Unverferth Perfecta Field Cultivators

FRAME

PERFECT SEEDBED PREP

The Unverferth Perfecta field cultivator uproots growing weeds so they wilt and die while also loosening and aerating the soil for optimum seed-to-soil or root-to-soil contact, creating the perfect seedbed.

CONSTRUCTION

The Perfecta field cultivator is available in working widths ranging from 40’ to 4’ with an 18’, 15’ or 9’ base on folding models, depending on size, and rigid frame models from 20’ down to 4’. 10’ to 4’ rigid models feature tapered sides and make ideal vineyard maintenance tools at a fraction of the cost of a disk.

BEDDED CROPS

Models for established bed preparation are available in a variety of row widths, from 28’ to 7’ to work up established beds and provide a plant or seed-ready environment.

WING FLEX

28’ to 18’ models feature 5 degrees of upward and downward wing flex to follow field contours, or the wings can be set to rigid if desired. 40’ to 30’ models feature 15 degrees of flex upward and 5 degrees of flex downward for the most consistent tillage action.

FOLDING MODELS

All folding models are complete with 3,000 PSI-rated hydraulic hoses, including couplers and protectors, to fold the wings. 40’ to 30’ models feature a wing-fold flow-divider valve that allows the wings to fold evenly, allows the operator to set the working position, and raises the entire unit on end rows without folding the wings.

GAUGE WHEELS

40’ to 10’ Perfecta field cultivator models are standard with gauge wheels to set the proper working depth and provided added stability in-field. Bedded crop models and 15’ to 10’ rigid models utilize 16.5 x 6.5-8 single tires, 20’ to 18’ rigid models and 28’ to 18’ folding models with 8’ or 7’ wings utilize 20.5x8 dual tires, 28’ to 18’ folding models with 6’, 5’ or 4’ wings utilize 20.5x8 single tires and 40’ to 30’ models utilize 7.60 x 15 single tires.

S-TINES

SEEDBED PREP

The S-Tines are spaced 18” side-to-side and 20” front-to-rear for an overall spacing of 6” which permits superior residue flow. All models feature three rows of staggered S-Tines that till from 2” to 6” deep. Depending on the soil conditions, 4 to 9 horsepower per foot of Perfecta on the tractor is recommended.

MODELS

Model 10 features ½” thick by 1 ¼” wide S-Tines with a 2 ¾” wide goosefoot shovel for effective soil finishing in previously worked soils.

LEVELING BAR

A SMOOTH SOIL PROFILE

The standard leveling bar on the Unverferth Perfecta field cultivator is located directly behind the S-Tines to knock down ridges and leave a level surface for the most effective conditioning.

TOOL-FREE ADJUSTMENT

The leveling bar features tool-free adjustment with spring down pressure so the operator can fine-tune the aggressiveness, or it can be pinned up in high-residue fields.

LEVELER STYLE

The diagonal and curved round tooth leveling bar features heat-treated ¾” thick by 12” tall teeth that can handle heavier soils with moderate residue.

FINISHING ATTACHMENTS

SINGLE ROLLING BASKET

The single Rolling Harrow basket attachment is available for all models of Perfecta field cultivators and features an exclusive, 12” diameter basket with forward-angled blades that dig into the soil for increased penetration and tillage action. For extra firming action, the basket can be reversed to angle the blades rearward.

DOUBLE ROLLING BASKET

The double Rolling Harrow basket attachment is available on 40’ to 30’ and 15’ to 10’ rigid models and features an aggressive 12 ½” diameter lead basket coupled with a passive 12.5” diameter trailing basket. The basket assembly can be reversed for additional firming action in lighter soils.

SINGLE DRUM ROLLER

Standard reversible scrapers keep the drum clean during operation and the patented 4-bolt greaseless bearings utilize a 1 1/8” square bore, triple-lip seals and an exclusive shoulder construction that prevent the seals from reversing.
