Racemower Build Part 1

Built a "racing lawnmower" for my senior project and this is the video I showed for the presentation. I crashed my other go kart, so I used almost everything I could from it in this build. It's not completely finished, but this is what I put together during the 2 week time window, in roughly 140 hours. I will be making more video-style updates when I complete it soon. More progress on the way shortly.
In addition, if you cannot tell from the video, this is not a real "racing lawnmower"used at actual events/tracks. Although I tried to keep it similar, it is not built to any race class or safety spec as an actual race mower is. This is moreover my take on a racing mower and will only be used around the yard and other like things.

Mac Demarco = instant thumbs up

[@jessesmyers1036]

Love me some mac dady

[@otmama2]

Very nice design for the trans shifter and steering! Looking forward to seeing the test drive .

[@Chamberfan]

Great work! Greetz from Germany

[@locedoutbiking2524]

Mac demarco makes it awesome and also thats one cool racing mower!

[@tylerbowers6378]

Have you ever found the top speed yet. Awesome build by the way. It does look like a brilliant idea.

[@adhd-motors3972]

I guess Im the only one that doesn't understand the gearbox situation how did you make the 90° gearbox work with the horizontal engine and axle?

[@thegenerousdegenerate9395]

So seeing as how this vid is roughly a year and a half old now, do you plan on releasing an update anytime soon? Even just a short vid showing where it's at now would be cool.

[@91forever]

great soundtrack

[@cheezblock4lllll]

Subbed for this vid alone wow 😮

[@switchjv]

nice job!

[@uvasam13]

+switchjv thanks!

[@moonman6154]

It's Brake damn it.

[@davidpayne4315]

I'm trying to build a tractor go cart just to go around my neighborhood and grab junk for my creations

[@AveryGaming12]

you should have put a little sprocket on the axel it gives your more speed

[@uvasam13]

Yeah, Ive been tuning in the final drive sprocket to get it to a speed I like

[@MrHotshot417]

Any running videos of it?

[@me_topher7241]

Why not make the front spindles adjustable

[@michaelmaher1845]

fire welds at 1:43

[@creel513]

sick work dude and names of songs

[@uvasam13]

+creel513 Thanks, songs are by Mac Demarco and Ty Segall

[@w.2.m.shoonigang198]

whats the 4th song called

[@uvasam13]

ty segall - fine check out his other stuff too. goodbye bread and manipulator are tasty good albums

[@PIGGY603]

ok thanks

[@szczygielski_3890]

What did u do for the transmission?

[@PIGGY603]

what kind of axle barrings did you use ?

[@uvasam13]

1" flange mount pillow block bearings.

[@tomscott3476]

Do a lot of the axle parts come from Northern?

[@uvasam13]

I used BMI karts because they have a little more selection. Cheers

[@PIGGY603]

+uvasam13 can i get a link for the tires - rims

[@uvasam13]

I bought them used off of ebay.

[@robertfleming1825]

what's the top speed on it

[@chetaoviet6253]

Where are the four wheels?

[@noeljalava7546]

Can I get the twin flat head engine?

[@uvasam13]

+Pyro Kanal Åland Its it pretty rough shape. One of the the header bolts is snapped off in the head, and the whole head, and intake mani, has oil in it.

[@SchulzChris]

Seems like a big lose of power to go through two 90deg boxes. Why not just run a jackshaft mid mower and be done. WOO has done it for years with horizontal crank engines.

[@SchulzChris]

@Jens Vincent Agreed

[@TeamUnknownRacing]

I really hope you don't plan on Racing it with those welds..... that's an E.R visit waiting to happen

[@uvasam13]

Haha yeah they're definitely pretty rough. I had no idea what I was doing back then, especially with 6011.

[@TeamUnknownRacing]

+uvasam13 hey. Gotta start some where

[@cooperscott6574]

getting a grinder for Christmas haha

[@kylepengelly8718]

What engine did you put in????

[@uvasam13]

"blue max" 6.5hp honda clone. Same engine you can get at harbor freight.

[@backyardmotorcross4092]

Why didn't you just stick with the v twin

[@uvasam13]

The motor didn't run, and I didn't want to spend money fixing because I already had the other motor laying around.

[@webhomemadeprojects1173]

need a video of u drive it

[@creativeexperience6388]

Yes Mac demarco

[@PIGGY603]

building one so ya im 12 and trying to get alot of info before i get into the project

[@jessemarchese7245]

PIGGY603;} I'm 11 and starting one too 👍👍

[@PIGGY603]

+jesse m wow gess we are both gear heads !

[@wolfnation9855]

PIGGY603;} how's it going so far? and I'm 14 and I already have one going but I'm keeping mine stock height, right now I'm working on getting the belt

[@sswolf7208]

Wolf Nation same, What is the base mower. the base of mine is a 1987 Snapper hi vac rear engine rider

[@devincap8248]

PIGGY603;} i have a full blown 45mph racing mower that sits 4 inces off the ground all it took was a welder and money im 15

[@FezSpar1fezIsee]

Let's see a test ride

[@uvasam13]

+Fez Spar soon!

[@ianbuilds7712]

why would u go through all that trouble with the peerless and gb if using a side shaft mini bike motor??? the vert shaft briggs that belongs there would make at least twice the power and tq stock nevermind the +30% parasidic loss u created with redundant power transfers. i got a 14hp kohler (modded over 20 ) 2 pulley manual belt clutch to a 700(input shaft supported) only better way is with a side shaft motor a single jackshaft then to axle

[@FezSpar1fezIsee]

Ok all take a test ride on mine

[@FezSpar1fezIsee]

I will upload my test ride

[@uvasam13]

Yeah I totally agree. Like I said in the description I used a lot of parts from my old go kart, including the engine. The original engine that came on the mower was toast, so I didn't want to have to hunt down and pay for another one. It was more of a project to see if I could repurpose all the parts into something else. The drivetrain power loss is pretty significant, but it is what it is. Thanks for the input!

[@kevinmiller2501]

is this really a slideshow this is youtube not PowerPoint

[@uvasam13]

wait............this isn't powerpoint?!?!?!?!??!?!!!?

[@itgetsbetter9636]

Wtf is up with the music

[@joshfinch2481]

Where did you get the steering column from?

[@uvasam13]

I think a got it on craigslist, but its one of those generic "weld together" steering shaft kits with a splined hub. This is pretty similar: www.bmikarts.com/Steering-Shaft-and-Hub-Assembly-Unwelded_p_4093.html

[@joshfinch2481]

Ok, I was wondering if you could get one with the bend in the middle pre made
