Keep ROPS Installed Properly

TS212-UN: Roll-Over Protective Structure

Make certain all parts are reinstalled correctly if the roll-over protective structure (ROPS) is loosened or removed for any reason. Tighten mounting bolts to proper torque.

The protection offered by ROPS will be impaired if ROPS is subjected to structural damage, is involved in an overturn incident, or is in any way altered by welding, bending, drilling, or cutting. A damaged ROPS should be replaced, not reused.

The seat is part of the ROPS safety zone. Replace only with John Deere seat approved for your tractor.

Any alteration of the ROPS must be approved by the manufacturer.

DX,ROPS3-19-20111012

Use Foldable ROPS and Seat Belt Avoid crushing injury or death during rollover.

Properly If this machine is equipped with a foldable rollover

protective structure (ROPS), keep the ROPS in the fully extended and locked position. USE a seat belt when you operate with a ROPS in the fully extended position.

Hold the latch and pull the seat belt across the body.

Insert the latch into the buckle. Listen for a click.

Tug on the seat belt to make sure that the belt is securely fastened.

Snug the seat belt across the hips.

If this machine is operated with the ROPS folded (for example, to enter a low building), drive with extreme caution. DO NOT USE a seat belt with the ROPS folded.

Return the ROPS to the raised, fully extended position as soon as the machine is operated under normal conditions.

Safety Entanglement in rotating driveline can cause serious injury or death.

Stay Clear of Rotating Drivelines

Keep tractor master shield and driveline shields in place at all times. Make sure rotating shields turn freely.

Only use power take-off driveshafts with adequate guards and shields.

Wear close fitting clothing. Stop the engine and be sure that PTO driveline is stopped before making adjustments, connections, or cleaning out PTO driven equipment.

Do not install any adapter device between the tractor and the primary implement PTO driveshaft that will allow a 1000 rpm tractorshafttopowera540rpmimplementatspeedshigherthan 540 rpm.

The angle at which the primary implement PTO driveshaft can be inclined may be reduced depending on the shape and size of the tractor master shield and the shape and size of the guard of the primary implement PTO driveshaft.

Do not raise implements high enough to damage the tractor master shield or guard of primary implement PTO driveshaft.

Detach the PTO driveline shaft if it is necessary to increase implement height. (See Attching/Detaching PTO Driveline) When using Type 3/4 PTO, inclination and turning angles may be PTO Type

A safety chain will help control drawn equipment should it accidentally separate from the drawbar.

Using the appropriate adapter parts, attach the chain to the tractor drawbar support or other specified anchor location.

Provide only enough slack in the chain to permit turning.

See your John Deere dealer for a chain with a strength rating equal to or greater than the gross weight of the towed machine.

Do not use safety chain for towing.

Transport Towed Equipment Speeds

at Safe

Before transporting a towed implement, determine from signs on the implement or information provided in the implement′s operator manual the maximum transport speed. Never transport at speeds that exceed the implement′s maximum transport speed.Exceedingtheimplement′smaximumtransportspeedcan result in:

Loss of control of the towing unit/implement combination Reduced or no ability to stop during braking Implement tire failure Damage to the implement structure or its components Implements shall be equipped with brakes if the maximum fully loadedweightisgreaterthan1500kg(3307lbs)andgreaterthan 1.5 times the weight of the towing unit.

Example: Implement mass is 1600 kg (3527 lbs) and towing unit mass is 1600 kg (3527 lbs), example implement is not required to have brakes.

Do not transport at speeds greater Implements without brakes: than 32 km/h (20 mph).

Implements with brakes: TS1686-UN: Safety—Towing Unit Towing Implement

Do not exceed the maximum transport speed. This towing unit may be capable of operating at transport speeds that exceed the maximum allowable transport speed for towed implements.
