Firebug 267 #1 Posted April 30, 2020 I have a toro deck # 78345 on my 310-8. Mowed last weekend and it looked pretty bad. I know I need to do some height adjusting and such. I noticed that there is probably a 1/2-1 inch gap between the blades. Thought I’d order new blades but there are so many different part number that pop up when I try to look up 42 inch dd blades. Can anyone shed any light on what is correct for that deck? Why so many different part numbers ? And is there a difference between the sd and rd blades Share this post Link to post Share on other sites
lynnmor 7,302 #2 Posted April 30, 2020 (edited) I believe this is the correct blades. I also think there is a difference between SD & RD. Toro site. Get the manual in the manuals section. The blades don't need to be real close since they are staggered and overlap the cutting path. Did you adjust the transport height? Did you level the deck?

WVHillbilly520H 10,373 #3 Posted May 1, 2020 If your deck is the model 78345 42" SD then this is the correct blade kit 14" Toro # 106636 Share this post Link to post Share on other sites
