Kirovets K744 - Overview

__________________________________________

For the broadacre farmer, a large and powerful tractor is an essential piece of capital equipment. Choosing the right machine requires careful technical and economic analysis. Will it do the job? How much does it cost? Is it reliable? Is the service and spares support prompt and dependable? Will it last a long time?

 

Productive

Kirovets tractors deliver real productivity gains. They cost much less to buy and much less to run than competitors. They

have efficient engines and drivetrains, simple and straightforward maintenance requirements and low cost service and replacement parts.

 

Tough

Kirovets tractors are designed to work under the world’s toughest conditions. They have solid construction, powerful engines and a robust drivetrain. Engineered to handle the big loads, a Kirovets is built to last.

 

Useful

A Kirovets can handle any job. A floating drawbar and a cat. IV three point linkage with Walterscheid lower links are fitted as standard equipment. Duals and a 1000 rpm 44.45mm x 20 spline PTO are optional extras. Bosch Rexroth 180 l/min hydraulics are standard.

Engines

 

The standard engine is the Tutayevsky 8481. These large capacity (17.24 litre) Russian built V8 turbo-diesels have cast iron blocks with replaceable wet cylinder liners. The eight separate four-valve aluminium cylinder heads enable combustion space optimisation during assembly. Inlet and exhaust valves are actuated by forked rockers and roller tappets. Oil-cooled Mahle-type silicon alloy pistons are used, joined to a

nitride-hardened cross-plane crankshaft by steel connecting rods.

 

Proven in transport, off-road racing, marine and military applications, these are basic mechanical injection designs offering robustness, exceptional reliability, ease of maintenance and a long service life. Fuel consumption is 213 g/kW/hr.

 

The premium engine offered is the 12.82 litre Mercedes Benz OM 460 LA. This is an in-line six cylinder turbo-diesel with electronic engine management for superior fuel economy and emissions performance. The engines are configured to Euro IIIA standard and do not require the use of DEF fluid or a DPF. These heavy-duty German built engines have a noise optimised cast iron block with wet cylinder liners, a cast iron single piece cylinder head, oil-cooled aluminium pistons, precision forged connecting rods and a seven bearing crankshaft. The oil cooler is integrated within the crankcase.

 

These engines offer exceptional durability and fuel economy (205 g/kW/hr), proven throughout the world in many civil, military, marine, agricultural and transportation equipment applications.

 

Engine air supply is cleaned through a two-stage cyclonic filter with elevated intake and an exhaust bypass. Access to the filter cartridge for purging or replacement is at ground level.

 

A large capacity fuel tank is mounted on the rear frame element. Capacity is 800 litres; enough to sustain the longest working shift.

Transmission

 

Kirovets tractors use a constant mesh transmission with sixteen forward and eight reverse speeds in four ranges. Within each range, speeds can be selected under power without interruption by hydraulically energising the appropriate clutch pack; a multi-disc assembly with alternating steel and ceramic plates.

 

Ranges are engaged by axially sliding sleeve gears on the middle and bottom shafts. Gear and range selection is electronically actuated from the dashboard console using pneumatic actuators.

 

The transmission is pressure lubricated and has a front mounted oil cooler. The design is thoroughly proven, simple, robust and durable. Spur gears are used throughout for strength, power transmission efficiency and the elimination of axial thrust loads within the transmission casing.

 

All gear wheels are hobbed and milled from billet on Siemens CNC gear-cutting machines. After heat treatment, tooth profiles are finish ground to precise final dimensions and geometry. Transmissions are hand assembled by master technicians and thoroughly bench tested prior to installation on the tractor frame.

 

Frame

 

The frame provides the structural platform of the tractor; a mounting for all of its power generating, transmitting and controlling parts.

 

With ballast and a full fuel load, a Kirovets can weigh close to twenty tonnes. The frame needs to be strong enough to support the mechanical parts and absorb all working loads, whether imposed by towed or attached implements or by difficult terrain.

 

The frame must be built to endure, without failure or fatigue, a working life that may easily extend to more than forty years.

 

The Kirovets frame is a solidly made all-enclosed box section steel weldment. Frame parts are cut and folded, assembled, carefully welded and precision machined. A massive centre pivot articulates the front and rear parts of the frame through a trunnion yoke with large, fully sealed, bearing surfaces.

 

This yoke provides for relative movement of the front and rear frame elements with two degrees of freedom; +/-320 on the vertical axis and +/-160 on the longitudinal axis. It is this design feature that gives articulated tractors their advantageous characteristics; the ability to maintain all-wheel ground contact on undulating terrain, a compact turn radius and a steering geometry that, unlike fixed-frame front wheel steered machines, ensures that the leading and trailing wheels follow the same path.

 

Suspension

 

When the initial design brief for the first big Kirovets was drawn up over fifty years ago, a requirement was that the machine be able to perform a wide range of tasks.

 

Apart from its prime agricultural function, a Kirovets was expected to be capable of performing on and off road transportation tasks and serve as a military tractor if required. To reduce operator fatigue when used on the most arduous terrain, the design team included a truck-type cantilever

laminated spring front suspension with hydraulic shock absorbers.

 

This feature has carried forward in all subsequent design iterations and provides for a more comfortable ride than conventional, unsuspended, designs.

 

Axles

 

Power is transmitted via cardan shafts to the front and rear axles. Kirovets axles are of a unique "no-spin" design that lock in the straight ahead position to provide unsurpassed tractive performance.

 

Unlike other articulated tractors, the rear axle can be disengaged for smoother running in transport mode on hard surfaces. This feature makes the tractor much more competitive with FWA designs for a large range of tasks around the farm. Planetary gear

assemblies are mounted, together with air-assisted brakes, on the axle extremities.

 

The compact axle design allows wheels with wide, deep-section 800/65R32 low compaction tyres to be fitted. The tyres have an R1W tread pattern to enhance ride comfort. Dual wheels and spacers are available as an option.

 

The design of the transmission, axles and wheel set, taken together, provide Kirovets tractors with exceptional tractive efficiency.

 

Attachments

 

Equipment for mounting all types of implement is fitted to Kirovets as standard. Towed implements are attached by

a floating drawbar and attached implements by the

cat. IV 3-point linkage with Walterscheid lower links. EHR is available as an option.

 

Hydraulics are load sensing type with four pairs of outputs plus returns. The system is supplied by a Bosch-Rexroth A10VNO85 axial flow pump with 180 l/min capacity in basic specification.

 

A 1000 r/min PTO with 44.45 mm (1³/4") 20 spline output shaft is optional. Alternative output shaft configurations are available on request.

 

Cabin

 

The Kirovets cab is a highly functional, solidly built ROPs/FOPs structure. The cab is mounted and lined with vibration and noise insulation materials and glazed with solar-resistant glass. The cab is pressurised. Air-conditioning, heating, radio and fire extinguisher are standard.

 

The control column is adjustable for reach and height. A fully adjustable suspended seat and folding passenger seat are included, both with seatbelts.
