The DCMW220 runs two 20V batteries in series for 40V total output. It’s a commercial-oriented mower — steel deck, heavier bag frame, serviceable drive assembly — and it feels like one. Expensive but genuinely tough.
The self-propel clutch (a wet pack clutch) wears at about year five on a daily-use schedule. The deck-height adjuster lever’s return spring loses tension. Blade-shaft seals weep grease after about 500 hours.
Sharpen blade every 10 cuts. Inspect the clutch pack every 100 hours. Change the blade-shaft lube annually (DeWalt spec, not a lifetime part despite what owners think).
