The Master 103 Series plows are built to be robust, reliable and economic machines. Only available in the Multi-Master version, these plows have a large trash burial capacity with the ability to adjust the traction-bolt models from 28” to 29 1/2” of underbeam clearance. This range features independently mounted skimmers for quick and easy adjustment. The 103 plows have a depth control wheel in line with the frame and a transport wheel option fitted with suspension.

A Variety of Options to Meet Your Operation’s Needs

Options photos: H4, N and VP Moldboard.

Multiple Moldboard Options

  1. H4 Moldboard: The H4, helicoidal, Scandinavian-type moldboard provides well-formed plowing to a normal depth range of 7-12”. The share is fitted with a reversible/replaceable point that greatly increases the life of the share. Recommended for fall plowing, the H4 moldboard is especially suited for heavy and damp clays. Furrow passes are well defined and trash burial is excellent.
  2. N Moldboard: The helico-cylindrical N moldboard plows to a depth of 14”. Designed to be highly versatile, it is cylindrical at front, helicoidal at rear. A low draft ensures a partly broken furrow with excellent trash burial. Recommended for spring plowing, this moldboard is versatile and works well in sandy or clay soils.
  3. VP Slatted Moldboard: The VP slatted moldboard composed of independent and interchangeable slats. Reduces pulling power, due to a lower moldboard surface area. Designed for use in extremely sticky muck and clay soils. Not for use in sand or loam soils or in soils with rocks or stones. The multiple slats allow individual replacement from wear.

Share Point Options

  1. Olympic®: Reversible for maximum efficiency. More pronounced shape at wearing zones on the point for longer life and better protection of the landside. Point is self-sharpening for good ground penetration at all times.
  2. Marathon®: Reversible for maximum efficiency and features a step resulting in better landside protection.
  3. Super Marathon®: Fitted with a tungsten carbide tip. High wear resistance with four to five times the life of a traditional share point. A sharp working edge is maintained for excellent ground penetration. Excellent for highly abrasive soils without rocks or stones.

Plow Leg Protection

  1. 1. Traction Bolt. A clean break of the traction bolt, following a force of 5,280 – 8,820 pounds at the plow point, avoids the risk of nuisance shearing.
    • The bolt runs with the line of force and is pulled apart – unlike shear bolts which are cut
    • The bolt support never deforms or becomes rounded
    • Once the bolt breaks, it simply falls away for quick and easy replacement
    • After years of use the plow bottoms remain perfectly inline
  2. Non-Stop Hydraulic (NSH) Reset. When a field obstacle is met, a rapid breakaway of the plow leg occurs. Once the obstacle is passes there is an increase in pressure, bringing the bottom quickly and firmly back into working position. The system also acts as a shock absorber in rocky ground, increasing plow life.
  3. Heavy-Duty Plow Leg Articulation and Tie Rod. All force is transmitted in a straight line through a one-piece forged and heat treated tie rod.

Easily Make Adjustments

Independent skimmer - photo.

Easy to Adjust Skimmers

Each skimmer is totally independent left from right and is firmly held in a sheath-like support. The skimmers are shear bolt protected and are adjustable in three directions:
  1. Forwards and backwards – with a choice of three positions, the sheath bolts to the leg support via countersunk holes to avoid any risk of free play.
  2. Up and down – rapid and precise height adjustment (7 ½” of adjustment) also with countersunk holes in the skimmer leg for easy locking of the leg at the desired height.
  3. Side to side – for correct adjustment in relation to disc coulter (where fitted).
