Bosch Cordless Lawn Mower ROTAK18V2-38 (Without Battery And Charger)

What battery capacity is recommended for this mower?

Bosch recommends using 4.0Ah or 6.0Ah batteries for optimal performance. A 4.0Ah battery typically provides 30-40 minutes of cutting time depending on grass conditions and cutting height settings. For larger lawns, the 6.0Ah battery extends runtime to approximately 50-60 minutes. Two 4.0Ah batteries can handle up to 500 square metres of 18cm high grass according to user feedback.

How does the mulching function work?

The mulching function uses the included mulch plug to block the grass bag opening, causing clippings to be chopped repeatedly by the blade until they become fine particles. These particles fall back onto the lawn surface where they decompose naturally, providing nutrients to the grass. This eliminates the need for grass collection and reduces lawn maintenance whilst improving soil health.

What is the maximum lawn size this mower can handle?

The ROTAK18V2-38 is designed for medium to larger lawns, typically handling areas up to 600 square metres on a single battery charge. The actual coverage depends on grass height, density and terrain conditions. For very large lawns, having a spare battery ensures continuous operation without waiting for charging breaks.

How easy is it to adjust the cutting height?

The cutting height adjustment uses a single lever system that changes all four wheels simultaneously. The lever moves between seven preset positions from 30mm to 75mm in increments. The mechanism locks securely in each position and requires minimal effort to operate. This design ensures even cutting height across the entire lawn surface.

Does this mower work well on slopes?

The mower handles gentle slopes effectively due to its lightweight design and good wheel traction. However, Bosch recommends avoiding slopes steeper than 15 degrees for safety reasons. The mower's centre of gravity and wheel configuration provide stability on moderate inclines whilst maintaining cutting performance.

How do I maintain the brushless motor?

Brushless motors require minimal maintenance compared to traditional motors since they have no carbon brushes to replace. Regular cleaning of air vents and keeping the motor housing free from grass debris maintains optimal performance. The motor's electronic components are sealed against moisture, but storing the mower in a dry location extends its lifespan.

Can I use this mower in wet conditions?

Bosch advises against mowing wet grass as it can clog the cutting deck and grass bag whilst potentially damaging the lawn surface. Wet grass also increases power consumption, reducing battery runtime significantly. For best results, mow when grass is dry and conditions allow for clean cutting and efficient grass collection.

What accessories are available for this mower?

Available accessories include replacement grass bags, spare mulch plugs and various POWER FOR ALL battery capacities. Bosch also offers compatible chargers and battery storage solutions. The mower's design accommodates standard replacement blades when sharpening is no longer effective, ensuring long-term usability and performance maintenance.
