Okay today while getting some pulleys and other misc. stuff to finish the whole mower on friday I had a sudden brainstorm. I was thinking about watching all those car shows on that spike channel and where they had been using alot of 4 link suspension. So.... I said why not give this a wurl on the next mower and a shot by the forum and see what others think. I was thinking take some metal and make mounts for 4 tubular supports.  And then after making the mounts for the links I thought you then can take some springs from a go-kart. http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_22932_22932and mount these to hole the tranny. Hope you guys can follow this alright. Or maybe this is better.  Posted on: August 12, 2007, 01:40:53 PM

The springs can be adjusted from hard to soft. Mostly you can leave them at very hard so they dont move.

This setup will require a live axle and seperate trans with a chain and tensioner like a dirtbike or racing type atv.

With a live axle you would only need 1 spring on each side to make it work, its basically identical setup to a chain driven ATV except they have one center spring.

A rear suspension would be easy on a rear engine mower, even with a transaxle. You could hinge the frame right in front of the motor. Use a cable pull for the clutch.

The idea of the setup would work good, but you'd have to run a live axle and transmission. A transaxle would be way too much of a pain to have the belt constantly aligned, if you weren't throwing belts all the time (which you would), you'd be burning them up from over-stressing them. I have a similar setup designed for my golf cart, which is getting a 700, live axle, and more than likely an opposed (or intek if I can find one cheap).

Just because you move up in a class doesn't mean that you'll "loose" the "race", it just means that you're building a better, more capable machine. |

I see alot of unfinished races in that designs future, unless you add a crap load of guide pins (like on the deck) I say convert to solid axle, as it might cost a little more, wait till you pop the transaxle you got.
if you could move the transaxle forward, and use the shafts as the pivot, you could make a single swingarm pretty easy, I'm working on that for ATGC, except I'm using a jackshaft for the swingarm pivot. I dont know that you'll like the outcome after all the work is done though.

you can use a transaxle you just need to use the right one. the 2300 for example has a horizontal input
