It's a 5 speed. Peerles i think.

Looking good so far, can't wait to see your progress

From the pic I'd guess a Peerless 900, 920 or 930
I've got a locked 900 in my tractor; so far it's held up fine

im hoping me weld holds, im not that good with electrodes.
getting a little flux core welder soon.

some updates:

welded the front end in locked.




flipping front pulley:

cut the long end off and welded it on to the other side.




my welder, grinder and welding helmet:

Good progress!
I did not weld mine, I used 2 extra spider gears.

Wow, those are nice clean welds, I cant get welds to look that good with my arc welder. You must of had way more practice than I have. Keep up the great work .

That is alot less cleaning or having the risk of the weld breaking.
I dont have extra spider gears so i just like welding them.

Thanks. I make nicer welds using mig. Getting a little mig soon.
I do practise quite alot, but im still not happy with my arc welds.

What do you guys think about an extra break that rubs on the tires?

updates:

have been working on the briggs twin today:




one of the intake manefolt ears broke off:


does anybody have an idea how to fix this?
is it possible to weld it or something?

muffler off:


my brother talkt me into doing stacks on the mower.


im trying to figur out what size rear pulley i should get to get a top speed of about 30/35 mph? anybody have an idea?

update:

fixed the intake with some exhaust sealer.



straight pipes(not done yet)




also sealed all the welds with the gungum exhaust sealer.

JB weld wouldve worked for the intake crack - ive used it to repair some small holes on a couple tractor decks as well.

Id probably go a lil longer on those exhaust tubes- i ran shorty pipes on my mod murray and the thing backfired /popped like crazy - it can eventually burn a valve - briggs motors like a little back pressure.

Im hoping this will hold up, but if it doesn't i will JB weld it.

The straght pipes are going to be a bit longer, problably exiting underneath the runningboards.

Cool - when i get around to building my rat rod wheelhorse i plan on putting pipes like this on it, cept a lil bit more under the foot rests :


( No this isnt my tractor)

Hey awesome tractor man! I just started mine today and have some of the things your doing and doing them on mine but I dont think ill put stacks on mine.
Awesome work, keep it up!

That is going to look slick, what engine is the rat rod getting?

Thanks alot.
Get some pics of your mower and post them on the forum. I would love to see it.
Im not going with stacks anymore, because of the exhaust fumes getting in my face.

That was a pic i found on a racing tractor website - altho i have a couple stock tractors of the same model.

My rat rod is going to have a 03 bolens chassis ( MTD) , and original unpainted rusty sheetmetal off my 69 raider 10 wheelhorse - itll be lowered, 8" golf kart rims all around, straight rear axle, and a 18HP twin opposed briggs - debating on wether to use a peerless 700 or right angle gear box with go kart clutch.

That bolens frame is going to be very strong and the wheelhorse sheetmetal is going to look sweet.
The 18 horse briggs are great engines. Are you going to do any mods to the engine?
I have a peerles 700 laying around, pretty strong transmissions. Ive seen people put little needle bearings in them to replace the bushings.
Its nice to be able to shift, and having lots of torque.
Right angle gearbox is easy to install and setup. But its more exspensive.

I have one thats stock that was on a mod murray, i ran it with the governer and it was scarey fast - i have another briggs 18HP that i was trying to set up dual carbs on to see if it even ran ( was missing carb and intake) , i bot a couple street scooter carbs at a flea market - i was thinking of hooking one up with a custom intake possibly. Its still up in the air what ill use on it.


I already have both - the 700 peerless and the RAGB - the 1:1 RAGB i bot off ebay for $25 because a pulley is stuck on it ( ill have to cut if off) .

Itll be a bit before i get working on it - i have a few other projects and stock mowers to work on first.

Dont think those scooter carbs will do. Ive seen people put snowmobile carbs on twins. Works great and gives them lots of power.

I bought my 700 togheter with a little RER rear axle with ballbearings for 50 bucks.
My toro groundmaster has a RAGB on the rotted out mowing deck. Im hoping i can save the deck, but if i cant save the deck i wil use the RAGB for a project or something.

When you do start to build yout ratrod mower, be sure to put it up on the forum.
