The WM8600 backhoe attachment is manufactured using a heavy formed structural steel plate, the strongest plate steel available. The pieces are CNC laser cut so that they fit together perfectly, and are then precisely welded. This fact combined with the structural design allows for the perfect combination of weight and rigidity.
 
The WM8600 has a three-point hitch. This chipper is designed to work on tractors with at least 35 hp. at the PTO and will work on any category 1 or 2 tractor. 
 
The WM-8600 offers a full 9' digging depth and has a 3-Tooth 12  inch bucket.
 
ITALIAN HYDRAULIC CONTROLS 

WM-series backhoe attachments are now equipped with hydraulic control valves that are made in Italy by Hydro-control. Known for their high precision engineered control valves, Hydro-control designs and manufactures directional control valves for mobile applications and offers some of the most dependable products on the market. This is the highest quality hydraulic control valve available for a PTO backhoe attachments, and offers extremely smooth and reliable operation. The hydraulic control valves on backhoe attachments are the heart of the machine; this is why we chose Hydro-control. These control valves are second to none and offer extremely smooth operation for experienced operators, but are also very forgiving for novice operators.
 
REPLACEABLE BUSHINGS
 
Over time the pivot points of a backhoe will wear and require pin replacement. This is evident when the various parts that make up the boom, dipper, and bucket become loose and rattle. Due to the high load application of the pivot points, this is a common wear item for backhoes and excavators. Not only does the pin wear out, but the pin boss will also experience wear, so simply replacing the pin does not return the backhoe to its original condition. That is why the WM8600 backhoe is manufactured with replaceable bushings that are pressed into the pin bosses. So when the time comes to replace the pins, you can also replace the bushings. 
 
ONE PIECE GEAR PUMP 

HOC backhoe attachments are equipped with an extremely reliable one-piece gear pump made from high strength aluminum center housing and cast iron end plates. These pumps are equipped with an internal spline and are made to slide right onto the 1-3/8" spline of your tractor. No need to add oil to these pumps since the lubrication is provided by the pumped hydraulic oils. 
 
 
GRAPPLE THUMB (MECHANICAL OR HYDRAULIC) 

The grapple thumb is incredibly handy for picking up rocks, tree limbs, and brush. The mechanical thumb requires the operator to position the thumb by lowering and inserting a pin to secure the thumb. The hydraulic thumb is simply adjusted from the operator's seat. The mechanical thumb is currently offered for free (usually $250). Or you can choose the hydraulic thumb upgrade for only $680. Both upgrades are available for a limited time. 
 
RUBBER STREET PADS

Removable/replaceable rubber street pads on the stabilizer legs help reduce damage to the lawn, blacktop, and concrete. 
 
REPLACEABLE HARDENED BUCKET TEETH 

These hardened teeth will last a long time, but are a breeze to change when the time comes. 

SMOOTH HYDRAULIC CONTROLS
 
The WM8600 is equipped with a self-contained hydraulic pump and tank. No need for hydraulics from your tractor. This design is superior because it ensures the proper flow and pressure are achieved at 540 RPM PTO speed. This ensures that the hydraulic valves operate smoothly for the operator. Since all tractors put out different hydraulic flow and pressure, it is almost impossible to match a backhoe attachment to a tractor correctly. Over flow and pressure, or under flow and pressure is almost always encountered. This is not a problem with the HOC WM-series backhoe attachment. Also, the hydraulic pump mounts directly to the PTO spline of any category I tractor. No PTO shaft means no shaft sizing required, and no possibility of the shaft binding or jamming. This design also makes mating the backhoe attachment to the tractor easier, just attach the pump to the PTO, adjust the backhoe attachment height using the support legs and boom, back the tractor in, and attach the pins. This is not possible with backhoes that utilize a PTO shaft to power the pump.
 
180 DEGREE BOOM SWING
 
The boom on our WM8600 allows for 180 degrees of swing from one side to another. This allows you to dig into those tight spots and dump the dirt where you want.
 
EASY ACCESS CARTRIDGE TYPE OIL FILTER 
 
The WM8600 series backhoe attachment utilizes a cartridge type oil filter that is positioned directly inside the hydraulic oil tank through an easy access port. Positioning the filter in this location provides for greater protection from damage and ease of accessibility. These easy to change oil filters makes servicing your WM-series backhoes attachments breeze. 
 
RUST RESISTANT POWDER COAT FINISH 
 
The WM series offers a superior powder coat finish that is baked onto the steel. This finish is thicker and much more durable than paint to keep your backhoe attachment free from rust and looking good for years.
