Graham Spray Equipment, a manufacturer of spray rigs and equipment, released three new tools for lawn and tree care professionals: the GSE Deep Root Fertilizer Gun, the GSE Tiger Tiller and the GSE Trident.

The GSE Deep Root Fertilizer Gun is designed for surface spraying or root feeding trees and shrubs to a depth of 6 inches. A spring-loaded splash guard prevents liquid fertilizer from spraying back up as it’s injected into the ground, the company said. The GSE gun is compatible with pressure systems up to 600 psi and can deliver up to 4 gallons of fertilizer per minute.

The GSE Tiger Tiller is designed to rough up the ground for reseeding bare spots in established lawns and seeding new areas. It features all-steel construction, three 12-pronged rotating heads and a foam handle.

The GSE Trident is a coring-type aerator designed for tight spots that cannot accommodate a full-sized aerator. Three steel prongs penetrate dense, compacted soil, removing 3- to 4-inch plugs to let air, water and nutrients travel to the root system of turf, according to Graham. Like the Tiger Tiller, it features all-steel construction and a foam handle.

All three products come with a lifetime warranty.
