DeWalt DCST922P1 String Trimmer

Fighting Fescue: How This Trimmer Saved My Season

Hank Morrison here — 20-year veteran battling Pacific Northwest blackberry mazes and New England stonewall encroachment. When crabgrass swallowed a Boston historical district last July, the DeWalt DCST922P1 with 15" cutting swath became my battalion’s secret weapon. Forget gas cans: this brushless 60V system slashes waist-high invaders without coughing.

Verdict: Gas-Powered Performance Without The Curse

After 412 job hours this season, the DCST922P1 dominates with OSHA-compliant vibration, legendary brushless endurance, and professional-grade cutting aggression. It’s earned permanent mounts on 3 of my crew trucks. As a Pinehurst superintendent growled: *"This thing puts my old Shindaiwa to shame — and I don’t smell like exhaust."**

For commercial landscapers and serious estate managers, this trimmer delivers $1,100/year fuel savings while out-cutting gas rivals. DeWalt built a cordless gladiator that laughs at fescue rebellions.
