Steve2018 3 #1 Posted February 20, 2019 Is it possible to replace the disc with 8 blades on to just a single blade? I think my blades are blunt as they seem to just flatten the grass but there's 8 at £15 each! Thanks Share this post Link to post Share on other sites
4x4forks 258 #2 Posted February 20, 2019 Cheep enough to have a go but balancing may be a issue . I think I would have a go Share this post Link to post Share on other sites

Wristpin 400 #4 Posted February 20, 2019 I would follow Nigel’s advice and sharpen the blades. The later 30” deck on the 604 had a bar blade but also a fan to create enough air flow to fill the bag. On your machine it is the wings on the 8 blades that create the air flow . Unless you are just going to cut and drop, I would keep them. Share this post Link to post Share on other sites

Eg a certain angle or as long as they sort of follow the original angle would that be ok? I remember sharpening a garden shredder blade that was blunt but still working sort of ok, i made it nice and sharp and it would shred anything...

Steve2018 3 #7 Posted February 21, 2019 Thanks had a look but all the bolts look untouched from the 80's and not wanting to budge. I got the main centre bolt out but the disc is stuck solid Might be easier removing the deck to attack them easier do you think? from the looks of it the deck is held on by just some R clips is this correct or am I missing something?

Stormin 4,458 #8 Posted February 22, 2019 I had a 504 and if I remember right, the deck is just held on by R clips. If you get it off, turn it upside down and soak the bolts in releasing fluid. Or apply some gentle heat. Share this post Link to post Share on other sites
