This tool resembles a lawn mower and has several vertically mounted blades set to penetrate the soil slightly for dethatching and scarifying.

• A. Vertical Mower
• B. Power Seeder
• C. Dethatcher
• D. Block Plane

Answer: (A)

Vertical mowing uses blades mounted vertically that slice into the turf to remove thatch and lightly scarify the surface. This action concentrates cutting depth along vertical planes, which helps sever thatch mats and create small channels in the soil for better air, water, and root penetration. The equipment often looks like a lawn mower with a deck and wheels, but its blades are oriented to cut vertically rather than glide across the top.

This is why the tool described fits best: its purpose is dethatching and scarifying through vertical cutting, not seeding or surface raking. The other options don’t match the described function: a dethatcher mostly uses horizontal tines to lift thatch, a power seeder spreads seed, and a block plane is a woodworking tool rather than lawn equipment.
