Domestic Series 7000 MFD

ABOUT THIS SECTION:
Early (2002 and 2003) production of the domestic 
Series 7000 four wheel drive tractors used an MFD 
(Mechanical Front Drive) sourced from another manu-
facturer. Beginning with serial number 1B014G20001 
(February 1st, 2004) domestic Series 7000 tractors 
were built using an MFD assembled in Cub Cadet’s 
transmission plant in Leitchfield, KY.   It will be found 
primarily in CAT 
TM powered tractors.  
A similar appearing, but not identical MFD has been 
used in the Cub Cadet Series 5000 since the start of 
that models production.   It will be mentioned in this 
section so that it can be distinguished from the unit 
used in the Series 7000.  
Service of the earlier MFD is covered in the 2003 Cub 
Cadet technical Handbook. This section covers the 
MFD produced by Cub Cadet.   The two MFDs are very 
similar in appearance and function. Removal and 
replacement procedures for the two units are not sub-
stantially different from one-another, and they are 
directly inter-changeable in application. The brackets 
are different. If one is to be used in place of the other, 
they must be changed complete with the brackets.
Service Policy on the Cub Cadet produced MFDs will 
be to establish a pool of rotable exchange units that 
can be ordered by dealers to replace damaged MFDs.  
This applies to the Cub Cadet produced MFDs only, 
NOT to the outsourced MFDs that were used in some 
early production domestic Series 7000 tractors.
For tractors with warrantable repairs required to a 
Cub Cadet built MFD:
• The complete assembly is to be removed and 
replaced.
• The core shall be returned to Cub Cadet for 
rebuilding.  It is not to be disassembled in any 
way.
• The determination as to whether a new or fac-
tory rebuilt MFD is to be installed under warranty 
will be made on a case-by-case basis.  
• Outside of warranty, the dealer is free to repair a 
worn or damaged MFD, replace a worn or dam-
aged MFD with a factory rebuilt unit, or to 
replace a worn or damaged MFD with a new 
one.  
1. TO IDENTIFY THEM MFD:
1.1. The out-sourced MFD is part number 618-3207. 
The Cub Cadet built MFD is 618-0484.   The out-
sourced MFD can be distinguished from the Cub 
Cadet MFD in the following ways: 
1.2. The out-source MFD has numbers embossed on 
most major components, the Cub Cadet Unit 
does not. See Figure 1.2.
            
1.3. The Octagonal “pumpkin” is roughly 2” wide on 
the out-sourced MFD.  It is roughly 4” wide on 
the Cub Cadet MFD.  See Figure 1.3.
