High Performance Skid Steer Stump Grinder – S40
The S40 stump grinder is mounted with a bent axis piston motor. By matching a motor to your skid steers hydraulic flow these high efficiency motors make the most hydraulic power transforming it into the highest available stump grinding performance. Stocked with 20 carbide Wearsharp® Teeth the massive 1.25” thick steel rotor provides the back bone for the Skidsteer mounted stump grinder. The high number of teeth means that each tooth needs to do less work. Each tooth only needs to make a small cut, because the work is shared by more of these Wearsharp® Teeth, which last longer and typically only need 2 or 3 replaced at a time. The bolt-on designed teeth allow for straightforward replacement. The teeth can also be rotated up to 3 times to provide a renewed cutting surface even in the field.
The extra-large Blast shield is designed with dual rows of chain curtains to contain and control chips during grinding. The Blast shield is hinged to give the best protection and chip control throughout the grinding process. This hinge also allows the shield to be raised to get into tight areas and for easy access to the rotor and teeth.

VISIBILITY
Excellent Visibility from the operators seat.
SWING ARM
Dual swing cylinders for smoother, more controlled swing speed operation.
HOSE SHIELD
Double shielded hoses for extra protection.
AUX
Baumalight now offers a more direct and simple way of connecting to your skid steer’s auxiliary electrical connection. Simply connect the hydraulics and plug in the electrical. Now you can control the attachment from inside your cab.
BENT AXIS PISTON MOTOR
Our industry leading bent axis piston motors make the most efficient use of your hydraulic flow and pressure for your stump grinding needs.
ROTOR
The massive 1.25″ thick steel rotor provides the back bone for the Holt Eraser stump grinder. It’s the anchor of the carbide teeth.
BLAST SHIELD
Designed with an extra-large Blast shield with dual rows of chain curtains to contain and control chips during grinding. After grinding it also helps clean up giving you the ability to back fill without switching attachments.
HIGH SPEED TEETH
The concave shaped carbide tip of our High Speed Teeth provide aggressive cutting action by chipping the brush bit by bit. This round tooth is 3 teeth in 1. Simply loosen the lock nut and rotate the tooth to a fresh, sharp cutting edge. This can be done three times, extending the life of each tooth.
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.
Controls Overview
Auxiliary Connection (Included Standard)
*If you have a newer skid steer with auxiliary connection, please note what model of skid steer it is going on & the pin connection. Baumalight will equip the unit with your skid steer’s specific auxiliary connection prior to shipment. This Is The Ideal Solution. The operator can easily control all functions using the controls already equipped on the carrier joysticks. This allows the operator to never remove their hands from the controls to change a function.
Wired Control Box (Optional)
*If your skid steer is older & does not have an auxiliary electrical connection, you must add the wired control box. Although less than ideal, for controlling the attachment is using our wired control box. The operator would use the toggle switches on the control box to control the functions required. The wired control box requires a 12V connection to supply power.
Do You Have A Newer Bobcat Skid Steer With A Specific Bobcat 7-Pin Connector?
-If so, you will either have to add the control box kit, the Bobcat 7-pin CANBUS plug/circuit board kit, or contact your Bobcat dealer for a 7-pin to 14-pin adapter.
