Anyone who maintains slopes in Styria, the Salzkammergut, or any other alpine region has known the motor mower for decades. Single-axle mowers with double-blade bars, brands like Brielmaier, Reform, Aebi, or Rapid – devices that have accompanied generations of farmers, alpine farmers, and construction yards. They have worked. They still work.
But: They are no longer up to date in many areas of application.
In recent years, a new class of machines has emerged that is increasingly replacing the classic slope mower – the remote-controlled mowing caterpillar. In this article, we show why the switch makes sense in terms of safety, health, and economics – and where the motor mower still has its justification.

The motor mower on steep slopes: An honest assessment
A motor mower is essentially a single-axle machine with a mowing bar that the operator pulls behind them. Strong, durable, relatively inexpensive to purchase – these are the arguments that have kept it on the market for decades.
But anyone who has spent a morning with a 15-horsepower single-axle mower on a 70% slope knows the other side:
- Physical maximum load.Holding the handle, guiding the machine over the slope, working against its own weight, while also paying attention to one's own stance. After three hours, the operator is physically at their limit.
- Vibrations and noise.Working for hours on the slopes demonstrably leads to strain on the spine, shoulders, and hands. Hand-arm vibration is an acknowledged occupational risk.
- Safety risk.The operator stands directly on the slope. On wet ground, loose soil, or with a sudden obstacle, the risk of falling is real – with potentially serious consequences if the mower comes along.
- Weather dependency.In wet conditions or with excessive vegetation, the use is often no longer justifiable. This means: rescheduling appointments, vegetation continues to grow, and effort increases with each day.
- Limited slope.Even specialized slope mowers reach their limits in practice at 70–80%. Over 80% slope and on wet ground, it becomes critical – both for the machine and for the person.
This is not a criticism of a generation of machines that have done their job. It is an assessment – and the basis for seriously considering a mower alternative.
What is a mower crawler – and what makes it different?
A mower crawler is a remote-controlled crawler mower with a tracked drive. Instead of operating the machine themselves, the operator controls it from a safe distance using a radio remote control. With modern devices like theJack MulcherorJack Schlegelthe radio range is up to 200 meters, the maximum slope is 100% (45°), and the area performance is up to 4,000 m² per hour.
The difference in practice is fundamental:
- The operator stands at the edge of the path, at the top of the slope crown, or in any other safe position – never in the danger zone.
- The machine operates at full power, even in places where no person would stand.
- The chain drive with steel insert provides traction even in wet conditions, soft ground, or loose soil.
- In case of a connection failure, the machine automatically shuts down. An emergency stop switch on the transmitter is always available. A chain guard curtain prevents stones or material from being thrown out.
In short: What a person does with a motor mower – balance, effort, risk assessment – is taken over by the machine in the crawler mower. The operator transitions from physical labor to technician.
Direktvergleich: Motormäher (Brielmaier, Aebi, Reform) vs. Mähraupe
| Criterion | Motor mower (single-axle) | Crawler mower (e.g., Jack) |
|---|---|---|
| Maximum incline | approx. 60–80 % | up to 100 % (45°) |
| Position of the operator | directly on the slope | up to 200 m away |
| Physical strain | high | very low |
| Weather dependence | high (wetness critical) | low (chain drive) |
| Area performance | approx. 1,000–2,000 m²/h | up to 4,000 m²/h |
| Noise and vibration exposure | high | minimal |
| Safety risk | significant | very low |
| Training effort | high (slope experience required) | manageable |
| Acquisition costs | lower | higher |
| Total costs over 5 years | medium to high (person hours!) | medium |
The table shows: In terms of pure purchase price, the motor mower is ahead. However, once the ongoing costs – especially personnel hours, downtime, insurance premiums, and health-related follow-up costs – are taken into account, the picture changes significantly. This is where the economicadvantages of the tracked mower, which are often underestimated in the purchase discussion.
Top 5 Gründe für den Umstieg von Brielmaier, Aebi oder Reform auf die Mähraupe
1. Safety that is non-negotiable
A motor mower can tip over on a steep slope. The operator can slip. Both happen in practice – the AUVA documents hillside mower accidents in agriculture and forestry every year. With a tracked mower, this risk is practically eliminated, as the operator no longer stays in the danger zone. For municipalities, construction yards, energy suppliers, and their insurers, this point alone is often decisive.
2. Slopes up to 100% – even in wet conditions
Where a classicmotor mower reaches its limits on steep slopesbetween 60 and 80% incline, a tracked mower like the Jack with chain drive and steel insert works reliably up to 100%. Wet embankments, loose soil, and uneven terrain are no longer a problem. This finally makes maintenance appointments predictable – instead of being dependent on the weather. Anyone planning a mountain project in June can rely on it taking place in June.
3. Up to 60% time savings per use
With an area performance of up to 4,000 m² per hour, a mowing crawler mows significantly more area than a motor mower – and a single operator often replaces a team of two to three people. On a road embankment or a mountain slope, the operating time can be reduced by 50–60%. With recurring maintenance intervals, the switch quickly pays off.
4. No more physical strain
Mowing on slopes with a single-axle mower is heavy work – vibrations, heat, noise, and constant concentration on one's own position take their toll, especially on older operators. Anyone who has controlled a mowing crawler via remote control describes the difference almost always the same: the work is not only safer but also physically more relaxed. For businesses with recruitment problems or an aging workforce, this is a key argument.
5. Versatility that the motor mower does not offer
A modern mowing crawler is not just a slope mower. With a height of 76 cm, the Jack Mulcher can operate under elevated photovoltaic modules, under guardrails, or in narrow vineyard rows. The Jack Flail with Y-blades handles woody growth, bracken, and blackberries – tasks that every classic sickle mower fails at. A mowing crawler thus covers areas of application that previously required several specialized devices.
Wann sind Brielmaier, Aebi oder Reform trotzdem noch die richtige Wahl?
We want to be honest: there are scenarios in which a motor mower is still sensible.
- Small areas under 500 m²,that only need to be mowed a few times a year.
- Very tight, winding areas,where even a compact mowing crawler (width from 131 cm) does not fit.
- Very rare use,where a mowing service does not make sense.
- Existing machine,which will run for many more years and is sufficient for occasional maintenance.
For everything else – regular slope maintenance, alpine farming, solar park maintenance, vineyard row mowing, municipal green spaces, industrial and landfill sites – the mowing caterpillar is simply the superior tool today.
Hangmäher kaufen oder Mähservice nutzen? — Was kostet ein Motormäher im Vergleich?
Anyone who wants tobuy a slope mowerfaces the next decision: own purchase or service?
Reasons for own purchase include:
- Regular own need (multiple uses per month)
- Own trained personnel available
- Possibility to rent the machine or offer services
Reasons for the mowing service include:
- Only seasonal or occasional need
- No own trained personnel
- Desire for predictable costs without investment
- Insurance and maintenance issues should be outsourced
Jack Works offers both options: the sale of the machines Jack Mulcher and Jack Schlegel as well as a complete mowing service with operator, transport, fuel, and machine maintenance. Which option fits better can be clarified in a short conversation – often a needs analysis based on photos or videos of the area is already helpful.
Praxisbeispiel: Almpflege in der Obersteiermark — vom Brielmaier-Einsatz zur Jack-Mähraupe
A pasture area in the western Styrian mountains with a slope of 50–100%, heavily overgrown with bracken over several years. Traditionally, this would have meant: two to three people with brush cutters, several days of work, high risk of accidents on the steep slope. With a motor mower, the slope would simply have been unmanageable in many areas.
The machine was transported to the pasture by trailer and operated remotely from the pasture path using radio. Area performance: about 4,000 m²/h. Result: The entire pasture was mechanically maintained in one working day – without anyone having to enter the slope. The requirements for the AMA area funding were met again, and the cultural landscape was preserved.
The mowing caterpillar was developed specifically for such tasks – not as a toy, but as a pragmatic response to real problems in local agriculture and pasture management.
Häufige Fragen zum Motormäher-Wechsel auf die Mähraupe
Conclusion: The motor mower has made history – the mowing caterpillar continues to write it.
The motor mower is not "bad". It has supported generations of slope operations. But the demands have changed: personnel is becoming scarcer, safety standards stricter, areas larger, maintenance cycles tighter, and insurers more critical. In this reality, the remote-controlled mowing caterpillar is no longer the exoticmotor mower alternative– it is the contemporary answer.
Anyone considering a new machine today should not see the mowing caterpillar as an expensive toy, but as a tool that removes people from danger zones, makes maintenance costs calculable, and opens up areas that can no longer be economically managed with traditional technology.
