re: Bought a SCAG Liberty Z This Morning - Delivery Tomorrow. Maintenance Tips?

Not sure how the blades are fastened on the Scag, but on the Gravely, it's just a large nut. Get a pneumatic impact or one of the heavy duty battery impacts to get them on and off. A normal screw driving Dewalt impact won't budge the nuts. If you try to use a wrench, you have to figure out how to prevent the blades from turning while you loosen the nut. I'm able to pull the blades and sharpen them, then put them back on in about 15-20 min.

You need to sharpen them when you notice stragglers after you mow. My lawn mower was so dull I might have well been mowing with a spinning piece of rebar. After sharpening them, nothing is left behind. I have rocks in my yard and sure as hell hit one about every time I mow, so I had to get efficient at sharpening.

Other than that, just stay on top of the maintenance oil change and air filter cleaning. The Kawasaki engine on mine has held up well for about 8 years now. Honestly wish the thing would bite the dust because I want a suspension seat and I won't put one on this mower. I get beat to hell on my property and it takes about 2 hours of riding that thing to get the whole property mowed.
