I HIT SOMETHING BIG WITH THE VENTRAC!!

What happens here

With the mower deck securely raised, perform a thorough visual inspection of all three blades. Check for dents, chips, bends, or excessive dullness, especially noting any damage from hitting rocks. The presenter identifies that the center blade on this model spins in the opposite direction to the outer two, and therefore the nuts on these blades will have a reverse thread. Using a DeWalt impact wrench with an appropriate socket, position it over the blade nut. Engage the impact wrench to quickly loosen and remove the nuts, then carefully detach the damaged blades. Remember the reverse threading on the middle blade to avoid stripping the bolt.

Goal: Visually inspect the mower blades for damage, then use an impact wrench to quickly remove any identified damaged blades, noting the reverse thread on certain blades.

Tools and materials

  • Appropriate socket
  • DeWalt impact wrench
  • Impact extension
  • Impact wrench adapter kit

What they say

Hide

underneath here so I've been in this situation before and I've raised the deck up on the ventrac and then start scratching my head as to which way the blades turn because they're sharp on both sides so on a pulley on the other side here I put an arrow to show which way they turn so these two blades actually turn this way and this other blade turns the opposite way so this blade closest to the right hand side turns the opposite way and you can see it turning very cool now the reason it works like this is because it basically pulls everything to the center of the machine and then the center blade basically pulverizes or chops it up and that's what I'm having a little bit of an issue with is the center blade I'm leaving a big pile of grass but it's not pulverizing it like I'd like it to so I'm checking to see if there's anything loose or dull or anything ridiculous that I see could be a problem the first thing I see is I creamed a rock with this blade right here and I've got to remove it real quick and sharpen it I have some blades on standby so I may end up just pulling the blade off and putting a new blade on because you know on rainy days I'll sharpen these blades I'll have everything ready to rock and roll and that way I can just do a quick removal and install and roll with it another thing we're going to do these are solid tires we're going to be unbolting the wheel assembly and we're gonna move it up probably yeah 2 inches or so something like that that way we don't scalp the grass quite as low as we're doing and we can roll with the mowing we can just get out there and go hopefully we can go three and a half to five miles an hour with this thing in optimum running condition but if you don't have it in optimum condition then this is what you run into it's not cutting good so when you hit rocks with lawn mower blades it breaks stuff what we'll be using is our big old Dewalt impact and we have the adapter kit so you can use the new style batteries with the old style tool so we'll rock and roll get this off now in case you don't know if one blade spins the opposite way that means that one of them are reverse-thread so the reverse thread is the one that spins the backwards way so we'll go in and remove the crappiest blade first and we'll inspect the rest of them we may hit it with a bench grinder real quick and we may get out the workshop and really sharpen them razor sharp so that I can move on with it it really makes a huge huge difference having ultra…
