- So I have been meaning to film this thing. It’s just a low budget project. I’ve always had a thing for lawn mower racing. To me it is an excellent sport. One of the cheapest sports to race in. anyway this is a quick rundown of the budget mower. As the upgrades come in, I’ll be sure to update you guys with some videos. Thanks for hanging out! Please like and subscribe. It’s free. Also peep some of my other videos!

I love your ingenuity fixing it up! From the linkage to changing the shifter leaver :) that’s pretty awesome.
Thansk man!
Very cool seeing the old Murray's still in use, thanks for a speedy ride around the block. 👍
That’s awesome buddy I love it!! I love the old school trackers!! You did an awesome job on it!!
Thansk man!
Just got me a 92 for free and I fucking love this.
You just solved my transmission lever issues thats awesome, u didn't explain how to do it but I paused the video and seen how u did it ...awesome job
I’m trying to figure that out still lol
Bad ass grass rod build my man!
Hell yea! Thanks!
Looks like fun
Spiral diaphragm for the carb, I’ve haven’t used on but they are swore by. and go to the other side and roll the check flaps, on that gasket, to press real nice on the carb’s ports.
What?
Hey mate could you show us your shifting set up seem pretty cool got the same mower and would like to change my set up to something like that could you do a video on it plz
I've got a simpler/cleaner way of attaching a throttle cable to the stock governor linkage if you are interested in building another.
awesome video, im actually using a Murray as well mine is the briggs 16.5hp one OHV iron bore wouldn't mind trying to do the pullyswap as well. right now going probelm after problem smh , first was all the belts ground and deck, then gas tank was leaking now starter smh :/ but i still love the old Murrays mine was the model 425009x8
I just got a murray as well, Briggs 12.5hp, tied a wire to the governor so it will pop wheelies and planning on swapping both pulleys, gotta fix most of the wiring to the battery and solenoid though, it's gonna be a fun project
How do u bypass govenor
I freaking love it! Go, man go ha ha ha ha ha ha😂
I like a guy with old bay seasoning, lmao
How did you do the shifter linkage?
For the throttle you could have just by passed the old system and tied your cable straight to the governor arm. That would be a night and day difference and you should get full rev rang from the engine. The engine has a max rang of 4300rpms. So you so far unlocked like 2500rpms.
So 27mph would be more like 34mph.
Yea I’m aware of how to get more out of it. However with the stock connecting rod, valve springs, and cast iron flywheel, id like to keep the rev range stock lol. It’s super reliable right now. But I agree I can get a few more mph out of it. I have the idea to tie a string to the throttle arm and get those rpms when I need them with a quick yank lol.
Those Murray’s are tough
They sure are!
Are you by any chance from Maryland?
the year of the frame can be a few years different from the motor (even for its original motor). this was the first vid I found that told Me that the code is the date of manufacturing and it's been so usful.
I agree I've looked everywhere for the label under the seat for my Murray. I guess it rested off years ago. The original owner said it's been sitting there for close to 15 years. Turns out the engine was manufactured in 1999. Guess it's good enough for a ballpark figure.
Nice! Is the transmission still working? Want to speed up mine too, but I'm not so sure about the lifetime... I mean you hear it screaming xD lol
It’s still working to this day. I try to take it easy. I don’t like to shift it too much. It’s a fun little toy lol
@@aaronpratt89 can you send me the pully you bought? I can't find something that fitts right on that thing. Thanks! and the lenght of the belt?
@@DeutschlandLife the pulley for the engine is 4 inches for a 1 inch shaft. The trans is a 2 inch for a 5/8” shaft. I don’t know the belt size. I bought a bunch and the one that fit is the one I kept. I returned the others. A custom clutch was built also to work with the new pulleys.
@@aaronpratt89 Now, after 5 Months, the Murray is driving :D Well, the Clutch isn't ideal. Want to build it like yours.
@@aaronpratt89 Hey there, put on the engine a bigger pulley and a dual clutch like yours. Drove over 21mph and can still go faster, but my road isn't the best for that speed. Upload a video soon.
I got the same one except its 11 hp
Where did you get that Rear Pulley?
Tractor supply
What size u run on front and back?
I believe I mention it in the video. It’s 4” on the engine and 2” on the transaxle
That power shifting probably isn’t the best for that unsynchronized transmission lol
Bro it for sure is not lmao! I am impressed on how long it has lasted at this point! It’s a trooper for sure!
Is it best to have small on the back and big on the front?
Yes, from the factory the small pulley is on the engine and the large is on the transaxle. You want to spin the transaxle faster to increase the speed of the machine. Only way to do that is to change the pulley ratio. Search some pulley ratios on TH-cam. I’m sure there is a video to help better explain it.
@@aaronpratt89 so small on back big on front basically
@@northernrips9959 yes
@@aaronpratt89 ok thanks
@@northernrips9959 you got it!
i have one just like it
what size pulley?
Engine is 4.5 inches. Axle is 2 inches
how many inch backpully?
2 inches
Do you need new drive belt if u swap it
Yes! Due to the smaller pulleys a new smaller belt is needed!
@@aaronpratt89 What is the size i have same lawnmower
@@jerolehmuskoski5108 I don’t remember what the exact size is. I cut the original belt and used it to measure for the correct belt. The machine is packed away at the moment. I am moving and between houses.
What rear end do you have in it?
The original transaxle. It’s only a 4 speed.
@@aaronpratt89 well I am doing a build and I need to get a rear end for it
@@brianmills8977 I can take a pic of the sticker on the transaxle if you need me to. However 99% of these trans axles are pretty close to the same thing. All of the ones I have built all have the 5/8” input shaft.
@@aaronpratt89 yes please take a picture
And I think we have to same lawnmower
The transmission doesn’t sound too happyWhen you let off the gas
It is absolutely pissed off! These have strait cut gears and no seals on the shafts. So from the factory they pack them with grease. Well, I pumped a quart of oil in it to help it stay alive. I’m honestly suppressed it has lasted this long.
@@aaronpratt89 yeah
Is that the stock idle?
I did lower the idle a bit.
@@aaronpratt89 did you adjust it via the carb or the governor?
@@CamoCollie governor doesn’t have actual control of idle. I adjusted the idle wire screw on the carb. When adjusting the idle, don’t go too low it won’t charge the battery. Use a volt meter on the battery to make sure you are still charging.
27 is fast for a lawn mower, my fourwheeler wont run that on a good day, it's so worn out
Hell yea thanks! I can add a bigger engine pulley and get some more out of it. But I don’t think the transmission is gonna last much longer lol
@@aaronpratt89lol I'm buying a horizontal shaft mower in a few days, saving it from being crushed, I may do a predator 670 swap, but I think you should find a 20 horse vertical twin if you want that thing to really fly
@@t-dogracingandoffroad3198 I have a 22hp that I want to slap on there. I also have a 16hp that I want to turbo lol
@@aaronpratt89 lol nice I'll be tuning in for whatever you have next for this thing
@@t-dogracingandoffroad3198 hell yea man! Thanks for the support!
Lady asked if I could throw her old Murray riding mower away.. So far on day 2 got it running,cutting,great, but the rear end needs work replaced. Wont go into gear possibly axel or axels.?!i?
The rear ends are easy to re build in these. I bet the gear selector is frozen
@@aaronpratt89 THANKS 👍 what ive noticed is the one side axle&rim slides in&out. The other axle locked in&spins the rear gears...?
Check the belt and pulleys under it king xenomorph
@@1993Minor It was a snap/ring fell out of the axle when I pulled on the tire..Was too ruff trying to get the tire bead on. LoL easy fix!!!iii Thanks
is it for sale ?
It is not. I actually have a few engines to build for this machine. So more content will be coming out eventually
June
I have this same mower. I'm willing to sale it if anyone is interested. It runs but has electrical issues. I'm located in Louisiana
