the PTO is "ON" or the shift lever is not in "PARK START" the PTO clutch and engine ignition are both shut off. When the PTO is "OFF" and the shift lever is in "PARK/START" leaving the seat will not cause the engine to stop.

Hydraulic Lift (Figure 1) This iever controls the

hydraulic system used to raise and lower attach

ments. The lever has four positions — UP, HOLD, DOWN and FLOAT. The normal out-of-use po sition is the "HOLD" position. In this position the attachment wiii not raise or lower. When it is desired to raise the implement, move the lever to the "UP" position; to lower the attachment move the lever to the "DOWN" position. Place the lever in the "FLOAT" position to aiiow the attachments to follow the ground contours.

Ammeter (Figure 1). The ammeter indicates the rate of battery charge or discharge. The indicator should register on the (+) side of the dial when the engine is running at any speed above a slow idle.

When the engine is idling or with a fully charged

battery, the ammeter may not show charge. Should the ammeter register on the (—) side of the dial for an extended period of time with the engine running,

it indicates the alternator is not charging the battery.

Check the battery connections or contact your dealer.

OPERATION

Figure 2. To stop or slow down, gradually pull the control lever toward the neutral (N) position or depress the neutralizing pedal.

PRE-STARTING INSPECTION

Prior to starting the engine for each day's operation, the

following checks and services should be performed:

a. Check oil in engine crankcase. Add oil as required to

maintain proper level.

b. Check fuel supply. Use regular gasoline only. c. Check air filter for excessive dirt. Clean as required. d. Make visual check with regards to safety precautions,

obstructions, lubrication, and maintenance.

STARTING THE ENGINE Use the following procedure to start the engine:

1. Place the hydrostatic control lever in the "Park-Start"

position, shown in Figure 2.

NOTE: This is a safety feature. The engine wiii not start unless the control lever is pulled all the way to the rear of the "Park-Start" slot

2. Be sure the Implement Power Control Switch(T)Figure 1,.is pushed in (OFF).

NOTE: This is a safety feature. The engine will not start un less the switch is off (pushed in).

3. Raise throttle lever ©Figure 1, to approximately 1/3

fast position.

4. Pull choke control ©Figure 1, all the way out if engine

is cold. If engine is warm, little or no choke may b'' required.

5. Turn ignition key ©Figure 1, clockwise all the way.

Release key as soon as the engine starts and push choke button in. In cold weather it may be necessary to push choke in gradually until engine warms up. If engine fails to start on the first attempt, turn key to off, wait a few minutes and try again. Do not operate the starting motor continuously for more than 30 seconds at a time.

Always allow engine to warm up before applying load.

In below freezing weather, allow engine to run at a fast idle for a period of at least 5 minutes before using the tractor. Serious internal damage to the engine and hydrostatic trans

mission could result if this procedure is not followed.

NOTE: The lines next to the forward slot do not indicate a given speed and serve as guide lines only.

To move the tractor backward and increase reverse travel speed, gradually pull the hydrostatic control lever back In the reverse (R) slot from the neutral (N) position, shown in

Figure 2. To stop or slow down, gradually push the control lever toward the neutral (N) position or depress neutralizing pedal slowly with foot.

To stop the tractor, return the control lever to neutral either by hand or with the neutralizing pedal and then step on the brake to stop tractor from rolling.

OPERATING THE TRACTOR CONTROL LEVER

When the hand control lever is placed in the "Park-

Start" position as shown in Figure 2, a pin engages in the

teeth on the reduction gear inside the rear axle housing. This

mechanically locks the rear wheels and prevents them from

turning. When the control lever is moved into the neutral

(N) position. Figure 2, the pin is disengaged; however, the hydrostatic transmission will not allow the rear wheels to turn provided there is sufficient oil in the transmission and

the free-wheeling valves are not depressed.

To move the tractor forward and to increase forward travel speed, gradually push the hand control lever for ward in the slot from the neutral (N) position, shown in

Because of the dynamic braking characteristics of the

hydrostatic transmission the control lever is extremely

sensitive to the slightest movement when in the forward or

reverse slots. Always move lever slowly when in these slots.

When the tractor is stopped on a hill or grade and the control in neutral, a slight amount of tractor movement is considered normal, if wheel brakes are not applied after neutralizing transmission speed control.

The forward travel speed of the tractor is infinitely

variable from 0 to 6.8 mph. The reverse travel speed is

infinitely variable from 0 to 3.2 mph with the engine running full throttle.

STOPPING THE ENGINE

Always use the following procedure to stop the engine:

1. Move the hand control lever @ Figure 1, in "Park-

Start" position and set the parking brake. Figure 4.

2. »Disengage Implement Power Control Switches ©Figure 1, and driven attachments.

3. Lower attachment so that it is resting on the floor or

ground.

4. Lower the throttle lever © Figure 1, and allow engine to idle for a short period before turning it off.

OPÉRATION OR WHEN MOVING THE HAND CONTROL LEVER. USE OF THE PEDAL AND HAND CONTROL LEVER SIMULTANEOUSLY CAN RESULT IN MIS-

ADJUSTED HYDROSTATIC LINKAGE.

THROTTLE LEVER SETTING

When operating power driven attachments such as the

mower, snow thrower or the rotary tiller, run the engine at full throttle unless the attachment operator's manual specifies otherwise. Use the hand control fever, not the throttle lever to select a safe travel speed when using power driven attachments.

Safe or proper travel speed depends on the attachment used, the type of terrain and lawn, field or garden con ditions in which the tractor is operated.

STOPPING THE TRACTOR

To stop the tractor, depress neutralizer pedal completely

@ or move control lever @ to neutral. Figure 1, and de press the brake pedal. Then place the control lever in the "Park Start" position and set the parking brake. Figure 4.

EMERGENCY STOPS

For emergency or "panic" stops, the neutralizer pedal

and brake pedal can be used, see Figure 3. When the neu

tralizer pedal is dépressed, the control lever is shifted to the

neutral IN) position from either the forward or reverse

positions, then use the brake pedal to stop the tractor if

motion continues.

5. Turn the ignition key ©Figure 1, counterclockwise to stop engine.

IMPORTANT — Remove ignition key before dis

mounting from tractor. This will prevent children

and inexperienced operators from starting the tractor.

RAISING THE REAR DECK

The transmission and control linkage are readily accessible by raising the rear deck, shown in Figure 5. To raise the rear deck, place the hydrostatic control lever in the "ParkStart" position, release the two latches and raise the" rear deck to its stop.

REAR DECK

NOTE: Keep foot off neutralizer pedal when moving the hand control lever. Use of the neutralizer pedal and con

trol lever simultaneously can result in mis-adjusted hy

drostatic linkage. Become familiar with the use of the neutralizer pedal. Using the foot controlled neutralizing

pedal for ail slowing down and stopping operations will

make emergency or "panic" stops become "automatic" by use.

CAUTION: Always shut off engine before raising the rear deck. Be sure to lock the rear deck down with the latches provided before operating the tractor.

RAISING THE HOOD

The engine, battery and electrical components are readily

accessible by raising the hood, see Figure 5. To raise the hood

grasp each side and raise it ud and forward to its stop.

CAUTION: ALWA YSSHUTENGINE OFF BEFORE

RAISING HOOD. NEVER TOUCH MUFFLER, EX

HAUST PIPE OR ENGINE UNTIL THEY HAVE

HAD TIME TO COOL AFTER OPERATING THE

ENGINE.

FREE-WHEELING VALVE

The free-wheeling valves are located under the rear deck

on top of the transmission, see Figure 6. These valves

must be kept closed (buttons out) at all times except when it becomes absolutely necessary to push the tractor with the

engine stopped. If this should happen, open the valves by

pushing the buttons "IN", by rotating cam. See Figure 6.

-6-

Before attempting to push the tractor be sure the hy drostatic control lever is in neutral (N) and the free wheeling valves pushed in. If the lever is in the "Park-Start" position the rear wheels will be mechanically locked.

The tractor will not move under power unless the free

wheeling valves are closed (button out), by rotating cam.

FIGURES

IMPORTANT: DO NOT PUSH OR TOW TRACTOR LONG DISTANCES AS INTERNAL TRANSMIS

SION DAMAGE COULD RESULT. LOAD TRAC

TOR ON A TRAILER OR TRUCK WHEN MOVING LONG DISTANCES.

ENGINE

Check the engine crankcase oil level daily or every 5

hours operation. It is essential that the oil level be maintained

in the "safe" operating range as shown in Figure 8 at all

times or serious engine damage could result.

To check the oil, stop engine and wipe all dirt and dust from around the dip stick. Figure 9. Pull dip stick out, wipe off the oil, re-insert dip stick and push it down tight. Pull the dip stick out and observe the oil level. Add sufficient oil

of the proper viscosity to bring the oil up to the "fill"

(F) mark, see Figure 8. Be sure tractor is level to correctly read dip stick.

FIGURES

DO NOT OVERFILL — Oil level must never exceed full mark. Oil capacity of the engine crankcase is 4 U.S. pints.

LUBRICATION

FILLING THE TANK

The fuel tank filler cap is located behind the seat, see

Figure 7. Wipe the dust and dirt from around the cap before removing it to prevent dirt from falling into the tank while filling. Use an approved gasoline container and keep it clean.

The fuel tank capacity is 4.5 U.S. gallons.

Use regular grade gasoline. Be sure the gasoline is clean and fresh. Do not use premium gasoline. Do not mix oil with gasoline.

FIGURE 7

Use AriensGard-N-Yardoil (SAE 10W-30 SE classification)

when using lawn and garden attachments. Use Ariens Sno-

Thro oil (SAE 5W-20 SE classification) when using snow

removal attachments.

CHANGE ENGINE OIL

When the tractor is new, the oil should be changed after

the first 5 hours of operation.

Under normal operating conditions, the oil should be changed every 25 hours of operation. If extremely dusty or dirty conditions prevail, change oil more frequently. See

Engine Owner's Manual.

Drain the crankcase by removing the drain plug, shown in

Figure 10, and allow the oil to drain into a container. If possible, run engine just prior to changing oil, as the oil will flow more freely and carry away more contamination when hot.

-7-

NOTE: Bottom of engine shown. FIGURE 10

Replace drain plug. Remove dip stick and refill crankcase

with 4 U.S. pints of oii. Check oil pn the dip stick to see that the oil level is at the fuli (F) mark. Do notoverfiil.

TRANSMISSION OIL GRADE AND VISCOSITY

Ariens Gard-N-Yard lOW-30 or an equivalent detergent type motor oil meeting the requirements of the American Petroleum Institute (A.P.i.) Service Classification SE should be used. Oil viscbsity (weight) should be SAE 10W-30 and is recommended for year-round use.

Thereafter, the filter should be changed every 100 hours or annually, whichever comes first. It is not necessary to change the transmission oil.

Use the following procedure to change the transmisSiOft

oil filter.

1. Drive the tractor onto level ground. Place a container under the filter to catch oil spillage as filter is removed.

2. Unscrew and discard oil filter. Use an oil filter removal

tool if necessary.

3. Moisten the rubber gasket with oil and install the filter.

4. Siart engine and cycle the hydraulic lift until it operates smoothly. This bleeds the air out of the transmission. Check

TRANSMISSION OIL LEVEL

The hydrostatic transmission, differential and hydraulic lift system all operate from a common oil reservoir. Note that the rear end is the oil reservoir. The oil level in the reservoir should be checked every 25 hours of operation or monthly.

CAUTION: Proper oil level is essential for proper

oil level:

1. Drive tractor onto level ground.

2, On tractors with hydraulic lift systems, move hydraulic control lever to the "DOWN" position until the lift cylinder is fully retracted.

3. Move control lever to park start, keeping engine at fast idle.

4. Wipe dirt from around the oil level and filler plug. See

Figure?.

5. Remove plug. Oil level should be to the top of the pipe elbow at the filler plug, see Figure 11.

6. If necessary, use a small funnel to add sufficient SAE 10W-30 with SE classification motor oil to bring the oil up

to tVie proper level. Replace plug.

short tire life. Always see that the tire valve caps are in place and securely tightened to prevent air loss.

FUEL PUMP AND FILTER

The engine may fail to start due to lack of fuel at the

carburetor if the fuel pump shown in Figure 17 loses its

prime. This can occur when the fuel tank is run dry or may be due to evaporation of fuel from the system after a storage period. I n either case, make certain there is fresh fuel in the

tank and operate the priming lever on the fuel pump several

times to start fuel flow.

If a faulty fuel pump is suspected, see your Ariens dealer.

When dirt or other foreign material is allowed to enter the

fuel tank it will collect in the fuel filter shown in Figure 17.

This will eventually cause fuel stoppage. The filter can be dis

assembled and cleaned.

The hydrostatic controls should be adjusted so the tractor does not creep forward or backward when the control lever in the neutral (N) slot in the control console as shown Figure 2. In addition, the control lever should automatically be shifted to this position from either “forward" or "reverse*' when the neutralizer pedal is ^Hy depressed.

CAM SLOT

CAUTION: REAR AXLE MUST BE RAISED AND BLOCKED SECURELY SO THAT REAR WHEELS ARE FREE TO REVOL VE.

2. Loosen clamp bolt B, Figure 18 and rotate the eccentric until the flats on the eccentric are parallel to the cam slot as shown in Figure 18. Retighten bolt B. This will assure a maximum fine adjustment range.

3. With the control fork. Figure 19, move the cam. Figure 18, until the cam follower roller is lined up with the cam

dwell center mark. DO NOT adjust the hydrostatic control fork. Figure 19, if the control lever is not in the neutral slot of the console. This is the final adjustment to be made.

4. Depress free-wheeling valves by rotating cam up. See Figure 6.

5. Loosen pintle lever clamp bolt A, Figure 18, a sufficient amount to allow the pintle lever to move freely. Move the

hydrostatic còntrol lever. Figure 19, in the park-start position, start the engine and run at idle. Return the control lever to the neutral slot in the control console.

6. Release the free-wheeling valves by rotating cam down. Figure 6. NEUTRALIZER PLATE

1. Jack up the rear of the tractor until the drive wheels clear

the ground and BLOCK SECURELY. Wheels must be free to

revolve.

2. With the control lever in "park-start" position, raise the rear deck. Activate seat switch to allow engine to start.

3. Start engine; place control lever in the neutral position and increase engine speed to full throttle.

4. Loosen clamp bolt B, Figure 18 a sufficient amount to allow the cam follower to rotate. Turn the eccentric

"clockwise" or "counter-clockwise" as required until the

rear tractor wheels completely stop. Retighten clamp bolt B.

Check adjustment by moving the control lever to both

forward and reverse positions several times. Each time the lever

is returned to neutral, the rear wheels should stop com pletely if they drift, re-adjust the eccentric until a true neutral position is found.

Check that the cam follower roller is lined up with cam dwell center mark. Move the pintle arm back and forth until wheels stop turning. Carefully tighten bolt A, Figure 18. The neutral adjustment is extremely sensitive and this pro cedure is a course adjustment. If, when bolt A is tightened, the wheels still move slowly, the fine tuning will be done in step 9.

7. Loosen (4) jam nuts on neutralizing plate. Figure 18, and depress neutralizer pedal completely. Figure 3. The cam follower roller. Figure 18, should remain in line with the cam dwell center mark. Snug (4) jam nuts up against neutralizer plate. Release pedal and securely tighten jam nuts.

8. Check the hydrostatic control lever. If the neutralizer pedal does not automatically shift the control lever to the neutral position from either "forward" or "reverse" when the pedal is fully depressed, loosen hydrostatic control fork adjustment bolt D, Figure 19. Move the fork so that it aligns with the neutral slot in the control console. Securely tighten bolt D.

9. If the wheels still move slowly when neutralized, increase the engine speed to full throttle. Loosen clamp bolt B, Figure 18 and adjust the eccentric roller until the wheels stop completely. Tighten clamp bolt B, Figure 18.

CONTROL LEVER FRICTION ADJUSTMENT

The hydrostatic friction plates, shown in Figure 19, must

be adjusted so the control lever moves through the "forward" and "reverse" modes with a minimum of force. However, there must be sufficient spring pressure on the friction

plates so that, under normal operating conditions, the control

lever will remain at any selected setting.

If the tractor has a tendency to slow down or speed up

without touching the control lever, it will be necessary to in crease the spring pressure on the friction plates by tightening the screws at A and B, Figure 19. Access to these screws can be gained by raising the rear deck of the tractor and inserting a screw driver through the access holes as shown.

If the tractor has a tendency to speed up, tighten screw A

slightly more than screw B.

If the tractor has a tendency to slow down, tighten screw

B slightly more than screw A.

NOTE: The control console, see Figure 19, has been

removed for clarity only.

When the mechanism is properly adjusted, the park-lock pin will engage the teeth of the reduction gear when the control lever reaches Point B, Figure 21, and the pin will be completely disengaged at Point A.

Adjustment is made by loosening

nuts A, Figure 20, and moving the cable housing "in" or "out" until the over-center latch actuates when the control lever reaches Point C,

Figure 21, as the lever is moved

from the front of the slot, rear

Moving the cable housing "in" to

PARK LOCK MAINTENANCE AND ADJUSTMENT

When the hydrostatic control lever is placed in the "park-

start" position, the cable shown in Figure 20 is pushed out of the cable housing causing the pivot plate to rotate in the di rection of the arrow. This results in the park-lock pin engaging in a reduction gear in the differential housing which locks the

rear wheels. When the control lever is moved forward, the pivot plate rotates opposite to the direction of the arrow shown in Figure 20 and the park-lock pin disengages from the

reduction gear thus unlocking the rear wheels.

The park-lock mechanism should be kept clean of any dirt

or grass build-up and the moving parts should be oiled occasionally to assure that the park-lock functions properly.

The park-lock mechanism is properly adjusted when the

over-center latch pin, Figure 20 actuates at Point C, Figure

2fl (approximately 1/2 to 2/3 the length of the slot on the console cover), as the control lever is moved from the front

of the slot back into the park-start position. A distinct

"click" can be heard when the over-center latch actuates.

PARK LOCK BRAKE ADJUSTMENT

The park lock brake must be adjusted to hold the control

lever at the rear of the "park-start" slot in the console. Other wise, while starting the engine, the control lever will need to be held back to fully depress the safety switch located under the console cover.

The "park-lock" brake is adjusted by tightening or loosen

ing nut A, Figure 20;

FRONT WHEEL TOE-IN ADJUSTMENT

Proper toe-in of the front wheels is necessary to assure

proper steering and to reduce tire wear. The proper amount of toe-in is when the front of the wheels are 1/16" to 1/8" closer together than the rear of the wheels, measured at the

horizontal centerline of the rim flange.

-12-

tf the steering develops a wandering characteristic or if

excessive tire wear develops, the toe-in of the front wheels should be checked. If the toe-in is incorrect, adjust as follows:

1. Loosen jam nuts A and B,' Figure 23.

2. Rotate tie-rod until toe-in is correct. Shorten tie-rod to decrease toe-in. Lengthen it to increase toe-in.

3. Tighten jam nuts A and B after correct toe-in is obtained.

BRAKE ADJUSTMENT

The tractor brakes will require adjustment when the brake

pedal depresses over two inches. To adjust the brakes proceed as follows:

1. Block up the rear of the tractor with the wheels off the

ground.

2. Remove the wheel lug nuts and remove the wheel.

3. Insert a screw driver in the slot in the brake drum (See Figure 22) and tighten the star washer until the brakes are snug and the drum does not turn. Back off the star washer one full turn.

4. Replace the wheel and secure with the wheel lug nuts.

Repeat adjustment on the opposite wheel.

STEERING GEAR adjustment

If excessive looseness is noticed in the steering system after

continued use, the steering gear may require adjusting to re move excessive backlash between the gears. Adjust steering gear using the following procedure:

1. Raise front of tractor so that the tires clear the ground.

2. Remove cotter pm identified in Figure 23.

3. Loosen jam nut C, Figure 23 and turn adjusting screw out (counter-clockwise) 1V2 turns.

4. Tighten adjusting plug. Figure 23, to 10-14 ft. lbs. of torque.

5. Rotate adjusting plug out slightly to align nearest slot in the plug with the cotter pin hole and reinstall the cotter pin.

6. Hold jam nut and turn adjusting screw. Figure23,

clockwise (in) until backlash is removed from steering wheel. DO NOT FORCE ADJUSTING SCREW. Torque jam nuts 35-45 ft. lbs. while holding adjusting screw in position.

k 7. Turn steering wheel from lock to lock and check for ^binding or dragging inside gearbox. If any binding or

dragging exists, it will be necessary to loosen the adjusting screw and/or the adjusting plug slightly until steering wheel turns freely with no excessive looseness.

STEERING STOP ADJUSTMENT

When making a full right hand turn, the spindle arm should contact the axle stop as shown in Figure 24. When making a full left hand turn, the left spindle arm should contact the left axle stop. Proceed as follows to adjust the steering stops after checking toe-in.

1. Rotate front wheels to the right until right spindle arm

contacts the axle stop. Figure 24.

2. Remove drag link rod end from steering arm. Figure 24, and loosen jam nuts A.

2a. Rotate steering wheel clockwise until steering gear bottoms.

Back off 1/8-1/4 turn counter clockwise.

3. Rotate drag link as required while preventing the loose rod end from turning until the stud is approximately Vs hole to the rear of hole in steering arm. Figure24. Be sure axle stop contacts steering arm.

4. Reinstall rod end stud in steering arm and tighten jam

nuts A.

5. Rotate wheels completely to the left. The left spindle arm should contact left axle stop. If it does not, repeat step

2 and shorten drag links slightly until both spindle arms con

tact their respective axle stops when making full turns in either direction. The steering gear should not bottom before the spindle arm contacts the axle stop.
