On my new ExMark Lazer Z zero turn with the 60" deck, I noticed my striping wheel wasn't marking the lawn when I was mowing today at my neighbors. Then I noticed this;
Normally, you stand on the deck on a special non slip plate when getting on and off the mower. When I step on the deck normally, it's doesn't flinch or move at all. It is rock solid.
Today, when I got off the mower to see what was causing the striping wheel to not engage, the deck was able to be tilted slightly when stepping on it. Also, there is a pedal which lifts the deck for transport and locks it in position and that pedal wasn't functioning correctly and wouldn't lock the deck in place. The reason was the rear lift arm wasn't allowing the deck to lift high enough to permit the deck to lock up in the transport mode, which is also where it needs to be when setting the mowing height from the drivers seat.
This one little issue sure prevented everything from working as they should. It took me longer to post this than it did to repair the deck and put it back to it's correct position......
Once I jacked up the side of the deck where the chain was bound up, with a floor jack, I could release the tension on the chain. I had to use an impact gun and take the bolt out of the chain and then reinstall it as it was bound up and I couldn't get it to move with a pry bar and I didn't want to scratch anything.
I stopped by the dealer today, who is a good friend, and The dealer told me he has never seen this happen and the factory rep happened to be at the dealership at the same time and he said the same thing. The odds of getting the bounce in the deck (it alone weighs over 425 pounds) and to land in such a manner as to bind the chain has got to be very unlikely.
I used a floor jack and lifted all of the weight off the deck and used an air impact gun to back out the bolt so I could unbind the chain. Once everything was straightened out, the bolt was reinstalled and the other 3 hanging bolts were all tightened about a 1/4 to 1/2 turn to remove any ability for the link on the bolt to rotate as it did to cause the bind up.
Live and learn...... It was a very easy fix, just couldn't recall the bump severe enough to cause this to happen.........
ExMark uses a very simple and tough system to hang their decks. And other than this weird incident, it provides a perfectly level cut and with the striping wheel, which you can see on the last photo on the back of the deck, it provides a really nice finish. Plus their deck is designed to be stood upon to get on and off the mower, which takes some getting used to after years of stepping over the Deere SCUT and Lawn Tractor decks so as to not disturb their levelness.......
Another very nice design feature is that the large pulley / belt safety cover can be removed with one hand and no tools to permit you to use the back pack blower to clean the deck really well. I can remove the cover with my left hand while using the back pack blower and then reinstall the safety cover, just that fast. It snaps into place and is very strong, yet easily removed. That is a great design feature for really keeping the deck clean after every use.
ExMark also uses a very deep (tall) deck which creates a lot of extra lift for excellent cutting. They also have a very high blade tip speed when cutting. While the zero turn is pretty much a single purpose / task machine, this ExMark Lazer Z does that single purpose / task of mowing, extremely well.
I have been extremely pleased with this machine. I already have 80 hours on it since last September.
Check out this new BEAST from ExMark in the attached video it uses the Yanmar in their 96" zero turn rear discharge mower. My dealer friend has 2 of these in stock. Retails for about $45,000 each. He will sell it for $39,900 plus tax. Hydraulic lift and angle bat wing mowers. Really nice mower that mows 12 acres per hour................
