(1) Excavator weight recommendation is based on standard excavator weights and boom and/or arm lengths. All applications must be approved by Stanley LaBounty prior to sale.
(2) Attachment weight can vary depending upon mounting bracket, appropriate cylinder required to maximize base machine operating pressures, and any options installed on the shear.
(3) Typical reach of bottom and back bracket is listed. Reach can vary depending upon the bracket needed for the base machine. Total reach may be substantially increased by mounting the attachment to the stick and bucket

linkage of a large base machine. Stanley LaBounty sales staff are available to assist in reach/base machine sizing.
NOTE: Weights, dimensions and operating specifications listed on this sheet are subject to change without notice. Where specifications are critical to your application, please consult Stanley LaBounty.

LaBounty MSD7 and MSD7R

(R indicates rotating model) Mobile Shears
are ideal for ferrous and non-ferrous
scrap applications. The MSD7/MSD7R
will easily H- and I-beams, plate, rebar,
pipe, round stock, wire and concrete.
The primary applications for the MSD7
and MSD7R include both ferrous, and
non-ferrous scrap yards and demolition
applications where maneuvering into
tight areas is required.

MSD Mobile Shears Feature four-way
indexible blades, replaceable wear parts
for easy maintenance, and a patented de­sign offering maximum cutting strength
and reach with minimal weight. MSD Ro­tating Mobile Shears feature 360° con­tinuous rotation and a severe-duty turn­table bearing.

Built to Last, LaBounty Mobile Shears
are manufactured in the U.S.A. using
abrasion-resistant, high-strength alloy
steel for minium weight and maximum
durability and reach.

MSD Shear Operation (Rotating Model Shown)

Mobile Shear controls will vary with the type of base machine on which the shear is
mounted and depending on whether it is mounted as a second or third member.

SECOND MEMBER SKID-STEER MOUNT

Stanley LaBounty offers several cylinder
sizes to optimize the performance of the
MSD7R Mobile Shear. Recommended pres­sure and flow ranges are as follows:

FUNCTION PRESSURE FLOW

OPEN AND 3601 - 4350 psi 13 - 22 gpm

CLOSE (248 - 300 bar) (49 - 83 lpm)

3001 - 3600 psi 14 - 24 gpm

(207 - 248 bar) (53 - 91 lpm)

2000 - 3000 psi 17 - 29 gpm

(138 - 207 bar) (64 - 110 lpm)

ROTATION 1350 - 2000 psi 4 - 6 gpm

(92 - 138 bar) (15 - 22 lpm)

For skid-steer mounting, typically the rear
auxilliary hydraulic circuit is used to oper­ate the open and close function of the
jaws. An optional selector valve can be
ordered from Stanley LaBounty to supply
oil to the shear’s rotator. For mini-excava­tor mounting or rubber-tire backhoe load­ers, please consult Stanley LaBounty for
proper hydraulic recommendations.
