The Exmark Lazer Z D-series is the diesel-powered Exmark series. An over-the engine radiator with maximized airflow keeps the engine temperature low for longer engine life. The LZD diesel is built with a 60" or 72" UltraCut Series 5 mower deck. A canister style air filtration system supplies air to the engine. Some mower decks feature rear grass discharge for mowing in places where discharge has to be controlled well. Six cone-shaped anti-scalp rollers are mounted to the deck. The front caster tires, size 13 x 6.5-6 are smooth treaded semi-pneumatic tires. The drive tires are MultiTrac 26 x 12-12 4-ply tires. A 250 ft-lb. MagStop electromagnetic clutch with a spot brake feature engages the PTO mower deck. The parking brake system is a lever controlled drum and band configuration that works together with a transmission neutral interlock. The operator seat is a bolstered full-suspension seat with armrests that can be adjusted up and down.
