hydraulic hoses (#8 & #9) through hose loop (#7) and
attach to tractor duplex outlet. Hydraulic cylinder
should extend when pushing control lever. Reverse

gearbox shaft must be aligned and level with each
other when hooking-up the driveline to the tractor.
3-Point Hook-Up to RCF(M)3696 Cutters
The following hook-up instructions are for RCF(M)3696
cutters with or without hydraulic hoses. See page 16 for
“3-Point Hook-Up to RCF(M)3610 Cutters”.
1. Make sure you have read and follow all Safety Alerts
and Important Notes listed under “3-Point Hook-Up
Instructions” on page 14 before continuing.
2. The RCF(M)3696 cutters are equipped with
Cat. I & II hitches. Make sure your tractor’s hitch is
compatible with the cutter’s hitch.
a. Cat. I Tractors: Lower 3-point arms have 7/8"
dia. holes & upper center link has a 3/4" dia. hole.
b. Cat. II Tractors: Lower 3-point arms have 1 1/8"
dia. holes & upper center link has a 1" dia hole.
Refer to Figure 1-9:
3. Remove lower linchpins (#5) and hitch pins (#6).
Remove upper hairpin cotter (#3), flat washer (#2),
and hitch pin (#4).
4. Slowly back tractor to cutter while using tractor’s
3-point control lever to align lower 3-point arm holes
with clevis hitch pin holes.
5. Engage tractor park brake, shut tractor engine off,
and remove key before dismounting from tractor.
6. Attach lower 3-point arms to clevises with hitch
pins (#6). Secure hitch pins with linchpins (#5).
7. Connect center 3-point link to upper hitch with clevis
pin (#4), flat washer (#2), and hairpin cotter (#3).
IMPORTANT: The tractor’ lower 3-point arms must
be stabilized to prevent side-to-side movement.
Most tractors have sway blocks or adjustable chains
for this purpose.
NOTE: The lower 3-point arms on a Cat. II tractor
are positioned outside the clevis hitch plates. All
other hook-ups will require the arms to be positioned
inside the clevis hitch plates.
