Abstract
A rear suspension device for a ride-on mower that includes a pivoting assembly coupled to the ride-on mower. The pivoting assembly is coupled to a torsion bar and the torsion bar is coupled to a rear portion of the ride-on mower. The coupling to the rear portion is accomplished by insertion of a portion of the torsion bar that is substantially parallel to a longitudinal axis of the ride-on mower into an aperture coupled to the rear portion. The device is callable of transferring weight from one portion of the: ride-on mower to another portion of the ride-on mower, thereby enhancing stability.
Claims9
A rear suspension device for use in a ride-on mower, comprising:
- a pivoting assembly coupled to said ride-on mower;
- a torsion bar coupled to said pivoting assembly, said torsion bar being coupled to a rear portion of said ride-on mower, said torsion bar coupling including a portion of said torsion bar substantially parallel to a longitudinal axis of said ride-on mower and said torsion bar portion being inserted into an aperture coupled to said rear portion.
A method of suspending a ride-on mower, comprising the steps of:
- coupling a pivoting rear suspension device to a torsion bar;
- inserting portions of said torsion bar that are substantially parallel to a longitudinal axis of said ride-on mower into apertures coupled to a rear portion of said ride-on mower and
- transferring weight from a portion of said ride-on mower to another portion of said ride-on mower using said torsion bar.
A method of suspending a ride-on mower, comprising the steps of:
- coupling a pivoting rear suspension device to a torsion bar;
- inserting portions of said torsion bar that are substantially parallel to a longitudinal axis of said ride-on mower into apertures coupled to a rear frame portion of said ride-on mower;
- and
- transferring weight from a portion of said ride-on mower to another portion of said ride-on mower using said torsion bar.
A method of suspending a ride-on mower for operation on an incline, comprising the steps of:
- coupling a pivoting rear suspension device to a torsion bar;
- inserting portions of said torsion bar that are substantially parallel to a longitudinal axis of said ride-on mower into apertures coupled to a rear portion said ride-on mower;
- and
- transferring weight from a first portion of said ride-on mower to a second portion of said ride-on mower located generally higher on the incline than said first portion using said torsion bar.
A suspension device for a ride-on mower, comprising:
- a pivoting rear assembly coupled to a central frame portion of said ride-on mower, said central three portion carrying an engine for powering said ride-on mower;
- a torsion bar coupled to said pivoting rear assembly;
- and
- means for coupling said torsion bar to said central frame portion of said ride-on mower and said torsion bar capable of transferring weight from a portion of said ride-on mower to another portion of said ride-on mower, said means for coupling comprising apertures coupled to said central frame portion into which are inserted portions of said torsion bar that are substantially parallel to a longitudinal axis of said ride-on mower.
