LIFT VARIATIONS WHEN USING
ATTACHMENTS

When a front-mounted attachment such as a snowthrow-
er or dozer blade is used with the tractor, the lift mecha-
nism must be locked to provide downward force.  When
the mower is reinstalled the downward pressure lock
must be released so that the mower can float.

Hydraulic Lift Models

When using a snowthrower or dozer, the downward
pressure lock plate (D, Figure 13) and an additional pin
(C) is installed.  These parts are included with the attach-
ment.  Note that the washers (G) are not used with the
lock plate.

When mowing, the downward pressure lock plate (D) is
removed and replaced with two washers (G).  The addi-
tional pin (C) is also removed.

Fully lower the hydraulic lift.  The lift assembly is spring
loaded so it will need to be held in the down position to
perform of the following procedures.

Manual Lift Models

NOTE: These instructions apply to Conquest / 1700 /
2700 Series tractors or Broadmoor / 1600 / 2600 Series
tractors equipped with a lift lever kit.

The lift link is installed differently depending on what
attachment is being used.  Refer to Figure 14 for link
installation information.
