How is the hydrostatic drive different from a fixed-speed mower?

You set the ground speed steplessly within the 2.6 to 4.6 km/h range instead of picking a gear. That lets you slow down near obstacles and speed up on open lawn.

Yes. It has a mulching function, so you can return clippings to the lawn instead of bagging them. A multi-blade cutting system works with the deck airflow.

How big a lawn is it meant for?

Stihl rates it for lawns up to about 2,500 m². The 53 cm width and 70-liter catcher keep refill stops down on larger yards.

What engine does it use?

A Kohler HD775 OHV engine with 173 cm³ displacement. It is a gasoline engine, so it needs fuel and regular oil checks.

What comes in the box?

The mower itself. The grass catcher box is part of the machine, and the handlebar folds for storage.

How heavy is it to move around?

It weighs 54 kg. The drive helps while mowing, but lifting it into a truck or up steps is a two-person job.

Our take on the Stihl RM 655 YS Hydro Premium Gas Powered Push Lawn Mower

The Stihl RM 655 YS Hydro Premium is a self-propelled gas walk-behind mower with a 21-inch aluminum deck and a 173 cc Kohler HD775 OHV engine. Its hydrostatic drive lets you set ground speed steplessly between roughly 1.6 and 2.9 mph, which is the main step up from Stihl's fixed-speed RM models. The 70-liter catcher with a fill-level indicator and the fold-open design cut down on emptying stops, and the deck adjusts from 25 to 85 mm. It suits larger residential lawns where you want variable pace and mulching flexibility; the trade-off is a heavy 54 kg machine and a premium build that costs more than typical push mowers.
