Numbers are located on the product registration form in the unit literature package. They are printed on a serial number label, located on the frame of your unit.
Figure 1
1.3 PRODUCT REGISTRATION
A warranty registration card must be filled out, signed, and returned at time of purchase. This card activates the warranty. Claims meeting requirements during limited warranty period will be honored.
1.4 UNAUTHORIZED REPLACEMENT PARTS
Use only Gravely replacement parts. The replacement of any part on this vehicle with anything other than a Gravely authorized replacement part may adversely affect the performance, durability, or safety of this unit and may void the warranty. Gravely disclaims liability for any claims or damages, whether warranty, property damage, personal injury, or death arising out of the use of unauthorized replacement parts.
1.5 DISCLAIMER
Gravely reserves the right to discontinue, make changes to, and add improvements upon its products at any time without public notice or obligation. The descriptions and specifications contained in this manual were in effect at printing. Equipment described within this manual may be optional. Some illustrations may not be applicable to your unit.
1.6 TECHNICAL SERVICE COMMUNICATIONS
Ariens Technical Service communicates information to the field using Service Letters, Service Bulletins, Product Notices, and Campaigns. Each communication signifies a type of information and priority. The dealer is responsible to carry out the directive provided in the communication. The types of communication are:
Service Letter - General technical information for the dealer. Technical information on how to service the product and product improvements.
Service Bulletin - Notification to update products to resolve certain issues or a notification of a policy change.
Product Notices - Notification of limited product located in a certain region. This is a limited distribution to only those who received the product involved.
Campaigns - Notification of a safety related issue. All products must be updated and are tracked by the factory until all units are corrected.
1.7 PREPARATION
Before starting any removal of parts, proper preparation is very important for efficient work. A clean work area at the start of each job will allow you to perform service repairs easily and quickly.
1 - 3
To reduce the incidence of misplaced tools or parts, place removed components with all attaching hardware in the disassembly order on a clean work surface. Organization is a key part of proper reassembly.
Tools, instruments, and parts needed for the job should be gathered before work is started. Interrupting a job to locate tools or parts is a needless delay.

4.5 CLEANING AND STORAGE
WARNING: AVOID SHARP EDGES which can cut. Movement of parts can cut off fingers or a hand. Wrap blades, wear gloves, and use extreme caution when servicing.
IMPORTANT: Never spray unit with water or store unit outdoors to help prevent sealed bearing rust or corrosion. Water can seep into sealed bearings and reduce component life. Bearings are sealed against dirt and debris only.
A unit that is excessively dirty should be cleaned before work starts. Cleaning will occasionally uncover trouble sources. Dirt and abrasive dust reduce the efficient work life of parts and can lead to costly replacement.
4 - 9
When taking unit out of extended storage:
1.Check for any damage or loose parts. Repair, replace, or tighten hardware before operation, especially blade attachment bolts.
2.If a preservative fluid was used in fuel tank, drain and discard. Fill fuel tank with fresh new fuel.
4.6 FILLING THE FUEL TANK
EXPLOSIVE VAPORS and FLAMMABLE FUEL can result in serious injury or death. Handle fuel with care. ALWAYS use an approved fuel container.
No Smoking!
No Lighted Materials!
No Open Flame!
Allow engine to cool.
Use caution with fuel. Fuel is very flammable. Keep fuel in a clean and tight container. Keep fuel away from fire or heat. Never put fuel in the fuel tank while the engine is running or hot. Clean up any spilled fuel before starting the engine.
Add fuel to the tank as needed. See your Engine Manual for correct type and grade of fuel.
To add fuel to the fuel tank:
1.Refuel the unit only in a well ventilated, open area.
2.Stop the engine.
3.Clean the fuel cap and the area around the fuel cap to prevent dirt from entering the fuel tank. Remove the cap from the fuel tank.
4.Fill the fuel tank. Be careful not to spill the fuel. Do not overfill, allow for fuel expansion. Stop filling when fuel is about 1” below the bottom of the neck.
5.Install the cap on the fuel tank and tighten.
6.Clean up any spilled fuel before starting the engine.
WARNING: POTENTIAL HAZARDOUS! Fuel is extremely flammable and highly explosive. Personal injury and property damage may result if not handled properly.
•Fill the fuel tank outdoors in an open area. Do not fill when the engine is hot. Wipe up any fuel spills.
•Never fill the fuel tank completely full. Empty space in tank allows fuel to expand.
•Never smoke when handling fuel. Stay away from open flames. Fuel fumes can be ignited by sparks.
4.7 FASTENERS
Each day before operating, check mower blade mounting hardware and all other fasteners. Replace fasteners that are missing or damaged. Tighten all nuts and bolts to their correct torque value.
4.8 GENERAL LUBRICATION
IMPORTANT: Wipe each fitting clean before and after lubrication.
Lube fitting locations are:
-each deck push arm (2)
-Hydro Idler (1)
-front axle pivot (1)
Apply Sten Mix Hi-Temp Grease or equivalent to the lube fittings. Order P/N: 00036700ten pack of 14 oz. cartridges.
When using Sten Mix Hi-Temp Grease for the first time, all components should be thoroughly cleaned prior to lubricating.
Apply oil at all pivot points and pin connections.

4.9 BASIC ENGINE MAINTENANCE
See your engine manual and Section 5 of this manual for detailed information on the operation and maintenance of your engine.
1.Each day before operating, check the level of the oil in the engine. Never operate the engine when the oil level is below the add mark.
2.Each day before operating, check the air cleaner element. Dirt can decrease the flow of air to the engine.
3.Each day before operating, check the air cooling system on the engine. Debris can decrease the flow of air cooling the engine.
4.Follow the maintenance instructions in your engine manual concerning oil and filter changes.
4.10 BELTS
WARNING: MOVING PARTS can cut or amputate body parts. ALWAYS wait for moving parts to stop before performing maintenance or service.
CAUTION: DAMAGED OR WORN BELTS may result in injury and/or damage to the unit. Check belts for excessive wear or cracks often.
Belt Access
1.Properly stop and park unit (refer to Owner’s Manual).
2.Lower the mower.
3.Place seat in most rearward position.
4.Remove belt covers.
5.Place foot board in open position (Figure 6).
6.Secure raised footboard with latch.
Replacing Mower Belts
NOTE: Long belt must be removed to remove short belt.
1.Roll long belt off left blade spindle and remove from deck.
2.Roll short belt off right blade spindle and remove from deck. Idler pivot bolt must be loosened slightly to gain clearance to remove belt from under idler pulley (Figure 7).
CAUTION: Use care when releasing idler spring tension. Keep body parts well away from idlers when performing this operation.
3.Arrange new mower belt(s) on deck (short belt first). Retighten short belt idler pivot bolt. Install belts on sheaves. Roll belts onto blade sheave last.
4.Replace belt covers and return foot board to closed position.
Replacing the Hydro Pump Belt
1.Properly stop and park unit (refer to unit Owner’s Manual).
2.Remove the mower belt from the mower clutch sheave. See Replacing Mower Belts.
3.Remove old hydro pump belt by rolling belt off right hand hydrostat sheave first (Figure 8).
4.Install new pump belt by positioning belt on sheaves. Roll belt onto right hand hydrostat sheave last.
5.Put the mower belt back on mower clutch sheave. See Replacing Mower Belts.
