Tractor Hook-Up
!
DANGER
To avoid serious injury or death:
A crushing hazard exists while hooking-up and unhooking the
implement. Keep people and animals away while backing-up
to the implement or pulling away from the implement. Do not
operate hydraulic controls while a person or animal is directly
behind the power machine or near the implement.
!
WARNING
To avoid serious injury or death:
•
An unsupported parked tiller can tip over. Always use park
stand and/or support blocks to prevent it from tipping over
onto a person.
•
Always follow "Tractor Shutdown Procedure" provided in
this manual before dismounting the tractor.
•
Do not raise center of lower 3-point hitch pins more than
24" above ground with power take-off engaged. Do not
engage power take-off if hitch pins are higher than 24"
above ground. If tiller is raised too high, the driveline can
break causing flying projectiles.
IMPORTANT: The tractor's lower 3-point arms must
be stabilized to prevent side-to-side movement.
Most tractors have sway blocks or adjustable chains
for this purpose.
