New Holland 615 Operator's Manual page 20

The hex-shaped hitch pins mounted on the bottom of
the main frame arms can be adjusted to position the
mower behind the tractor at different alignments to
account for different tread widths of the tractor.
To reposition the hitch pins to the proper location, do
the following:
1. Loosen the four clamp bolts, 1, on each main
frame arm until the hitch pins can be moved.
2. Retighten the clamp bolts evenly so that both
sides of the clamp block, 2, have equal clearance
to the main frame arm.
IMPORTANT: Always position the hitch pins so that
the long round pin is toward the outside of the main
frame. Do not position the long round pins inside the
main frame, or damage to the mower PTO drive shaft
could occur.
3. Measure from the center of the tractor to the right
side of the right tire.
4. Position the hitch pins for various width treads:
For tractors that measure 940 mm (37 in) or
•
less, place both hitch pins to the right so that
only the round pin protrudes on the left side
of the main frame arms. This will position the
mower towards the left, moving the cutter bar
closer to the right side tractor tire.
IMPORTANT: the tractor lower link arms may need
to be offset slightly to the left to prevent the mower
PTO shaft from contacting the inner end of the left
hitch pin.
For tractors that measure 1016 mm (40 in),
•
center the hitch pins in the main frame arm.
