DP7D/2 4+1The Dowdeswell DP7 Auto turnover was a heavy duty range of fully mounted reversible ploughs with fixed furrow width suitable for tractors up to 260hp, working in the furrow only. Manufacured from 1979 to 2008 it is easily identifyable from the earlier cam-turnover model as the turnover ram is behind the headstock (viewed from the tractor). In the 30 years of manufacture there were many upgrades and improvments, When ordering spares knowing the serial number will help obtain the correct parts.

The DP7 was available in a Shearbolt model from 3 to 7 furrows and an Auto-Reset model from 3 to 5 furrows.

Turnover

Hydraulically operated with Auto Changeover Valve and independent adjustment for left and right hand verticality.

Alignment

Introduced in 1985 hydraulic adjustment of the plough alignment allows the front furrow width to be altered on the move from the tractor cab. Earlier models with turnbuckle adjustment can be modified to hydraulic ajustment.

Verticality

Screwed adjusters independently set the verticality left and right hand.

Headstock

Robust headstock with choice of top link and bottom link positions.

Offset

The main beam can be offset into different hole position to allow for different tractor wheel widths. See the instruction book & user guide in the download section for details of wheel widths.

Transport

The wheel converts for transport with the plough in the 'butterfly' position.(See Images)

Depth Control

Pneumatic depth wheel with independent adjustment and hydraulic damper for controlled turnover.

Auto-Reset

Auto-Reset models feature a mechanical system which benefits from the patented six ball pivot system and high point-lift capability, allowing bodies to trip sideways as well as vertically.

Dowdeswell UCN MouldboardUCN

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”)

SCN Bar Point

Has the same characteristics as the SCN body with the additional feature of a sprung loaded Bar Point for extra protection in difficult stone conditions.

 

Dowdeswell DD plough mouldboardDD

The DD was developed specifically to cater for a wide range of ploughing depths and widths.  It can work comfortably at 6” to 14” deep and at widths from 12” to 20”.  Of general purpose design, the DD has better scouring characteristics than the UCN and is suited also to work in lighter land at both shallower and deeper settings.  Dowdeswell DD plough wingThe DD’s design allows tyres of up to 24” wide to be accommodated within the furrow bottom – up to 4” greater than the UCN.
Point:  The DD has a small, single bolt, reversible point.
Wing:  Choice of a standard or wide wing is available.

Dowdeswell plough YCN mouldboardYCN

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”.

Dowdeswell plough slatted M-Slatt mouldboardM-SLATT

A specialist body with individually replaceable slats.  

Particularly suited to light-fluffy, sticky or peaty soils.  Suitable for work at depths from 5” to 12” and working widths from 12” to 18”.
Dowdeswell plough M-Slatt body reversible plough pointA reversible point is available as an after-sales item, which bolts over the existing non-reversible point.

 

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.

 

 

Round Stalk Skim

Standard fitting at the time most DP7's were being manufactured, mainly fitted with "K" type skims.

Round Stalk ‘K’ Type Skim

This is a general purpose skim fitted as standard to most Dowdeswell ploughs before the introduction of the Rectangulat skim. 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.

Rectangular Skim Stalks

Dowdeswell plough skim - rectangular stalk shape

Due to the popularity of the "Rectangular " skim when introduced on the DF 130 range a retrofit version was made available for older ploughs which were originally fitted with "Round" skims. This is attached using similar U-bolts to the round skim, no modification to the plough is required. The skim point and skim wing are interchangable from round to rectangular skims. The rectangular stalk benefits from having a pin and a series of holes for simple, spanner-less, depth adjustment..

Disc 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

Option - £25 per pair
Bolted to the side of the frog or 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
