The New Holland Rolabar Rake is an agricultural implement designed for raking hay and other crops. It is available in several models, including the 57, 256, 258, 260, 216 Unitized Rake, and the 252 Pivot-Tongue Rake Hitch, each offering varying specifications and capabilities to suit different farming needs.

Function Description

The primary function of the Rolabar Rake is to gather cut crops into windrows, facilitating subsequent baling or harvesting operations. The rakes utilize a series of tines mounted on rotating baskets to sweep the crop inward. Different models offer variations in raking width, drive mechanisms, and tine configurations to optimize performance for various crop types and field conditions. Some models are ground-driven, while others utilize PTO (Power Take-Off) or hydraulic power from the tractor. The pivot-tongue rake hitch allows for the combination of multiple rakes to achieve wider raking swaths, increasing efficiency in larger fields.

Usage Features

The New Holland Rolabar Rake offers several features designed to enhance usability and adaptability in the field:

Versatile Raking Widths: Different models provide a range of raking widths, from single-basket configurations to multi-basket setups with the pivot-tongue hitch, allowing farmers to match the rake to their field size and crop volume.
Multiple Drive Options: Depending on the model, rakes can be ground-driven, PTO-driven, or hydraulically driven, offering flexibility based on tractor capabilities and operational preferences. Hydraulic models, in particular, provide more precise control over operating speed.
Tine Material Options: Tines are available in both steel and rubber-mounted versions. Rubber-mounted tines, especially on hydraulic models, can be beneficial for gentler crop handling and reduced wear on the tines themselves, particularly in rocky conditions.
Adjustable Ground Clearance: The 216 Unitized Rake features adjustable tine ground clearance (8 to 11 inches), allowing operators to optimize raking performance for different crop densities and field terrains, minimizing soil contamination.
Transportability: All models are designed with transport in mind, featuring specified transport widths and speeds to facilitate movement between fields. The 216 Unitized Rake, for example, has a transport width of 10 feet.
Optional Accessories: A variety of options are available to customize the rake for specific needs, including:
- Hitch and jack: For easy attachment and leveling.
- Dolly wheels: To improve stability and maneuverability.
- Various wheel/tire sizes (5.00 x 15, 27 x 9.50-15 Rib implement tires, 15" wheels only): To suit different ground conditions and load requirements.
- Flow control kit for single hydraulic rake: For precise hydraulic adjustments.
- Dual wheel attachment: For enhanced stability and flotation.
- Stripper bar support: To prevent crop wrapping around the tines.
- Wide tire adapter: For improved flotation in soft ground.
- Safety chain and hardware: For secure towing.
- Front and rear gauge wheel kits: For consistent raking height.
- High-density rubber 120 tine package: For increased raking efficiency and gentler crop handling.
- Safety tow chain bundle and hardware kit: For added safety during transport.
Pivot-Tongue Hitch Compatibility: The 252 Pivot-Tongue Rake Hitch allows for the use of two individual rakes (256, 258, or a combination of 258 and 260), significantly increasing the effective raking width and overall productivity. This setup is ideal for large-scale operations.
Hydraulic System Requirements (216 Unitized Rake): Requires a tractor with 9 gpm hydraulic flow with 2000 psi relief, four remote outlets, and a double circuit, indicating a need for a capable hydraulic system for optimal performance.

Maintenance Features

The design of the New Holland Rolabar Rake incorporates features that simplify maintenance and ensure longevity:

Sealed Bearings: Models 57 and 256 utilize single ball bearings for tine bars, while models 258 and 260 feature double ball bearings, contributing to durability and reducing the need for frequent lubrication. The 216 Unitized Rake also uses double ball bearings for its tine bars.
Grease-Lubricated Gearboxes: The ground-drive gearboxes are designed with heat-treated gears and clutches running in grease on tapered roller bearings, minimizing wear and requiring less frequent maintenance compared to open gear systems.
Robust Frame Construction: The main frames are constructed from heavy-duty channel steel (3" or 4") and cross-braced with heavy tubular members, providing structural integrity and resistance to bending or damage during operation. The basket is a one-piece, welded heavy steel angle construction, further enhancing durability.
Durable Tine Materials: Tines are made from standard or extra-heavy high carbon steel, or rubber-mounted, offering good wear resistance. The choice of tine material can influence maintenance frequency, with rubber-mounted tines potentially requiring less replacement in abrasive conditions.
Special Accuracy Shaft (Model 57): The drive housing of Model 57 features a special accuracy shaft running on tapered roller bearings, indicating a design focused on precision and reduced wear in critical drive components.
Accessible Components: The overall design aims for accessibility to key components for inspection, cleaning, and replacement, facilitating routine maintenance tasks.
Operator's Manual Importance: The manufacturer emphasizes the importance of reading the Operator's Manual before using the equipment, highlighting that safety and proper maintenance procedures are detailed within. This suggests that adherence to the manual's guidelines is crucial for maintaining the rake's performance and lifespan.
Safety Decals: The presence of safety decals on the machinery indicates that critical information regarding safe operation and maintenance points is clearly marked on the equipment itself, serving as a constant reminder for operators.
