35speed beast MTD/Toro

Hey guys I'm working on a 35 speed MTD lawn tractor and I just wanted to throw it out there so tell me what you guys what you think.

Sorry if I don't get pics up cause I'm new to the fourm

Sounds cool iv never heard of a 35 speed lawn mower.

35 Mph? or 35 gears?

I'm going to take a shot in the dark and say MPH.

It's going to have 35 speeds. It will use a 7 spd vari drive from a mtd and a 5 spd pearless so it'll have 35 gears

Check out the thread that Jamus put up ''Montgomery wards trail tractor now murray wide body Lt'' on the second page he mentioned it.

Oh ok.

thinking of trying same thing but I have a 6 speed trans

Awesome then it'll be a 42 speed tractor!!

Oh... Well, that's surprising.

So a couple minutes ago I was trying to get the mtd running n driving to see if everything works before I put TOO much time into this build and I put it in gear so the input shaft on the trans-axle wouldn't turn when I put the pulley on but it turned any in forward and reverse so i dunno whats wrong but thank goodness I wasn't planning on using that tranny because I do not have another that works.

The vari drive is really a CVT tranny, with infinte ratios between the top ratio and bottom ratio. They just called it a 7 speed, because they had 7 postions.

So you have a zillion ratio tranny....

COOL I never really thought of it that way, so does that mean that i can make it have more speeds?

You could make it have any ratio, but only between the top and bottom ratio. So instead of 7 postions, you could have 3, or 12 postions. All in how you set up the shifter. It won't go any faster or slower than before.

Ok that makes sense now!!

I have a question does anyone know how fast stock mtd vari drives go roughly??

I dont own a vadi drive but i think they go 9-10Mph.

Yea 10mph or so max

Thanks for the speed info but what pulley ratio should I put on when I get the 5 spd in (hopefully this weekend) I'm thinking 1:1 but not sure if that'll mess up the double pulley drive. Tell me what you guys think.

1:1 ratio will work good

Ok I just wasn't sure if it'd work with vari drive so THX!!!

Like I said hopefully this weekend I will get the mst-205 peerless out of my toro (or mst-206 out of another dynamark/murray) and swap it with the single speed in the mtd I will also try to get the 20hp briggs out of my parts tractor to replace the blown 18 in the mtd now. WISH ME LUCK!!

I am sorry for the lack of work....with school, boy scouts, and everything else I do I didn't have much time to work on this .....BUT I now have made good progress this morning. I have everything ready all I need to do is get a pulley preferably 5'' and it needs to be compatible for a 5/8'' belt, I dont think tsc is open today but if it is I will get a pulley and get everything lined up then I might put my trans-axle in depending on if we have enough time.


Hopefully i will get pics in tonight or monday night.

You're 13, and doing this??? Right on! Kudos to you- I absolutely love seeing young'uns learning how to wrench- you're a dying breed. Seems most kids are just too wired in to the technocrap these days.
