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, Valmar’s 5500 Pull-Type self levelling booms feature extra strong all stainless steel construction with break-away boom tips for added protection. The standard unit comes with a 40 ft. boom, while the Row Crop uses a 36 ft. boom. An optional kit is available to extend the Row Crop boom to 38 ft. The booms fold manually.

1000 RPM P.T.O. Fan Drive

The 5500 PT fan is driven by a 1000 RPM power take off system. The constant velocity drive shaft is 13⁄8 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 13⁄4 in. 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 1⁄2 width application.

Extremely Accurate Metering Gearbox

The mechanical gearbox uses 60 different gear ratios for metering rates at 5% increments. Rates as low as 4 lb./acre for herbicide application and as high as 400 lbs. of fertilizer/acre at 5 MPH. A bulk density scale is supplied to help match your fertilizer blend to the application rate charts.

Hydraulic Drive Metering

The 5500 PT metering can be adapted for hydraulic drive for V.R.T. applications.

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 ft. boom for application in 36 in. rows.

Optional Marking Systems

Select from a mechanical disc marker or a Simpson SKS foam marker.

Roll Tarp Included

All 5500 Pull-Types come with roll tarp installed.

Optional Hopper Screen

Keeps out foreign material.

Hydraulic Drive Options

Hydraulic drive metering.

Hydraulic fan drive.

Hydraulic Drive Metering

A complete Rawson or Raven system can be supplied for customers interested in variable rate applications. Or a basic drive can be installed including a hydraulic motor only, for the customer to complete with a system of their choice. Does not include radar, servo valve, encoders, controller/monitor, cables etc.

Hydraulic Fan Drive

Valmar offers an optional hydraulic fan drive. This option uses a belt drive with a 32 CC hydraulic motor requiring 23 gal./min. hydraulic flow operating at 1885 PSI which is within the capability of many of today’s higher capacity tractors.

Single Axle Option

Features a single axle with 12 ply, 550/60-22.5 flotation tires at 90 in. center to center. Avoids the skidding associated with tandem axles when turning.

Available with single axle and flotation tires and hydraulic fan drive.

28 groove roller segments.

Row crop tires (9.00 x 20) on tandem axle.

Herbicide and small seed, 28 groove metering roller.

Optional hopper screen keeps out foreign material.

60 speed metering gearbox drives the 12 groove stainless steel fertilizer rollers.
