FWIW 00 grease is a good alternative to gear oil. It won't seep out from around the bushings or find its way onto the brake like oil has a tendency to.

the 135's are a pretty good welder. the 70's and 80's are junk

Here's an alternative to welding...

Otherwise that welder will do fine, just make sure the weld area is clean.

I'd offer to help out with the gears, but I'm still laid-up from a wreck. If you have a small engine shop near by, stop & talk to them. Most times they strip the guts from old transaxles to scrap the casings, you can probably pick up the extra gears for cheap or free.

Eh went to the only near by places around me to see if anyone has 2 gears or a whole transaxle and nothing Neutral i might just leave if for now till i find some cause i like the fact if i did it that way with 2 extra gears i could allways change it back. Anyways im going to still run the gear oil in it i did drill and tap a brake fitting. Just going to use a 1''' or 2'' brake line with rubber hose clamped to it with a pvc valve.should work.

felt sketchy drilling a whole in my T-axle but worked out great Very Happy

Update i decided im not going to use this for mudding/offroading i got another tractor givin to me im going to use that for a woods/mud/beater rig.
Im going to use this for a little speeder lol.

Brought the mtd in got the rest of the hanging linkages off,took my clutch rods&brake rods off put new pins in it and some washers as they were sloppy as heck. Deciced not to lock trans but did permatex gasket both halfs and added gear oil in it 85w-140 .Took brake assy all off and cleaned up and anti-sized it all .One thing i dont like my engine sits to the right alot so i hope i got enough room for a front pully swap in time.
Still got alot to do
-lower seat
-bolt front axle solid
-change oil
-battery
-different air intake set up
-smaller front tires
-odds and ends-

Update: Well the mtd has been sitting out side, all the local stores have no belt size's i need in stock Mad so i got a 5'' on rear and the stock on front as the only tractor supply around has very little pulleys to pick from im going to try and take the original rear pulley and mount it on the front. If i have room. I got to make a belt tensior or something as i noticed my belt hits my shifter. Aslo i will be Up grading (i think) to another 11hp B&S but its a comercial,cast iron engine as my current one Suspect leakes oil from the seals. Well headed out now to mess with the front pulley.

Update! as in my other project murray came to an end ive decided i wont be using this for a speeder but a off road/mild mudder/ect


so this mower had the 11hp wich leaked oil from the base seal like stupid lol so that was long removed to my other tractor,well last night got the 11hp
industrial commercial wich seems to run tons better its more quite and dont leak so much oil lol. The original engine pulley for it i choped up for a diff project but i had another only prob is it sits a tad lower and the rear pulley i put on sits a tad high so the belt is off and throws it,so i got to put a spacer between the rearend and frame least 1/2 in.

what needs to be done:
Get a new belt
get some hardwear for rearend
lift rear to set pulleys even
install push button ignition
put set of rear tires on the front
bolt grill&hood on
try and mod rear tires on

well ran into pulley problems my 8'' front i made hits so im using stock for now in front still got 6'' on rear. my rear is the cast so it sits a little higher then stock wich is causing my belt to ride off the clutch pulley so i about a 1/2'' lift on rear to drop the pulley down to match up and i found out my hubs i made for the keyway axle will fit my mtd duel flat side axle,so thats bonus. Measured my belt and need a 1/2 x 79in and wouldnt u believe it tsc/true value/ace/ect dont have any in stock and online shipping is long Suspect just my luck so waiting till i get one ugh then a update and maybe a quick video description of it lol.

I used a 6" on my mod MTD and that was a tight fit - MTD's have a strange way of mounting motors to one side ( for the steering arm) - i suppose if you were handy with a welder and had extra steel , the frame could be ' bumped ' out to fit the pulley.

If you plan to going fast, i would watch that stock steering.i had the steering fail on my mtd at 6mph, and i can tell you that you dont want it happening at 6mph, let alone 20mph +. Just a heads up Wink

Update on the mtd got the rear in back in and shimed up/belt installed and a quick idle pulley, hooked up battery. Got the grill&hood mounted along with lights hooked up,the old seat was kinda riped up and staying wet so i just pulled it off like it better but its rough in the bumps and cold lol.
just running the crap outa it till spring then plan on building a double clutch set up and more front axle travel and bumpers ect. as everything now is froze lol. Well i did take it on its first romp yesterday eavning it started snowing wich gave a nice dusting,it went good got it stuck in my little swamp hole out back looked froze well wrong lmao half way across the whole thing fell through ,its not deep enough to worry abt but enough where once u get in ur not coming out so with a hand managed to get it out and back to riding.

some probs im facing is when i start sometimes in 5th it stalls the engine,is that normal?
also when full rev in 5th it seems like it reving back and forth like the govern/rev limiter is on i dnt remember my old plain 11hp doing that so im going to try and change carbs to see if that helps.
Next update ill prob do a quick video as a basic walk around lol

Small Update havnt been doing much, currently looking for a vehicle and a job. But anyways i had an old set of wheels with bad tires well my cuz has a plazma cutter cheers so i cut the center out of them for the hub cause my axles have the 2 flat spots and you cant buy them hubs around here. well i just bolted one of the centers to the wheels & tires i just got and well pic tells it all.


There Huge on it lmao, but i quickly decided im not going to use them for this tractor as fenders/foor board needs modding.
well i had an old set of goodyear sure grip tires 5-12 2ply and i was bored so i welded the centers that i cut out and put them onto these , there narrow as heck and the tractors a little tipsy but i think im going to use these for spares.
Old stock wheels cut


welded up


Narrow haha




Tomarrow i plan on building my front bumper and maybe my back bar.

Does anyone know the correct carb ajustments for 11/12 hp???
