MS972 Heavy Duty Fixed Tooth Mulcher for Skidsteer
The MS972 Baumalight brush mulcher is much like our MS960 only wider featuring a 72” rotor and 84” path width.
It has the same teeth and like the MS960 also has replaceable wear plates and a very short frame which brings the weight closer to the skidsteer allowing very productive mulching with a smaller track machine or wheeled skidsteer.
Operating a Brush Mulcher from a skid steer is probably the most comfortable way for vegetation management as your work is directly in front of you and new skidsteers are very operator comfort focused.
See our brush cutting size chart to see what limb size this heavy duty skidsteer mounted forestry mulcher can handle.

CASE DRAIN – BURST DISK
To prevent pressure relief activation on the motor seal, the MS972 comes with a case drain line and a burst disk valve. In the event there is a spike in pressure in your hydraulic lines, the case drain will relieve the pressure and drain it back into the return line and back to the tank. If the connection of the case drain (third line) is missed, then the case drain will blow which is easily fixed. A properly installed case drain protected by a burst disk will save the work of replacing your shaft seal and also improve the efficiency of your hydraulic system.
WIRE PROTECTION KIT
If you are mulching and you catch some old fence wire, it can really cause damage to the unit if the wire slips over the edge of the rotor and gets wrapped around the shaft. The wire can get bunched against the bearings, causing major damage. Our wire protection kit contains a welded raised area on the end of the rotor that protects the shaft and prevents wire from getting in.
What Is A Case Drain Line ?
On most skidsteer and excavator Hydraulic systems, Hydraulic motors and pumps require a case drain line. Sometimes referred to as a third line, the case drain line will relieve any excess pressure and drain it back to your return line, then into the reservoir. Without a properly installed case drain, that extra pressure could blow a seal or damage your hydraulic line. For higher flow motors or on piston and gear motors, a case drain line is always required. Although, no matter the size of your motor, a case drain is always a good idea as it will relieve the amount of pressure on your shaft seal, helping to prolong its life. A case drain line can also increase the efficiency of your hydraulic system as it will lower the back pressure on the tank line.
Since most machines have a unique style of coupler, BaumaLight does not include a coupler on our case drain line, although they are available. If your skidsteer is not equipped with a case drain, then it can be field installed.
How Important Is A Case Drain Line ?
If we say having a case drain is critical and you operate without one, you will blow out your shaft seal. Be sure to check the motor sizing charts on our website.
Exception If You Have A Hammer Valve
There is one exception in the need for a case drain on gear motors and that is if you excavator is equipped with a hammer valve, this is a larger free flow line back to tank.
Identifying Your Case Drain Line
The following galleries show a highlighted case drain line on multiple skidsteer and excavator models.
Planer Tooth Style
The Planer style tooth feeds its appetite for brush bit by bit, taking small bites and providing the most efficient mulching and cutting. Although planer style teeth are efficient, their flat profile make them vulnerable to shattering on impact with rocks and other debris. For that reason, this style of tooth is recommended for cutting applications where efficiency is more important than tooth life. Planer teeth are bolt-on replaceable for quick and easy servicing and replacement even in the field.
Ripper Tooth Style
Ripper style teeth is a general use tooth, offering operators a shredding mulching action. Their v-shaped design makes them less susceptible to impacts with hard objects like stones, making them the better choice when mulching below grade and in fence lines. Ripper teeth are bolt-on replaceable for quick and easy servicing and replacement even in the field.
