Dowdeswell 105 Series reversible ploughA re-scaled version of the popular and proven 140 Series plough range. The 105 Series plough range has been developed with today’s farmer and contractor in mind.

Available with shearbolt protection on a four or five furrow frame (each able to take an extra furrow attachment), or with spring reset protection on a four furrow basic frame, able to take an extra furrow attachment.

With manual furrow width adjustment from 14” to 20”, for use in the furrow behind tractors of up to 190hp. A range of fully mounted, reversible ploughs.

Using many features of Dowdeswell’s 140 Series range of ploughs the 105 Series range has an already proven history with scale changes to reduce weight for a smaller range of tractors being the major contributing influence for today’s design.

Dowdeswell’s renowned quality engineering has been built into this plough range which, together with our two year warranty, offers outstanding value.


Hydraulic Alignment & Furrow Width Adjustment

Patented parallel sideshift allows easy, hydraulically operated, on-the-move adjustment of the front furrow width and matching to the tractor wheel widths.

Hydraulic adjustment of the beam angle allows for simple setting of the plough alignment initially and when changing furrow widths to ensure the tractor top link is true. Coupled to a memory system it allows the plough to close down the beam angle, turnover and reset the beam angle to its previous position, all on one spool movement.


Cast Headstock

Dowdeswell’s 105 Series plough uses a high tensile cast steel headstock base for excellent durability, whilst allowing for category 2, 3 & 3 narrow attachment to the tractor.

The turnover runs on low friction taper roller bearings to provide a smooth and consistent turnover.


Easy Manual Adjustment

Manual Adjustment (MA/MR) models feature the proven Dowdeswell adjusting system, being easy and accurate, with no need to remove or replace bolts, re-positioning the mouldboard, skims and disc together.


Depth Wheel

Fitted as standard with a depth only land wheel using a simple, reliable and proven damped turnover complete with individual adjustment of the right and left hand ploughing depths.

A large tyre profile is provided as standard to keep ploughing depths consistent.

As an option on the 105 Series, a combination depth/transport wheel can be specified.  Taken from the 140 Series range which has a fully proven history.

The depth/transport wheel assembly features spanner-less depth adjustment and a single pin operation from work into transport.


Shearbolt Protection

All 105 Series shearbolt ploughs use the same leg, skim and disc from the 140 Series.  Using a lightweight high strength fabrication of the leg bracket for durable performance.


Spring-Reset Protection

Patented Six ball pivot system allows the body to trip sideways to either side as well as vertically.

The coil spring acts via a simple lever and tension rod for ease of adjustment and maintenance.

The Dowdeswell system allows for a very high point lift with the geometry designed so the spring loading reduces as the body rises clear of the ground.

Dowdeswell UCN MouldboardUCN

Standard on all ploughs

The UCN body is a general-purpose unit recommended for all soil types at depths from 5” to 10”.  The UCN has a steeper breast than the YCN giving a faster turn to the soil, promoting complete inversion with good breakage.

Dowdeswell UCN and SCN plough point Point:  Choice of a large reversible point or a small (single bolt fixing) reversible point which gives better penetration and improves the soil flow across the mouldboard.

Wing:  Choice of 16” (standard wing) or 18” (wide wing for widths up to 18”)

Dowdeswell plough YCN mouldboardYCN

Option - Extra £85 per pair

Traditionally known as a “ley” body, this long, slim design is used predominantly for shallower work at depths from 2” to 8”.  The YCN is a low pressure mouldboard, well suited to sticky soils which do not scour easily. Dowdeswell plough point for YCN mouldboardFor extreme conditions, Dowdeswell offers a flush-fitting point in place of the standard reversible point which sits on top of the wing.  Recommended ploughing widths are from 12” to 16”.

Ordering Code: SLATTED-DB

Please quote skim option when ordering.

All plough prices include skims on either rectangular or round skim stalks.

A near essential component, the skim removes a portion of the outside edge of the furrow being inverted, placing it and any vegetation into the furrow bottom to be covered by the turning furrow.  Working without skims, the mouldboard would struggle to achieve complete trash burial.

Dowdeswell plough skim - rectangular stalk shapeRectangular Skim Stalks

Sole fitment on all current Dowdeswell shearbolt ploughs except the 100 Series range they have a fixed working angle.  The rectangular stalk benefits from having a pin and hole series for simple, spanner-less, depth adjustment.
The rectangular shank skim is standard fitment on all ploughs.

Round Stalk Skim

Not available on DF 105 MA. Available as an option on DF105 MR.

Round Stalk ‘K’ Type Skim

This is a general purpose skim fitted as standard to all Dowdeswell ploughs up to the DF 105. Suitable for work on grassland or stubble, the ’K’ copes well with trashy conditions and can be used also at a wide range of furrow widths.

Round Stalk ‘J’ Type Skim

Developed originally for use with crawler ploughs, the ‘J’ skim uses the same point and wing as the ‘K’ but has a 20º  flatter working angle giving it good soil flow characteristics at slower forward speeds and in heavy soils.

Dowdeswell plough disc coulterDisc Coulters

Available as an option, disc coulters are still specified on the rearmost furrow of more than 90 per cent of the ploughs supplied by Dowdeswell.
The purpose of the rear disc is to leave a clean cut vertical furrow wall to assist the driver on the subsequent pass across the field.
A choice of plain or cutaway discs can be specified, the latter being better suited to cutting through surface trash and vegetation, particularly when working close to hedges when ploughing out the headland.

Knife Coulter on a Dowdeswell ploughKnife Coulter

Option - £25 per pair
Bolted between the point and the wing, knife coulters are a lower cost and lighter alternative to discs, being particularly suited for use in heavy land. In heavier soils, a knife coulter will produce a clean vertical cut between the furrows, eliminating lateral tear to help ensure that a constant furrow width is maintained. The cutting action through the soil of the knife coulter also reduces wear on the shin. They are not recommended for stony ground.

Trashboards on Dowdeswell ploughTrashboards

Option - Heavy land (curved) £63 per pair
Suitable for fitting to the top leading edge of all Dowdeswell bodies, trashboards are designed as an effective alternative to skims in heavy trash conditions. Removing the skim increases clearances between the bodies to minimise the risk of plough blockage. The trashboard prevents soil and other material riding over the mouldboard and diverts the top edge of the furrow and vegetation down into the turning furrow, layering trash between the furrow slices.  Trashboards work better in light land as their shape prevents effective scouring of heavy or clinging soils. Setting should be carried out in the field according to the ploughing depth and the level of surface residues.

Furrow splitter on a Dowdeswell ploughFurrow Splitter

Option - £27 per pair
Available for the DD, DDs and UCN/SCN bodies (when fitted with the small point option) the furrow splitter is used to slice the underside of the furrow as it turns allowing for better soil weathering. As the furrow splitter is bolted between the point and wing it requires very little downtime for replacement when compared with a weld on alternative.
Note: Knife Coulters and Furrow Splitters cannot be used together.

Subsoiler blade on a Dowdeswell ploughSubsoiler Blades

Option - £47 per pair (not available on YCN)
Primarily a heavy land accessory, the subsoiler blade is bolted to the side of the frog in place of the landside. Passing through the 6” of soil below maximum ploughing depth, the blade fractures and eases compaction beneath the mouldboard without bringing the subsoil to the surface. The number of subsoiler blades fitted to the plough is determined by the degree of compaction and the available tractor horsepower.  The resistance provided by four subsoiler blades is approximately equivalent to adding an extra furrow to the plough.

Furrow widener on a Dowdeswell ploughFurrow Wideners

Option - £168 per pair (state body type & tyre size when ordering)
Fitted to the rearmost body of the plough, the furrow widener breaks and removes the rear furrow wall to enable oversize tyres of up to 32” to be accommodated on the subsequent ploughing pass. The use of a furrow widener is advised when using a tractor fitted with tyres wider than 24” to prevent the wheels running on top of and compacting the previously turned final furrow. Furrow wideners are available in 6”, 8”, 10” and 12” widths to suit different sizes of tyre.

Tailpiece on a Dowdeswell ploughTail Pieces (DD & DD’S)

Option - £23 per pair
Used mainly on heavy ground, the tail piece is fitted to the outermost edge of the mouldboard and is used to close off the furrow if the mouldboard alone will not do so.  This is more common when ploughing speed is reduced and the turning furrow will not finish its turn under its own weight.
Tail pieces are included within the standard cost on UCN, SCN and YCN bodies.

Extra Underbeam Clearance

Option - £42 per pair (check for availability)
