Unverferth 2650

HOPPER

LARGE CARRYING CAPACITIES

Pull-type models include 2650, 2250, 1850, and 1450 with capacities of 26 tons, 22 tons, 18 tons, and 14 tons respectively. Chassis-mounted hoppers are available in models 2050, 1850, 1650, 1450, 1350, 1250 and 1150 and feature capacities of 20 tons, 18 tons, 16 tons, 14 tons, 13 tons, and 8.5 tons respectively.

PREMIUM DESIGN

The hopper is 102” wide with 12" sideboards (except for the 1250 model) and is constructed of premium 304 stainless steel for the most corrosive-resistant, longest-lasting finish.

DUO-, TRI- & QUAD FORCE

MULTI-HOPPER OPTIONS

The Pro-Force dry fertilizer spreader can be equipped with multi-hopper options that allow you to spread 2, 3, or 4 separate products at the same time, each with a variable rate. The Duo-, Tri-, and Quad Force options can be added or removed from the Pro-Force dry spreader main hopper at any time because the back panel of the main hopper does not need to be removed.

CONVENIENCE FEATURES

The hopper features a standard bin-level sensor that alerts the operator when the hopper is getting low on material. The standard window in the front hopper panel allows the operator to easily see the contents inside.

SPREADING SYSTEM

PINPOINT ACCURACY

Spread common fertilizer up to 90’, lime and gypsum up to 60’, soybean and cover crop seed up to 70’, and compost up to 45’ with pinpoint accuracy because of the field-proven spinner design.

SPINNER DISKS

Dual 30” spinner assemblies feature a ¾” deep dished design and 6 of the most aggressive fins in the industry that produce a wider spread pattern with precision application rates, even in windy conditions. The ¾” dish design in each spinner disk optimizes the departure angle of the dry material for consistent spread patterns.

BELT-OVER-CHAIN

The 34” wide belt-over-chain conveyor system provides a leak-free seal for accurately dispensing material onto the spinner disks. The vee-cleat rubber belt is fastened to the chain for worry-free operation.

END GATE

The fixed material divider at the end of the belt-over-chain conveyor ensures even distribution to each spinner. The removable hillside baffle holds material in place when traveling through uneven terrain. The end gate door features a convenient handle and measurement decal to ensure the door is opened to the correct height.

PULL-TYPE SPREADERS

CAPACITIES

Pull-type models are available with an 840, 710, 580, or 450 cubic-foot capacity hopper, which are among the largest in the fertilizer spreader industry! 840 cubic foot model is for spreading compost or poultry litter only and all models feature standard 12” sideboards.

CONTROLS

The Raven RCM ISOBUS rate controller is standard equipment and allows the operator to use the tractor’s virtual terminal screen to control the rate. An on/off master foot switch is included in conjunction with the ISOBUS rate control system.

UNDERCARRIAGE

Choose from high-flotation IF900/65x32 CFO single tires or if equipped with row crop duals, choose 480/80x46, VF380/90x46 or 320/105x54 tires depending on row spacing.

IN-LINE WALKING TANDEMS

Models 2650, 2250 and 1850 are available with an optional in-line walking tandem undercarriage that allows for 15° of upward and 15° of downward movement for a total of 30° of travel in the field.

TRACKS

The optional 36” wide x 112” long hydraulically tensioned track system features a 106” rigid axle for the greatest in-field flotation. The track system features a 2-bogie design, 32” main end wheels with 8-bolt hubs, cast-iron pivoting bogie wheels and convenient pressure gauge for verifying the belt tension.

ADDITIONAL FEATURES

Standard protective covers under the hopper prevent corrosive material from falling onto the pull-type undercarriage. The pulling tractor requires 38 gallons per minute of hydraulic flow, 2 SCV remotes, and a case drain for proper operation.

PULL-TYPE OPTIONS

For accurate weight recording and in-field calibration, the optional scale system features an innovative design for accurate weight measurements. Models 2650 to 1850 feature a 6-point shear-beam load cell design and the 1450 model features a 4-point shear-beam load cell design. The scale system will work directly through the VT screen in your tractor cab, or you can opt for a separate 410 indicator to operate the scale system.

CHASSIS-MOUNT SPREADERS

CAPACITIES

Chassis-mount spreaders are available with a 645, 580, 515, 450, 415 or 270 cubic-foot capacity hopper. The 270 cubic-foot models is specifically designed for self-propelled sprayer chassis and can be equipped with optional 4” or 12” sideboards to increase the capacity to 300 or 385 cubic feet.

MOUNTING

When mounting to a floater chassis or a self-propelled sprayer, it is always important to note the maximum capacity of the chassis when mounting a spreader hopper. Lift lugs are standard and permit easy handling when installing or removing the hopper.

CHASSIS-MOUNT OPTIONS

Options for the chassis-mount spreaders include mud flaps to protect the front and rear of the unit, an oil cooler system, a hydraulic unloader valve for tractors without a PTO, a hydraulic gear pump for mounting to a chassis with an air system and ball valves for chassis that do not have hydraulic on/off.
