Off Road Mower Motor Swap part-2

[@offroaddomination5708]

That thing sounds so cool with the intake sucking air!

[@dylaneagleton3090]

It's pretty normal for an ungoverned engine

[@Fearlessfront]

Off Road Domonation Yeah it does!

[@offroaddomination5708]

FearlessFront (Todd Christopher) hey one more thing what is the pully ratio on this tractor and how fast does it go

[@cheezyz861]

In later vids he sais it goes 20 to 23 mph :)

[@kevinwitt6369]

Fearless when u r goin backwards on your track that fast when u do a hard turn u r slinging the oil toward the crankcase breather it be the same as if u was mowing on a hill...... Worked on small engines for 25 years

[@Fearlessfront]

Kevin Witt Yep, exactly. With the catch-can on there, it doesn't do it anymore

[@kevinwitt6369]

Cool like your vids alot keepem coming

[@starpuss]

*Sounds good!!* But that thing needs a Vtwin :)

[@MrTheHillfolk]

Yea that's what I ended up doing. Actually I was all lined up to swap a 14.5 ohv from the 12 flatty it had when I came across the 20hp v twin....figured more is better :) Looks good there fearless...as it's always a work in progress, you might wanna wrap that exhaust with (lol) exhaust wrap to keep the radiated heat down... Good stuff.

[@MrTheHillfolk]

Here's another strange tidbit that happened in my swap.... As soon as I got it running, my neighbor came over and wanted to know what I did because it was a lot quieter than it was with the 12 flatty. He said it wasn't the exhaust note, but mechanical noise quieter. Both had the stock exhausts that they come with too.

[@TheBettereducated]

Vtwins spund amazing

[@MrTheHillfolk]

+OffRoadWreckin2003 Yea of course I had to test run it with open pipes , that's mandatory! I'm not a big Harley fan but I dig the smaller vtwin (Briggs ,etc) sounds.

[@ferdinandhazelhorst3808]

I am Dutch and my lownmower runs 21 miles

[@tmytco7664]

Cool stuff. That thing moves pretty fast for a first time out.

[@WeldstarCreations]

Nice clean install. The exhaust sounds great. That engine really breathes!! I really like your GoPro coverage. I get a feel of what it is like to be actually driving the Murray. A definite upgrade.

[@Fearlessfront]

WeldstarCreations Thanks! I like it too! It hauls ass!

[@PaulieDetmurds]

So fun to watch your vids, hell, I am 53 years old!

[@jameshutcheson7677]

she sure loves air you can definitely here that but she sounds good man but I have a question should I locker my trans axle or not what do you think

[@ZrubekFamily]

Reminds me of the old Quadrojets when them huge back barrels opened up!!

[@quickzztopp-5767]

Hell yeah, this guy's nuts!

[@mikemarkes4100]

love the vids have you ever thought about some sort of suspension for your mowers,just curious as to how it would work

[@focustuner10]

That thing sounds freaking awesome!

[@williamgoring7605]

I think that's so cool I'm doing that same thing with an sst15 John Deere because with that mower it's it's very high off the ground if you look up that model you can see without the deck it's fantastic and it has the hydrostatic rear end in it so it's going to be really fun at on a track I've got a 15 horse on it and I'm going to take the governor off it and we'll see what it can do out there it already cut the grass really fast but I've got two other lawn mowers now thanks for the video and thanks for the ideas now I know what I need to do to get this thing track ready

[@prancstaman]

Still sounds the same, which is good and mean. Thanks again for the stickers.

[@zachsgarage4714]

That's ohv power for you.

[@zachsgarage4714]

Yee Yee.

[@prancstaman]

Did you check out my vid yet on fixing that problem with the pvc valve cover yet? It shows how to modify the pvc valve cover so it won't puke oil any more by keeping the oil in the motor. That thing is sucking air like crazy man, Is that a stock motor with no porting?

[@joshuahenrichs595]

Box cutters make the best screw drivers

[@johnathanringstaff5176]

Fearless man i just turned 16 and watch all ur videos love them man I actually got the idea to make my lawn mower like urs but it broke and its gone I got to get another and get tips and help from u to make it great

[@Fearlessfront]

Johnathan Ringstaff thanks man, go through some of my older playlists, there's lots of tips/how-to's there

[@johnathanringstaff5176]

I know I love em that's what I did the first time like I said I watched all of them waiting on u to put more videos on and what have u done to the four wheeler been waiting on that

[@Fearlessfront]

Johnathan Ringstaff Nothing yet, but I think I'm going to try and fix it

[@johnathanringstaff5176]

Ok that sounds cool

[@jacobkirtland8473]

+FearlessFront (Todd Christopher) what is the pully racio

[@Markrunic]

Hey Fearless, do you know how much torque these ohv engines produce? I have a 15.5hp ohv Briggs, not sure if yours is a 14.5 or a 15.5. Love your videos by the way, keep up the good work!!!

[@davekorn6516]

Fearless what pulley swap ratio you running got 2 craftsmans for free engine pulley is a 3 inch but would require 2 much modifications with the clutch to go bigger on the motor what size should i go on the transaxle 2 get some speed without getting belt slippage transaxle pulley is an 8"

[@tristanlamb822]

I watched all your videos....love the Murray....this poulan isn't locked so I have no idea why it won't bog down so it will sling mud help please

[@rogermountpleasure6260]

this lawnmower is the best!! whats the top speed of it?

[@sambaker31]

Sounds good love to see a top speed on the Sears making a Sears my self love to see how fast yours go's

[@offroaddreams477]

Not bad at all can't wait for mud romp with motor swap see how she works under a load in the mud lol have a great day

[@Fearlessfront]

Matt Blankenship Thats the next video!

[@leanneray4741]

now your tractor is just like mine. lol Glad i found your channel, thought i was the only one who did this stuff. i'm in Tennessee, and would also like to thank you for the stickers. keep it up dude

[@Fearlessfront]

Superscott Wyatt You're welcome!

[@26PaulyC]

Sounds like small 4 barrel when on full tilt ,nice build

[@AlanCSXFan]

That sounds AWSOME!!!!!!

[@kylerichardson2742]

Huge fan of you I have an old Sears I'm trying to build right now but I am moding it to fit an old Briggs 16hp horizontal huge engine have to make a hood scoop and brackets to make it fit

[@blairpryor1248]

that was the best sounds from a mower

[@9102jack]

flathead to ohv.... it's like going from a 250 twin elan or 340 olympic to a 583 formula or 617 mach 1, something you can actually feel and hear the power you're putting down! Doesn't feel like it has to struggle to move around anymore!

[@HippyDave57]

The intake sounded like a small 4bbl opening up! Haha! Good job!

[@Fearlessfront]

HippyDave57 yeah, kinda does!

[@9102jack]

+FearlessFront (Todd Christopher) hotrod!!!!

[@mrwtfmate100]

Sounds fantastic man

[@wyattstock6661]

nice have the same motor I am thinking of doing the carb change and air intake thanks for showing that

[@olpaully9646]

FearlessFront (Todd Christopher) I'm working on a mud mower it's craftsman 22.5hp vtwin kohler command but it seems like it's choking itaelf out, running real shitty I've cleaned carb, replaced air filter, fuel filter, cleaned gas tank and new gas lines and tried tweaking with air/gas mixture any advice?! Huge fan

[@bradymorrison2117]

I was wondering were u get your kids tires at bc I can't find any that more possible fit on my lawn mower

[@droptheblades895]

whatever happened to that flathead? sorry if I've missed a video with it past this point but love the content

[@luigiprovencher]

Is there a part three to this or what's the next video for this particular machine?

[@Countryboy7213]

Hey fearless I've been watching your videos for about 3 years and your actually the one who got me started with offroad lawn tractor and I started my bicycle brake handle gas petal got it welded to floor every thing is ready but I'm have trouble hooking it up. I was wondering if you could may a short brief video on who you done it? Thanks

[@Fearlessfront]

Countryboy7213 I'll try and do an install video sometime soon

[@Countryboy7213]

Thanks It would help a lot appreciate man

[@rex4x4]

jeeze ...... all that smoke reminds me of when i went to visit .

[@Fearlessfront]

Rex4x4 lol! yup! I guess I should have put the catch-can on in the first place!

[@peterlombardi2263]

lol I thought I was the only guy who did this too with my modified crafts lolololol

[@rncboy2]

What did you mean by time out I have a 11 horse ohc haven't been ran in a year still trying to get pully off trans axle and I was wondering where to get a different belt not sure if tractor Supply sells larger belts

[@bullseye1263]

Have you thought about putting a set of rear dual tires on any of your mowers

[@jgraan]

Fearless I am such a huge fan! I would love to get a lawn tractor and pulley swap it but my parents won't let me. Anyways I have a great idea for you. I've heard you can find very small turbo for engines like your own and you should turbo charge the murray!

[@Fearlessfront]

jj graan I donno, forced induction is more effort than its worth. plus I would have to figure out a way to pressurize the oil system to feed the turbo.

[@jgraan]

Your right I don't all that much about turbos, it seems like you know more than me, thanks for responding my comment.

[@Fearlessfront]

jj graan NP!

[@lukerussell2990]

I personally like the flat heads better than the ohv! Flat heads are literally invincible! Just my opinion, lol

[@hillbillyfishing4317]

Just getting into the lawn mower customization thing, How did you manage to be able to change gears?

[@hillbillyfishing4317]

Thanks

[@ianbuilds7712]

The way u run this tractor l think u need to gear it up a bit more theres no need to rev that ohv so high it seems like they make power a little lower than the flattys at least with stock cams... I think just another inch bigger on the motor would b perfect and would make the motor last longer... also I wonder if the flat head cam would work on an ohv...?

[@deshawngarner4691]

Hey when do you think you will take it through the mud again? And could you do a video on taking a starter off of the Murray ?

[@mowermadnessmoen1570]

Love it dude I used to have that motor I should of kept it but who cares can always find a new one

[@SonnyGTA]

you have a great area for that stuff!!!!

[@xtrememachines9336]

Bad ass I love the new update and videos

[@ericneeley7752]

Hey fearless, your videos are awesome man, keep it up, need more tho haha

[@noone42069]

sounds like a quad haha! thats awesome!

[@leviashbrook8152]

Hey FearlessFront (Todd Christopher) where do you get your transaxle pullys because I need a half inch one or a little bigger

[@WilliamSeibertwillis923]

sounds like my wheeler intake with the K&N filter and airbox lid off

[@tristanlamb822]

The tires on it has thick thick tread could that be why....also when I'm in 5th gear and I pop off the clutch the damn thing always catwalks...how do I get it to where it doesn't do that

[@zachsgarage4714]

What is the spark plug gap your running in your ohv briggs.

[@rev9fan1]

Ha-ha I second the turbo charged idea!

[@wood2hoz4]

Man that intake sounds bad ass!

[@tristanlamb822]

Fearless....umm I have a poulan mower...i cant get it to sling mud....I'll try to and the tires I guess get to much traction..idk help

[@jimsoutdooradventures2748]

Sounds Great, I hope it holds up!

[@Fearlessfront]

jim ogle me too!

[@leviashbrook8152]

Hey Todd I love the sears and all ur videos they help me out a lot I wish I could meet u and wish I could lock my transaxle

[@Fearlessfront]

Levi Ashbrook Welp, I live in Maine, drop in if you're ever in the area

[@danielrichard4512]

I really like what your doing with your tractor, but i think ill keep mine to work arround the yard. Daniel!

[@travis4798]

Did you put your 12hp carb on the 14hp ohv? If so it might be the wrong cfm. That would explain the random air sucking sound.

[@harryjlegg]

+Travis Piper I think he's using a 17hp carb so I dont think it would be that.

[@travis4798]

Harry Legg Ok, wasn't sure.

[@woodman1241]

it's prob just cuz intake is so open there's no air flow reduction. I can hear the same thing on my car

[@gt20modding88]

He has a K&N on it.

[@jason2222ism]

i have a question for you. why keep using belts and pulleys for the drive train? could a person not use a comet industries tav2 torque converter and chain? I use that on my Baja mini, is there something im not thinking of? thanks

[@alancampbell1633]

jason2222ism the chain would fall off.

[@gt20modding88]

Chain tensioner.

[@bluejayshatrau]

Hey Fearlessfront i wonder how mean that murrey would be if it had a v twin with in its body

[@CadeIvy]

Have you ever thought about putting a briggs v twin on the murray?

[@xgames7136]

nice mower and where did you get the knife at

[@MTD12HPTURBO]

Looks Good bro

[@jeremymcfarlane1781]

#fearlessfront do u still have the one mtd that had the wicked straight pipe coming off the motor

[@brentunderwood7600]

what are those things called that you used to pinch your throttle cable together at carb?

[@nickolausvandever-moore2708]

that speedometer app is awesome I used it to figure how fast my mower went and it read the same as a police speed gun

[@robertsell5591]

Hey fearlessfront do you still have your fourweeler the blue one if you do would u be interested in saleing it?

[@9102jack]

I propose a fix for the excess pcv oil flow: install a separate pcv breather line with a fuel filter on the end [like the gokart mower]. Leave the plastic on the end. a clear filter will allow you to see oil/grit. Since you push these mower engines to ever higher rpms and g forces, the intake vacuum [BEFORE THE CARB] is a bit higher; a 465cc engine moves alot of air at 4500rpm compared to 3-3600, especially with valve overlap and a free-flowing exhaust. Your air filter's natural restriction may be enough to overwhelm the stock pcv reed valve [in the lifter box beside the carb], drawing more flow than normal.

[@Bign89]

my ohv 14.5 it didn't like to be bounced alot or high revved for long periods of time when it did it smoked just like that

[@jamespitts9402]

Have you ever thought of making a pully system with 2 belts double the traction???

[@fearlessbuddies2837]

When u stopped to put the wired mic on the stock throttle location, I honestly thought the murray still had the 12.5hp engine not the 14.5 hp ohv

[@robertsell5591]

I've never owned one before but would love to

[@wademckenney6858]

How do u get the lawnmower to go fast like that its acting like a fourwheeler

[@willkemp5139]

sounds awesome is what it sounds like Lol nice tractor BTW

[@scratness1036]

can you do a build on a craftsman hydrostat lawnmower. that's the kind of lawnmower I have and I don't know how to turn it into an off-roading buggy

[@erikkvam1081]

that sound is awsome

[@thomasmorehouse9277]

good job FearlessFront (Todd Christopher)

[@motorider4935]

damn thats sound AWSOME and what a freakin awsome video love it it alot i have the same mower as u but its stock i wanna upgraded so it will go faster

[@leedemarsh3159]

Do u still have stickers FearlessFront (Todd Christopher)

[@joshuabeanblossom8371]

my old allis chalmers b112 lawn tractor has a flat head single piston engine on it and it's a horizontal shafts engine not a vertical that goes through the frame so how could I make that faster?

[@alexhickey5633]

Joshua Beanblossom take the tranny pulley off take the engine pulley off. Put the tranny pulley on the engine and the engine pulley on the tranny. This should work and you wont need to get a new belt

[@NickMartin9915]

you should re-do the truck pull test with the new engine

[@greenwaylawncareandlandsca2961]

Sounds great.

[@slimline65]

Sounds awesome

[@calebkeel2492]

where do you guys find your mowers at?

[@steven7554]

Cool man she will do about 21mpb i got the same set up. And know you can mod the motor it being ohv

[@smoke_me_broke_pulling_team]

hey fearlessfront do you still have any fearless stickers

[@smarttila4848]

Is a brigs v twin ohv 14 hp a good motor on a craftsmen

[@DCopp]

[@naviotlink2117]

[@jacobdavidson6571]

accessories etc headlights

[@ryansmowing1]

Whats that app that you use for the speedo

[@garymathews9534]

you need to build a banked oval ,like a small dirt track .how about a home built track buggy ?

[@stevelamperta865]

i have a 25 hp v twin john deer tractor and the only thing i want to do with it is mow the lawn and yard work ! I have a 660 yamaha raptor when I go trail riding !!
