Re: Can I run an older deck on a newer mower
I called the dealership and asked the service department if the old deck could go on the newer mower. I was told it wouldn't. This is also the same guy that told me I'd need 4 self tapping screws to mount a spindle assembly in my deck when I was just able to use the old nuts from the one I replaced, so take that for what it's worth.
I first changed the blades to new ones and greased up the spindles. No change. Pulled the deck again to take the belt off to see how the spindles were doing. One was rough to turn and made a growl. Got it off and replaced the whole assembly with a new one. Greased it up, put the deck back on, engaged the blades... same vibration, although maybe just a tad better, and oddly enough, the new assembly turned just as rough and made the same sound as the old one I thought was bad. Pulled and mounted the deck again to try two new idler pulleys for giggles. Possibly a bit improved, but maybe I'm just getting used to it. It's still there for sure.
I've pulled and mounted this deck three times now in a week. I'm getting tired of it, although I'm getting faster at the whole deal with practice. Still, I don't want to pull and mount two decks if I find out I can't swap them... I don't have tons of free time.
Both belts are good, or at least seem as though they are. The previous owner replaced them last summer, but not sure how much use they have on them in that time. Strangely enough though, now that it's been mentioned, I just noticed black marks on the deck that I'm pretty sure must be coming from the blade belt as it travels around the middle spindle, and coincidentally, that's the spindle I thought was bad and replaced. I wonder if there is something wrong with the shell of the deck itself that would have made the new assembly sound and turn bad like the other one? It's worth investigating at least. I'll have my wife sit on it and engage the blades so I can take a look as best I can at what's going on with the belt. I sort of feel dumb I didn't do that first.
The vibration is definitely not there until the blades are engaged. I didn't know it would be safe to power up the deck belt without the blades mounted. I'll try that as part of the troubleshooting.
As far as the suggestion made above to "Release the tension on the deck drive belt to see if it is in the PTO while it is running." I'm not sure what that means exactly. Should I literally take the drive belt off and then pull up the knob that engages the blades?
