Abstract
A self propelled, steerable, vertically adjustable, hydraulicly driven, ganged mowing machine for trimming nursery products. The machine generally includes a horizontal platform that supports a staggered array of mower decks. Each mower deck is driven by a hydraulic motor operatively connected to a mower blade for trimming the nursery products. The platform is slideably connected to right and left vertically stationary frames such that the platform is vertically adjustable with respect to the ground, via a hydraulic cylinder interconnecting the platform and each frame. Each vertical frame includes an independently controllable hydraulically driven traction drive motor operably connected to a drive wheel for propelling the machine. The mowing machine also includes a prime mover. The prime mover drives a number of hydraulic pumps. At least one of the hydraulic pumps drives the hydraulic motors which drive the mower blades. At least one pump drives the traction motors mounted on the vertical frames, and at least one pump drives the hydraulic cylinders for vertically adjusting the platform. The mowing machine also includes a seat for a driver, and controls for operating the gas engine, traction motors, and for engaging the mowers. The mowing machine is self-braking.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
