Güde RM 36-402-30.37 cordless lawn mower – 370 mm, 72 minutes runtime
The RM 36-402-30.37 has been designed for medium to large gardens where continuous runtime is a priority. Compared to the single-battery models in the Güde range, the 36V dual-battery system (2 × 18V) provides 72 minutes of uninterrupted runtime, enough to mow up to 500–600 m² on a single charge without changing the battery. The 370 mm cutting width significantly reduces working time compared to smaller models (280–330 mm).
The brushless motor operates at 2,900 rpm and is energy-efficient when powered by battery. Unlike petrol models, it does not produce excessive vibrations and requires minimal maintenance. Both batteries are installed at the same time and alternate automatically during operation.
Key features:
-
2,900 rpm brushless motor – Higher energy efficiency and reduced wear with lithium battery power
-
Modular battery system – 2 × 18V 4.0 Ah batteries are interchangeable with other batteries from the Güde 18V range (from 2.0 to 4.0 Ah)
-
72-minute runtime – Covers 500–600 m² gardens without intermediate charging
-
35-litre grass catcher – Reduces interruptions for emptying on larger gardens
-
Dual charger – Charges 2 batteries simultaneously in 96 minutes, ideal for two mowing sessions
-
Asymmetric wheels – 152 mm front wheels and 203 mm rear wheels for manoeuvrability on mixed terrain
-
Foldable handle – Makes transport and storage in a garage or utility room easier
Who the RM 36-402-30.37 is suitable for
| Profile |
Suitable? |
Reason |
| Hobby user with a 400–700 m² garden |
Ideal |
72-minute runtime covers medium to large gardens on one charge; 370 mm width is efficient; 35L grass catcher reduces frequent emptying |
| Small landscaper / green maintenance operator (2–4 properties/week) |
Suitable |
Reliable brushless motor; interchangeable batteries allow work continuity; dual charger is ideal for multiple shifts |
| Professional mowing contractor / intensive gardening use (100+ properties/year) |
Not recommended |
72-minute runtime and 35L grass catcher are insufficient for continuous 8+ hour shifts; 230V three-phase models or petrol engines with 4+ hours runtime are required |
Not suitable for: gardens under 300 m² (oversized tool), gardens over 1,000 m² without additional batteries, areas with very tall or dense grass (pre-mowing required), daily industrial-level use, very damp or wet environments.

Frequently asked questions
How many minutes of runtime do I really get with the RM 36-402-30.37?
With both 4.0 Ah batteries fully charged, you get 72 minutes of continuous operation at maximum speed on medium-length grass. On low or very short grass, runtime may increase slightly; on thick, wet or very dense grass, it may be reduced by 10–20%. The two batteries alternate automatically without interrupting operation.
Can I buy just one additional battery to double the runtime?
Yes. By purchasing an additional AP 18-40 battery (4.0 Ah), you will have 4 batteries in total (2 pairs). With the supplied dual charger, charging 2 batteries takes 96 minutes. Two mowing sessions (72 min + 72 min) = 144 minutes total, with a 96-minute charging break between sessions. This is practical for 900–1,200 m² gardens.
Can the RM 36-402-30.37 cut wet grass?
Technically yes, but it is not recommended. Wet grass increases the load on the brushless motor, reducing runtime by up to 20%, and may cause clogging in the grass catcher. Wait 2–3 hours after rain for optimal performance.
What is the difference between the RM 36-402-30.37 and a Güde single-battery model?
The 36V dual-battery system provides 72 minutes of uninterrupted work. Güde single-battery models (RM 18-) offer a runtime of 30–45 minutes. If your garden is larger than 400 m², the RM 36-402-30.37 is more efficient because you avoid changing batteries while mowing.
Are the batteries compatible with other Güde 18V tools?
Yes, the 18V AP Li-Ion batteries (2.0, 3.0, 4.0 Ah) are interchangeable with any Güde 18V tool from the same series (drills, chainsaws, branch cutters, pumps, etc.). They are also compatible with LG 18-30 fast chargers if purchased separately.
How much does the RM 36-402-30.37 weigh with both batteries?
The machine’s net weight is 14.2 kg. With 2 × 4.0 Ah batteries (approx. 0.4 kg each), the total operating weight is around 15 kg. It is easy to push even during extended sessions thanks to the height-adjustable handle and well-sized wheels.
Does the RM 36-402-30.37 support mulching?
Yes, it is included in the kit (mulching wedges supplied). The clippings are finely shredded and redistributed onto the lawn, enriching the soil with natural nitrogen. Use this function on lawns that are already in good condition; on deteriorated lawns, use traditional collection first for 2–3 months.
What maintenance does the RM 36-402-30.37 require?
Minimal maintenance. After each use: empty the grass catcher and clean the cutting deck with low-pressure compressed air. Every 20 operating hours: inspect the blades (sharpen if necessary with a 120–150 grit manual grinder). Every 40 hours: check the wheel bearings. Batteries should be stored charged in a dry place at 5–25°C; do not leave them fully discharged for long periods.
