There should be a small gap

Block up rear frame 3 inches. Line tractor up over the rear/main frames. Make sure DLOCK is open, clip pin is off and handle is stored.

Drive forward so that the front bracket pin is just behind the front hanger's hook. It should be lined up so you can drive into the front hanger when it is raised up. Hook up the hydraulics.

Raise the front hanger by extending the lift cylinders so the pin and hook are level.

Now close the lift cylinders. This will take the weight off the rear frame. Pry and jack up if necessary. Close the DLOCK.

Drive forward until the pin is in the front hanger.

Take clip pin off

Make sure Dlock is closed properly

To disengage: 1- RAISE THE BLADE 2- Open the Dlock 3- Extend lift cylinder to lower rear frame 4- Lower main frame to graund 5- Back out to clear front hanger 6- Unhook hydraulics

WARNINGIt is vital to raise the blade before opening Dlock.If you don't the rear frame will fall.

TORQUE

YOU ARE RESPONSIBLE . . . for your own safety and that of others. If you are not familiar with basic agriculture & industrial safety, you must get training. Owners of equipment must by law give operating instructions to other operators such as family members or a hired hand.

Making any design changes to equipment could cause a hazard and damage your machine.

Wear proper safety equipment.

Have handy:

• First aid kit • Fire extinguisher

Before working on machine:

• Turn tractor off • Set controls in neutral • Remove ignition key

Keep all parts clean. Replace worn or damaged parts.Don’t try any makeshift repairs. Before operating check that everything is tight and not broken.

Wear gloves and eye protection when searchingfor leaks. Use a piece of wood or cardboard butnot your hand. High pressure oil will penetrate your skin. If that happens you risk serious injury.

Lower blade to the ground when not in use. Keep clear of blade when tractor is running. Keep hands & feet away from under blade. Turn engine off when hooking up hydraulics and engaging DLOCK during mounting or dismounting.

Lift blade up then hold with safety chain.Make sure SMV sign & reflectors are clean.Use your hazard lights.

• Lube all points• Torque all hardware to correct setting• Check hardware torque & hydraulics after

the first 2 hrs & again after 10 hrs.

Before using for the first time

Check:

• If all points lubricated• All components attached securely• Condition of cutting edge• Depth shoe wear• Tractor’s Hydraulic oil reservoir• Condition of hoses, lines & fittings

Before using each time Cycle the cylinders several times to warm up system.Cold weather

Check torque on all hardware periodically. Check after first 2, 10, 40, then every 200 hours.

IMPORTANT

Bleed hydraulics of air. Cycle the hydraulics several times and hold the cylinders at full extent for several seconds.

Bleeding hydIf needed, balance out your tractor by ballasting the rear end. You may need to raise the tire pressure in the front wheels. Consult your tractor's manual.

Rear end weights & Tire inflation

Here are some the things you can do with your hyd system in float position;

• Skim the top of pavement• Run on the skid shoes• Back drag

Floatation mode

Why is SAFETY important to YOU?3 BIG Reasons:

•Accidents Can Disable and Kill•Accidents Are Costly•Accidents Can Be Avoided
