Frontier GX11 Series Grinder Mixer

Double tap to zoom



The 3.7-m (12-ft) hydraulically controlled unloading auger is standard equipment. It has a reach height of 19 ft at 53 degrees, can rotate 300 degrees, and is controlled from the tractor's operator station.
An adjustable slip clutch for the unloading auger rotation provides protection against impact with a building or bin.
A manually operated, slide-style door opens easily for unloading.

The 53-cm (21-in.) hammer mill has 66 thin, four-way reversible steel-alloy hammers that slice the material.
As slicing occurs, a suction fan draws ground feed through the 600-cu in. screen area and allows a uniform mix. This mill and hammer design also reduces horsepower requirements.

The supplement hopper is located on the left side of the grinder mixer. It is 58.4 cm wide and 45.7 cm long (23 in. wide and 18 in. long) and equipped with a sack cutter. The mouth opening is 88.9 cm (35 in.) above the ground.

Big capacity means fewer loads to be ground, mixed, and delivered to feeders and bins.

The 0.91-m (3-ft) folding discharge auger extension kit consists of a (0.91-m) 3-ft length of auger, which is attached on a pivoting mounting bracket to the end of the 3.7-m (12-ft) unloading auger.
The 1.8-m (6-ft) folding discharge auger extension kit consists of a 1.8-m (6-ft) length of auger, which is attached on a pivoting mounting bracket to the end of the 3.7-m (12-ft0 unloading auger.
The discharge auger cradle extension kit holds the 0.91-m (3-ft) and 1.8-m (6-ft) auger extension in position for transportation.

NOTE: The folding auger extensions must be folded back and locked in position for transport.

The swinging intake auger has a diameter of 30.4-cm (12 in.) and a length of 2.1-m (7 ft.) In the operating position, the intake auger rests on the ground. The height from the ground to the top of the mouth intake flares is 50.8 cm (20 in.) The swinging intake auger is hydraulically driven with a variable-speed control and feeds a variety of grains into the hammer mill.

Two Digi-Star® electronic scales are available for the GX1117 Series Grinder Mixer.
The Digi-Star EZ2000 electronic scale measures the total weight of material in the mixing chamber.
The Digi-Star EZ3200 electronic scale with an external horn measures the total weight plus the weight of each ingredient added to the mix.
Digi-Star is a trademark of Digi-Star, LLC.

Twelve hammer mill screens are available as attachments for the grinder mixer. Sizes range from 3.175 mm to 50.8 mm (0.125 in. to 2 in.).
Screens are stored on the left side of the machine.

Unloading auger extensions are available in 0.9-m and 1.8-m (3-ft and 6-ft) lengths and are folded manually.

Mill screens field conversion kits are used for grinding a variety of sizes and types of grains and shelled and ear corn.
All attachments, their respective sizes, and uses are listed below, and all are for use on the GX1117 Grinder Mixer.

A gravity feed hopper with two heavy-duty 102-mm x 457-mm (4-in. x 18-in.) magnets catches metal debris.

The 35.6-cm (14-in.) vertical mixing auger with a 76.2-cm (30-in.) base is designed to thoroughly mix the ground feed and supplements.
Mixing is accurate and consistent load after load.

The GX1117 is available with a 540-rpm power take-off (PTO) or 1000-rpm PTO. The hammer mill is powered with an eight A-section-banded V-belt for a positive drive.
The drive also features a quick-release pin to disengage the hammer mill.

The self-contained hydraulic system drives all of the feeding attachments and unloading mechanisms. The hydraulic system is supplied by a hydraulic motor with 39.75-L/min (10.5-gpm) flow. A cyclonic reservoir provides circulation to cool the hydraulic oil.
