Reducing your forward speed because of imprecise <\/span><b>row spacing<\/b><span style=\"font-weight: 400;\"> means wasting precious working hours, increased fuel consumption and the risk of damage to the plants.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It is therefore essential to ensure that the soil structure is compatible with the mechanical specifications of the harvester. The field layout must always be tailored to the dimensions of the machine: ensuring that the tyres or tracks run exactly in the centre of the row spacing allows the weight to be distributed evenly, thus preventing the crop from being trampled and minimizing soil compaction.<\/span><\/p>\n<h2><b>Technical design: bridging the gap between terrain and machinery<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">To avoid measurement errors and ensure that field work is coordinated as effectively as possible when a harvester is purchased or adjusted, it is important to clarify the terminology.

Inaccurate sizing undermines the harvester\u2019s potential and results in product waste that is unacceptable to the industrial supply chain.<\/span><\/p>\n<h3><b>Sizing the crop ridge<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The width of the <\/span><b>raised bed <\/b><span style=\"font-weight: 400;\">determines the usable cultivation area. In De Pietri\u2019s design philosophy, the width of the cutter bar is generally chosen to perfectly span the raised bed and corresponds to the machine\u2019s <\/span><b>track width<\/b><span style=\"font-weight: 400;\">. The aim is to make full use of 100% of the workspace:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 If the surface area of the raised bed is wider than the bar, the plants at the outer edges may be left out or end up with a ragged cut.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 If the raised bed is too narrow, the blade will cut through the furrows without making contact with the ground, with the risk of drawing soil or debris into the harvest bin.<\/span><\/li>\n<\/ul>\n<h3><b>Inter-row soil management<\/b><\/h3>\n<p><b>Inter-row spacing<\/b><span style=\"font-weight: 400;\"> is calculated by adding the width of the <\/span><b>raised crop bed<\/b><span style=\"font-weight: 400;\"> to the width of the adjacent wheel furrow. The width of the furrow varies, since it depends on the vehicle\u2019s footprint:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 <\/span><b>Tyres:<\/b><span style=\"font-weight: 400;\"> Require a margin of tolerance in the furrow to accommodate slight steering errors without running over the plants.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 <\/span><b>Tracks:<\/b><span style=\"font-weight: 400;\"> Guarantee flotation on soft soil, but need a well-levelled furrow to prevent the sides of the raised bed from being eroded.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Well-sized <\/span><b>row spacing<\/b><span style=\"font-weight: 400;\"> preserves the soil structure, protects the roots and ensures the self-propelled machine has the stability it needs for a consistent cut along the entire row.<\/span><\/p>\n<h2><b>Track width and wheelbase: De Pietri mechanics in action<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">While the size of the raised bed defines the working area, the structural parameters of the self-propelled harvester determine its fluidity of forward movement and overall manoeuvrability on the farm.<\/span><\/p>\n<h3><b>Optimization of track width<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">To ensure a smooth <\/span><b>mechanical harvest<\/b><span style=\"font-weight: 400;\"> the <\/span><b>track width<\/b><span style=\"font-weight: 400;\"> of your harvester must match the exact <\/span><b>distance between your crop rows<\/b><span style=\"font-weight: 400;\">. When this symmetry is perfect, the weight of the self-propelled machine is borne exclusively at the centre of the furrow. This prevents the side walls of the raised bed from collapsing, maintains the stability of the cutting mechanism and prevents delicate crops such as herbs or baby leaf from being trampled.<\/span><\/p>\n<h3><b>Wheelbase and headland calculation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The <\/span><b>wheelbase<\/b><span style=\"font-weight: 400;\"> plays a key role in weight distribution and the turning radius. A well-proportioned wheelbase ensures stability even at full load, but requires a suitable <\/span><b>headland<\/b><span style=\"font-weight: 400;\"> at the end of the field. The headland must be wide enough to allow the self-propelled harvester to exit the row completely, turn round and realign itself perfectly on the next bed without repeated manoeuvres.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Generally speaking, the minimum headland width is calculated by multiplying the machine\u2019s <\/span><b>wheelbase <\/b><span style=\"font-weight: 400;\">by a factor of between <\/span><b>1.5 and 2<\/b><span style=\"font-weight: 400;\">, to which the length of the harvesting header must be added. Ensuring a clear space of approximately <\/span><b>4 &#8211; 6 metres<\/b><span style=\"font-weight: 400;\"> allows for rapid manoeuvres, reduces downtime and eliminates the risk of collisions or damage to the ends of the crop beds.<\/span><\/p>\n<h2><b>Handy checklist: 4 steps prior to sowing<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Planning the field before the harvester arrives helps to avoid costly adjustments once the season is under way.<\/span><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 <\/span><b>Define the width of the raised crop bed:<\/b><span style=\"font-weight: 400;\"> Adjust the width and shape of the raised bed to match the harvester\u2019s cutting width so you use 100% of its capacity.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 <\/span><b>Calculate the space between rows:<\/b><span style=\"font-weight: 400;\"> Add to the width of the raised bed the clearance required for the drive mechanisms (tyres or tracks) to pass through the centre of the furrow.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 <\/span><b>Mark out the headland:<\/b><span style=\"font-weight: 400;\"> Leave a clear space at the end of the field proportionate to the <\/span><b>wheelbase<\/b><span style=\"font-weight: 400;\"> of the harvester (indicatively between 4 and 6 metres), to ensure smooth manoeuvres.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> \u00a0 \u00a0 <\/span><b>Check the track width of the machine:<\/b><span style=\"font-weight: 400;\"> Make sure that the <\/span><b>track width<\/b><span style=\"font-weight: 400;\"> of the machine matches the <\/span><b>row spacing<\/b><span style=\"font-weight: 400;\"> exactly before proceeding with the plotting and sowing operations.<\/span><\/li>\n<\/ol>\n<h2><b>Frequently asked questions about field preparation<\/b><\/h2>\n<p><b>What happens if the row spacing fails to match the harvester\u2019s track width?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A misalignment will cause the wheelwork to run along the edges of the raised bed.
