Monster Mud mower

i have one monster mower but the chain kept popping and decided to make it a road mower but i finally fixed the chain situation this weekend but i already started to make this one plus my friend has 2 so i gotta have two lol, after mudding and my friend having complications with his mower he decided to sell it to me for 25$

thats what it looked like when i first got it it has a 15.5 ohv(hate ohv's)


this is what it looked like at my house with a new hood
then here starts the mods




thats the front axle and the second to last pic shows the amount of flex it will have, i am also putting shocks onto it

6 spd tranny

hope the 6 spd lasts me because this is the one bushing on the shaft and i couldnt replace it so it wiggles around alot

the back end the pulley still needs done, fully welded and rienforcements

looking good sean

hope to have it done for this weeknd and i took my black one on the way home behind jims and didnt pop once

that's good did u test out the winch

no i didnt i didnt have enough time but im taking it in the swamp this weekend, but im ordering a shaft and bearing to raise up the pulley tonight

How'd you get that needle bearing out out of interest?
Nice to finally see a build thread of a monster mower, see how its done first hand!

sorry that picture is so bad its actualy one of the brass bushings from shaft right next to the brake disc thats why i couldnt replace it because of the disc not coming off

Chunk: You could use a square pillow block bering - only real issue id see is getting the extended input shaft straight ( no wobbling). For best results id use two berings - one near the bottom- one near the top.

when i get the parts i need i am doing basicaly your idea just its hard to explain how im doing it so when i do get the parts i will take pics and explain with them aslo chunk i already had a monster mower build but i cant remember if it was that detailed or not

Its just more for the fact the input shaft on my lawn mowing tractor has eaten into the tranny case! Can get away with fitting a new bushing or something, just not sure where to get one.

Since its done that- id match one up at the auto parts store - large enough for the input shaft, small enough for the case.

yea im not sure about that one but i would try and get one thatl work for it now

i got somemore work done

got it sitting on all fours but remember its gonna have 23's in the back and 20's in the front not no dinky tires

hole cut in the hood for the exhaust

a picture of part of the exhaust done

camo green paint i have a cool idea for the paint job

That exhaust looks good like.
Thouht for a second there that paint sprayed out a camo pattern!

Awesome, isn't the exhaust going to blow in your face though?
The camo paint will be cool.
What size angle steel did you use and what gauge?

How do you have the engine and exhaust setup up in there? Btw looks dinky with the stock tires can't wait to see the big tires!!

Looks pretty cool- imagine a set of 5 bolt rear tires off a craftsman GT on it....

1. im putting a flapper on it so it will help a little from it hitting me in the face
2. its 1/8th inch thick and how ever wide a regular craftsman front axle is
and CHUNK lol i thought it sprayed camo out awhile ago but then realized its just used for camo but heres some pics of the paint not done yet




tell me what you think and im dieing to put the bigger tires on it looks so dinky and stupid with these tires on it

looking good

LOVING THE PAINT DUDE!!!!! Totally military look. That's gotta be one of the toughest looking paintjobs I've seen.

k guys heres how im doing the rearend
first i took two old big pulleys and cut out the centers, then i slid the centers onto a 5/8 shaft and welded all around

this will act as a cupling for the input shaft and 5/8 shaft extension
then i got a jackshaft bearing or you could use a pillowblock bearing


i welded the bearing mount to a solid brace to keep the shaft from moving back and forth, this suports the shaft and will keep it from ripping out your input shaft


this is it all together you just add keys, set screws and a pulley on top with a little snap ring grove to hold it all on
and heres some pics in the light



still needs more work paint, welding, and still doesnt move

And all the stock steering linkages still work fine?

I was looking at your pics again and i spotted a yellow vintage briggs.
What model and year?
Go to the engine tech section and check out a vid of my 1949 5s if you have the time.

That beast is looking awesome, like the shaft idea, but I have 2 concerns. 1: keeping those set screws tight and 2: that mild steel rod as a shaft. I can't say for sure but I think an old axle would probly be stronger? Hope your setup works tho. You've definitely put alot of work into it and I hope it works well!
I have thought about a setup like that, but I was thinking about using a small U-joint (from a steering shaft of a car) in there somewhere to keep it turning smooth. Just throwin out some Ideas don't hate lol. I'm going to have to start building a monster as well, I will accept any and all criticism from you gratefully lol !
