Tag axle attachment for an off road agricultural applicator vehicle
First Claim
1. A tag axle for use with an agricultural vehicle having a chassis with a front, a rear, and two spaced apart side rails, a front axle attached to said chassis having one or more wheels, a rear axle attached to the chassis having at least a first wheel and a second wheel, wherein the first and second wheels are located on distal sides of the rear axle, the tag axle comprising:
- an axle assembly having an axle and at least one wheel;
a mounting bracket having a first end and a second end, the first end being adapted to couple to the chassis of the agricultural vehicle;
a swing arm assembly having a third end and a fourth end, the third end of the swing arm assembly being pivotally attached to the mounting bracket proximate to the second end of the mounting bracket and the fourth end of the swing arm assembly being pivotally connected to the axle assembly; and
a telescoping device having a fifth end and a sixth end, the fifth end being pivotally connected to first end of the mounting bracket and the sixth end being pivotally connected to the axle, said telescoping device actuating the raising and lowering of the axle assembly wherein the agricultural vehicle has a single front centrally aligned wheel, and wherein a wheel of the axle assembly is aligned with the front wheel of the agricultural vehicle.

Abstract
The present invention provides a tag axle attachment for an off-road agricultural vehicle. The tag axle attachment allows agricultural vehicles to meet roadway weight restrictions imposed by the federal and state governments while also allowing the vehicle to perform optimally in the field. The tag axle is assembled such that it can be hydraulically lowered into a deployed position when the agricultural vehicle is on the roadway and hydraulically raised into a stowed position when the agricultural vehicle is in the field. The tag axle assembly is mounted to the chassis rails of an agricultural vehicle and positioned to fit between the chassis rails when stowed and minimizes the load per axle of the vehicle when deployed.
