    Zero turn radius without using swivel casters

    I tried 8" omni wheels last week and they failed miserably in grass due to the rollers being too small, so I'll be returning them. That is why I proposed the spherical (anti-scalp) shaped wheel. Using casters is a last resort as I want to take up less space and a 6-7" caster would require a...

    Zero turn radius without using swivel casters

    Same principle as these mowers: (which is classified as zero turn by the way) Two fixed rear wheels that can move independently from each other (like a push mower) and two front wheels that can either swivel (like the below picture) or a spherical wheel like I proposed which would use sliding...

    Zero turn radius without using swivel casters

    I know that. I thought my question was pretty clear. I'm wanting to avoid pushing down on the handle bar and simply rotate the mower instead, hence my post. What I'm more insterested in is the mechanics behind this to see if this is a solid idea. Also, it was my intention of only doing the front...

    Zero turn radius without using swivel casters

    Thank you, here is my mower: (standard 20" cut) Also I said I don't want to use casters in my original post. The wheel in my first post would bolt right up to the stock axles. My question is, would this style of wheel (contoured edges) simulate zero turning due to the smooth plastic and...

    Zero turn radius without using swivel casters

    I'm not sure if this question fits here, but I've had trouble finding a good simple physics forum, so I signed up here :) I'm trying to think if the below wheel (image below) could allow for my push mower to have a zero or near zero turn radius. The edges of the wheel contour up (from the...
