8450 Cultivator

Strong and cost-effective cultivation

The Orthman 8450 is explicitly designed to be the strongest, most cost-effective cultivator and fertilization tool in the industry. With its ability to pull two shanks per row unit, it offers virtually endless cultivation and fertilization options.


Parallel Linkage

Wraparound Parallel Linkage

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.

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.

Heavy-Duty Sealed bearings

Reduce your maintenance workload with the 8450’s heavy-duty sealed bearings that allow you to conquer the toughest cultivating conditions.

Heavy-Duty Mainframe

Orthman’s industry-leading 1tRIPr precision tillage tool was designed around the time tested mainframe and structural concepts of the 8450 row crop cultivator. The 8450 is famous for its strength.

Simple. Rugged. Reliable.

The 8450 tail section was designed to handle multiple shanks and tools, all while being simple in design and strong enough to handle whatever is thrown at it, season after season.

Precision Tooling Options

Multiple Sweep Options to match your needs

The 8450’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.

Single Piece Sweep

Cut Widths 14” to 26”

Western Sweep

Cut Widths 16” to 28”

Ridging Wings

If you need to move more dirt for furrow building, the fully width adjustable Orthman ridging wings are available for all sweep options.

Side-dressing 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.

Ripper Shank option

The 8450 can be equipped with an optional inter-row ripper shank that can be used while still utilizing the rear shank for cultivation and fertilization. The inter-row ripper shank increases water penetration and eliminates compaction and can be used across all rows or just behind tractor tires.

Unsurpassed toolbar strength

The 8450 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 8450 is available in sizes from 6 to 24 rows in 30” to 40” spacings.

Patented Design

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.

Nurse-Tank Hitch

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.
