Tillage is the process of working the soil structure to prepare it for sowing, improve germination and seed growth, control pests, improve water and air supply to keep crops viable, and suppress or destroy weeds.
Year after year, whatever the type of implement, any tillage operation leaves a so-called plough pan, formed by the repeated passes of agricultural machinery across the field.
The FraMest Inverta mounted subsoiler is a primary tillage implement working to a depth of 70 cm (deep loosening), more than enough to break up 100% of the plough pan formed by tilling at the same depth over a long period (ploughing/discing).
This tillage improves soil aeration and water infiltration and promotes better root development.
The implement is available in 3 m (for 300–360 hp tractors) and 4 m (for tractors over 400 hp) working widths.
Consistent working depth. The depth indicator lets the operator monitor the working depth continuously, and the depth can be changed when needed without leaving the tractor cab.
Double spiked roller with optimum ground pressure. Breaks up the clods left behind the tines. The roller teeth are arranged in a spiral to reduce blockage (wrapping) by crop residue. The roller is hydraulically adjustable.
The highest underframe clearance on the market.
The share is bolted to the leg. This acts as an additional protection system for the load-bearing frame. Flexible leg layout: the number of legs and the spacing between them can be changed. The design also protects against side loads.
Parallelogram-mounted roller. The parallelogram linkage keeps the front and rear rollers parallel to the ground at all times.
Hydraulic roller adjustment as standard.
Side wings on the shares for better soil fracturing and mixing. The tines are designed to protect the leg from wear as much as possible.
86 cm spacing between tines. This keeps soil flowing freely between the tines without blockage, even in heavy crop residue. The tines are protected by a shear bolt.
Deep loosening improves air and water exchange in the soil and helps plants root quickly, thanks to the Inverta tine: a leg carrying an angled chisel point. It can be used in any conditions without the risk of forming a plough pan.
Side deflectors on both sides of the implement keep soil and clods within the working width, where the roller then breaks them up.
FraMest builds its agricultural implements exclusively from top-quality British steel supplied by British Steel. The design and shape of the parts made for the Inverta subsoiler optimise the tractor power requirement and guarantee high-quality tillage in the most difficult conditions. Genuine spare parts help reduce the cost of wearing parts.
