Installation Instructions

Note: If a front–mounted implement, such as a broom or snowthrower, is used with the Groundsmaster 580–D, the Flow

Combining Kit must be installed on the machine. The Flow Combining Kit lets you direct all the oil flow to the front

implement by shutting off the flow of oil to the wing units. Complete oil flow to the front implement is required to assure

the implement gets maximum power.

Remove the Rear Panel and

the Battery

1. Park the machine on a level surface, lower all the

cutting units, shut the off and engage the parking brake

2. Open the hood and prop it up. Unlatch and remove the

left and right engine panels.

3. Remove the (6) flangehead screws securing the rear

panel to the frame (Fig. 1). Set the rear panel aside.

4. Remove the (2) flangehead screws retaining the

battery tray to the battery base (Fig. 2). Slide the

battery tray out to the side. This gives you more space

to work on the hydraulic system.

Drain the Oil from the Pump

and Remove the Elbows

1. Put an oil pan below the fixed tandem oil gear pump.

2. Disconnect the hoses from the fittings on the right

front and the rear of the pump (Fig. 3). Also,

disconnect the right front hose, which is not needed,

from the straight fitting on the PTO manifold (Fig. 3).

Install the Fittings and U–Shaped Hydraulic Tube 3. Remove the 90 degree fitting from the right front and the rear of the pump because they will not be used (Fig. 4). However, the two–piece mounting flange that held the rear fitting to the pump will be used later. The other two–piece mounting flange will not be used. 1. Install the T–fitting and the O–ring in the port at the left rear of the pump, using existing two–piece mounting flange, (4) lockwashers and capscrews (Fig. 6). Figure 4 1.

Operating Instructions 3. Loosely secure the new hydraulic tube assembly to the flow control valve (Fig. 12). The arrow on the flow control must point in the direction of the tube to the tank return. The Flow Combining Kit, by means of an in–line regulator valve between the flow combiner and the manifold, controls the flow of oil to the front and side hydraulic motors. 1.
