We have an EGO 52 cm lawnmower. It goes really well and we've had no complaints. However, in and ideal world, we'd like to mow just a little bit lower. We seem to have daisies that aren't getting caught by the mower on it's lowest setting. Has anyone here ever tried to lower the blade on their mower? Maybe by putting some sort of spacer in the blades connection to the drive shaft?

Normally a mower will have a height adjustment lever on the side that increases the wheel height relative to the deck. I wouldn't make any unsupported modifications to a lawn mower for safety.

Without being a smart alec, you could spray the daisies with a broadleaf lawn safe spray. Agree with Matt, you dont want to mess with rotating blades outside of factory settings.

Like other posters above I'd avoid any modification unless it comes from the manufacturer and is supported by warranty. I'm guessing they've chosen that blade height to provide the best battery life. Messing with it could put additional stress on the motor or motor bearings and lead to failure..

I'd suggest a call to the manufacturer support line and see what they say about the issue. After that I'd go and have a chat with the retailer about the issue. If neither of them has a suggestion I'd ask them to provide a favorable trade on a suitable model.

That's actually a good point. Our lawn needs a bit of weed control etc anyway. So, I guess we could get rid of the daisies. Our previous petrol mower cut lower, but if it wasn't for the daisies, the EGO height would probably be OK.

You should set the mower to be a bit higher thus keeping your lawn longer. Longer grass discourages weed growth as the lawn mass gets denser. This also has the benefits of improving moisture retention and making the lawn nicer to walk and sit on.

Here is a crazy notion, lets give peace a chance.

I have the same issue with my milwaukee mower - even on its lowest its way too high and leaves too much grass.

Occasionally I bust out the old masport beast which is amazingly still running with only having its oil topped up when I can be bothered, and it goes lower. Once you get a thick grass the wheels are lifted by it and you need to cut lower to be actually cutting anything I find.

I have no idea what sort of grass my lawn is. Its just something that I have because concrete is expensive and council say no to 100% coverage.

i'll bet your old lawnmower(s) where kiwi brand not usa like ego and milwaukee.

kiwis tend to mow down to the dirt so hence the wheels height adjustment allows a very low cut. usa uses a cut height that allows grass to grow. for eg max height on my masport is about normal height for usa. my neighbor actually mows dirt. so its not a mower problem rather a "kiwis like to cut grass way to short" problem.

if you want to mod anything, mod the wheel heights. the blades actually need to sit in the body at a certain height for air flow and grass clippings flow reasons.

Agree, Kiwi bowling green mentality!

Most NZ lawns will be growing in a boggy substrate of thatch and are in desperate need of a really vicious dethatching with a scarifier or coring machine.
