An equalizer bar for a tracked vehicle is connected to the track roller frames via an arrangement comprising a pin which is swivel ably mounted to the equalizer bar and held rigidly by the track roller frame. The pin is positively held by the track roller frame, for example by channels in which the pin sits such that the side load is at least partially absorbed by the channel walls rather than the fasteners. The fasteners are located such that they experience minimal side load and aid a positive location of the pin in the channels.

What is claimed is: 1. An arrangement for connecting a track roller frame to an equalizer bar of a machine, said arrangement comprising: a pin connected with said equalizer bar and projecting therefrom, said pin having a first surface portion with a first pin passage therethrough, said track roller frame having a first surface portion corresponding to said first surface portion of said pin, said first surface portion of said track roller frame having a first track roller frame passage extending therethrough, wherein said pin has a longitudinal axis and said pin is connected with said equalizer bar such that said longitudinal axis has three rotational degrees of freedom relative to said equalizer bar; a first fastener extending through both said first track roller frame passage and said first pin passage in said first surface portions of said pin and said track roller frame; and a spherical bearing providing said longitudinal axis with said three rotational degrees of freedom relative to said equalizer bar. 2. An arrangement according to claim 1, wherein said first surface portion of said track roller frame is part of a recess adapted to receive said pin such that at least a portion of said pin sits in said recess. 3. An arrangement according to claim 1, wherein said first surface portion of said track roller frame is generally concave. 4. An arrangement according to claim 1, wherein said pin has a tight fit in said recess such that lateral movement of said pin in said recess is prevented. 5. An arrangement according to claim 1, wherein said spherical bearing is an elastomeric bearing. 6. An arrangement according to claim 1, wherein said pin includes a second surface portion with a second pin passage therethrough, said track roller frame including a second surface portion corresponding to said second surface portion of said pin, said second surface portion of said track roller frame having a second track roller frame passage extending therethrough, and a second fastener extending through said second pin passage and said second track roller frame passage passages in said second surface portion of said pin and said second surface portion of said track roller frame. 7. An arrangement according to claim 1 wherein said first surface portion of said track roller frame is located on a bracket, which is cantilevered from, said track roller frame. 8. A method of connecting a track roller frame to an equalizer bar of a machine, said method comprising the steps of: providing said equalizer bar with a projecting pin having a longitudinal axis and a spherical bearing, such that the spherical bearing provides said longitudinal axis with three rotational degrees of freedom relative to said equalizer bar; positioning at least a portion of said pin in a recess located on said track roller frame; fastening said pin to said track roller frame by extending a fastener through said pin into a portion of said track roller frame. 9. A machine comprising: a main frame; an equalizer bar pivotably mounted to the main frame; a track roller frame; and an arrangement connecting the track roller frame to the equalizer bar, the arrangement including: a pin connected with said equalizer bar and projecting therefrom, said pin having a first surface portion with a first pin passage therethrough, said track roller frame having a first surface portion corresponding to said first surface portion of said pin, said first surface portion of said track roller frame having a first track roller frame passage extending therethrough, wherein said pin has a longitudinal axis and said pin is connected with said equalizer bar such that said longitudinal axis has three rotational degrees of freedom relative to said equalizer bar; a first fastener extending through both said first track roller frame passage and said first pin passage in said first surface portions of said pin and said track roller frame; and an elastomeric bearing providing said longitudinal axis with said three rotational degrees of freedom relative to said equalizer bar. 10. The machine according to claim 9, wherein said first surface portion of said track roller frame is part of a recess adapted to receive said pin such that at least a portion of said pin sits in said recess. 11. The machine according to claim 9, wherein said first surface portion of said track roller frame is generally concave. 12. The machine according to claim 9, wherein said pin has a tight fit in said recess such that lateral movement of said pin in said recess is prevented. 13. The machine according to claim 9, wherein said pin includes a second surface portion with a second pin passage therethrough, said track roller frame including a second surface portion corresponding to said second surface portion of said pin, said second surface portion of said track roller frame having a second track roller frame passage extending therethrough, and a second fastener extending through said second pin passage and said second track roller frame passage passages in said second surface portion of said pin and said second surface portion of said track roller frame. 14. The machine according to claim 9 wherein said first surface portion of said track roller frame is located on a bracket, which is cantilevered from, said track roller frame. 15. A machine having an arrangement connecting a track roller frame to an equalizer bar of a machine, the machine comprising: a pin connected with said equalizer bar and projecting therefrom, said pin having a first surface portion with a first pin passage therethrough and a second surface portion with a second pin passage therethrough, said track roller frame having a first surface portion corresponding to said first surface portion of said pin, said first surface portion of said track roller frame having a first track roller frame passage extending therethrough, said track roller frame including a second surface portion corresponding to said second surface portion of said pin, said second surface portion of said track roller frame having a second track roller frame passage extending therethrough, wherein said pin has a longitudinal axis and said pin is connected with said equalizer bar such that said longitudinal axis has three rotational degrees of freedom relative to said equalizer bar; a first fastener extending through both said first track roller frame passage and said first pin passage in said first surface portions of said pin and said track roller frame; and a second fastener extending through said second pin passage and said second track roller frame passage passages in said second surface portion of said pin and said second surface portion of said track roller frame. 16. The machine according to claim 15, wherein said first surface portion of said track roller frame is part of a recess adapted to receive said pin such that at least a portion of said pin sits in said recess. 17. The machine according to claim 15, wherein said pin has a longitudinal axis and said pin is connected with said equalizer bar such that said longitudinal axis has three rotational degrees of freedom relative to said equalizer bar, wherein a spherical bearing provides said longitudinal axis with said three rotational degrees of freedom relative to said equalizer bar. 18. The machine according to claim 15, wherein said pin has a longitudinal axis and said pin is connected with said equalizer bar such that said longitudinal axis has three rotational degrees of freedom relative to said equalizer bar, wherein an elastomeric bearing provides said longitudinal axis with said three rotational degrees of freedom relative to said equalizer bar.
