IS THE V70 DRUM MULCHER COMPATIBLE WITH MY LOADER?

The V70 Drum Mulcher requires a high flow loader with:

Shatterproof (polycarbonate) cab
30+ GPM flow rate
2,800+ pounds operating capacity

DOES THE V70 DRUM MULCHER COME TUNED TO MY LOADER FROM THE FACTORY?

The V70 DRM will come tuned for optimal drum speed and be ready to use from the factory within a GPM increment. The flow range choices (in GPM) are:

30-33.9
34-37.9
38-41.9
42-45
42.1-50

WHAT CUTTING WIDTH SHOULD I CHOOSE?

60” drum mulchers are more popular since they’re more maneuverable in tight spaces, draw less HP from the loader and spin up and recover faster than a 72” drum mulcher. When primarily clearing trees, most of the production occurs in the middle of the drum and having an extra foot of cutting width isn’t necessary.

72” drum mulchers process more material at a faster rate than a 60” drum mulcher This can be an advantage when working on larger job sites with a lot of ground vegetation to clear and where significant back dragging and ground mulching is required. The heavier drum handles larger material loads and provides more cutting momentum when grinding stumps and through thick vegetation. 72” drum mulchers are more expensive upfront and will likely cost more to operate and maintain.

SHOULD I CHOOSE A FIXED MOTOR COMPARE OR A VARIABLE MOTOR?

The Fixed Speed Bent-Axis Piston Motor (63cc max displacement) is the less expensive option for lighter vegetation and brush removal above ground. It will stall easier than a variable motor during heavy material loads, like when grinding stumps or mulching below grade, since it has less torque.

The Variable Speed Bent-Axis Piston Motor (85cc max displacement) is the most popular motor due to productivity gains when stump grinding and ground mulching. During heavy material loads, the motor smoothly shifts to max displacement and a slower speed to provide more torque.

SHOULD I GET SMOOTH OR BITE CONTROL DRUM ROTOR?

Here are some key differences between the two drum styles to help decide:

Smooth Drum

Ideal where significant ground contact is expected and when mulching below grade
Mulches entire pieces of vegetation at max cut depth and is more productive with smaller materials
Provides maximum energy transfer to the material
More likely to throw larger material and grab chunks
More likely for woody material to jam, since bite isn’t limited
Works well with steel planer and carbide teeth
Easier to keep balanced
Requires more HP from loader since bite isn’t limited
Lower upfront cost than bite control drums

Bite Control Drum

More productive and greater control during heavy, deep grinding in larger material
- Controlling the cut depth when processing wood keeps the rotor working at greater efficiency and at a more stable torque load. Heavy wood use creates a high load in the drum and teeth and benefits from a controlled bite
AR450 bite control rings help maintain drum speed and prevent stalling by limiting the depth and amount of material the mulcher can cut in a single pass.
Smaller bites produce consistent chip size and finer mulch on the first pass
Less likely for woody material to jam
Rings are designed to feed material toward the center of the drum. Proper feeding toward the center contributes to better mulching quality. It allows for consistent and uniform processing of the material, resulting in a more finely mulched finish
Much more productive with steel teeth than carbide. Bite control doesn’t work as well with carbide teeth since these provide less suction off the ground and suction is needed when working in rocky conditions
Slightly heavier and rings offer extra protection to the teeth and tooth holder
Rings may wear unevenly and require drum rebalancing
Requires less HP from loader
Higher upfront cost than smooth drums

WHICH TOOTH OPTION SHOULD I CHOOSE?

There are three tooth options which can be mixed and matched on the drum. The optimal choice depends on ground conditions, ground contact required and chip size requirements.

Steel planer teeth are the most productive and provide the smallest and finest mulched finish. They can be resharpened and rotated 180 degrees for twice the life.

Carbide Planer teeth are a hybrid between the steel planer and carbide hammer. It provides high productivity and can handle minimal ground contact.

Carbide Hammer teeth are for significant ground engagement and will provide the largest chip size. They also require the most loader power to operate since they are pulverizing material instead of slicing and cutting.

Steel Planer

For max productivity and the finest mulch without ground contact
Have two razor sharp edges to quickly slice through wood and pick up material off the ground
Made from high-grade alloy steel and heat treated
Reversible and need to be sharpened regularly to maintain high production
Stay off the ground and out of sand with steel teeth or the edges will dull quickly

Carbide Planer

Sharp cutting angle and curved body profile for higher productivity than hammer teeth with minimal ground contact
Requires no maintenance – no sharpening required
Abrasion resistant carbide tips for durability in rocky & sandy environments
Produce slightly larger wood chips than steel planer with similar productivity

Carbide Hammer

For significant ground engagement in rocky and sandy conditions, less productive than planer teeth
Produces largest mulch and the least amount of ground suction – pulverizes and rips material instead of cuts
Requires no maintenance – no sharpening required
Ideal option if mulcher is primarily used to mix mulch into the soil
Most abrasion resistant option with lowest cutting performance and productivity
Requires more power from the loader to operate

HOW LONG DO THE TEETH LAST?

Tooth life varies based on many different factors. During testing, Virnig has seen steel teeth last updwards of 400 hours and carbide 600 hours.

The V70 DRM utilizes Quadco® teeth which provide proven performance and durability.

CAN I MIX TEETH ON THE DRUM? WHERE SHOULD I INSTALL TEETH?

Yes, tooth styles can be mixed on the drum as long as they’re installed in pairs & on opposite sides of the drum to maintain balance. There are many different ways to install teeth on the drum. For the segmented installation, operators enjoy having steel on the middle of the drum for high productivity and carbide on the outside for rock contact and less maintenance.

Here are the most popular tooth installation locations:

OPTIONS

FIRST, YOU PICK THE MOTOR

FIXED MOTOR

Economical motor for mulching lighter vegetation above ground.

VARIABLE MOTOR

Provides more torque for productive stump grinding and mulching below grade.

SECOND, YOU PICK THE DRUM

SMOOTH DRUM

Designed for heavy ground engagement and mulching into the soil.

BITE CONTROL DRUM

Helps maintain drum speed by limiting the depth of material being processed.

THIRD, YOU PICK THE TEETH

STEEL PLANER TEETH

For max productivity and the finest mulch without ground contact.

CARBIDE PLANER TEETH

For higher productivity and minimal ground contact.

CARBIDE HAMMER TEETH

For significant ground engagement in rocky conditions.
