, awkward ditches, roadside verges and those “absolutely not walking on that” slopes. When the terrain is sensible, you sit and mow. When it’s not, you step off, grab the remote and let the Sherpa fight the hill while you stay clean, upright and uninjured. It’s simple, tough and strangely entertaining to use.
What the AS 940 Sherpa 4WD RC Is Built For
The Sherpa 4WD RC is designed for people who mow the sort of places everyone else pretends not to see. Long grass, soggy verges, sketchy slopes, awkward ditches — the jobs where you either need nerves of steel or a machine that saves you from doing something daft. This one does both. Ride it when the ground is friendly, switch to remote when the hill starts behaving like it wants to throw you into a hedge. It gives you speed on the flat and safety on the stupid bits, all in one machine.
Handling Real-World Slopes
The permanent four-wheel drive, limited-slip differential and low centre of gravity give the Sherpa a surprisingly stubborn determination to stay upright. Those new ATV tyres bite across slopes instead of sliding down them like a startled cow. And in remote mode, you can stay on the safe side of the slope while the Sherpa tiptoes around the dangerous side. It isn’t pretending to be a tracked flail, but for a wheeled machine it tackles banks most ride-ons wouldn’t dare look at.
Who This Machine Actually Suits
- Contractors who jump between big flat runs and “this is definitely a bad idea” slopes
- Councils managing verges, ditches and rough ground without sending staff into harm’s way
- Sports grounds and estates where the finish matters but the terrain doesn’t play nice
- Operators who want ride-on comfort, but also want to remain alive when the job gets risky
If someone needs extreme-slope, heavy brush clearance, they buy an Ovis or a Tahr. If they need one machine to cover everything from tidy grass to fairly evil slopes, they buy the Sherpa RC.
Real Strengths and Day-to-Day Advantages
The Ride-On That Knows When to Get Off
Most machines make you pick a side — either ride-on comfort or remote-control safety. The Sherpa RC lets you have both. When the ground is reasonable, you sit on a comfortable, well-suspended seat and crack on. When the bank starts looking like the beginning of an accident report, you step off and control it from a safe distance. No drama, no arguments, just a flick of a lever.
Cross-Blade Mulching That Actually Works
The cross-blade system doesn’t just cut; it shreds and drops the clippings between the wheels, which gives you grip on wet grass instead of rolling around on a layer of slime. It leaves a much cleaner finish than a flail, so public-facing sites don’t end up looking like they’ve been chewed by a tractor.
Built Around Operator Comfort
The seat adjusts for tall operators, the suspension takes the sting out of rough areas and the control layout is made for long days. It’s the sort of machine you can sit on for hours without needing a chiropractor, which is more than can be said for a lot of high-grass ride-ons.
Where It Sits in the AS Range
The Sherpa RC is the “one machine does it all” option. It’s not as slope-obsessed as the Ovis flails and not as specialised as the Tahr crawler, but it covers more types of terrain than anything else in the lineup. If you want ride-on speed, RC safety and a mulching finish in one package, this is the machine that ticks all three boxes.
Optional Accessories
Mulch Kit
For operators who want a finer finish on shorter grass. Handy on sports grounds and tidy public sites.
Snow Blade
Turns the Sherpa into a winter workhorse. Great for yards and pathways when the weather decides to be annoying.
Trailer & Hitch
Useful for site transport, moving tools or clearing debris between mowing runs.
Operational Realities
The Sherpa RC is easy to live with. The new fuel tank design gives you more runtime and easier filling, while the Plattfuss-Stop tyre sealant cuts down on puncture headaches. The frame is tough, the service points are accessible, and with the remote control acting as an on-board dashboard in ride-on mode, you’re never guessing what the machine is doing. It’s a straightforward, capable bit of kit that handles jobs most mowers sensibly avoid.
How Suffolk Mowers Supports Your Machine
Suffolk Mowers sets up every AS 940 Sherpa 4WD RC properly before it reaches your site. We check the deck, tyres, controls and safety systems so you’re not discovering problems on your first slope of the day. If you’re new to the RC side of things, we’ll walk you through how to switch modes, how the machine behaves on banks and what to watch for when you’re standing off to one side pressing buttons instead of sitting on it.
We keep the common wear parts in stock — belts, blades, filters and tyres — and we can supply the optional extras like the mulch kit or the snow blade without delay. Our workshop handles servicing, repairs and warranty work with short turnaround times, and if you’re running a mixed fleet, we’ll help you set servicing intervals that keep the Sherpa working instead of waiting on a bench. Practical help, sensible communication and no disappearing acts.
