Section 1 Setup and Operation Safety

_____________________________________________________________________________________ 7 FL72 Flail Mower 1/28/05

Section 1 Setup and Operation Safety Tractor Requirements This mower is designed with a patented category 1 3-Point hitch. The hitch allows the operator to maneuver around obstacles without damaging the turf. The FL-72 weighs approximately 1300lbs with the front roller attached.

Understanding How the Swing Hitch Operates (Prior to Hitching to Tractor) Push the swing mast rearward to disengage the swing lock. Grasp the hitch pins and rotate the “A” frame to simulate operation in a sharp turn. Release the hitch pins and slowly pull the swing mast forward as it would be pulled by the top link during lifting. Notice how one mast chain tightens causing the “A” frame and unit to realign and the spring on the lock link is compressed to make the swing lock engage upon alignment. Now push the swing mast rearward against the lock link tab to disengage the swing lock and loosen the chains to allow sharp turns again. This demonstrates how the top link of the tractor lift-system switches the mower between the trail and lift modes.

Tractor Hook-Up 1. Align lower link arms of tractor to hitch pins on

swing hitch. Insert these pins into the lower ball swivels and attach linch pins.

2. Attach tractor top link to swing mast on mower and secure with proper clevis and lock pins.

3. Adjust the tractor top link in or out to place the swing mast against the “A” frame. When the horizontal bar is level with the ground, the hitch is set properly. Refer to Figures 2 and 3.

Driveline Installation 1. Make sure you have correct driveline. 2. Slide driveline end with overrunning clutch over

splined shaft of gearbox and secure the spring loaded lock pin.

3. Slide other end of driveline over the tractor’s splined PTO shaft and secure spring loaded ball collar.

4. Vigorously move the driveline back and forth to ensure it is secure on the PTO shaft of the tractor and mower gearbox.

5. Attach the chain from the driveline shield the PTO Shield to ensure that the shield does not rotate. Supply just enough slack to allow the driveline to move slightly as the mower makes sharp turns.

CAUTION Tractor PTO shields and all mower guards must be in place at all times during operation.

Operation Safety • Your Safety Is Always First! Familiarize

yourself with the safety symbols and decals on pages 2 thru 5.

• All operators should read and understand all the provided sections of this manual prior to adjusting, maintaining, hitching to or operating the flail mower.

• Remove and read the driveline safety and maintenance manual taped to the driveline shield. After reading the driveline manual, place it inside this manual for reference.

• For a safety instruction of all operators, keep this manual stored on the mower at all times.

• Never attempt to adjust, maintain, or remove debris from any moving part of this machine while it is attached to a tractor or other power source with the engine running.

• After operating, always disengage the PTO and switch the engine off prior to dismounting from the tractor or other power source and approaching the unit.

• Prior to starting, always inspect operating area for any hazards such as large rocks, steep slopes, low tree branches or wires. Flag objects difficult to see such as irrigation heads and water meters.

• Instruct all people in the work area to stay clear of the operating unit at least 10 feet on the sides and 30 feet on the rear.

• Consult your tractor Operator’s manual regarding operation on slopes. Do not lift the unit while the tractor is moving (or parked) sideways on slopes above 50. The swing hitch may allow the unit to swing to the downhill side and cause the tractor to roll over. On slopes from 50 to 150, always aim the tractor uphill before lifting the unit. We do not recommend the unit being used on slopes above 150.

• Use extreme care and maintain moderate ground speed when transporting or operating on slopes, over rough surfaces, or close to trees, ditches, and fences.

• Only operate during daylight hours or with good artificial light.

• The FL-72 is not equipped for highway use. Be careful of traffic when operating near or crossing roads.

• Before hitching to the mower, familiarize yourself with all of the tractors control functions. Be prepared to stop the tractor’s movement, PTO operation, and the engine quickly in an emergency.

Section 2 Operating Instruction

_____________________________________________________________________________________ 9 FL72 Flail Mower 1/28/05

Section 2 Operating Instruction Transporting 1. Always disengage PTO before raising the

mower to transport position. 2. Be sure to reduce tractor ground speed when

turning, leaving enough clearance so the mower does not contact obstacles such as buildings, trees, or fences.

3. Select a safe ground travel speed when transporting from one area to another. When traveling on roadways, transport in such a way that faster moving vehicles may pass safely.

4. When traveling over rough or hilly terrain, shift tractor to a lower gear.

5. When driving or backing a tractor and mower up or down load ramps, always shorten the top link to lift the rear of the mower as high as possible.

Mowing Instructions 1. Grass is best cut when it is dry. Mowing wet

grass can cause plugging resulting in grass clumps behind the mower.

2. Grass should be mowed frequently as shorter clippings deteriorate faster.

3. When mowing extremely tall grass, it is best to raise cutting height and mow the area, then lower cutting height and mow a second time at the desired height.

4. When mowing in sandy soil areas, wear may occur to the mower knives from sand erosion. Frequently inspect knives and replace if damaged.

5. Clear the area to be mowed of objects and debris that might be picked up and thrown by the mower blades.

Operating Instructions Proper servicing and adjustments are the keys to a long life of any machine. With careful and systematic inspection of the mower, costly maintenance, time, and repair can be avoided. Before beginning to mow, the following inspection should be performed:

1. Check oil level in gearbox. Refer to “Section 4 Maintenance and Lubrication”.

2. Check that all plugs in gearbox have been replaced and tightened properly.

3. Be sure all mower bolts and nuts are tight. 4. Be certain all guards and shields are in place

and secure. 5. Grease driveline shaft and all other grease

fittings. 6. Clear the area to be mowed of rocks, branches,

and other foreign objects. 7. Lower mower to ground. Set tractor throttle to

approximately ¼ open. Engage PTO to start blades rotating.

8. Operate with 540 rpm PTO tractor! 9. When lowering for operation, lower slowly until

rear roller slightly touches ground. Then swiftly lower the mower completely to unlock the hitch. This is especially true when lowering the unit in a sharp turn. Failure to do this may cause the swing hitch not to disengage, resulting in damage to the mower. Do not turn the tractor with the swing lock engaged and the mower on the ground!

10. At first, begin mowing at a slow forward speed and shift up until the desired speed is achieved – maintaining 540 PTO rpm.

11 After mowing the first 50 feet, stop and check to see that the mower is adjusted properly.

12. Do not back the unit up with the mower touching the ground. Always raise the unit, back to desired location, and then lower the machine.

13. Do not engage PTO with mower in the fully raised position.

14. Do not engage PTO with tractor at full throttle.

Section 3 Adjustments

_____________________________________________________________________________________ 1/28/05 FL72 Flail Mower 10

Section 3 Adjustments Cutting Height The cutting height of the mower depends primarily on the position of the rear roller. Refer to Figure 4. 1. Adjust turnbuckles until the rear roller is

completely raised. This ensures that the turnbuckles start at the same location (0” cutting height for new blades).

2. Gradually rotate turnbuckles until desired height is reached. One complete turn of the turnbuckle is about 1/5”; therefore, 5 complete turns will yield one approximately 1” of cut with new blades. It is only recommended that each side of the machine be adjusted 1” above the other before the opposite must be raised to level; otherwise, the turnbuckles may bind.

3. Snug the jam nut on the turnbuckle to help hold the cutting height during operation.

4. Slowly mow a small strip to check for adjustments and verify proper cutting height and that mower is cutting level.

5. If cutting height is unsatisfactory or uneven, make proper adjustments to turnbuckles and repeat step 4.

CAUTION Engage parking brake, shut off tractor, remove key, and disengage PTO before making any adjustments!

3-Point Hitch The patented 3-point hitch is design to enhance the maneuverability of the mower by giving it the capability of cutting a 4-foot radius without harming the turf. However, proper adjustments must be made in order to avoid potential problems. In addition to this, hitch adjustment can affect the cutting height. Since tractors vary, be mindful of readjusting the hitch when changing from one tractor to another. 1. After slowly cutting a small strip, check to see if

the horizontal bar is level with the ground (see Figure 3). If the hitch is nosed down, adjust the top link of the tractor to correct its position.

2. Check to see if there is proper clearance between the driveline and the bottom of the hitch. Different tractors have varying geometries; therefore, some tractors require special attention concerning driveline clearance.

Scalping In certain situations, it is desirable to cut the turf very close to the soil (scalping). This procedure calls for an adjustment to the hitch and front roller. 1. The hitch must be “locked out”, meaning that

the mast chains must be taken up to lock the hitch in place and prevent it from turning. Refer to Figure 5.

2. Raise rear roller as high as possible and lock into place using the provided jam nuts.

3. Slowly mow a short strip and check the following: horizontal bar is level with ground (see Figure 3); mower is cutting level. If necessary, adjust tractor top link to level the bar and adjust turnbuckles to level cut (see Figure 4). It is preferred that the horizontal bar be level if not slightly tilted upward toward the front.

5. Lower the front roller using the attached turnbuckles until it lightly touches the ground. Lock it into place using the provided jam nuts.

CAUTION Do not turn mower while hitch is locked! Turning in the locked position with the mower on the ground can cause serious damage to the mower.

Belt Tension The belt tension should be checked after the first 20 hours of use and then every 40 hours thereafter. To check tension, apply approximately 25 pounds of pressure half way between the pulleys. There should be about 3/8” of deflection. If there is excessive belt deflection, then the belts need tightening.

Belt Tightening Refer to Figure 6 during these steps.

1. Loosen the four flange nuts located under the jackshaft shield.

2. Rotate the 5/8” nut to tighten the belts to the desired tension.

3. Retighten the four flange nuts and secure all shields and guards back in place before operation.

WARNING Excessive tension on the belt may lead to premature failure of belt and drive components. Excessive tension on the belt may also lead to a safety hazard to the operator or bystanders.

Section 4 Maintenance and Lubrication

_____________________________________________________________________________________ 1/28/05 FL72 Flail Mower 12

Section 4 Maintenance and Lubrication Maintenance Proper servicing and adjustment is the key to the long life of any implement. With careful and systematic inspection, costly maintenance, time, and repair can be avoided.

CAUTION For safety reasons, each maintenance operation must be performed with tractor PTO disengaged, the mower lowered completely to the ground and the tractor engine shut off with ignition key removed.

• After using the mower for several hours, check all bolts to be sure they are tight and check the tension of the drive belt. Refer to Belt Tension on page 11.

• Lubricate items as listed under Lubrication starting on page 13.

• Replace any worn, damaged or illegible safety labels by obtaining new decals from your local First Products Dealer. Information safety decals are located under Safety Decals starting on page 3.

Service Mowing Knives IMPORTANT: Make sure that each knife is the same length as the others on the mower. This will keep the cut smooth and cutting drum dynamically balanced. Always use First Products knives to replace worn ones. 1. Unbolt retaining rods. 2. Pull each retaining rod out through the hole

provided in the side of the endplate. Refer to Figure 7.

3. Examine retaining rods, d-rings, and oval rings for wear, and replace if necessary. Remember, retaining rods can be rotated to provide extra life; however, if the grooves worn into retaining rods reduce its diameter to less than 3/8”, replace immediately.

4. Reassemble the knives on the oval and d-rings and hold them in the grooves while a partner slides the retaining rod back through the end plate. Make sure the knives are facing the right direction. The cutting drum rotates over the top and forward.

5. Use new hardware to bolt the retaining rods back in place. Use the parts list to order the proper parts.

WARNING Top-Lock Nuts are used to fasten the retaining rods. Standard nuts stand a greater risk of backing off causing serious danger to the operator and bystanders.

V-Belt Installation Refer to Belt Tension under Section 3 Adjustments for proper belt tension. Refer to Figure 6 for visual assistance. 1. Remove belt cover and lift driveline shield. 2. Loosen the four flange nuts under the driveline

shield. 3. Rotate 5/8” nut on push rod to lower top pulley. 4. Remove old belts and install new. 5. Rotate 5/8” nut to raise top pulley to desired

tension. 6. Tighten the four flange nuts under the driveline

shield. 7. Secure Belt cover and driveline shield before

operation.
