donor mower

[Rotore]

i got a riding lawn mower for $100 with a a 11.5hp brigggs and 6 speed tranny... (i could of gotten a 4hp honda horizontal shaft for the same price but no recoil blower housing)

But thats not the point i want to know if i can use this lawn mower as somewhat of a donor for my go kart? Like the spindals, steering wheel, tranny, engine ect ect

BTW i think it was a racing lawn mower... i'll put pics up soon

If its the stock stearing setup, and stock spindles, no there very weak. You can use the 11.5 briggs and 6 speed tranny if you want, but race prep the tranny and dont gear it for much higher than 20mph.

I just picked up a mower today too! 6 speed tranny, 12hp kawi. $10. Heres my thread. http://www.diygokarts.com/vb/showthread.php?t=3731&page=3

Now lets see some pics of yours!

that sucks thats exactly how much i pulled on it 20mph lmao but yea so i can use most of the stuff on this mower except the spindals since they are bent anyway...

i'll see if i can get it somehow in my backyard tomorrow and start piecing it out.. i'll post piks

Btw nice mower but whats up with the front end?

It snapped off , the previous owner hit it with a sled hammer ... If i were you i'd just make that into a nice offroad/racing mower.

i'm in the city the nearst off road coarse or place big enough is an hour away besides i bought it as a donor for my cart..

Btw I have a few questions...

*do you know how i could l mount some kind of shifter for the tranny?

*can i mount the tires direct on to the axle like on the lawn mower but using smaller tires?

*what size are your rear tires htey might be the same size as mine?

 

[Kaptain Krunch]

My tires are 18's, not sure of width... once you take the tranny off you will see how easy mounting shifter linkage is, and there are infinite possibilities for linkages. and yes, you can mount the tires right on the axle, but like i said before, race prep the tranny and dont gear it too high.

kaptian i took the tranny to school to prep it up with some steel gears we had in the shop and found that its already been race prepd.

Well yesterday i couldn't get much done but today i got the mower stripped down to bare bone (literally) not so bad if i say so myself. i found that most of the gears on the tranny are useless except 5th and 6th whose gear ratios ar 7:1 (5th) and 5:1 (6th). i'm kinda surprised i got all these parts for a $100

*Steering wheel
*seat
*6speed tranny
*11hp engine w/ starter
*belts
*wiring harness
*kill swith
*battery
*Spindals
*tie rod
*pulleys
*nice set of tires
* and best of all a cool idea for the frame

but im still missin a bar for the steering, pedals & cabels, frame (which will be made soon), belt tensioner and some misc. stuff. i doubt this build will go past $225


Other than that i have some questions

*I found that the tranny is a disc and caliper (brake) on the side, i was wondering if i could tap into it instead of doing a seprate brake setup?

* can anyone point me to a picture of a tensioner or something..

Here are the pictures i promised and a rough sketch of the frame design:

*BTW the design is for a front mount engine and yes i realized it wasnt a good idea this mornin i'll work on the design later on tonight*

First off, dont use the tie rods, there weak and can/will snap from normal steering stress. Second, the brakes are also a bad idea. They dont lock up too well at high speeds, and if the tranny cases split, or you strip a gear you lose your brakes too.

I can get you a pic of one of the tensioner's off one of my mowers if you want, but didnt yours have one?

Did the previous owner race prep the tranny well? (lock the diff, permatex seal, breather, etc.) Also what model tranny is it? im guessing 920 series? definitely be careful with that, there not the strongest.

just gonna use the kart for cruising so i dont think that it'll be much stress on the brake.

and yes lock diff, seals breather the works the eninge even came with a custom exhaust that i'll have to redo lol..

but yea my mower didnt have one just the belt (no wonder it slipped alot) if u can get me a pic it'd be greatly appreciated.

I'll have to get them tomorrow when its light, cant get a good pic with the dark garage and crappy camera phone.

I'll get right on it, whats wrong with the exhaust?

weak welds and i dont need an exhaust pipe leading into my ear on the kart
