Resumen del manual
Section 1 page 10 “Operating Instructions” in this Manual Section 2 page 12 Lubricate the cutter as needed. Refer to "Lubrication" Section 5 page 19 Check the cutter initially and periodically for loose bolts & pins, "Torque Values Chart". Section 6 page 24 Make sure all guards and shields are in place. Section 1 page 3 Gearbox Gear Lube Section 5 page 20 NOTE: The center deck height is controlled with the standard ratchet jack or the optional hydraulic lift cylinder. 4. Increase throttle to approximately 500 RPM and slowly engage PTO. Ensure that all power shafts are rotating and that cutter has no vibration. 5. Continue to increase throttle to full PTO speed before commencing forward operation. Refer to Figure 2-2: Optimum Ground speed depends on the density of the material being cut, the horsepower rating of the tractor, and (in some cases) terrain. If the cutter-to-tractor PTO is a standard conventional shaft, avoid tractor-to-cutter turning angles exceeding 35°. If equipped with a Constant Velocity PTO shaft, the turning angle may be increased to 80°. These extreme angles are intended for intermittent usage only and not prolong usage. Plan your field cutting to minimize the number of turns as well as the extreme angles where turns are necessary. Transport Link Figure 2-1 13885 Conventional U-Joint PTO Figure 2-2 11934 13 Section 2 Operating Instructions 7/14/08 RC45180 & RCM45180 Rotary Cutter 312-382M Land Pride Table of Contents This cutter was designed to cut grass and medium to heavy brush in pastures, right-of-ways, and certain ditch/ terrace areas. This cutter is also useful for heavy row crop cutting. Avoid areas where small trees or brush diameters exceed 2". Do not attempt to operate this cutter in areas where rocks, steel, glass, concrete, wire, or other hard, foreign objects may be present. ! WARNING! Do not operate this cutter under any terrain conditions where the wing angle exceeds 45° up. Ensure that the wing wheels are in continuous ground contact at all times. Use the float position of your tractors hydraulic system to provide automatic wing float position for varying terrain conditions. Transporting ! DANGER! Rotary Cutters have the ability to discharge objects at high speeds; do not operate this cutter along highways, roadways or other areas where people may be present unless approved guarding has been installed and properly maintained. Factory approved guarding includes front and rear safety chain, deflector skirts or other shields. Contact your dealer or call Great Plains Manufacturing, Inc. for the name of your nearest factory authorized dealer. ! CAUTION! When traveling on public roads whether at night or during the day, use accessory light and devices for adequate warning to operators of other vehicles. Comply with all federal, state and local laws. ! CAUTION! Always disengage tractor PTO before transporting cutter to avoid injury from thrown objects or blade contact. 1. Select a safe ground travel speed when transporting from one area to another. When traveling on roadways, transport in such a way that faster moving vehicles may pass you safely. 2. Reduce tractor ground speed when turning. Leave enough clearance so the cutter does not contact obstacles such as buildings, trees or fences. 3. When traveling over rough or hilly terrain, shift tractor to a lower gear. 4. Raise cutter to transport position using the hydraulic lift or rachet jack. Careful: When raising to transport position, be certain that PTO shaft does not contact tractor or cutter tongue. 5. Raise both wings to 85° vertical position. The automatic wing latches should engage. Check to be sure they are fully latched. Refer to Figure 2-3: 6. Engage transport lock (#1) by removing lock pin (#2) and rotating transport lock to 45° position. Insert lock pin through detent notch and secure with hair pin cotter (#3). 7. Slowly lower the cutter until transport lug of axle weldment contacts transport lock block. 8. Reduce tractor ground speed when turning; be sure tractor wheel does not contact cutter when turning. Leave clearance so cutter does not contact obstacles such as buildings, trees or fences. 9. The cutter should be transported no faster than 15 mph when equipped with laminated or solid tires, and 30 mph when equipped with pneumatic tires. ! CAUTION! The cutter is 8’ 9" wide and care should be taken when encountering oncoming traffic and roadside obstructions. Parking The following steps should be done when preparing to store the cutter or unhitch it from the tractor. See also “Storage”, on page 18 for additional information on long term storage of your cutter. 1. Park the cutter on a level, solid area. 2. Shut off tractor engine and engage parking brake. 3. Install jack & crank up the jack until it is supporting the unit. 4. Unhitch from tractor.
