Debris Loader Set-Up and Maintenance: DL25 and DL35

DL2500_534x575Most people think peak landscaping business is in the spring and summer, but you can be just as busy in the fall picking up leaves to protect lawns from sun and drainage problems. Billy Goat’s DL25 and DL35 are two of the biggest debris loaders on the market, letting you cut job times to keep your customers happy. Here’s what you need to know to get these machines running and keep them running.

Mounting the Loader

The debris loader should be permanently mounted before assembly or operation. These loaders are designed to be mounted using four 3/8 inch diameter bolts, along with a matching set of washers and lock nuts. The mounting holes are located on the sides of the base next to the access holes in the side plates.

Debris Loader Assembly

1. Attach the hose to the impeller housing intake using the quick release hose clamp. Make sure the clamp goes over the intake and the black safety switch.
2. Using the included screws, eye bolts, washers and lock nuts, attach the handle to the nozzle.
3. Stretch out the hose straight ahead of the intake. Attach the nozzle to hose using the other hose clamp, being sure to position the handle directly above the hose. This prevents twisting during use.
4. Slide the hose boom through the two rings on the top of the housing.
5. Slide the hose band over the hose. Use a cap screw and lock nut to attach the band to the chain. Connect the other end of the chain to the boom. Check the position of the chain and band: with the boom pointed straight back from the impeller intake and the hose stretched out, the chain should be straight up and down, and the band should hold the hose level with the intake.
6. Apply grease to both sides of the toothed plate at the end of the exhaust elbow, the top of the housing and the bottoms of the clamp plates.
7. Have someone on hand to help you maneuver the exhaust elbow into place. Place the small bottom plates, exhaust elbow and top plates on top of the housing. Line up the holes in the clamp plates and elbow, and position the elbow mesh so that its teeth with the worm gear.
8. Use 6 one-inch carriage bolts and 6 lock nuts to bolt the elbow to the impeller chamber.
9. Mount the battery using the included hold down rods, washers and lock nuts. Attach the red battery cable to the positive terminal, then the black cable to the negative terminal.

Maintenance Schedule

Before each use: Check the impeller liner, engine oil, and air filter. Clean the hose and remove any debris around the engine.
Every 5 hours of operation or daily: Inspect the machine for unusual vibration and loose or damaged parts.
Every 10 hours: Check the battery.
Every 25 hours: Check the battery terminals for corrosion.

Impeller Removal

The impeller needs to be inspected and possibly removed if you experience the following problems:
– The loader is vibrating.
– There is a major clog inside the housing.
– The wear plate is due for replacement.
– The engine is locked up.

Wait until the engine is cool. Always use a new bolt and lock washer when reinstalling the impeller.

1. Disconnect the spark plugs and the negative battery terminal.
2. Disconnect the intake hose from the impeller inlet and boom.
3. Using a 9/16 inch socket or wrench, remove the 12 bolts holding the intake plate. Once the plate is loose, move it to the side without putting strain on the safety switch wire.
4. Use an impact wrench to remove the impeller bolt.
5. Once lined up with the opening, the impeller should slide out. If it doesn’t, get a 3/4″-16 x 3″ bolt. Slowly screw it into the nut welded to the impeller. This will push the impeller off of the drive shaft.
6. Reinstall in reverse order. On the DL25, tighten the impeller bolt to 60 ft-lbs. On the DL35, tighten the bolt to 175-180 ft-lbs.


Billy Goat recommends using a U1-size battery with at least 240 cold cranking amps.

With regular use, the engine’s charging system provides enough power to keep the battery in good condition. During storage, the battery should be recharged every 4-6 weeks. The safest way to do this is with a trickle charger. A two amp charger can fully recharge a battery in one day, while a one amp charger will take two days. Once fully-charged, check the voltage output of the terminals with a multimeter. It should fall between 12-13 volts.
