Old GTS5 blade won't engage.

[kbowley]

Has been the most reliable mower ever.Always starts 1st pull and always engages blade when lever is pulled back.Worked fine
on last use before winterizing.Started yesterday on 1st pull after being stored since Nov. All seemed normal but blade would not engage.
I did notice that while warming up the motor kinda bogged down a bit when trying to engage the blade.seems like something has decided
to bind up while in storage.Need your experience please. Charlie

Charlie, flip the mower onto its right side and check the clutch visibly, and check for any side slop by grabbing the blade as well as disconnecting the spark plug and rotating the blade. Does it turn by hand? Next, use a bungy cord to hold the blade engagement arm in the engaged position and rotate the blade...the engine should turn with the blade

is the brake releasing properly....?

Thanks guys.Thanks Toby for the step by step instructions.Thats exactly what I need....step by step.I
will pressure wash the underdeck and soak any bolts before any wrenching.Charlie

Good top Kbowley!!! Thanks.I know for sure that the blade does turn by hand with some friction noise when not engaged.

You can call it a clutch, but if you look closely you will see that it nothing more than a CV drive where the more tension you put on the handle, the faster the unit will drive and the blade will engage with very little tension on the handle. Take a look at the manual I posted earlier to see how this works. If it seems to be going slower, the most common cause would be a worn belt or bad idler pulley.

Looks like my under deck cover is metal.Couldnt find my PB blaster so I used Seafoam.I will spray it a few times and try to loosen in a few days.Looks relatively clean though.Guess I should have my map torch on hand just in case.Charlie

The blade turned relatively freely both ways.No engine movement with engagement arm pulled to handle.Charlie

Either the clutch is worn, or the cable needs to be adjusted to further engage the clutch. I would try to snug up (shorten) the cable via the adjustment on the cable first. Let me know, okay? You may need some Liquid Wrench to soak the threads/nut on the cable adjustment nut.

Can you turn the blade by hand with the engine off? Just in case the bearings are froze. If they turn, then the belt is worn and too loose or the linkage is out of adjustment. Cable housing clamp may be loose and slipped, or maybe the engagement cable broke.

Yes it turns by hand whether engaged at the handle or not.I did not try to turn it while running.I will be getting a look under the metal(not plastic) undercover this week.Still soaking the bolts but they DO look pretty clean.Charlie
