Thank you. The improvements are appreciated. Especially, the wheels and the springs for the J-hook.

Not sure what is so difficult with assembly. Followed this video and I thought it was a breeze. Awesome pruduct!!!

Got mine today and WOW, and I agree with @zaineridling , the handle bar cable system for the safety latch was a mess to install and just unnecessary (I didn't see it as part of the unit when I bought it). I found this video and even the Manufacturer states in the comments they include the "pin and click pin so that you can use it the old way" Basically the simple way lol. Otherwise it appears strong enough to do the job.

Does this jack lift the mower high enough to get an impact wrench under the deck for blade removal?

How much $

Too complex. Go back to the classic, simple version which is easy and works as direct as a hammer. The handle-cable part is superfluous and makes the device unnecessarily complex.
