VALMAR AIRFLO 5500 PULL-TYPE FERTILIZER SPREADER
Achieve Superior Accuracy and Uniform Placement Over Entire Width of Boom
Stainless Steel Booms
Designed for commercial rental operations, Salford Valmar’s 5500 pull-type self-leveling booms feature extra-strong, all stainless steel construction with breakaway boom tips for added protection. The standard unit comes with a 40-foot boom, while the row crop model uses a 36-foot boom (an optional kit is available to extend the row crop boom to 38 feet). Booms fold manually.
1000 RPM PTO Fan Drive
The 5500 PT fan is driven by a 1000 RPM power take-off system. The constant velocity drive shaft is 1 3/8 inches in diameter, 21 spline, and is equipped with an over-running clutch to prevent damage from sudden disengagement of the tractor PTO system. An optional 1 3/4-inch 20-spline shaft is available.
Ground Driven Metering System
A hydraulically engaged metering system provides consistent application rates regardless of ground speed. Either side can be manually disengaged for half-width application. The 5500 PT metering can be adapted for hydraulic drive for variable rate technology applications.
Hydraulic Drive Metering
Salford Valmar offers an optional Raven Omniseed system for a variable rate technology-ready machine (controller sold separately). Or basic drives can be installed, including a hydraulic motor only, for operators to complete with a system of their choice (does not include radar, servo valve, encoders, controller/monitor, cables, etc.).
Extremely Accurate Metering Gearbox
The mechanical gearbox uses 60 different gear ratios for metering rates at five percent increments. Rates as low as four pounds per acre for herbicide application and as high as 400 pounds of fertilizer per acre at 5 miles per hour. A bulk density scale is supplied to help match your fertilizer blend to the application rate charts.
Apply Herbicides or Small Seeds
With an optional kit, the 5500 PT can accurately apply small seeds or herbicide at low rates, something that is not possible with a spinner-type spreader. The kit consists of two 28-groove metering rollers and a fan intake reducer.
Ideal for Row Crop Application
Tandem walking beam axles are standard on both models. The row crop unit is equipped with narrow tires and a 36-foot boom for application in 36-inch rows.
Optional Marking Systems
Select from a mechanical disc marker or a Simpson SKS foam marker.
Roll Tarp Installed
Hopper screen kit keeps foreign material out.
Hydraulic Fan Drive
Salford Valmar also offers an optional hydraulic fan drive. This option uses a belt drive with a 32 CC hydraulic motor, requiring 23 gallons per minute hydraulic flow when operating at 1885 PSI – well within the capability of many of today’s higher capacity tractors.
Features a single axle with 12-ply, 550/60-22.5 flotation tires at 90 inches center to center, avoiding the skidding associated with tandem axles when turning.
