The 18hp Yard-Man Trailmower

That steering arm looks good! Shouldn't break any time soon. Looks like that old steering wheel is pretty tweaked hahaha.

Nice build man I just started a similar build, it has an 18hp opposed as well. Do you have a video of that stack? That thing is sick! haha I was thinking dual stacks but I might have to steal your idea on that single it looks very clean.

the stack was just a mock up, the thing isn actually done, i have to weld up the pipes i have everything ready.. i just have to weld it up.. ill post a vid when i get it done !

Oh haha I gotcha.

Today i made a gas tank holder.. so now it not only attached to the dash with zipties...

Looks pretty good! Ya gonna put some rubber or something between the tank and the bracket? Dont want the metal on metal to cause a hole in the tank or anything haha.

So i was coming back from my little test drive and, yeah, the axle just sheared right after the bearing..

im going to doc lock the mst 205 and make axle supports next


goign to try to get the mst locked tommorow, and maybe start the axle supports but now im dreaming..

I really dig that exhaust man!

Now how the heck did you do that??

yeah i REALLY like the exhaust, the tone is great ! and i looks great too !

and i think the main thing is when i was doing donust last week and the right rear tire hooked and threw me off it, it probably cracked or bent the axle some, and the riding after that finished it..

oh well i needed to swap the mst anyways..

Sux about your trans, but that exhaust looks great!

Exhaust looks good man! Kind of a bugger about your axle shaft, seems like you have a bit of bad luck when it comes to bending and breaking them haha.

I like the exhaust! Pity about the axle shaft, but a good excuse to Doc Lock it!

yeah i love the new exhaust, but im kinda getting used to breaking my transaxle.. oh well. lets hope that the supports will fix my problem..

However, i was able to get some work done today !
i cracked open the mst and inspected everything in there, looks great, cleaned out the case and startet the doc locker 2.0 !


this is where im at.


i was going for the weldless doc locker 2.0 but i changed my mind.
im going to get a slitghly smaller hub and make some kind of doc locker 1.5, use the hub and weld parts of the original crosspin. i just like it better that way.
Also getting a 5 inch pulley for the mst more speeeds !!
still trying to get new rear tires for cheap haha

well i only got time to get the parts today.

got a new pulley 5inch to remplace the 6 inch on the transaxle. still using the 8 inch in front.
got a lock collar to get the doc locker done with the new hub
and i got some nice pillowblock bearings to support the axle ! with the supports ill be able to space the tires out a little more than stock for more stability, and better donuts



hoping to get this thing soon ! should be sweet with the new pulley swap and the muffler, and possibly new tires !!

Man, you know how to clean a trans case! Looking good!

soo i rushed on the yard man to get uit out of the shop, need the space for the terrajet lol ! axle supports will come later.

reinstalled the hood finally. had to cut it up a little to fit around the engine lol it looks great with the new exhaust, sound excellent also !



finished the doc lockes 1.5 mst205 !

Nice! Good to see 'er with the hood on again, looks like it fits pretty good now.

Looking good, does the top half fit ok with the bearings in there? Mine didn't seem completely cut out on the top side. Bottom was good.

seems totally fine for me !

Good deal!

last weekend i properly rewired the thing with crimp connectors and all, got the boost system thingy nicely installed, rebuilt the starter with used brushed, again, and did a headlight mod.

heres some pics.

a couple months ago i bought a pack of cheap 1156 led tailight bulbs, 10 for 2$. but they are only rated to about 1.5W each, so about equivalent to a 15W incandescent. factory bulbs are 22W. so a single bulb per headlight wasnt enought, i just drilled a one inch hole in the enclosure and fitted some spare sockets i got off another tractor. worked great. now i have the equivalent of 60W of lighting but it only uses 6 watts, with the dual battery setup it means i could run them for days !

Now i have leds all around !

wiring all cleaned up and ziptied haha
i also had to instal a choke cable, i could get it to start without a little choke, its getting cold here.. i still have to get a longer cable and install it in the dash..

used a 50A anderson connector.

ill make a couple of special cables, all my tractors have this connector hooked up to their batteries so i have a conveniant way to boost them or other tractors.. i can also use this connector to charge the batteries or extend the capacity of them by storing another one in the bumper and connecting it with the main ones. (now i always carry a small battery with the adaptor to boost the tractor if i drain the batteries on the trail)



i also ran a wire for the low oil pressure switch, ill get a red indicator led to install on the dash to show low oil pressure.. gettin fancy

axle supports are coming.

to do:
-wire up the engine, dual diode setup DONE but redoing it with proper connectors
-make up an exhaust, 2 to 1, with atv mufller
-battery boost system, anderson plug ?
-front bumper W front towhooks
-make the hood fit around the engine..
-headlights, nilights dual flood..
-add a 3rd battery ?
-buy and mount new rear tires
-rear mud flaps
-front fendersnah
-swap an even bigger engine pulley or smaller rear ?
-belly pan, keep the sticks out of my belt..
-Swap in MST205 after i doc lock it.
-voltage regulator ? building a small alternator out of a small electric motor !?
-steering stops
-axle supports

Looking good! A low oil pressure light would be pretty cool.


This guy bragging about his pressure lube oppy....
