No other single upgrade will make your tractor more useful than the Auxiliary
Hydraulics 4X5 H3 kit. Our kit upgrades your tractor by adding a fully
integrated third function control circuit.
The Problem: Three functions, two levers.
The 415, 425, 445, and 455 John Deere Garden Tractors came from
the factory with three hydraulic functions (front right, front left, and rear
rockshaft), but only two control levers located to the right of the steering
wheel. This means two of the three functions named above are controlled by a
single lever. These two functions are the yellow/silver circuit of the SCV
(Selective Control Valve) and the rear rockshaft cylinder and therefore will
move in unison when the lever is pulled or pushed. As an attempt to improve
functionality, John Deere originally supplied an optional lockout valve to help
isolate the rear rockshaft. It is located just behind the SCV in the
Our Solution: Three functions, three levers.
The Auxiliary Hydraulics 4X5 H3 kit, when installed yields complete control
over those three functions mentioned above. The OEM levers by the steering
lever now only control the two hydraulic circuits at the SCV and the new lever
just to the right of the operator’s seat controls the rear rockshaft
NOTE: The 445 tractor has a frame mounted fuel filter which must be relocated to install this kit.
