Kubota CU3001 Series
On modern farms, cultivation demands have changed. Tight time slots have to be balanced with higher machine performance. Restricted crop rotations call for technology that meets all the requirements of complex cultivation. Kubota’s CU3001 Series Tine Cultivators offer powerful and efficient performance at high forward speeds and consistent working depth. The CU3001 Series has a well-organised tine arrangement over 3 rows with 285 mm spacing that is designed to ensure smooth flow, optimal mixing and intensive seedbed cultivation even with long residues.
Strong Frame
The CU3001 Series frame is a result of a long study made by FEM (Finite Element Method) calculation to optimise the steel over the working width and find a strong structure suitable for tractors up to 350 hp. The CU3001 range has been designed to combine with even the heaviest rollers. All the most aggressive work scenarios (deep turn work, headland turns, transport) have been tested to ensure the cultivator frames are strong and reliable, as you’d expect from Kubota.
Tines and Shares
The Auto-Reset TriFlex tine uses Kubota’s well-known leaf spring system to ensure a high point pressure of 700 kg and smooth release curve in case the tine hits an obstacle. The heat-treated tines are narrow, with two working zones to reduce pulling force while ensuring penetration even in heavily compacted soil. The CU3001 Series is the perfect choice for deep loosening and working on heavier soil types with stones. TriFlex tines can be equipped with different shares to adapt to working depths and tasks. Seven share design options are available with the Knock-on system, providing the easiest way to change parts on a cultivator for the next task or maintenance.
Tine Deflectors
The CU3001 Series comes standard with straight deflectors fitted to the tine leg. The deflectors are designed to roll the soil for optimum mixing of residues, and avoid topside residue accumulation.
Depth Control
Depth control for the CU3001 is achieved via 2 double acting hydraulic cylinders with spacers. The spacers are easily adjusted to set the perfect working depth.
Versatile Rear Rollers
A range of roller options provide versatility. The 550 mm diameter cage roller (weighing 90 kg/m) has 10 bars for excellent loading capacity and effective crumbling in wet conditions. The 565 mm Actipack roller (220 kg/m) provides superb working qualities on medium to heavy soils and in wet, stony or sticky conditions thanks to the independent skids and knives. The cutting discs break the larger clods while the adjustable knives cut what remains, resulting in optimal breakdown and fine seedbed preparation.
