GENERAL SAFETY

The following are general farm safety precautions that should be part of your operating procedure for all types of machinery.

1. Protect yourself.

When assembling, operating and servicing machinery, wear all the protective clothing and personal safety devices that COULD be necessary for the job at hand. Don't take chances.

You may need:

• a hard hat.

• protective shoes with slip resistant soles.

• protective glasses or goggles.

• heavy gloves.

• wet weather gear.

• respirator or filter mask.

• hearing protection. Be aware that prolonged

exposure to loud noise can cause impairment or loss of hearing. Wearing a suitable hearing protective device such as ear muffs (A) or ear plugs (B) protects against objectionable or loud noises.

2. Provide a first-aid kit for use in case of emergencies.

3. Keep a fire extinguisher on the machine. Be sure the extinguisher is properly maintained and be familiar with its proper use.

4. Keep young children away from machinery at all times.

5. Be aware that accidents often happen

when the operator is tired or in a hurry to get finished. Take the time to consider the safest way. Never ignore warning signs of fatigue.

are the key to safety.

OPERATION

PREPARING THE TRACTOR

1. Select proper tractor size:

For 21', 25' or 30' units required is 40 hp (30 kw) and minimum tractor weight is 5000 lbs. (2270 kg). For 36' unit hp (38 kw) and minimum tractor weight is 6000 lbs. (2720 kg). For all sizes, minimum hydraulics required are 1800 psi (12400 kPa) pressure with dual remote capability.

2. For tractors with variable PTO speed, select

540 or 1000 rpm to match windrower speed option. See "Preparing the Windrower" in this section.

3. Adjust tractor drawbar to meet ASAE Standard

specifications as listed below for the PTO speed to be used (540 or 1000 rpm). An improperly located drawbar may damage the universal joints of the implement driveline, and/or affect machine performance

Be sure the following specifications are met:

(A) 14 in. (356 mm) for 540 rpm. 16 in. (406 mm) for 1000 rpm.

(B) 6 to 12 in. (152 to 305 mm)

NOTE: An offset drawbar (D) can be turned over if required to meet specifications (B) and (C).

4. Secure the drawbar so the hitch pin hole is

directly below the driveline.

NOTE: If the tractor has a three point hitch, raise the lower links as high as possible, to prevent damage.

5. Attach support (E) for hitch chain to suitable

location on tractor drawbar, maximum 6 inches (150 mm) from hitch pin hole. For 36 ft. unit, also note item 7.

OPERATION

PREPARING THE WINDROWER

1. Be sure windrower is set up to match tractor

PTO speed. A quick way to check is to measure the outside diameter of the driven pulley (A):

9-1/2 inch (240 mm) - 540 rpm

12-1/2 inch (320 mm) - 1000 rpm If not matched, and tractor PTO speed cannot be varied, order a conversion kit from your windrower dealer. (Kit includes front yoke, decal and instructions.)

IMPORTANT: To avoid machine damage, follow instructions provided in kit for removal of main drive pulley. This procedure is also detailed under "Removal of Main Drive Pulley" in Maintenance/ Service section.

2. Use correct hitch type: For tractors with clevis type drawbar, windrower hitch is compatible without modification. For tractors with straight drawbar, an optional hitch plate (B) is available to convert windrower hitch to clevis type.

To install:

- Remove bolt (C) securing hitch chain.

- Position plate (B) under hitch and replace bolt (C) to secure hitch chain.

- Install bolt (D) from option kit and secure with locknut.

3. With tractor drawbar adjusted to recommendations listed under "Preparing the Tractor", adjust the drive frame vertically at (E) so telescoping driveline (F) is in straight line with tractor PTO.

NOTE: The telescoping driveline (F) should slide under hand pressure. Grease if required.

4. Install quick coupler tips matching the tractor to be used on the two hydraulic hoses going to the tractor.
