OPERATION

The designed and tested safety of this machine depends on it being operated within the limitations as explained in this manual. Be familiar with and follow all safety rules in the manual, on the cutter and on the tractor.

The safe operation of this cutter is the responsibility of the operator, who must be properly trained. The operator should be familiar with the equipment and all safety practices before starting operation. Read the safety information on page 7 through page 13.

Recommended tractor ground speed for most conditions is from 1 to 6 mph.

Always operate tractor PTO at 540 RPM, or at 1,000

RPM for Q models.

make contact with the ground or objects outside the machine. Do not leave the cab until the storm has passed.

 Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.

CONNECTING CUTTER TO TRACTOR

NOTICE

■

For tractors with a 1-3/8" diameter PTO shaft, the horizontal distance from the end of the tractor

PTO shaft to the center of drawbar pin should be

14" for the 540 RPM cutter and 16" for the 1000

RPM cutter. Tractors with 1-3/4 20-spline PTO shaft should be set to 20". This will minimize joint knock and damage to drive components.

 Look down and to the rear and make sure area is clear before operating in reverse.

 Full chain shielding must be installed at all times. Thrown objects could injure people or damage property.

• If the machine is not equipped with full chain shielding, operation must be stopped.

• This shielding is designed to reduce the risk of thrown objects. The mower deck and protective devices cannot prevent all objects from escaping the blade enclosure in every mowing condition. It is possible for objects to ricochet and escape, traveling as much as 300 feet (92 m).

 Never allow children or untrained persons to operate equipment.

 Do not allow bystanders in the area when operating, attaching, removing, assembling, or servicing equipment.

 Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.

 Stop power unit and equipment immediately upon striking an obstruction. Turn off engine, remove key, inspect, and repair any damage before resuming operation.

 Stay away from the machinery during a thunderstorm. If lightning from a thunderstorm strikes during operation, remain in the tractor cab. Do not

14 Operation

Figure 1 . Cutter to Tractor Connection

MAN1281 (4/15/2019)

1.

Check tongue clevis to make sure it is adjusted to match your tractor PTO speed.

2.

Position tongue clevis (A) up or down based on tractor drawbar height.

3.

Attach cutter using a 1-1/8" clevis pin (1) and clip.

4.

Attach safety tow chain (2) to drawbar support.

Leave enough slack for turning.

5.

Connect cutter driveline to tractor PTO shaft, making sure the spring-activated lock pin slides freely and is seated in tractor PTO splined groove.

6.

Remove parking jack (3) from the tongue and attach it to the storage post on the front of the left wing.

7.

Adjust nuts (4) so tongue clevis (A) is parallel with the tractor drawbar.

8.

Remove parking jack (3) from the tongue and attach it to the storage post on the front of the left wing.

NOTE: Place driveline in storage position on the hose holder (5) when not in use.

Hydraulic Connection

1.

Inspect hydraulic hoses to ensure they are in good condition.

2.

Clean the fittings before connecting them to the tractor hydraulic ports.

3.

Route the hose through the hose holder at the hitch and be sure the hose can slide freely in the holder. Do not allow hose slack to drag on the ground or become caught on tractor protrusions.

4.

Attach the hydraulic hose to the tractor.

5.

Raise unit with center lift cylinder and extend wing cylinders. Stop tractor and remove transport lock pins from wing stops and transport stop as shown in Figure 2 and Figure 3, page 17.

6.

From the operator position, start tractor and raise and lower deck several times to purge trapped air from the hydraulic cylinder.

Interference Check

1.

Be sure that tractor 3-point lift links do not interfere with hydraulic hoses, cutter driveline, or cutter frame.

2.

Check for straight-ahead operation and at full turning angles. If there is any interference, remove the lower lift links.

3.

Contact between tractor lift links and cutter parts can cause damage, especially when turning.

MAN1281 (4/15/2019)

CV Driveline Turning Limits

NOTICE

■ You must not exceed a turning angle of 80 degrees at the head of the Constant Velocity driveline or damage will occur.

1.

To check for potential excessive turn angle, disconnect the driveline from tractor.

2.

Start engine and turn as far right or left as possible.

3.

Shut engine off and try to connect CV driveline to tractor. If it cannot be connected, the turn angle is too severe.

4.

Restart engine and straighten angle slightly, shut off engine and try to connect CV driveline to tractor.

5.

Repeat the process until the driveline can be connected. The point at which the driveline can be connected is the maximum turn that should be made.

Cutting Height Adjustment

NOTICE

■

Avoid ground contact with blades. Striking ground with blades produces one of the most damaging shock loads a cutter can encounter. If this occurs repeatedly, the cutter, driveline, and gearboxes will be damaged.

Cutting height range is from 2" to 15". A hydraulic cylinder is used for cutting height adjustment.

When selecting a cutting height, you should consider the area of operation. If the ground is rolling and has mounds the blades could contact, set the cutting height accordingly. The cutting height (blade edge) is approximately 1" above the bottom of the side skid.

Cutting Height (Normal Mowing) - Center Section

1.

Position the cutter on a hard level surface and select an approximate cutting height, Example 6".

2.

Raise wings and lock them in the UP position.

3.

Use the hydraulic cylinder to raise or lower the center section to obtain a distance of 5" from bottom edge of skid shoe to the ground.

4.

Place jackstands under the four corners of the center section. See illustration on page 21. Lower center section to relieve pressure on attitude rod nuts.

5.

Loosen outer jam nut on the attitude rods.

6.

Adjust inner nuts in or out until the rear of the cutter is approximately 1/2" higher than the front. See

Figure 1A. It’s used as a starting point for adjusting the attitude rod, based on different tongue height and wheel options.
