It Fits My CRT306 After All

I made a mistake in assembly. I tried to edit my previous review that says "It doesn't fit my CRT306" to correct my bad review. I couldn't seem to change it to admit I was wrong. So I wrote another review. The grass catcher fits perfectly. I made my mistake in Step 2. I bolted the "iron pipe" on the outside of the chrome brackets instead of the inside. My apologies to Greenworks for my previous review.

I made an excellent choice

(This review was collected as part of a promotion.) I am impressed with the outstanding performance of the lawnmower. The power remains consistent throughout the cutting of the grass. The ease of setup was simple, following the easy to understand, instructions. I also like the handle folds in for stand on end storage.

80V 42" Cordless Battery CrossoverT Riding Lawn Mo

Works great so far. Able to mow about 1,5 acres before battery slows down. my only "complaint" so far is the reverse with blades on as one needs to stop mowing, turn off the blades, push the button and keep holding it as you turn the blades back on.
