Assembly and Installation

ASSEMBLY

Follow these steps to assemble the spray tank prior 

to installing it on the tractor.  These steps must be 

used in conjunction with the 

A16 Boom Sprayer 

Parts Diagram on page 16.  

1.  Install the left (P/N B029, #30) and right (P/N 

B030, #38) Tank Supports on the bottom of the 

tank.  Install them with the single hole on the 

side of the channel facing toward the front and 

to the outside as shown in the parts diagram.  

Use four (4) F091 5/16” x 5/8” hex bolts.  

DO 

NOT TIGHTEN ANY HARDWARE UNTIL 

DIRECTED.

2.  Install the Rear Support Brackets and Support 

Tubes. The A16 ships with support brackets to 

mount on most compatible decks.  Differences 

in the carrier frames require additional hard-

ware on a few of the decks (DS52, DS60, and 

DS62).  See the appropriate following section 

for these decks.

NOTE: 

The DC52R and the DM52A use a 

different carrier frame than the DS52 and 

therefore do not required additional mounting 

hardware. 

● If you are installing on a DS52 or DS60, 

skip to the section, 

For DS52 and DS62 on 

page 8.

● If you are installing on a DS60, skip to the 

section, 

For DS60 on page 9.

For All Compatible Decks (other than the 

DS52, DS60, and DS62) 

Use the two (2) included Rear Support Brack-

ets (P/N B028, #31).

a.  Using two (2) F034 5/16” x 3/4” flange bolts 

and F009 nuts mount each Rear Support 

Bracket to the left and right Tank Supports 

as shown in the parts diagram

.

b.  Install the Support Tube (P/N B025, #35) 

on the left and right Tank Supports in front 

of the Rear Support Brackets using the two 

U-bolts (B035, #34) and four (4) F427 5/16”  

flange nuts into the appropriate set of 

holes.  

 -

For the 42” and 48” carrier frames

, use 

the 

rear

 set of holes closest to the Rear 

Support Brackets.  

 -

For the 52” carrier frame

, use the 

front 

set of holes.  

The tube should be installed with the holes 

in the 

vertical position

.  The tube should 

be positioned with 

2-1/8” extending past

the Tank Supports on each end. 

 Tighten 

all hardware installed.

c.  Invert the unit, slide the left (P/N B027, 

#33) and right (P/N B034, #37) Support 

Tube Assemblies into the end of the Sup-

port Tube in a fully extended position. 

d.  Install the locking pins (P/N B026, #32) into 

the tubes.

e.  Continue the assembly with Step 3 install-

ing the Boom Supports on 

page 9.

For DS52 and DS62

The following components must be purchased 

separately to mount the sprayer on these 

decks: 

● Two (2) x B037 Mounting Bracket, 52/62

The included Rear Support Brackets (P/N 

B028, #31) are not used with these decks. 

a.  Using two (2) F034 5/16” x 3/4” flange bolts 

and F009 nuts mount each B037 Mounting 

Bracket to the left and right Tank Supports. 

(These brackets will be in the same posi-

tion as the #31 brackets in the parts draw-

ing.)

b.  Install the Support Tube (P/N B025, #35) 

using the holes immediately in front of the 

Rear Support Brackets on the left and right 

Tank Supports with (2) two U-bolts (B035, 

#34) and four (4) F427 5/16” flange nuts. 

The tube should be installed with the holes 

in the 

vertical position

.  The tube should 

be positioned with 

2-1/8” extending past

the Tank Supports on each end. 

 Tighten
