Neither. It is a physical activity. See the link below for an explanation of physical and chemical properties.
Cutting grass is a physical property, as it involves physically altering the shape or size of the grass. It does not involve a chemical change or alter the composition of the grass.
It is a physical change because it is still grass. Nothing new has been made.
Mowing is a mechanical process, not a chemical reaction.
grass growing is a physical change.
It is a biochemical process.
Hence,the formation of dew and frost is a physical change.
This is a phenomenon of physics.
Cutting doesn't change the chemical composition.
Lawn-mowing is a physical change, whereas the grass dying is chemical.
It is a physical change because paper is still paper and its the same even if it has been cut. If the paper were say to get burned it would be chemical change because it is no longer paper and it has a different form.
It is a physical change because it is still grass. Nothing new has been made.

It is a biochemical process.
A neighbor cannot place a lien on your property for cutting the grass unless he has a written agreement with you stating that you will pay him to cut the grass. There would then need to be a breach of that agreement and the neighbor would need to obtain a court judgment in his favor. However, in most jurisdictions, a town can order the clean up of a derelict property and record a lien for their costs.
Hence,the formation of dew and frost is a physical change.
Frost is a physical change, the condensation and freezing of water vapor.
