Hi Guillaume, numbers are down from last year a bit but this year we where averaging 8-10 machines every Tuesday night.

Here is the track contact info:

Thanks, it was a YARDWORKS mower (probably an off brand of an other manufacturer)

Hello fellow racers, just wanted to introduce myself on the forum. I'm located in eastern Ontario Can. and race weekly at the Cornwall raceway park dirt oval. I have been racing 2 stroke Rotax karts for a few years and just got into modified tractor racing towards the end of the race season(four races so far) and I can say without a doubt that I have found my new calling with tractor racing....this is such a blast!

So here is my machine, now that the racing season is completed, I will be doing a complete teardown/rebuild over the winter to get ready for the 2014 racing season. The tractor is powered by a single cyl Briggs flathead on methanol, a pearless 800 differential.

Rob.

Thanks for the reply Cody,

I agree on leaving the governor while using the stock engine internals, at the very least I would use a flywheel scatter shield which I will likely do anyway. I wish that I could use a live kart style axle but our track rules requires the use of a tractor transaxle and centrifugal clutch/belt drive line so I'm on the hunt for a 820 Peerless to build up. The 2.5' ground clearance is just the track rule min spec dimension but as you mentioned, I will be around the 4'' mark at the bottom of the front axle.

I'd still like to get some of you guys thoughts on rotating the engine 90 deg counter clock wise 8)

Thanks again for your input!

These are our track rules:

Hi,

I'll start off by giving you a quick overview of what i'm starting with, what ideas I have for the build, what class it will be raced in and hopefully I can get some advice from some of you experienced racers to get me going in the right mowrection!

So I just picked up Craftsman tractor that I will be racing in a modified class that uses the model 28 12 hp Briggs -Stratton flat head motor in basically stock form other than a .020' over piston, cleaning up the carb inlet/intake, increase jet size if we run methanol, after market air filter/exhaust and removing the governor mechanism is optional,  we must use a centrifugal clutch and drive belt. We can lower the chassis to a 2.5" min. ground clearance, 1.5" chassis offset, the usual front axle/steering/rear brake, frt/rear bumpers/side nerf bars upgrades.

Things I like to do(please advise me if I'm wrong)
-Flip the differential to lower the chassis and keep the frame, drive belt and engine level to the ground.
-Offset the chassis to the left 1.5"
-I would like to rotate the engine 90 deg counter clock wise(looking from the top) and possibly offset the engine to the left side. I've seen this done before in one of the build threads, I think that it would make sense to rotate the engine 90 deg counter clock wise to keep the oil from sloshing forward into the the bottom of the piston when braking and in left turns. Having the head hanging out the left side would move some weight from the front of the tractor and place it farther back and to the left(free ballast and better chassis weight balance) Again, I could be way off on this so chime in if that's the case! ;)
-I'm undecided on whether to use a steering wheel mounted throttle lever/foot brake pedal setup or steering wheel with both foot brake and gas pedals or an ATV type handle bars with brake and gas hand levers. The racing series allows both types of steering setups.


The tractor came with a FOOTE 3865 differential, is this unit usable for racing or is it more useful as a boat anchor.

So here we go, I'll start of with a few "before' pics ...it's not purdy but the frame/body work is clean and solid, I kind of like the oldschool square look of the hood but we'll see maybe I'll go with one of the modern round hoods..... I will have many more question for you guys and gals so please be patient with me, I'm here to learn :)
