Nice mower about to pick a 54 up just like it. Had a 61 stander and then went 54 sit down and miss my stander. 61 is a little to wide though for small dips etc. I love the 54 width 👍
I also just purchased a BB 54 . The first thing i had to do was lvl out the deck as it was almost a inch off. So that would be the first thing you should do before you really get started weekly mowing. I could see where the nuts slipped up. After I adjusted them I used a impact to really crank that nut and hope it does not slip agian. I can see the front right hanger on your mower is down further then the rear worth the time to check it now 😀
