DEALER SET-UP INSTRUCTIONS for SNAPPER

21” STEEL DECK WALK BEHIND MOWERS

This SNAPPER Walk Behind Mower uses a handle engine control bail system to kill the engine for the SAFETY of

the operator. These mowers are designed for quick set-up. The Pre Sale Checklist must be completed and filled

out by the dealer as the items are checked off and/or performed and the Consumer/Operator Product Registration

card filled out and sent to the Customer Service department at SNAPPER when completed. CAUTION: Cutting

blades are extremely sharp. Wear heavy leather gloves when handling or working with blades. Be careful to avoid

cutting yourself on sharp edges of blade.

PUSH MODELS

STEP 1: Remove mower from shipping carton. Mower

shown as removed from shipping carton with handles

folded in Figure 1.

FIGURE 1

STEP 2: Remove and discard cardboard from between all

handles. Raise upper handle until it is in line and seats

into lower handle. Securely tighten upper handle T-Knobs

on both sides. See Figure 2.

FIGURE 2

STEP 3: Raise upper and lower handle until it seats into

position in the lower handle brackets. Securely tighten

lower handle T-Knobs on both sides. See Figure 3.

FIGURE 3

IMPORTANT: DO NOT tip machine with carburetor or

spark plug down. Oil from crankcase will saturate the air

filter and cause the engine to be hard to start or not start

at all. If contamination does occur, the air filter will have to

be replaced.

STEP 4: Tip mower back against the upper handle to gain

access to cutting blade. Remove foam shipping block

from cutting blade. This must be removed before starting

the engine.

STEP 5: Handle height is adjustable for different height of

operators. Loosen the two nuts on the inside of each of

the lower handles. See Figure 4. Move the handle up or

down to the desired height.. Retighten all nuts securely

after adjustment. Pull blade control against upper handle,

pull rope start handle and loop into rope guide. See

Figure 5.

IMPORTANT! Some models are equipped with braces

that attach to the lower handle brackets and must be

loosened before handle height can be adjusted.

STEP 6: Set-up is now complete for push models

without self-propelled drive system. For self-propelled

models continue to the “Self-Propelled Models” Section.

Proceed to the Pre Sale Checklist section of this

instruction to prepare mower for use.

SELF-PROPELLED MODELS

NOTE: The set-up procedure for self-propelled models is

basically the same as the Push Models. Follow the exact

procedure as described in Steps 1 thru 6 from the Push

Models section.

STEP 7: Check the clearance between the clutch cable

and clutch spring. NOTE: Clearance between spring and

cable is very important. Excessive clearance will cause

drive system NOT to operate when wheel drive control

handle is depressed. No clearance at all will cause

mower to continue to propel itself when wheel drive

control handle is released to stop mower movement.

Slide vinyl spring cover (located at the end of clutch

cable) up clutch cable to gain access to the end of spring

and cable loop. With wheel drive control handle

released, clearance between spring hook and cable loop

should be 1/16” to 1/8”. If clearance is more or less than

specified, unhook spring from clutch cable eye, then

adjust by rotating outer spring clockwise or counter

clockwise to achieve the proper clearance. Rehook

spring to clutch cable eye. Slide vinyl cover over the

spring when correct clearance is reached. See Figure 6.

STEP 8: Driven disc to drive disc adjustment is set up at

the factory. In case driven disc may need adjustment,

proceed as follows:

A. Place speed control rod in the number six speed

position. See Figure 7.

FIGURE 7

B. Remove driven disc spring from driven disc

assembly as shown. Loosen connector hex-nut. See

Figure 8.

FIGURE 8

C. Slide driven disc assembly over until 1/8” from

outside edge of drive disc. Maintaining the 1/8”

measurement, remove any looseness from the linkage.

This can be done by holding the transfer rod and

applying pressure to the left (as viewed from operators

position), then retighten the connector hex nut

securely. See Figure 9. Move shift rod to the number

one speed position, then back to the number six speed

position. Recheck the 1/8” measurement described

previously. Reinstall driven disc spring to driven disc

assembly.

STEP 10: Install the grass bag adapter and secure to

STEP 11: Attach support rod to deck adapter by first

removing the nut and bolt at the rope guide pulley.

Reassemble with the support rod underneath the pulley

and the flattened end of the rod towards the engine.

Attach the support rod to the top of the engine. Remove

the nut and washer from the right rear corner of the

recoil housing as shown. Place the support rod over the

threaded engine stud. Install nut only (washer not

needed) and re-tighten the nut. See Figure 15.

FIGURE 15

STEP 12: Fold bag opening into a "Z" and install slider.

See Figure 16.

FIGURE 15

STEP 13: Install grass bag on the mower. Slide bag

connector over flange on the bag adapter. Attach grass

bag handle to middle handle cross bar. See Figure 17.

FIGURE 17

IMPORTANT: DO NOT tip machine with carburetor or

spark plug down. Oil from crankcase will saturate the air

filter and cause the engine to be hard to start or not start

at all. If contamination does occur, the air filter will have

to be replaced.

STEP 14: Tip mower back against the upper handle to gain

access to the underside of the cutting blade. Remove foam

shipping block from cutting blade. This must be removed

before starting the engine.

rope out and route rope around pulley guide on bag

adapter and loop rope into guide on upper handle. See
