Grin HM46 IS Instart push lawnmower
46cm cutting width without collection with push-button electric start - ideal for those looking for maximum lightness without the stress of the starter cord.
This model is the definitive solution for those who want an agile yet technological machine : the maneuverability of the push model meets the power of the Instart engine, eliminating the effort of "pulling the rope" forever.
- ✔️ Grin system without collection: cuts, shreds and leaves the grass on the lawn as a natural fertilizer → zero stops and goodbye to grass clippings disposal
- ✔️ Instart (Button) Start: Just one click to go. Thanks to the lithium-ion battery integrated into the motor, starting is immediate and effortless.
- ✔️ Briggs & Stratton 675iS Series Engine: Powerful, reliable, and designed for repeated, worry-free starts → the pinnacle of American technology.
- ✔️ Unbeatable agility: The lack of traction makes the machine lighter and easier to maneuver around plants, flower beds and complex edges.
If you have a garden with many obstacles but are tired of the hassle of using a cord starter, the HM46 IS is the machine for you. It's incredibly light to push (because it doesn't have the weight of a full grass catcher) and starts as easily as a household appliance. It's a favorite among those who want to take care of their garden in complete relaxation.
👉 Compared to the standard HM46A model, it has identical cutting quality, but offers the convenience of electric start.
👉 Avoid it only if you have large, constant slopes, in which case it's better to evaluate the traction version (HM46A).
Is this the right lawnmower for you?
✔️ Yes if:
- 🔸Do you have a garden between 200 and 800 square meters ?
- 🔸You have many flowerbeds, trees or narrow passages where maximum agility is required
- 🔸You want an instant push-button start (ideal for those with arm/shoulder problems)
- 🔸Are you looking for a lightweight machine but with a professional Grin steel body?
❌ No if:
- 🔸Your garden is all on a steep slope (traction is better)
- 🔸You have flat and very long surfaces over 1000 m2 (where traction helps)
- 🔸Prefer the traditional rope starter to save on the initial price
Grin HM46 IS INSTART lawnmower: the revolution of electric push start.
The Grin HM46 IS Instart lawnmower is the ideal model for those looking for maximum lightness and maneuverability without sacrificing technological convenience: it is the only push lawnmower that starts with a simple button, eliminating the effort of the starter cord forever.
Thanks to the patented Grin system, this machine cuts, shreds, and fertilizes the lawn in a single pass : no bag, no stops, and no grass disposal. The combination of its agile 46 cm deck and electric start make it a favorite for those who want to maintain their garden without any physical effort.
Compared to the HM46A model , the HM46 IS is much lighter and more agile to maneuver manually. Choose it if your lawn is flat and full of flowerbeds; if, however, you have a steep slope, the HM46A's traction would help you.
Who is this lawnmower suitable for?
- Small or medium-sized gardens, 200-800m2, with many obstacles and flowerbeds
- For those seeking maximum lightness: the lack of traction makes the car extremely easy to drive
- Those who have difficulty with the pull-cord starter: perfect for those who want instant, effortless starting (elderly, women, or anyone who enjoys convenience)
- Those who want to completely eliminate grass collection by reducing working times by 50%
Why choose Grin HM46 IS INSTART PUSH?
Grin System: no collection, maximum time savings
The grass is pulverized inside the canopy and returned to the soil as nutrients. You'll no longer have to stop to empty the grass catcher or carry heavy bags to the landfill.
Instart start: just one button
Forget about tugging on the cord. The motor is equipped with a small lithium-ion battery that allows you to start the mower with a simple click, just like a modern car. A single charge lasts for the entire mowing season!
Briggs & Stratton 675iS Engine: American Reliability
The Instart engine is not only easy to start, it's also extremely powerful and reliable. Designed to last for years, it guarantees consistent performance even on thick lawns.
Push-button maneuverability: move with agility
Without the weight of a traction mechanism, the HM46 IS is a featherweight. You can maneuver around trees, bushes, and borders with a surgical precision that traction models simply can't match.
When is it NOT the right choice?
- If you have gardens with significant slopes (in which case the traction of the HM46A model is essential).
- If you want to collect the grass in the basket
- If you have flat and very large surfaces over 1000 m2 (where a traction model would reduce fatigue).
- If you are looking for an economical entry-level machine (here you pay for high technology and quality materials).
The Grin Instart system is the pinnacle of gardening technology: perfect for those who want a well-kept lawn with minimal space and maximum ease of use.
Grin HM46 IS INSTART vs HM46A: which one to choose?
| Characteristic | HM46 IS INSTART | HM46A |
|---|---|---|
| Advancement type | Ultra light push | Automatic traction |
| Engine start | Electric push button (Instart) | Manual rope |
| Maneuverability | Maximum (ideal between plants and flowerbeds) | Good |
| Slopes | Ideal for flat terrain | Perfect for climbs and bumps |
👉 Bottom line: Choose the Grin HM46 IS Instart lawnmower if you're looking for the absolute convenience of push-button start and have a flat garden with many obstacles that require agility. Choose the HM46A model instead if your lawn has slopes or if you prefer the machine to move forward automatically without any push from you.
If you are looking for a machine that does all the heavy lifting for you, you can also consider the Grin HM46A Instart self-propelled lawnmower .
✔ Same Instart push-button electric start
✔ Automatic traction so you don't have to push even a gram
✔ Ideal if your garden has slopes or if you prefer a constant pace without fatigue
👉 It's the right choice if you want the best Grin technology and don't want to give up either the button or the traction.
Nicolò 's usage tips and suggestions
If you've never tried Instart , prepare to change your mind about petrol lawnmowers: you'll feel the difference immediately, every time you start.
The real difference compared to the standard 46 cm?
The main advantage isn't just the cutting, but the stress it eliminates . No longer having to "fight" with the starter rope makes gardening a pleasure, not a gym workout.
The sensations in real use
- Absolute lightness: it feels like driving a toy, but it has the power of a professional machine.
- Mental silence: you stop to move an obstacle, turn off the engine and turn it back on in a second without thinking.
- Surgical maneuverability: it gets under hedges and around flowers with extreme ease.
When I really recommend it
- if you have a flat garden up to 800 m2
- if you have many plants or tight corners where traction would be a hindrance.
- if manual starting is tiring or annoying.
- if you want the most modern technology available on the market today.
An aspect that many underestimate
With an electric starter on a push-type machine, you optimize your work : you can turn off the engine every time you need to move a vase or a toy, knowing it will restart instantly with a click. You save fuel and work safely.
Pre-shipment inspection
As with all our machines, your Grin HM46 IS is unboxed, inspected, the battery tested , and the machine inspected before shipping. You receive it ready to use.
My final advice
If you have a city or medium-sized garden and are looking for a technological, very light machine without the weight of the bag , the Grin HM46 IS Instart is the best gift you can give yourself to truly enjoy your lawn.

Questions & Answers about the Grin HM 46 IS Instart lawnmower - 46cm - Push
How long does the starter battery last?
The Briggs & Stratton lithium-ion battery is designed to last a very long time. A full charge provides over 50 starts , which is plenty for several mowing sessions. It also fully charges in an hour, but if you're in a hurry, a quick charge of just 10 minutes will provide 10-15 starts.
What happens if the battery runs out while I'm working?
It's almost impossible to run out of power if you charge it at the start of the season, but the battery is removable and as small as a power drill. You can take it to the garage, charge it for a few minutes, and get right back to finishing the lawn. There's no cord, so the button is your only (and very reliable) start-up method.
Isn't the push model tiring for 800m2?
On the contrary! Grin's strength lies in the absence of a grass catcher. With a traditional lawnmower, after 15 minutes you push 20 kg of grass into the basket. With the HM46 IS , you only push the weight of the machine (which is among the lightest in its category). On a flat lawn, the smoothness of the Grin bearings makes pushing almost effortless.
Is the Instart system sensitive to humidity or cold?
No, Instart technology is tested for extreme conditions. The contacts are protected and the lithium battery does not suffer from the memory effect. It is much more reliable than older key-operated electric starters with lead-acid batteries: the technology here is the same as that used in professional power tools.
Can I leave the battery in during the winter?
Expert advice is to remove the battery during winter storage and store it in a dry place at a mild temperature. This preserves the chemistry of the lithium cells, ensuring that your Grin will start right away the following spring without having to buy anything new.
If the engine is off, is the car easy to move?
Yes, since it's a push model, it doesn't have the resistance of traction gears. It's free and very light in movement, ideal if you need to move it with the engine off in garages or narrow driveways.

Recensione acquisto
Il prodotto è stato provato e soddisfa le nostre aspettative, per quanto riguarda la spedizione l'unico neo il corriere purtroppo devo segnalare che BRT con la filiale di Monza Concorezzo non è all'altezza di fare questi lavori, già altre volte mi sono trovato in difficoltà nel ricevere i pacchi da questa filiale.
