craftsman drag race mower

The front brake setup I'm going to use as a line lock/ brake setup.


Also the gas pedal I'm using. It's a push button start of of a old generator.

that switch... gas pedal? do you mean clutch? i would leave the transaxle unlocked. could get hairy at speed

Instead of me have a clutch were I push the button to disengage the clutch I'm just running the button to only engage the clutch when I push it so to me I consider that a gas pedal.

Has anyone used the centrifical belt clutch on there mower. Wich one did you use? If my electric clutch plan doesn't work I want to have a plan b.

Never used one on a mower, but plenty on go karts. For what you have in mind, you're likely going to need a race clutch like a Noram Enforcer or something.

As far as whether to lock the axle... Drag mower, right? Yup. I'd lock it. Look pretty silly trying to come off the line doin' the 1-wheel-peel!

Yea, you want that sucker to go as straight as possible.

He is most likely gonna try to use his extra jr dragster clutch

I am only running my dragster clutch if I don't build scooter stupid and if the electric clutch fails. If I build scooter stupid I need the clutch. I'm still going to try and run the electric clutch. Plus my dragster clutch is rated for at least 30hp and engages at 4000 so I would have to buy new springs for the primary and secondary.

Primary and secondary? That sounds more like a CVT than a clutch to me...

I'll upload pics when I get home it's practically the same clutch that's on a snowmobile.

Ahhh. That's a CVT.

This is the clutch that's on my car now the one I might use on the mower is the same but doesn't have an overdrive.

I fired the engine up for the first time today. All that's left before I drive it is to finish taking off all the shutoffs, bolt the steps and seat in and get a belt.

Sweet, im curious to see how that electric clutch works out for you.

I would put a 5 or 6 inch pulley on the engine and a 3 inch pulley on the rear.
