Exmark Commercial 21 X-Series

The Exmark Commercial 21 X-Series was built for the operator who wants professional results without wrestling a big mower through tight gates, around landscaping, and into spots a zero-turn can't reach. At 21 inches wide with a die-cast aluminum deck, it's a precision tool for the areas that matter most.

The Kawasaki FJ180V KAI engine is a commercial-grade powerplant chosen for durability, not cost savings. Running at 3,300 RPM with a dual element air filter, it handles the stop-and-go of detailed mowing without overheating or flooding. The belt-drive system and Blade Brake Clutch (BBC) give you instant blade engagement and disengagement — useful when you need to move around obstacles without shutting everything down.

The 5"-deep, 1/4"-thick die-cast aluminum deck is built thicker than stamped steel decks and won't dent or crack the way stamped decks sometimes do on rough terrain. Cutting height adjusts from 1.0" to 4.5" in 0.5" increments, giving you nine distinct positions to dial in exactly the height your turf needs — not just high, medium, or low.

The 2.5-bushel (20-gallon) rear bag handles significant volume before you need to stop and empty it. The easy on/off bag design eliminates levers and latches and uses a top-fill window so you can see at a glance how full you are. Prefer mulching? The mulch plug comes standard. Switch between bagging and mulching without buying anything extra.

The infinitely variable transmission from General Transmissions doesn't lock you into fixed gear speeds. You set the pace — whether you're moving carefully around flower beds at a slow walk or covering straight-run areas at the full 4.2 MPH. There's no searching for the right gear. Your hands control the speed, and the mower follows.
