Installation Instructions
The following tools will be needed to install the Boost Post Bumper kit:
• Deep 13 mm socket
• 8 mm wrench
• 10 mm socket with extension
To install the kit, follow these steps:
1. Using a deep 13 mm socket, secure the rubber
bumper (MD #166617) (A) to the bracket
(MD #166601) (B) with hex flange nut
(MD #135337) (C). Torque nut to 12–16 ft·lbf
(16–22 N·m). The bumper, bracket, and nut are
all provided in the kit.
DANGER: To avoid bodily injury or death from unexpected startup of machine, always
stop engine and remove key from ignition before leaving operator’s seat for any reason.
2. Stop the engine and remove the key.
3. Open the right-hand platform. For instructions,
refer to the windrower operator’s manual or
technical manual.
4. Remove the bolt (A) securing the right-hand
platform link (B) and move the link away from
the batteries.
5. Disconnect the positive battery cables (C) from
the battery boost posts and move them out of
the way.
IMPORTANT:
Ensure the red battery cables are away from the
battery and that they cannot accidentally
reconnect with the battery posts.

6. Find the bumper kit installation location (A) to
the left of the boost post (B).
NOTE: M205 Windrowers manufactured in the
2011 model year do not have holes for the
bumper kit and the boost post is positioned
higher on the frame member. For this model
year only, install the rubber bumper (without the
bracket) directly to the frame next to the battery
boost post terminal so that it contacts the edge
of the platform.
One hole must be drilled to accept the rubber
bumper. When drilling, be careful not to hit
anything behind the frame member.
7. Use the two hex head flange bolts
(MD #135959) and hex flange nuts
(MD #152668) to attach the bracket (A) to the
left-hand side of the windrower frame in the
orientation shown at right. Using an 8 mm
wrench and 10 mm socket, torque to 5–7 ft·lbf
(7–10 N·m). Bolts and nuts are provided
in the kit.
8. Reconnect the positive battery cables (C).
9. Attach the platform link (B) and secure with
bolt (A).
10. Close the right-hand platform. For instructions,
refer to the windrower operator’s manual or
technical manual.
