Model OTG - Seed Drill


Agriculture drills, both grain and grass, are designed to plant either as a no-till into residue or be configured to plant conventional, prepared seed beds. These drills are not versatile enough for today’s farmers who demand more when faced with sites that need drills to change from one mode to another as conditions change. The Truax On-the-Go Drill adapts to your site conditions and even to seed bed variances within a field.

Five reasons the Truax On-The-Go Drill should be a part of your operation:


This is the drill you will hand down to the next generation. Its double-row bearings handle loads better than the common single-row types and extend bearing life cycle. Rubber torsion assemblies in the planters eliminate moving parts prone to wearing out. Top to bottom and side to side, we meticulously engineered this drill to last.


Seed bed variations can be overcome by the OTG’s interchangeable, leading press wheels that can be moved in to place hydraulically to firm the seed bed before the double disc places the seed.


Achieve consistent seeding rates every time. The drill’s output adjustment lever enables precise seed metering. Calibrate and set the drill once and return to the same output setting every time.


Site conditions and seed species may require unique seed placement. The OTG can easily adapt to plant many different types of sites. It is possible to drill with the standard double disc openers or to interchange optional imprinters for seeding surface sown species.


Different levels of crop residue on the same field can be addressed by raising and lowering the drill’s hydraulically activated no-till assemblies.

TRUAX – the global leader in the manufacture of drills and planters to sow native grasses, legumes and grains has set the standard for drill features to meter and place these seeds in order to achieve optimal establishment. When reviewing the features of different brands of drills to meet your specific needs be sure to include the following which are common to all Truax drills and planters: Including the On The Go (OTG Series), Flex II Series, Trillions, and Pull Broadcasters.


  • An optional Output Reduction Kit is available to reduce seeding rates for specialized applications including low rate CRP mixes.
  • Tapered roller bearings with integral rubber seal on rear bearings used on all no·till coulters.
  • Separately metered seed boxes for grains, small seed and legumes, and a third box for fluffy native species.
  • Depth of planting controlled by metal depth bands on all planting discs.
  • Digital acre meter strategically placed on end of drill for easy access.
  • Ground clearance of disc blades when in transit will be 10″ or more, press wheel clearance to be 14″ or more.
  • Optional 3″ x 16″ smooth crown leading press wheels that are interchangeable with the leading no-till.
  • Trouble free delivery of all seeds from the seed boxes to the drill openers. This is accomplished through large seed boots and by maintaining a vertical straight-line flow in the fluffy seed boot, a nearly vertical drop from the cool season/small grain box, and a smooth tube from the small seed box.
  • Seed from all seed boxes is delivered between the double disc openers. The rolling disc opener carries the seed into the soil for proper seed placement. Seed is not broadcast behind the disc opener.
  • EZ-OFF depth bands on every double disc control planting depth. Shallow planting is required for most grass and legume species. A shallow, uniform planting depth results in a uniform seedling emergence. Depth bands are available in four sizes depending on the desired planting depth and soil texture.
  • Scrapers on the disc openers and the depth bands keep moist soil from building up and affecting planting depth and seed placement.
  • Press wheels operate independent from the planter assembly. The press wheels on Truax Drill track directly behind the disc openers to firm and press the soil around the newly planted seed without controlling the depth the planting unit is operating.
  • Interseeding or no-till drilling in crop residue or sod is easily accomplished using the concave, notched, fixed mount Trash Plows, or the optional 24 or 13 wave coulter on a caster style mount.
  • End wheel drive powers the seed metering mechanism to assure a constant flow of seed to the disc openers under all planting conditions.
  • A tongue style hitch easily converts to three-point style by adding Category 2 or 3 hitch pins to pre-drilled holes in the frame. A folding tongue is an option for ease of transport and storage.

TRUAX – has raised the bar with the introduction of the On-The-Go series of grass and grain drills. The technology “benefits” achieved with the OTG drills makes this machine the “GO TO” tool for serious production farmers. If your operation is the “best in class” then demand the OTG features on your next drill.


  • Hydraulically activated no-till raises 14″ above ground for planting prepared conventional seed beds and hydraulically lowers 14″ and locks into place when inter seeding or no-tilling.
  • Double row, ball bearings used on all planting discs.
  • Staggered planters with a minimum of 11″ stagger between ranks.
  • Optional Brillion style 4″ x 14″imprinters, interchangeable with double disc openers, to press surface sown seed such as Wyoming Big Sage into the soil.
  • Calibration procedure that requires 4 1/4 rotations of calibration nut to determine output.
  • Automotive style throw out bearings facilitate the movement of the metering shaft for both small seed, legume seed box and the cool season grain box.
  • Drill to have both a rear walk board with access ladder as well as a front metal walk board with access step to facilitate the filling of all seed boxes.
  • End wheel tires are 2:55/70 x R22.5 16 ply rating, retread or new, (specify) highway tread.
  • Dual hydraulic lockout valves on tongue.
  • Folding tongue for transport or storage.
  • Out – put reduction kit to achieve extremely low seeding rates.
  • No-till assemblies available in four styles: a) Aggressive – 13-1/2″ concave, angled to line of travel for sod seeding. b) “Hi-trash”- 18″ concave, mounted parallel to line of travel – works best in loose litter. c) agricultural style, 18″ flat blade with 24 wave edges for light residue or crusty soils. d) agricultural style, 18″ flat blades with 13 wave edges for intermediate/heavy residue.
  • Ground clearance of disc blades when in transit will be 10″ or more, press wheel clearance to be 14″ or more.
