16 4 OPERATION 4.6 TO DRIVE / TRANSPORT Read and follow all safety notes contained in this manual when driving or transporting mower. Refer to Section 4.3 for general operating instructions. When operating in reverse, look behind you to ensure you have a clear path. Important: If this mower is driven on public roads, it must comply with federal, state, and local ordinances. Contact local authorities for regulations and equipment requirements. 1. Disengage all drives and raise implements to the transport position when driving to and from the area of operation. 2. Disengage parking brake and move throttle lever to FAST. Depress traction pedal slowly. CAUTION To prevent tipping or loss of control, travel at reduced speed when making turns. 4.7 HILLSIDE OPERATION WARNING To minimize the possibility of overturning, the safest method for operating on hills and terraces is to travel up and down the face of the slope (vertically), not across the face (horizontally). Avoid unnecessary turns, travel at reduced speeds, and stay alert for hidden hazards and drop offs. CAUTION Do not operate this mower on slopes greater than 20. The mower has been designed for good traction and stability under normal mowing conditions; however, use caution when operating on slopes, especially over rough terrain, or when the grass is wet. Wet grass reduces traction and steering control. 1. Always mow with the engine at full throttle but reduce forward speed to maintain the proper cutting frequency. 2. If the mower tends to slide or the tires begin to mark the turf, angle mower into a less steep grade until traction is regained or tire marking stops. 3. If mower continues to slide or mark the turf, the grade is too steep for safe operation. Do not make another attempt to climb, and back down slowly. 4. When descending a steep slope, always lower implements to the ground to reduce the risk of mower overturning. Correct tire pressure is essential for maximum traction. Front and Rear psi (69-83 kpa). 16

17 OPERATION MOWING NOTICE WARNING To prevent serious injuries, keep hands, feet, and clothing away from cutting unit when the blades are moving. NEVER use your hands to clean cutting units. Use a brush to remove grass clippings from blades. Blades can be sharp and could cause injuries. To clear obstructions from cutting unit, disengage reel switch, engage parking brake, stop engine, and remove key from ignition switch; then remove obstruction. To mow: 1. Start the engine and lower the mowers to the ground. 2. Turn reel switch to ON and disengage parking brake. To prevent damage to the reel and bedknife, never operate reels when they are not cutting grass. 3. Move throttle lever to FAST then slowly depress traction pedal to the desired mowing speed. a. For complete even cutting, overlap swaths by a few inches. b. Stop and raise the mowers to the transport position when crossing paths or roadways. Look out for traffic. 4. To remove or install the grass catchers, lower the cutting units to the ground, engage the parking brake, and shut off the engine. Tilt the grass catcher body so the front edge clears the mower frame, and slide the catcher onto or off of the catcher frame. 4.9 TOWING / TRAILERING If the mower experiences problems and must be shut down and removed from the area, it should be loaded onto a trailer for transport. If a trailer is not available, the unit can be towed slowly short distances. Use care when loading and unloading mower. Fasten mower to trailer to prevent mower from rolling or shifting during transport. Before towing, open tow valve. The tow valve permits moving the mower without starting the engine and prevents possible damage to hydraulic components. The tow valve (A) is located on the bottom of the drive pump under the mower. To open valve, loosen jam nut on valve stem and turn valve counterclockwise. Long Distance Trailering / Transport. If the mower is to be trailered on the highway, before strapping to trailer, inflate tires to: Front - 18 psi (124 kpa) Rear - 24 psi (165 kpa) After unloading mower, reduce tire pressure to normal operating pressure. See Section 4.7 A Before towing make sure cutting units are raised. If they cannot be raised, remove them from the mower. Close valve completely and lock in place with jam nut after towing. NOTICE Do not exceed 2 MPH (3.2 KPH) while towing. Long distance towing is not recommended. Figure 4B 17

18 4 OPERATION 4.10 DAILY MAINTENANCE Important: For more detailed maintenance information, adjustments, and maintenance/lubrication charts, see the Parts & Maintenance manual. 1. Park the mower on a flat, level surface. Fully lower the implements to the ground, engage parking brake, stop the engine, and remove key from ignition switch. 2. Grease and lubricate all points if required. To prevent fires, wash the cutting units and mower after each use. a. Use only fresh water for cleaning your equipment. NOTICE Use of salt water or effluent water has been known to encourage rust and corrosion of metal parts resulting in premature deterioration or failure. Damage of this nature is not covered by the factory warranty. b. Do not use high pressure spray. c. Do not spray water directly at the instrument panel, or any electrical components. d. Do not spray water into the cooling air intake or the engine air intake. NOTICE Do not wash a hot or running engine. Use compressed air to clean the mower, engine, and radiator fins to reduce the potential for corrosion and moisture contamination. FUEL Fill mower s fuel tank at the end of each operating day to full mark on fuel gauge. Always use clean, fresh, #2 low or ultra low sulfur diesel fuel. Minimum Cetane Rating 45. Handle fuel with care - it is highly flammable. Use an approved container; the spout must fit inside the fuel filler neck. Avoid using cans and funnels to transfer fuel. WARNING Never remove the fuel cap from the fuel tank, or add fuel, when the engine is running or while the engine is hot. Do not smoke when handling fuel. Never fill or drain the fuel tank indoors. Do not spill fuel. Clean spilled fuel immediately. Never handle or store fuel containers near an open flame or any device that may create sparks and ignite the fuel or fuel vapors. Be sure to reinstall and tighten fuel cap securely. Store fuel according to local, state, or federal ordinances and recommendations from your fuel supplier. Never overfill or allow the tank to become empty. HYDRAULIC HOSE, OIL, AND FILTER WARNING To prevent serious injury from hot, high pressure oil, never use your hands to check for oil leaks; use paper or cardboard. Hydraulic fluid escaping under pressure can have sufficient force to penetrate skin. If fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. 1. Inspect hydraulic hoses and tubes daily. Look for wet hoses or oil spots and replace worn or damaged hoses and tubes before operating the machine. 2. Check the engine oil and hydraulic oil at the start of each day, before starting the engine. If the oil level is low, remove the oil filler cap, and add oil as required. Do not overfill. 18

19 QUALITY OF CUT 5 5 OF CUT 5.1 QUALITY OF CUT TROUBLESHOOTING It is recommended that a test cut be performed to evaluate the mower s performance before beginning repairs. An area should be available where test cuts can be made. This area should provide known and consistent turf conditions to allow accurate evaluation of the mower s performance. Another test cut should be performed after the completion of the repairs and/or adjustments to verify the mower s performance. Before performing a test cut to diagnose cut appearance and mower performance, the following items should be verified to ensure an accurate test cut. 1. Mowing (Ground) Speed. 2. Reel Bearing Condition and Pre-Load (End Play) Adjustment. 3. Reel and Bedknife Sharpness. 4. Bedknife Alignment to Reel. 5. Reel-to-Bedknife Contact. 6. Height-of-Cut (HOC). 7. Roller and Roller Bearing Condition. 5.2 WASHBOARDING Washboarding is a cyclical pattern of varying cutting heights, resulting in a wave-like cut appearance. In most cases, the wave tip-to-tip distance is approximately 6 8 in. (15 20 cm). Color variation (light-to-dark) may also be noticed. This condition is usually caused by a rocking motion in the cutting unit(s). This condition is found mostly on mowers with multiple (suspended) cutting units, but other causes can produce the same result. Washboarding may also be caused by variations in the turf. NOTE: Arrow indicates direction of travel. TN0159 Probable Cause Mowing (ground) speed is too fast. Grass build-up on roller. Roller is out of round. Mowing in the same direction. Use of a groomer on cleanup pass. Remedy Reduce mowing (ground) speed. Clean the roller and use scrapers or brushes. Replace roller. Change mowing direction regularly. Groomers should be used only in a straight line. 19

20 5 QUALITY OF CUT 5.3 MARCELLING Marcelling, like washboarding, is a cyclical pattern of varying cutting heights, resulting in a wave-like cut appearance. In most cases, the wave tip-to-tip distance is 2 in. (5 cm) or less. NOTE: Arrow indicates direction of travel. TN0220 Probable Cause Mowing (ground) speed is too fast. HOC (height-of-cut) setting is too low for turf conditions. Cutting reel diameter is worn. Remedy Reduce mowing (ground) speed. Check/adjust HOC to turf conditions. Check cutting reel diameter and replace if worn. 20

21 QUALITY OF CUT STEP CUTTING Step cutting occurs when grass is cut taller on one side of a reel than the other or one cutting unit to another. This is usually caused by mechanical wear or an incorrect roller or HOC (height-of-cut) adjustment. NOTE: Arrow indicates direction of travel. TN0221 Probable Cause HOC (height-of-cut) settings are different from one side of a reel to the other or from one cutting unit to another. Worn front roller bearings. Reel-to-bedknife contact is different from one side of the cutting unit to the other or from one cutting unit to another. Cutting reel movement is restricted. Variations in turf density. Machine weight distribution is uneven. Remedy Check HOC adjustment of cutting units. Check/replace front roller bearings. Check reel-to-bedknife contact. Check/remove cutting reel movement obstruction. Change mowing direction. Check/adjust tire inflation pressure. 21

22 5 QUALITY OF CUT 5.5 SCALPING Scalping is a condition in which areas of grass are cut noticeably shorter than the surrounding areas, resulting in a light green or even brown patch. This is usually caused by an excessively low height-of-cut (HOC) setting and/or uneven turf. NOTE: Arrow indicates direction of travel. TN0222 Probable Cause HOC (height-of-cut) settings are lower than normal. Improper reel-to-bedknife adjustment. Turf too uneven for the mower to follow. Cutting too much grass at one time. Mowing (ground) speed is too fast. Remedy Check/adjust the HOC settings. Adjust reel-to-bedknife setting for desired HOC. Change mowing direction. Mow more often. Reduce mowing (ground) speed. 22

23 QUALITY OF CUT STRAGGLERS Stragglers are scattered blades of uncut or poorly cut grass. NOTE: Arrow indicates direction of travel. TN0223 Probable Cause Bedknife improperly adjusted. Dull reel or bedknife cutting edges. Mowing (ground) speed is too fast. Grass is too tall. Mowing in the same direction. Nicks in reel or bedknife. Remedy Adjust reel-to-bedknife setting. Sharpen or replace reel blade and bedknife as necessary. Reduce mowing (ground) speed. Mow more often. Change mowing direction regularly. Grind, sharpen or replace reel blades and bedknife as necessary. 23

24 5 QUALITY OF CUT 5.7 STREAKS A streak is a line of uncut grass. This is usually caused by a nicked or bent bedknife. NOTE: Arrow indicates direction of travel. TN0224 Probable Cause Remedy Damaged bedknife. Damaged or unevenly worn reel. Loose or missing bedknife fasteners. Turning too aggressively. Cutting units don t overlap around turns or on side hills. Tire mats down grass before it is cut. Wet grass is matted down before it is cut. Replace bedknife. Inspect reel. Replace as needed. Check bedknife screws. Tighten loose screws; replace missing screws. Turn less aggressively to allow cutting units to overlap. Change mowing direction or pattern on side hills. Check/adjust tire inflation pressure. Mow when grass is dry. 24

25 QUALITY OF CUT WINDROWING Windrowing is the deposit of clippings concentrated at one end of cutting unit(s) or between two cutting units, forming a line in the direction of travel. NOTE: Arrow indicates direction of travel. TN0225 Probable Cause Remedy Grass is too tall. Mowing while grass is wet. Grass built up on roller(s). Grass collecting on bedknife. Mow more often. Mow when grass is dry. Clean roller(s) and scraper(s). Adjust reel-to-bedknife setting. 25

26 5 QUALITY OF CUT 5.9 RIFLING OR TRAMLINING Rifling or tramlining is a pattern of varying cutting heights, resulting in a wave-like cut appearance, usually due to heavy contact points across a reel and/or bedknife. NOTE: Arrow indicates direction of travel. Probable Cause Reel and/or bedknife unevenly worn. Missing, loose, or overtorqued bedknife screws. Mowing (ground) speed is too fast. Remedy Inspect bedknife and reel. Sharpen or replace reel and bedknife as necessary. Install, replace or tighten bedknife screws to proper torque setting. Reduce mowing (ground) speed MISMATCHED CUTTING UNITS Mismatched cutting units is a pattern of varying cutting heights, resulting in a stepped cut appearance, usually due to mismatched HOC (height-of-cut) adjustment from one cutting unit to another. NOTE: Arrow indicates direction of travel. Probable Cause HOC inconsistent from one cutting unit to another. Difference in mower ride height side to side. Remedy Check/adjust HOC on cutting units. Check/adjust tire inflation pressure. 26
