Toro 325d Groundsmaster Parts Manual

I am looking at buying a 95 Toro Groundsmaster 325D (Toro model #30788) with around 2000hrs in good condition. It has the 25hp Mitsubishi diesel and the 72' deck. Are these good mowers? Do they cut pretty and do they hold up mechanically? I am not going to use it commercially just to mow about 2 acres once a week. I have owned a Grasshopper 822D (Kubota diesel, 52' deck) and Cushman Frontline (OMC gas, 60' deck) and enjoyed both of them but it's time to move on and I wanted opinions on the Toro. Tell me likes/dislikes and any weak points inherent in this particular model Toro. Also, what is a ballpark figure on what this mower is worth in good sound condition?

Important: The Groundsmaster 360 must be equipped with the Electrical Accessory Kit, Part 115-0019, to operate the Quick Attach Front Frame Kit.

This product complies with all relevant European directives. For details, please see the Declaration of Incorporation (DOI) at the back of this publication.

Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or missing.


  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:

    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).

  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.

    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.

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.

    Refer to the Operator's Manual supplied with the cab for instructions on fuses.

    If the machine has any electrical system issues, check the fuses. Grasp each fuse and remove them one at a time, checking to see if any are blown. If you need to replace a fuse, always use the same type and amperage rated fuse as the one you are replacing, otherwise you could damage the electrical system.

    Note: If a fuse blows frequently, you probably have a short in the electrical system and should have it serviced by a qualified service technician.

    1. Thoroughly clean the machine and cab, paying special attention to the following areas:

      • PTO shaft assembly

      • All grease fittings and pivot points

      • Oil the spline on the PTO output shaft to prevent rusting

    2. Check all fasteners for looseness and tighten them as necessary. Torque the 5 bolts securing the winter frame to the traction unit to 359 N⋅m (265 ft-lb).

    3. Grease or oil all grease fittings and pivot points. Wipe off any excess lubricant.

    4. Lightly sand and use touch up paint on painted areas that are scratched, chipped or rusted. Repair any dents in the metal body.
