You probably won’t be satisfied with the mulching results, so after you take the mulch kit off you can measure from tip of blade to concrete with properly aired up tires to determine cutting height.I have Toro Timecutter 75755 50" cutting deck. I installed toro's recycle kit / mulching kit. The kit makes the underside of the deck completely enclothed. My question is how to measure the cutting height when you can't get to the inside of the deck where the blades are.
