Saves Labor, Time and Money

Quickly Installed

Adaptable to single or double action hydraulic systems, the complete unit can be installed the first time on almost any make gravity flow wagon in less than an hour. Because it is mounted on just two pins, it is on or off in two minutes or less.

Easy to Operate

Finger-tip controls at both the discharge end and the tractor, plus variable delivery speed makes it easy for the operator to fill grain drill or planter boxes without waste or spillage. The hopper is practically self-emptying and the auger (available in 11, 14 or 16 foot lengths) swings 180 degrees to allow discharging from ground level up to 13 feet. The auger folds out of the way when not in use for easy transport.

Filling Planter with Fertilizer
Use Model HF-11 for 4 row wide or 6 row narrow; Model HF-14 for IHC air planters. Auger does not have to be cleaned out between fillings.

Filling Drill With Seed
Auger discharge height is adjustable, and swings easily to fill drill hopper. Flow is controlled at the discharge end of the auger. Note Hydra-Fold's patented way of mounting auger below the hopper; no spilling and no waste. This results in nearly complete clean-out of the hopper. It also elminates the churning action of an auger operating in an open container.

Filling Planter With Seed
HF-14 Auger filling seed hoppers on 12 row IHC planter with soybeans. Wagon does not have to be moved to fill both hoppers.
