yard king racing/offroad mower build.

update:

fixed the intake with some exhaust sealer.



straight pipes(not done yet)




also sealed all the welds with the gungum exhaust sealer.

JB weld wouldve worked for the intake crack - ive used it to repair some small holes on a couple tractor decks as well.

Id probably go a lil longer on those exhaust tubes- i ran shorty pipes on my mod murray and the thing backfired /popped like crazy - it can eventually burn a valve - briggs motors like a little back pressure.

Im hoping this will hold up, but if it doesn't i will JB weld it.

The straght pipes are going to be a bit longer, problably exiting underneath the runningboards.

Cool - when i get around to building my rat rod wheelhorse i plan on putting pipes like this on it, cept a lil bit more under the foot rests :


( No this isnt my tractor)

Hey awesome tractor man! I just started mine today and have some of the things your doing and doing them on mine but I dont think ill put stacks on mine.
Awesome work, keep it up!

That is going to look slick, what engine is the rat rod getting?

Thanks alot.
Get some pics of your mower and post them on the forum. I would love to see it.
Im not going with stacks anymore, because of the exhaust fumes getting in my face.

That was a pic i found on a racing tractor website - altho i have a couple stock tractors of the same model.

My rat rod is going to have a 03 bolens chassis ( MTD) , and original unpainted rusty sheetmetal off my 69 raider 10 wheelhorse - itll be lowered, 8" golf kart rims all around, straight rear axle, and a 18HP twin opposed briggs - debating on wether to use a peerless 700 or right angle gear box with go kart clutch.

That bolens frame is going to be very strong and the wheelhorse sheetmetal is going to look sweet.
The 18 horse briggs are great engines. Are you going to do any mods to the engine?
I have a peerles 700 laying around, pretty strong transmissions. Ive seen people put little needle bearings in them to replace the bushings.
Its nice to be able to shift, and having lots of torque.
Right angle gearbox is easy to install and setup. But its more exspensive.

I have one thats stock that was on a mod murray, i ran it with the governer and it was scarey fast - i have another briggs 18HP that i was trying to set up dual carbs on to see if it even ran ( was missing carb and intake) , i bot a couple street scooter carbs at a flea market - i was thinking of hooking one up with a custom intake possibly. Its still up in the air what ill use on it.


I already have both - the 700 peerless and the RAGB - the 1:1 RAGB i bot off ebay for $25 because a pulley is stuck on it ( ill have to cut if off) .

Itll be a bit before i get working on it - i have a few other projects and stock mowers to work on first.

Dont think those scooter carbs will do. Ive seen people put snowmobile carbs on twins. Works great and gives them lots of power.

I bought my 700 togheter with a little RER rear axle with ballbearings for 50 bucks.
My toro groundmaster has a RAGB on the rotted out mowing deck. Im hoping i can save the deck, but if i cant save the deck i wil use the RAGB for a project or something.

When you do start to build yout ratrod mower, be sure to put it up on the forum.

update:

rewired the mower, extended my exhaust and started on my (piston) shifter.

push button start and on/off switch.




exhaust:










(piston) shifter:
piston from a 3.5 hp push mower engine.










welded a bolt to the shifter and i can just unscrew it when i need to take the transaxle out.

Slick looking exhaust! I bet the twin barks now.
You might want to make a skid plate or 2 to keep the pipes from getting damaged

Yeah its a pretty cool pipe setup - nice work.

Thanks. Sure does, sounds mean. Wil be putting a vid on youtube of it running.

The pipes are Made with very thick metal so i am not worried about bending/denting them. Just worried about breaking them off the engine or something like that.
Im problably gonna make some more supports out of flat stock and bolting it to the frame.
Skid plate is a pretty good idea to keep brush and such from the exhaust.

Thanks, followed your advice by makIng the pipes longer.
Runs so mutch better now, popped like crazy and ran like shit with the shorty pipes.
Also it sounds mutch better now.

Sander.

here is a link to a vid of it running with the straight pipes.

it sounds alot better in person though.

Nice setup it sounds great I subbed to you also.

If youre worried about your exhaust breaking an expensive fix to that would be flex pipe, like how they have on cars.

Actually, 18" of 1-1/4" flex cost me 6 bucks.

Is it really that cheap? Screw pipe fittings, im probably gonna pick some of that up when it comes time to do exhaust.

I got it from a place called Greggs Distributors in Canada. If it was that cheap up here it should be comparable there.

you'll have to look around for it.
Its Galvinized steel exhaust flex pipe.

I like it because it reminds me of the old classic cars like the buick Roadmaster

i'm going to get some flat stock this week to weld op some supports for the exhaust.
and im thinking of making a little skid plate.

That Yard King is a rare model. Made by Murray in the early 1990's. I have only seen 2 others in my 3 years of Murray research
