How to (or not to) change the blades on a Mammotion Luba! 

Thanks for the ‘honest’ example of how to (not) change the blades. 😊

I spray the whole underside of the deck, and especially the blades and the screws, with silicone spray. Seems to help when cleaning and the screws go in easier. Seems to make the grass stick less. Tend to fall off before it becomes a problem.

Sounds effects. Awesome. I know a good Foley Editor if you decide you want go another step up. But, you'd need a Foley Artist to create the sounds that the FE would insert into the video. Anyway, I am gonna remember this one. I found out yesterday that the house/property I'm buying, while 3.15 acres in total may only have 1 1/2 acres or so of grass. It seems a luba 5000 purchase might actually work for me. Fingers crossed.

I purchased new blades from Amazon ... Emberg blades... I was told they work with the Luba and the replacement screws with them are normal Phillips head screws. I agree... Hex screws are not a good choice. Also... I'm seriously considering cutting the side-shields down in size so they're about the same size as the newer Luba's side shields. Our side shields collect so much cuttings and if difficult to clean out. I'm sure making them smaller will help a lot. And finally... I ordered 2 plate covers for the blades. I have to clean under those blades now after every mow even when the underside itself is very clean. Grass cuttings wedging under the blades, and they no longer spin is a constant battle and I think that will really help.

Nicely done but always listen to Dad !

Nice! Been there myself once or twice.

I’ve been waiting to change my blades because I saw the video a few weeks ago that said you would be posting one. Then I saw the short notification got my tools and Luba. Watched the short and thought to myself “nope” not changing the blades until you posted this video.

Anytime a screw or bolt is hard to thread, work it back and forth. Also, add WD-40 or other lubricant. Don't force it. Also I changed my screws to generic pillipshead screws that fit my Automowers. Blades will work too. Many cheap options on Amazon. Trashed the guards and washers. Luba needs a free-spinning guard disk like Husqvarna to prevent the blades from jamming with debris.

i used my cut off wheel and sliced my blade guards off. I removed two bars on each side almost like your 3000. I made a huge difference on cut quality. Funny on the screws, as I get older it becomes more challenging to see the difference in some of those smaller screws! LOL

great work on the allen wrench

Love the Michael Scott clips lol,

I've gotten rid of all the hex head screws and replaced with philips head screws. So much easier to deal with, especially when the hex heads become debris-filled. The philips are easier to clean out and turn with a power driver. I'm also using vice grips to keep the disk stationary and not spin while I'm turning hub screws with power driver. I learned this trick the hard/painful/bloody way.

That IS embarrassing. But your humility made up for it...

Next time, listen to your father.

Kudos for showing the vid.. Also,, Dads are always right 😁 Regarding cleaning the underneath.. Do you have an air compressor you could try with a high pressure nozzle? That may work and also remove the risk of water ingress.

I’m thinking of buying two plates so I can swap them and change the blades more conveniently. Same as I have two blades for my Toro.

Loctite is fine once you passed the hard part like you were showing it should sit tight in half turn and its normal. Don't use lubricant or worst WD-40. I unjam before each cut and change them each week, clean them and shape them on the bench grinder. It makes a better cut when blades are free and sharpened)).

Do you change the battery yourself or do you have someone else change the battery?

I've been reading about people having water get into the RTK station and it breaking them down though some say they got there's dry and its working again... Have you experienced anything like this with RTK and has it rained hard on them at your families place? Thanks Bro! :) btw I think I might add clear sealant to mine around the led and round rim whenever I order and get my 5000... I just dont want any problems though maybe its super rare

Isn't the Luba blades spinning in both directions. What I mean is one time it would spin clocwise, and the next time counterclockwise. It seems from your video, I understand it only spins in one direction. That is a flaw in the design, as it will only wear out one side of the blades. If they would alternate spinning direction, you would technically only have to change the blades not every 5 months, but every 10 months.

Any update on the USB port?

My Luba 5000 came with phillips screws on the blades. Hmm...

Hello... welcome to the rest of the world. Hexagon is the IKEA key. Everybody everywhere has all sizes for free. Do not spray from underneath. Grab it with your hands.... for me dishbrosch.
