Valmar - Airflo - Model 5500 - Pull-Type Fertilizer Spreader

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

• 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.
