The 18hp Yard-Man Trailmower

This is my new build, its just going to be a fast and fun trail tractor.

specs:
12hp i/c briggs, 801? series tranny 5 speed

to do:

locking the tranny (maybe fozzy)
better steering/front axle
better tires
pulley swap something like 5 in front 4 in back
gas pedal
e-brake style seperate brake
frond and rear bumper
some storage hood rack maybe
engine swap from 10hp flathead briggs to a 12hp i/c flathead briggs w/o original carb



this is what i started with:




removed the deck and dragged it in the shop:




then i removed the engine the gas tank all the mowing related stuff and the front axle.




i stole the steering and the front axle of my parts tractor (my old jacobsen) i also removed the old crappy loose factory steering.




the factory steering had 1/2 a turn of play!





this is the new steering box i still have to reinforce it a little more but its way better than what was there.








this is where im at.

sorry for the crap quality pics my new phone died and im stuck with the one that has a burnt cam.

Neat looking machine, I like older square stuff no matter what brand. What's that plate that the engine mounts to? Is it a separate piece bolted to the frame? Never saw anything like that before. Any thought about making some sort of front bumper?

Looks cool, I like the color scheme. Whatcha thinkin for tires?

Lol I can't see the pics, but it sounds good!

i like the square body stuff too.

the engine mounts on a plates that mounts to the chassis trough plastic\rubber bushings, its suposed to reduce the vibration i guess but it doesnt really do much.

i dont really know how my bumper is gonna be, i know i want some lights some tow points. also the front axle is going to be welded in solid.

in the 20 inch region but i dont know, something cheap or what i can find for a reasonable amount on my local classifieds haha but i really need some front tires.


oh i forgot to say its going to be ungoverned, i dont have the stock carb.

i finished mounting the new front axle, i made a frame to mount the axle because the stock sheetmetal one wasnt strong enought.

ok it may be overkill but i also need weight in the front of the tractor so it helped for that too.


test fit





axle frame
[





its gonna hold haha

i need to get new bushings for my front axle, for now i have steel ones but i need to change them.

next plan is hooking the steering and mount the hood back on.

got some more work done today


got the engine mounted, and got some ideas on a pull start



mounted a fuel tank from one of my 8hp briggs


and changed the clutch spring for a way stronger one.




i also got the choke hoocked up

tommorow ill make a gas pedal and redo the wiring, ill also mount the battery.

today i made a gas pedal
i made some battery mounts
and i did the wiring ill post pics tomorrow.

i have a dual battery setup it cranks real nice.

heres the custom heavy duty gas pedal i made its nice.

drove it for the first time with the new axle and the new engine today it works great. next is a pulley swap finishing the front bumper and getting some lighting going.

yeasterday i got the rear pulley swap and belt guard done. the rear has a 6inch now







today i started building a nice hand brake. i used some old mowing deck hardware like i did for my gas pedal.
the hand brake is going to be spring loaded and have a lock to use as a parking brake.

this is how i made the lever and the pivot thing.






then i started to make the simple linkage





after that i pushed the tractor on its side and f****** WATER started dripping out of the tranny. guess ill have to tear that appart. oh well i have to lock it anyways.

puddle of water from the tranny...


so heres the handbrake its almost done i just have to put a return spring and a parking lock mecanism.

Looks good. I like the placement.

Nice build man! It looks cool with dual sticks like that, kinda like an old tractor.

Looking good! It looks like it has a Hi-Low tranny Is the brake lever pivot-y thing just like the way the shifter is done?

the shifter is stock, but its the same way i did the gas pedal.

Yeah, but I mean like the shifter has that pivot-y thing but it's connected to the trans. I gotta do a brake like that on my tractor. I also like the belt guard

i think it has the same transaxle that is in my king. a peerless 801. mine was full of water too, because some knucklehead tried to change a tire and ended up hammering the axle out. good transaxles. they are a nice medium between the really heavy duty 820s and the lighter duty 900 series.

yeah they seem to be pretty solid. and im gonna be putting a solid axle and converting it to oil lube soon.

Nice! Are you using an arc/stick welder?

no its just a normal flux cored welder 80a i think.

its the higher end model that is both mig and flux core but i cant find gas anywhere...

today i did the pulley swap !


ITS AWESOME... i love it haha. its my first tractor thats works great, everything i built worked how i wanted it to and thats just awesome.


now its fast and idk if its the carb but it runs nice, it does smoke quite a bit when i punch the throttle (too much to be normal) rings maybe ? idk

i got my 6in pulley today at my local bearing supplier for 34$

i also had to add an idler pulley to make the thing work withoud havint to buy another belt. that worked great too.

the brakes work really good too.

ill post pics tommorow.

Cool! Is it black smoke? If so it could be running just a wee bit rich.

could that be why it burns alot of gas ? its darkblueish i guess haha not quite black

how do you adjust the carb ? its a carb from a 400cc 11hp b&s

Well for that style carb the high throttle mixture screw is on the bottom of the float bowl. If is running a wee bit rich you wanna turn it in like youre tightening it. Just a little bit though, too much and it will be running too lean. Also when you adjust the high idle screw you should rev the engine a few times to see if it will still rev up smoothly, and run it at WOT to see if it is misfiring or having trouble running. Just a slight adjustment should necessary to fix the smoke problem. That is if its fuel smoke.
