Operating

Daily Operating Checklist

o Check for loose or missing hardware.

o Make sure all connections are tight.

o Make sure attachment responds properly to controls.

o Check for debris build-up that could obstruct proper motion of the blade trip components.

Raising and Lowering Blade


IMPORTANT: Avoid damage! A “clicking” or “ratcheting” sound when blade is fully raised or lowered indicates actuator clutch slippage. To prevent unnecessary wear or damage, keep clutch slippage to a minimum. Release switch if actuator slippage occurs.

MX6747

NOTE: Key switch must be in RUN position for blade switch to function.

Raising Blade

1. Press and hold top (A) of switch to raise blade to desired height.

2. Release switch.

Lowering Blade

1. Press and hold bottom (B) of switch to lower blade to desired height.

2. Release switch.

Transporting Blade

Avoid contact with objects such as trees or fences. Be aware of blade end position while transporting. Blade makes a wide arc when turning.

Transport with blade raised to the highest position. Do not exceed 8 km/hr (5 mph).

Setting Blade Angle

c CAUTION: Avoid injury! Crushing injury can occur if blade drops unexpectedly. Keep hands and feet from under raised blade.

1. Raise blade slightly off ground.

2. Park machine safely. (See Parking Safely in the SAFETY section.)

3. Adjust blade angle.

Straight Blade

MX30835

a. Push down lever (A).

b. Swing blade to right or left position.

c. Release lever and make sure it locks into right position notch (B) or left position notch (C).

V-Blade

MX38598

• Install pins and spring locking pins (D) into holes for desired blade angle:


Holes	Blade Position	Usage
E-J	V	Push material to both sides
F-I	Straight	Push material forward
G-H	Scoop	Guide material forward
E-H	Angled Left	Push material left only
G-J	Angled Right	Push material right only

Adjusting Skid Shoes

c CAUTION: Avoid injury! Crushing injury can occur if blade drops unexpectedly. Keep hands and feet from under raised blade.

1. Raise blade slightly off ground.

2. Park machine safely. (See Parking Safely in the SAFETY section.)

MX30837

3. Remove lock pin (A).

4. Remove or add washers (B) and/or spacers (C) to attain desired ground clearance.

5. Lower blade to ground and check adjustment.

Setting Blade Tilt

c CAUTION: Avoid injury! Crushing injury can occur if blade drops unexpectedly. Keep hands and feet from under raised blade.

1. Raise blade slightly off ground.

2. Park machine safely. (See Parking Safely in the SAFETY section.)

MX39596

Picture Note: Blade stop setting on straight blade shown in perpendicular blade position.

3. Loosen locknut (A) on each eyebolt to reduce spring tension.

4. Loosen bolt (B) on both sides of blade frame.

NOTE: The blade stops can be rotated to allow four possible blade tilt positions. Perpendicular blade position is recommended for best performance. Both stops must be adjusted to the same position.

5. Rotate blade stop (C) on both sides to desired tilt position.

6. Tighten bolts to 41 N•m (30 lb-ft).

NOTE: Spring trip must be adjusted each time blade tilt is changed.

7. Adjust the blade spring trip.

Adjusting Spring Trip

Straight Blade


IMPORTANT: Avoid damage! The spring trip feature is designed to protect blade and vehicle from severe impact. Do not over-tighten the springs. Spring trip should be adjusted to provide enough tension to keep blade against stops (A) when pushing light materials on a hard surface.

MX39596

Picture Note: Blade stop setting on straight blade shown in perpendicular blade position.

1. Adjust to initial setting by tightening locknuts (B) on eyebolts so 15 mm (9/16 in.) of thread is exposed. Tighten top nut (C).

2. Operate blade to determine if spring tension is sufficient for the type of material and terrain conditions.

3. Adjust spring trip if needed:

• Tighten locknuts (B) equal amounts to increase tension.

• Loosen locknuts (B) equal amounts to decrease tension.

4. Tighten top locknut (C) to secure eyebolt position.

V-Blade

MX39597

1. Adjust to initial setting by tightening three locknuts (A) on eyebolts so 15 mm (9/16 in.) of thread is exposed.

2. Operate blade to determine if spring tension is sufficient for the type of material and terrain conditions.

3. Adjust spring trip if needed:

• Tighten locknuts (A) equal amounts to increase tension.

• Loosen locknuts (A) equal amounts to decrease tension.

Checking Blade for Obstructions

1. Lower blade to ground.

2. Park vehicle safely. (See Parking Safely in the Safety section.)

c CAUTION: Avoid injury! Fingers and hands can be pinched or crushed. Be aware of potential pinch points and keep hands away.

MX6757

3. Check for obstructions around the springs and between the blade and blade frame. Use a long pry bar to remove obstructions.
