Carbide Cutter OM

Owner Information

Thank you for your decision to purchase a Carbide Cutter 
from Loftness. To ensure maximum performance of your 
machine,  it  is  mandatory  that  you  thoroughly  study  the 
owner’s manual and follow its recommendations. Proper 
operation and maintenance are essential to prevent injury 
or damage and to maximize machine life.

The  Loftness  Carbide  Cutter  is  an  effective,  reliable 
machine  used  for  maintaining  grass,  weeds,  brush  and 
trees.  Efficiently  cuts  and  mulches  up  to  6"  diameter 
material. Intermittently cuts larger diameter material. For 
best results, operate the machine as low to the ground 
as  possible  without  the  teeth  striking  ground  or  other 
obstructions. Lifting or tilting the shredder increases the 
risk  of  flying  debris.  Because  of  the  high  speed  of  the 
teeth, the life of the teeth will be reduced if it is operated 
in  rocky  terrain  or  in  areas  where  many  obstacles  are 
present.  Areas  to  be  mowed  should  be  free  of  debris 
such as rocks, bottles, large branches etc. The teeth cut 
and pulverize the grass, weeds and brush. The shredder 
deposits cut material over the entire width-of cut, which 
eliminates bunching or windrowing behind the machine.

Operate and maintain this machine in a safe manner and 
in accordance with all applicable local, state, and federal 
codes,  regulations  and/or  laws,  and  in  compliance  with 
on-product labeling and these instructions.

Make  sure  that  all  personnel  have  read  this  owner’s 
manual  and  thoroughly  understand  safe  and  correct 
operating, installation and maintenance procedures.

Continuous  improvement  and  advancement  of  Loftness 
products  may  result  in  changes  to  your  equipment  that 
may not be reflected in this publication. Loftness reserves 
the right to make product improvements to the machine at 
any time. Although great care has been taken to ensure 
the  accuracy  of  this  publication,  Loftness  does  not 
assume any liability for errors or omissions.

Warranty Policy

Be sure to read and understand the Warranty Policy at 
the beginning of this manual. It is also important that you 
fill out the Warranty Registration form(s) completely with 
your dealer so as not to void the warranty.

Serial Number Location

NOTE: 

Pusher  bar  arm  has  been  removed  for  picture 
clarity.

The  arrows  above  indicate  the  location  of  the  serial 
number  tag  (1)  and  the  location  of  the  serial  number 
stamped into the frame (2).

Always  use  your  model  and  serial  number  when 
requesting information or when ordering parts.

Manual Storage

Keep the owner’s manual and the entire documentation 
packet  in  the  storage  compartment  provided  on  your 
Carbide  Cutter.  The  owner’s  manual  must  be  available 
for all operators.
