I've been push mowing my yard for a few years and I'm finally over it. Decided on a 36" SCAG Liberty Z, which I hope will last me a long time. Looking forward to getting it delivered tomorrow.

Before these last couple of years, I had a guy cutting my grass for a while, but I honestly like maintaining my yard myself. It also gives me a chance to look at the condition of everything around the exterior of my house and yard.

Anyway, I'm sort of clueless on routine maintenance I'll need to do. Obviously I will take a look at the owner's manual, but curious if you guys had any tips from your experiences.

go get a grease gun
go get a set of chocks, or a chain fall, or some jacks so that you can change the blades

That's a good point. I'm clueless on how often I'd need to sharpen or change blades - or what indicates it's time?

not sure about the liberty but on my turf tiger you have to raise the mower up all the way on the rear tires. i use a chain fall to crank it up

I'm just busting your balls, and maybe a little jealous. I'll live vicariously through you til my old john deere finally goes to that big pasture in the sky and i can upgrade to a 60" soft suspension beast...

Always keep a spare belt, set of wheel bearings, spindle, idler pulley.

Buy a grease gun. Depending upon your motor, I only run 15w40 rotella in the old scag with the kawasaki. Only run mobil1 0w40 in anything with a briggs motor.

Check your filter, you can get oversized versions with the same flow rate and bypass pressure for usually 20% of the oem filters.


I change air filter, deck belt, and blades once a year. But I'm mowing about 1500 acres a season. And I don't stop for anything short of a concrete block

When you finally kill the front tires... Go solid tire. When you finally kill the rear, get some with grip.

I spend about 150 bucks a year on maintenance. Spindles last 3 years or so.

Proper zero turns for home use are the definition of overkill. And it's great.


Even I just question the downvotes?

You can fix anything on a zero turn that actually breaks in under an hour as long as you have the parts on hand. Keep the things I have listed and your mower will never be down for more than an hour. I don't even keep spark plugs on hand but then again I do run wide open throttle.

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.

Thin oil or thick oil?

3/8 cordless impact is great for removing and installing blades

20W50 Motor Oil in the Kawasaki Engine. 20hrs for break in and 50hours or once a year for reg oil changes. Spindles are sealed bearings so you pretty much just run the until they're screaming then replace the bearings. Change the air filter annually.

Keep the deck clean, blow it off after mowing and just make sure it's not getting clogged underneath with wet grass. You can probably just change the blades once a year and you'll be good.

The Liberty Z is an awesome residential Z and has so few issues that bring it back to the shop for repair. You'll be happy for many years with this purchase.

Thanks for the advice so far everyone!! Certainly helps to understand what I should be looking out for.

The sales guy said the same thing. He said they rarely see them back in the shop for repairs. I’m hoping to do my part to make sure it stays that way.

Change the engine oil in the first 10 hours.
Every 50 hours thereafter.
I would recommend Kawasaki 20w50.
Shot of grease in fittings at oil change.
Inspect/blowout/replace air filter.
I have a Scag Patriot with 300 hours and it has been trouble free. I have sharpened/replaced the blades many times.
Still on the same belt.
Take covers/guards off belt pulley’s and blow out clippings off top of deck and belt run.
