Topic: Understanding E.C. Distributing Mower Front axle geometry

[Lambo]

10* caster, 0* toe-out. Engine is in stock location, approx. 17 " from front axle. I weigh 185lbs.

Tires:
Front = Trac-Gard 13-5.00-6 @12p.s.i  (both)           

Rear =                13-6.5-6   @15p.s.i  L    18p.s.i  R




And by the way that 17" is measured from front axle to point at which crank goes through hole in engine plate...

First thing I would do is lower left rear air pressure to get more stagger that will help it turn quite a bit. I would run 5lbs left rear. When I run a huffy I litterally had to add some weight to the left front it was simply too light with my big but on it.

[Lambo]

Ok George, thanks. How would you recommend adding the weight? , and made out of...?

I used a lead weight from old race car weights, bolted it to the frame right behind front corner of chassis. I could move seat any farther forward. I could move motor, battery everything I could mount to the front was. Been several years I think all it took was 20lbs. It made all the difference in the world. Regardless thouogh I still looked like a ape riding a golf ball.. LOL

Lol I would like to see a pic of that!

George, everything went well. I made adjustments to the air pressure and front end. Added 14lbs. of lead by melting a bunch of wheel weights and pouring into a form. When it cooled I bolted it to my E.C. front end. Runs really well. Thanks

So, after all of my adjustments, it does corner better. But now the one thing I noticed is that it pulls left down the straight-away. The more caster I give it, the more it does it. I'm not at 10* caster,  I'm at about 7 or so. Is that normal?

Lambo

[George Herrin]

Depending on left front pre-load yes its normal.

When my mower is like I like it I don't turn left, I hold right down the straight and let it turn into the corners!

[Lambo]

Now you're talking!  Thanks guys.

can any one tell me what size steel to use to make the front axle is it 2x2 square tube quater inch thick and how long is it

[Lambo]

Well- I would go a little more rectangular like 1 x 2. The length will be determined based on the finished dimension you want for the overall width with the wheels and tires on. Mine is around 18", so once i got the spindles and wheels/tires on, I'm closer to 36-38". I bought mine from EC. all ready to go-and love it.

Excel. post from George H.axel geom. To bad there is not a rough setting to start out with. Many people ask for this,myself included.I found the initial set up post after I commented. thanks George Herrin. marv

hey george on a super mod should the spindles be in the center of the axle? or below the center of the axle? mine are centered with spacers, i was having a major plowing issue this past weekend. i was running 10psi on all tires except right rear which was about 14psi. i am about 260lbs.thanks bob

[George Herrin]

Drop left front or raise right front or do both one spacer. Too much cross will make her push.
