LIFT VARIATIONS WHEN USING
ATTACHMENTS
When a front-mounted attachment such as a snowthrower or dozer blade is used with the tractor, the lift mechanism 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

Manual 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 attachment. Note that the washers (G) are not used with the
lock plate.

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.
