Hello, I'm curious if it would be safe to use a 1/4" blade spacer above the blade on a lazer z hp to get a little more effective deck depth. Seems like if torqued down properly it would be ok. Also, would it cause blowout problems? My unit is in the shop and I can't check the blade clearance vs. the edge of the deck. My fixed deck mower uses these spacers and adding more spacers above the blade and below the spindle improved the performance noticeably. My goal is better performance on taller grass.
