Model 8315 - Close Coupled Row Cultivator
The wraparound parallel linkage and close-coupled row unit design make the Orthman 8315 Cultivator maneuverable in the field and on the road. When equipped with the optional western sweep and adjustable ridging wings, the 8315 is the ideal tool for ridging.
Unlike mounting systems that transfer draft force solely through U-bolts that can stretch, distort and break, Orthman’s heavy-duty force-through-mount design and wedge locking system join steel to steel to stand up to the rigors of high residue cultivation.
Reliable weed kill
Orthman’s innovative parallel linkage design allows 8 inches of vertical travel, allowing you to maintain a consistent cut depth for dependable weed kill and precision fertilizer placement when side-dressing regardless of the field terrain.
Precision wrench-free depth adjustment
Provides 9” of quick and consistent tooling depth control with choice of either the depth band coulter or large-tire gauge-wheel option.
Depth Band Coulter Option
The rugged 22” depth band coulter easily slices through surface and sub-surface residue to eliminate interference with the sweep while it simultaneously maintains precise depth control.
Tire Front Option
The 8315’s big tire front option provides superior flotation with its 8” width and 20.5” diameter, all while it simultaneously maintains precise depth control of the row unit for superior weed cutting.
Heavy-Duty Sealed bearings
Reduce your maintenance workload with the 8315’s heavy-duty sealed bearings that allow you to conquer the toughest cultivating conditions.
Precision Tooling Options
Pull soil away from the plant without disturbing the root zone with the optional barring-off discs; when not in use, the wrench-free pin adjustment lets you quickly rotate them out of the way.
Multiple Sweep Options to match your needs
The 8315’s rear shank can utilize multiple Orthman sweep styles, including the single piece sweep, western sweep and super sweep, with blade options to match your row spacing.
If you need to move more dirt for furrow building, the fully width adjustable Orthman ridging wings are available for all sweep options.
Precision nutrient placement side-dressing options (liquid or NH3 fertilizer) allow for dual operations in a single pass for greater efficiency. The dual fertilizer tube option splits to each side of the row to precision place fertilizer close to the crop, while the shank mounted knife option can place the fertilizer deeper in the center of the row.
Adjustable fender packages protect young crops while maintaining the desired ground speed. The 8315 is available with open top fenders to allow for taller crops while the closed top fenders allow for complete protection for the smallest of crops.
Unsurpassed toolbar strength
The 8315 cultivator can be mounted on any of Orthman’s industry-leading rigid or folding toolbars, featuring wide, precision line-bored hinges for smooth folding and extra-engineered strength. The 8315 is available in sizes from 6 to 24 rows in 30” to 40” spacings.
Orthman toolbars are designed around the original principles of the Orthman internal cylinder folding toolbar first developed in the 1970s. The toolbar’s innovative internal folding cylinder design allows the toolbar to fold while freeing up peripheral toolbar space that’s wasted in external folding cylinder models.
Additional Lifting Power
Optional lift assist wheels can be added to configurations 22” and wider to help reduce the tractor load with their 10,000 lb lift capacity and large tire width for better field flotation in wet conditions.
Optional GPS Implement Guidance
For greater precision, the Orthman Tracker® IV implement guidance system can be added to any Orthman cultivator to provide sub-inch weed killing accuracy.
Add an Orthman Nurse-Tank Hitch to add even more side-dress fertilizer capacity to your cultivator. The TH4 features a telescoping and pivoting hitch tab to allow for easier connection to any trailer.
Precision depth control
For additional depth control, optional gauge wheels utilize heavy-duty hubs and an enclosed height-adjustment screw for easy, maintenance-free adjustments
