  • Patent number: 5983737
    Abstract: A kit for converting a base transmission having a mid PTO shaft and a detachable original equipment rear cover into an optional configuration transmission having a rotatable mid PTO shaft and a rotatable rear PTO shaft that are both selectively drivable such that they can be commanded by the operator to rotate simultaneously or individually. The kit includes a conversion rear cover for replacing the original equipment rear cover, a rear PTO cover with an aperture therein mounted to the conversion rear cover, a rear PTO shaft rotatably supported in the aperture and extending into the conversion rear cover, and a three position selector assembly mounted on the conversion rear cover and the PTO rear cover. When installed on the base transmission, the selector assembly of the kit allows the operator to cause the rotation of the mid PTO shaft only, both the mid and rear PTO shafts simultaneously, or the rear PTO shaft only.

  • Patent number: 5970808
    Abstract: A vehicle transmission assembly includes a power means, a clutch connected to the power means and having an output power shaft, and a plurality of gears and substantial alignment. The gears include a first gear on the power shaft meshed with a second gear mounted on a first idler shaft. The second gear driving a third gear mounted on another idler shaft. The third gear drives a fourth gear mounted on a first PTO shaft. A second PTO shaft is operatively connected to the first shaft. A three position selector assembly on the first shaft selectively powers the PTO shafts simultaneously or individually. The method of connecting a single PTO shaft transmission assembly includes adding a second PTO shaft to said power means, and imposing a multi-position selector assembly to the gears to permit said PTO shafts to be operated together or individually.
