A friend gave me a leaf blower a few years ago. Since then I always blow the clippings off the deck when I'm through. Takes about two minutes. Before that I used a shop vac. Took a lot longer.Occasionally, I have to clean and lube the deck channel and idler mount (where the idler pulley mount slides, the part on the deck that moves when the engagement lever is moved upwards to move the cable).View attachment 58349
That was in '09, and I dint know any better. ¯\_(ツ)_/¯Oh.... warranty should have took care of that.
I'm with Mparr here. I had a similar issue about 8 years ago where it was getting gradually more difficult to engage the deck to the point that I cracked the mower clutch. Also make sure you have the right clutch cable for your mower, not a cheap substitute. Maybe you can keep deck on the ground and hook up clutch & cable and have someone engage the clutch while you are watching below to determine what is resisting. From the low grain picture it does look like it need a good lube at the minimum. Debris build up of grass & dirt can do wonders creating friction for parts that should be moving freely.Again, for guidance only. Your part numbers may be different.
iF THE CABLE MOVES FREELY, the problem is most likely the deck and most likely the brake system. Many times we find the cheap brake systems are the problem and it can be hard to detect.The only names I know for most of the parts are the ones I see in the parts manual that came with it. When one of you says X and I ask if that's Y, it's just me trying to learn something; last thing I'd be likely to do on here is correct one of you guys.
