Morbark G 52 SP Stump Grinder

Morbark G 52 SP Stump Grinder

Backed by the experience gained in nearly half a century of equipment innovations, Morbark, Inc. has entered the stump grinder market.

The first Morbark Models are now available, with more to come.  These durable stump grinders were designed from our extensive experience in wood processing and with state-of-the-art computer generated failure analysis (CAE) tests.  This powerful software analyzes key stress points and ensures the machine structure is optimized—all before they are even built.

The Models G52SP and D52SP include many new and innovative design features that put them ahead of the rest…literally. These grinders get to the stump faster.  With a top speed of 3.2 MPH, they offer a significantly higher travel speed than other grinders in their class. After quickly maneuvering to the stump, Morbark machines also grind the stump faster.  With Morbark’s unique cutter wheel and tooth design, the G52SP and D52SP grind stumps faster than the competition.  This is due to a number of design features unseen in the industry until now.  The patent pending boom design creates a 52” cutting arc, which is 25 percent wider than anything in its class.  In addition, the unique hexagon shaped cutter wheel offers less resistance and friction through the stump.  Six multi-tipped cutting tools fastened with one bolt each provide the grinding performance of 24 teeth with the quickest, easiest cutter change in the industry.  These units also have the largest chip retention space—up to eight cubic feet—in their class, meaning more continuous grinding and less repositioning.

Machine operation is made easy through many important features. The standard operator’s control station, with well-spaced hydraulic levers, is located for maximum visibility of the grinding wheel.  Optional wireless or wired remote controls free the operator for optimum visibility away from dust and debris.  The exclusive stationary engine design creates a low center of gravity and superior stability to minimize rollovers and engine oil starvation.  In addition, steering on wet turf, loose gravel and uneven terrain is optimized with hydraulic equalization valves and an articulating front axle.

Morbark offers hydraulic oil capacity up to five times that of other machines in this class, providing for a cool running system and extending component life.  Outer dual wheels are easily removed without tools, allowing the grinder to pass through a standard 36” gate.  Morbark also offers an optional hydraulic back fill blade.
