Clevis Style HitchSingle Tang Hitch
Refer to Figure 2
1. Park the sprayerin an open,flat area with the jack in
the park position. Using a tape measure, check the
distancefrom the frontunder side ofthe frame tothe
ground and the back under side of the frame to the
ground. Adjust the jack so that dimension "A" is
11/2inchesgreaterthan dimension "B". The goal is
to have the solution drain into the sump of the tank
so there is no excess solution in the tank when
drained.
11569
4. Hitch the sprayer to the tractor using a hitch pin of
adequate strength (minimum 1 inch diameter). You
must also install a retaining clip on the hitch pin to
preventit from coming out and causing a chemical
spill.Retractthejackuntil theweight istransferredto
the hitch.
5. Recheck to see that the frame is sloping downward
in the front with dimension “A" being approximately
1 1/2 inches greater than dimension “B”.
6. Your Sprayer comes equipped with a hitch safety
chain.The safetychain should be securelyattached
to the sprayer hitch and the tractor drawbar support
whenevertowing or spraying.
Refer to Figure 4
7. Unpin the tongue jack, and pin it in the transport position.
2. Back the tractor draw bar up to the sprayer hitch to
determine the amount of adjustment needed.
Refer to Figure 3
3. The mounting holesin the hitch havethreepositions
that it can be located. Movethe sprayerhitch height
to the height of your tractor’sdrawbar and bolt the
hitch onto the sprayermaking sure to torque the
bolts to the correct specification on the “Torque Val-ues Chart” on page 62. The single tang hitch has

Tractor / PTO Pump Hook-Up
1. Position the PTO pump on the tractor’s PTO shaft
with the coupler bolt loose on the splined end.
2. Push the coupler of the pump on to align with notch
in the tractor PTO shaft and install bolt.
3. Make sure there is adequate hose length to reach
the pump.
4. If youhavea 540rpmpump ora 1000rpm1 3/8 inch
spline pump, torque the 1/2 inch Grade 8 coupler
bolts to 105 ft-lbs. If you havea 1000 rpm 1 3/4 inch
spline PTO pump, torque the 5/8 inch Grade 8 coupler bolt to 210 ft-lbs and the other 1/2 inch Grade 8
coupler bolt to 105 ft-lbs.
6. Attach the torque bar chain to the drawbar securely.
7. Hook the tarp strap in such a way that the slack in
the chain is taken up slowly when the PTO is engaged so the torque bar does not bang.
8. Tie up any loose hoses with cable ties to prevent
hose damage.
Tractor / Hydraulic Pump Hook-Up
1. Yourtractor should be equipped with at least two remote outlets (one pair).
2. If your tractor has an open-center hydraulicsystem,
remove the orifice restrictor in the pressure line. If
your open-center hydraulic system produces more
than15 GPM, it isnot recommended to hookthis hydraulic pump up to your tractor.The pump will spin
too fast. If your open-center hydraulic system is 15
GPMor less,itis recommendedto installa hydraulic
flow divider so that you can adjust the speed of the
pump. A Gresen model number CFDA or similar
flow divider will work. The maximum flow for the hydraulic motor is 6 GPM.
4. If your tractor has a closed-center system, or a flow divider has been installed in your tractor’s open-center
system, set the hydraulic flow control valve at a minimum flow for the pair of outlets that operates the
pump.
5. With water in the sprayertank, and water in the pump,
place the hydraulic lever in the float position and start
the tractor.
6. Place a stop in the neutral position of your tractor hydraulics so that the lever can only be moved to the
float and down positions. Refer to your tractor operator’s manual or tractor dealer on information for the
neutral stop.
IMPORTANT: DO NOT move the h ydr aulic lever into
the neutral position while the hydraulic pump is running. To do so may cause damage to the hydraulic
pump.
7. To set the hydraulic flow control on the tractor,first engage the pump by placing the hydraulic leverin the
down position. Once the system builds pressure,
close the agitation valve,shut off the boom section
switches and close throttling valves {if applicable}.
Sprayerswith RavenAutomatic Monitors do not have
throttling valves.The pump is now at dead head pressure.Adjust thehydraulic flowcontrol valvesothat the
spray pressure reaches 80 PSI maximum on the nozzlepressure gauge. If so equipped, reset the solenoid
throttling valves as described in the "Solenoid Throt-tling Valve" on page 51.
3. For the hydraulic motor to turn in the right direction,
thepressure hosemust beconnected tothe "A"port
ofthe motor and the return line connected to the "B"
port. Install hydraulic hose clamp label provided {refer to hydraulic pump section in parts manual} approximately18inches fromtractor quickcouplersso
that the hydraulic cylinder retract symbol and arrow
aligns with the pressure hose going to motor port
"A". If your tractor is a John Deere, leave the restrictor in the pressure side ofthehydraulicpump.If
your tractor has a closed center hydraulic system
and is not a John Deere, remove the restrictor.

Tractor / PTO Shaft Hook-Up
Refer to Figure 5
1. PositionPTOshafton tractor.Be sure shaft iscoupled
on tractor.
2. Adjust the vertical position of the pump driveshaft on
thesprayerso that it is level,to slightly higher than level with the PTOshaft on the tractor as shown. This reduces driveline vibration when turning a corner.
Adjust the vertical position by moving the four bolts
supporting the driveshaft bracket.
Note: If, after adjusting the vertical position of the pump
driveshaft, you find that the driveshaft is still a lot higher
than the PTO driveshaft on the tractor; adjust the hitch up
one position and readjust the pump driveshaft. Refer to
