Quick Attach Front Frame

1. Park machine on a level surface with the cutting deck in the fully raised position. Shut off the engine, engage the parking brake and remove the key.

   Note: When the cutting deck is in the raised position, the pull link torsion spring tension is reduced making it much easier to disconnect the pull links from the machine.

2. Disconnect the pull link from each side of the machine as follows:

   Caution

   Be careful when disconnecting the pull links. The pull link torsion springs may cause some rotation of pull links during the removal process.

   • Remove the shoulder screw that secures the retainer pin to the carrier frame (Figure 1).

     2. Retainer pin
     3. Ring pins and clevis pins

   • Carefully slide the retainer pin from carrier frame and the pull link.

3. Note the location of the height-of-cut pin in the height-of-cut bracket for re-assembly purposes (Figure 2). Remove the height-of-cut pin from the height-of-cut bracket.

4. Position suitable furniture dollies under the cutting deck.

5. Start the engine and fully lower the cutting deck onto the furniture dollies. Shut off the engine and remove the key from the ignition switch.

   Warning

   Do not start the engine and engage the PTO switch when the PTO shaft is disconnected from the cutting deck. If the engine is started and the PTO shaft is allowed to rotate, serious personal injury and machine damage could result. Remove the PTO fuse from fuse block to prevent unintentional engagement of the PTO clutch.

6. Lift the floor plate, exposing the top of the cutting deck.

7. Disconnect the end yoke of the PTO shaft from cutting deck gearbox shaft as follows.

   • Remove the roll pin from the end yoke and the gearbox shaft (Figure 3). Retain the roll pin for re-use.

     2. PTO shaft end yoke

   • Loosen the 2 capscrews and locknuts (Figure 3).

   • Slide the driveshaft end yoke from gearbox shaft and tie them up to the frame for support.

8. Remove the 4 ring pins and clevis pins that secure the deck lift chains to the adjustment clevises on the cutting deck (Figure 1).

9. Roll the cutting deck away from the machine.

Parts needed for this procedure:

1. Loosely install the shorter hydraulic tube to the straight fitting on the valve (Figure 4).

2. Loosely install the longer hydraulic tube to the straight fitting on the manifold (Figure 4).

6. On the rear of the attachment, loosely install each side to the frame channels with 2 screws (1/2 x 1-1/4 inches) and flange nuts (1/2 inch) as shown inFigure 6.

7. Using the remaining 4 mounting holes, secure the attachment to the frame cross plate with screws (1/2 x 4-1/2 inches), spacers, and flange nuts (1/2 inch) as shown inFigure 6). Position the spacers between the screw head and the cross plate.

8. Tighten the fasteners to 91 to 113 N⋅m (67 to 83 ft-lb).

9. Secure the top link assembly to the axle support with a screw (1/2 x 3-1/4 inches), 2 support washers, spacer, and a locknut (1/2 inch) as shown in Figure 5 and Figure 6.

   Note: The washers are to be positioned on the outside of the ears on the axle support. Figure 7).

Parts needed for this procedure:

1. Place a drain pan under the caps on the hydraulic tubes (Figure 8).

2. Remove the caps from the hydraulic tubes on the machine (Figure 8). Remove the caps one at a time as installing the tubes to prevent excess hydraulic fluid loss.

   

   Figure 8

   1. Hydraulic tube caps

3. Connect the rear end of the shorter hydraulic tube to the tube on the machine (Figure 9).

4. Connect the rear end of the longer hydraulic tube to the tube on the machine (Figure 9).

5. Tighten connections.

6. Loosely secure the shorter hydraulic tube to the adjacent tube, on the machine, with the smaller tube clamp, plate, carriage screw, and flange nut, as shown in Figure 9.

7. Loosely secure the longer hydraulic tube to the adjacent tube, on the machine, with the larger tube clamp, plate, carriage screw, and flange nut, as shown in Figure 9.

8. Tighten the carriage screws and nuts.

1. While aligning the driveshaft mounting holes with the jack shaft hole, slide the driveshaft onto the attachment jack shaft (Figure 10).

2. Secure the driveshaft to the jack shaft with the roll pin previously removed.

3. Tighten the 2 driveshaft cap screws and locknuts.

Parts needed for this procedure:

1. Use a knife to cut out the provided decal.

2. Remove the knock-out by pressing on it from inside the console.

3. Install the decal between the switch holes.

   2. Decal

4. Install the switches by pressing them into the holes.

5. Connect the wire harness to the switches.

To operate the front attachment, use the rocker switches as indicated in Figure 13.

Figure 13

1. Front attach raise and hold
2. Tap to float front attach down. Hold to power down.
3. Swing front attachment right
4. Swing front attachment left

Important: Do not hold down the power down switch once the attachment has been fully lowered; this can cause significant hydraulic system damage and result in front attachment damage.

Read the Operator's Manual supplied with the attachment before operating.

Ensure that the hydraulic quick couplers are free of any contaminants before connecting.

Keep the output shaft oiled to prevent rust.

Do not operate the PTO with the attachment in the raised position. Noise from the PTO drive line will be evident.

Install the attachment as follows:

• Remove any attachment from the machine. Follow attachment supplier's recommendation for safe blocking and storage.

• Drive the machine into position behind the attachment adapter. Raise the machine adapter into the attachment adapter.

• Secure the adapters together with the attachment pin and hairpin cotter as shown in Figure 14. For more abusive loading a nut and bolt may be substituted.

Removing the deck

1. On a flat level surface raise deck to highest position.

2. Place 2 furniture dollies under each end of the deck and lower it so it rests on the dollies.

3. Remove the bolts (5/16 inch) and remove the pins from the drag-links on each side of the deck.

4. Remove the four retainer clips and clevis pins from the chains suspending the deck.

5. Remove the roll pin and loosen the bolts securing the driveshaft to the deck.

6. Slide the driveshaft off of the deck gearbox and secure it to the frame of the machine with a bungie cord or strap.

7. The deck can now be rolled out from under the machine.

8. If preparing the machine for winter work, it would be advisable to remove the deck hanging chains.

Attaching the deck

1. If the deck chains were removed from the lift arms, reinstall them.

2. Raise the drag-links on the deck with a pry bar and place a block (6 x 2 x 4 inch) under each one to lift the arm up. Use caution, as there will be energy stored in the torsion spring.

3. Raise the front of the machine so there is enough clearance to slide the deck underneath, and line up slots with the drag-link.

4. Slowly lower the machine over the drag links until the holes line up in the frame. Insert the pins and secure it with bolts (5/16 inch).

5. Raise the machine slightly until the block can be easily removed from underneath the drag-links.

6. Lower the machine until the chains can be attached with clevis pins and retainer clips. The machine my need to be started and the lift arms lowered to the lowest position so the chains will reach the deck.

7. After the deck is attached, slide the driveshaft over the gear box spline until the holes are aligned. Insert the roll-pins and tighten the two bolts on the driveshaft.

8. Start the machine and raise the deck high enough to remove the furniture dollies.

9. To adjust and verify the height of cut, consult the Owner's Manual.

Lubricate the machine every 50 hours. Grease more frequently when operating conditions are extremely dusty or sandy.

Grease Type: General-purpose grease

Where to Add Grease

Grease the locations indicated in Figure 15.

• Disconnect the battery before repairing the machine. Disconnect the negative terminal first and the positive last. Connect the positive terminal first and the negative last.

• Charge the battery in an open, well-ventilated area, away from sparks and flames. Unplug the charger before connecting or disconnecting the battery.

• Wear protective clothing and use insulated tools.
