(2) Vertical, Water-Cooled, 4-Cylinder Diesel Engine Model V 1200-A engine has a reserved power. Torque output is high from low to high speeds. The 4 - cylinder engine distributes the combustion pattern for smooth, low-vibration operation. Glow plugs for cold weather starting are standard. (3) Transmission The automatic hydrostatic transmission. With a fixed engine speed, tractor speed can be chosen freely while maintaining forward and reverse. Also this tractor has 3 speed range transmission. (4) Brakes large brakes provide positive, effortless stopping power. Brakes can be depressed and then secured with a locking lever to act as a parking brake. (5) Spring-Suspended Bucket Seat High efficiency spring suspension absorbs ground shock and reduces fatigue. "One-Touch" lever control adjusts seat over a range of 60 mm (2.36 in.). The seat locks into 4 different positions by 20 mm (0.79 in.). (6) New Power-Torque Tires New open lug pattern assures a better bite on the ground for increased traction force. Stability is substantially improved under any ground conditions. Turf tires are square type that least wound the lawn. (7) Hydraulic Pump This hydraulic pump provides high efficiency to all hydraulic powered implements. Hydraulic pump capacity is 27 g , min. ( 7.1 U.s. GPM, 5.9 Imp. GPM) (8) Hydraulic Block Type Outlet Hydraulic block type outlet feeds oil in three directions. • To front-mounted implements (front loader, etc.) • To power steering • To rear-mounted implements (9) Position Control Valve This position control valve has a shockless mechanism for smooth and comfortable operation or three point hydraulic system.

With KUBOTA's spherical combustion chamber, well-known Bosch K type injection pump and the well-balanced designs, they give greater power, low fuel consumption, little vibration and quiet operation.

M.l ENGINE B9200HST WSM,60339-0 [2] ENGINE BODY (1) Cylinder Block i 0107FOll ~------- (2) Cylinder Head The engine has a high durability tunnel-type cylinder in which the crankshaft bearing part is constructed in a body. Furthermore, dry-type cylinder liners, being pressure-fitted into cylinders, allow effective cooling, less distortion, and greater wear- resistance_ The noise level is reduced to a minimum because each cylinder has its own chamber. The cross-flow type inlet/exhaust ports in this engine have their openings at both sides of the cylinder head. Because overlaps of inlet/exhaust ports are smaller than in ports of other types which have openings on one side, the suction air can be protected from being heated and expanded by heated exhaust air. The cool, high density suction air has high volume efficiency and raises the power of the engine. Furthermore, distortion of the cylinder head by heated exhaust air is reduced because suction ports are arranged alternately. The combustion chamber is of KUBOTA's exclusive spherical combustion chamber type. Suction air is whirled to be mixed effectively with fuel, prompting combustion and reducing fuel consumption. In the combustion chamber are installed throttle type injection nozzle and rapid heating sheathed type glow plug. This glow plug assures easier than ever engine starts even at -15°( (5°F). 0107F012 0011F013 (1) Combustion Chamber (4) Nozzle Assembly (2) Suction (S) Glow Plug (3) Exhaust (6) Cylinder Head M.1-2

It also drives the oil pump, camshaft and fuel camshaft. Eight counterweights, which are cast together with the crankshaft, prevent a large force of inertia from partially working on the crankshaft, consequently reducing the wear of the crankshaft bearings and lessening the temperature rise of the lubricating oil. Crankshaft journals, crankpins and oil seal sliding section are induction-hardened to increase wear (5) Crankshaft Bearing 2 (6) Thrust Beanng resi stance. Crankshaft journals are supported by the main bearing cases in which a bearing is used. Crankshaft bearing 1 (3) at the front end is a solid type bushing and the four bearings 2 (5) behind are split type. Thrust bearings (6) are mounted on both sides of the main bearing case at the flywheel side. Cranksha ft bearings and thrust beari ngs are plated with a special alloy to raise wear resistance quality. Furthermore the crankshaft, crankshaft bearings and main bearing cases have oil holes.

M.l ENGINE B9200HST WSM,60339-0 (4) Piston and Piston Ring 0107F015 0107F031 Piston circumference has a special elliptic shape in consideration of expansion due to explosion heat. Piston head is flatformed. Grooves are cut round the top section of the piston. These grooves help to dissipate heat and prevent scuffing. Piston (5) is made of special aluminum alloy of low thermal expansion and high temperature resistance. Compression ring 1 (1) is of the key stone type which can stand against heavy load, and the sliding surface to the cylinder wall is shaped into barrel face which is well fitted to the wall and plated with hard chrome. Compression ring 2 (2) is of the under-cut type which is effective to prevent oil rising. Oil ring (3) is effective to scrape oil because it is closely fitted to the cylinder wall by a coil expander and the upper and lower ends of its sliding surface are cut diagonally to raise face pressure to the cylinder walls. Some scraped oil is forced into the inside of piston through the oil escape holes of rings and piston. The oil ring is plated with hard chrome to increase wear resistance quality. • IMPORTANT • Note that the piston 2's (8) in the No.2 and No.3 cylinders have different profile from the pistons (1) in the No.1 and No.4 cylinders. The piston 2 (8) is marked "2" on the head. Be sure to install the pistons (1) (8) to each original cylinders. Name ..................

The journal sections are force-lubricated. The fuel camshaft (12) controls the reciprocating movement of the injection pump, and is equipped with a ball to control the governor. The fuel camshaft is made of carbon steel and the cam sections are quenched and tempered to provide greater wear resistance.
