Spectrum is the workhorse of vineyards in California, Michigan, Washington and Chile. The Spectrum's rocking beam front end, 12 inch leveling capacity, 4 cylinder Cummins diesel power pack and attractive entry level pricing make it a practical option for all vineyards.

Tilt-up can be used on vertical or divided canopy trellises. By installing larger "H" frames Tilt-up can tackle trellises up to 52, 60 and 72 inches. For easier adjustment it can be equipped with a compressed air driven width adjustment package. The tilt angle is adjustable up to 45 degrees


Mantis Trunk Shaker
We have a large stock of AGH, Chisholm Ryder and Upright parts and years of experience repairing them.


Simplicity is the key to Sidewinder's success. It has the fewest number of parts of any picking mechanism used in American viticulture. Sidewinder fits into any UpRight, AGH or Chisholm Ryder grape harvester. It can be equipped with our standard Bo-Rods, Full Contact Rods or Quad Rods as needed.

Sidewinder is mostly used on vertical trellises but can be used with crossarms as wide as 36 inches.

Mantis is the leading trunk shaker picking mechanism in the industry. It is unmatched in its speed and effectiveness. The Mantis is designed to be used on cordon pruned vines especially quadrilateral trellis systems. The rails automatically adjust to the width of the vine trunk exerting a continuous force on the vine for smooth, fast, effective harvesting. Full contact rods can be added to the "C" arms for harder to pick varieties. The Mantis' versatility makes it the mainstay of many custom harvesting concerns.

Mantis comes with a variety of "C" arms to fit different trellis systems.

Our new all steel "Tuff Rails" have a substantially increased useful life

Demoger is a star wheel type sorting device that removes MOG (material- than-grapes) from the picked grape before they are deposited in the gondola. Demoger is designed to replace the manual gleaner required on Concord and Niagara harvesters. Some winemakers also require the device to remove unwanted material in the picked mass.

Demogers should only be used in harvesters equipped with magnets so smaller metalic objects are kept from the wine press.

Demogers can be fitted to any make or model of grape harvester and are currently running on AGH Spectrums, UpRight Domestics, BEIs, Nairns, Gregoires and Korvans.

If you really want clean grapes, the Demoger is the only way to go.
