secure mounting and adequate operator clear-
ance when properly installed. Check clearance
dimensions shown in figure 1 to be sure you have
installed sub-frame correctly. Follow all mounting
instructions in this manual. Do not operate back-
hoe unless there is adequate clearance. Failure to
check and comply with these instructions may
result in serious injury or death.

from a position other than the operator seat is
during backhoe attachment and removal. Opera-
tor must
• Read Sub-Frame Mounting Kit Manual
instructions on attaching and removing back-
hoe and use extreme care
• Always stand between rear tire and back-
hoe stabilizer arms or along side of tractor to
avoid being trapped should the boom swing
control be accidentally activated.

before installing or removing backhoe from trac-
tor. Failure to comply may result in equipment
failure and/or personal injury.
