A basic lawn visit is usually three machines, not a truck full of extras.
Mower
The mower cuts at a set height. Ask what height they use and whether they mulch or bag.
Spreader
A spreader puts down seed or fertilizer evenly. The product matters more than the brand of the cart.
Trimmer
The trimmer cleans the edges the mower misses. It should not scalp the grass along the walk.
