Is STIHL km90r a 4-stroke?

Yes, the STIHL KM90R is a 4-stroke engine. The 4-stroke engine operates differently than a 2-stroke engine, as a 4-stroke engine is engineered to require four distinct piston strokes (intake, compression, power, and exhaust) in order to complete a single cycle.

What is the difference between 2 stroke and 4-stroke grass cutter?

The main difference between a 2 stroke and 4-stroke grass cutter is the number of times that the piston completes its cycle in order for the machine to produce one power stroke. A 2 stroke grass cutter has a single piston stroke that powers the machine, while a 4-stroke grass cutter uses four separate strokes of the piston to power the machine.

In terms of performance, the 2 stroke grass cutter is able to deliver a lot of power in a short amount of time. This power delivers a lot of cutting speed, making it suitable for heavier jobs such as thick grass or weeds.

The 4 stroke grass cutter, on the other hand, delivers less power but is able to do so over a longer duration. This makes it better suited for lighter jobs such as trimming or edging, as they can maintain power while working but don’t have to work as quickly.

Another difference between the two engines is their emissions. Because of their higher power output, 2 stroke grass cutters produce more pollutants than their 4 stroke counterparts. This, along with their ability to make more noise, makes them less environmentally friendly, and is one of the main reasons why 4 stroke models are favored in many areas.

Both 2 and 4 stroke engines have their advantages and disadvantages, and it is up to the user to decide which one is best for their job.
