I started cutting the last part of the yard on Monday afternoon around 14h00. Everything started out fine. I was in the north forty, but then it all went south. The self-propelled feature of the lawnmower quit. I had to stop because, with my back, I can't muscle a lawnmower around the yard without a little help. The first thing I tried was to turn the adjustment screws on the cable that activates the drive wheels. No change.
The back yard, all mowed, Tuesday morning at about 08h30. Ken's done a really good job tilling up the vegetable garden plot.
I turned the mower over on its side, reached underneath, and found the lever that the cable activates. It moved back and forth just fine. I righted the mower and started it again. No change. I turned it over again and turned one of the drive wheels. It turned normally. I tried the other one. All ok. I took the hub caps off and checked the gears that turn the wheels. All seemed normal. Righted the mower, started it up again. No change.
Now I was starting to swear. The mower is pretty new. I went into the house and dug out the guarantee papers. Two year guarantee. I couldn't remember when I actually bought the mower so I had to search through bank records to find the receipt. That took a little while, but I found it. I bought the mower in August of 2019; just under two years. So I decided I'd have to take it back to the store. However, the store where I bought the mower is farther than our 10 km driving limit while we're under confinement. Curses! I hopped in the car and drove over to our local Bricomarché to ask them if they could do the repair or did I need to take the mower to the other Bricomarché where I bought it. I already knew the answer: I would have to take it to the other store. Ok, I thought, confinement is over on Monday. I can take the mower in next week.
Once home again, I got to thinking. I Googled Best Green tondeuse tractée panne de traction (Best Green lawnmower self-propelled broken self-propulsion). Up came four YouTube videos. The first one was a guy who was trying to fix the self-propulsion on a mower model very close to mine. One of the first things he said to do was to check the belt. Ken had actually thought it might be a belt issue; that was a couple paragraphs up.
So I went back out with my trusty tools (consisting of a ratchet set, a handful of screwdrivers, and a box of Allen wrenches), turned the mower over on its side, unplugged the spark plug, then got to work removing the blade. Once the blade was off, I could see that, sure enough, the belt had come off. After searching for the right size screwdriver, I finally got the belt cover off. The belt was not broken, so I put it back in its guide on the turning thingy (that's the official name for it) and reattached the cover and blade. After reattaching the spark plug, I started the mower back up. It worked!
By this time it was about 17h00. I decided to finish cutting the grass. And so I did.
I am extremely happy that I don't have to schlep that lawnmower over 30 km to the hardware store (and back) just for a slipped belt. And who knows how much time they would have taken to fix it.
