The Hagie model 470 is a 4 wheel drive hydrostatic, high clearance tractor capable of operating in a wide variety of row crop applications. The basic frame of the machine consists of a central chassis incorporating the engine, pumps and operator platform which is mounted on wheel assemblies that may be adjusted from a tread width of 60 to 80 inches. The front axle pivots around the chassis' central axis and is tied to the rear axle via parallel links, this allows for extreme flexibility for following uneven terrain and gives it exceptional stability for its height. Weighing in at about 3600 lbs. the Hagie 470 carries 2400 on the rear axle and 1200 on the front. The frame has a row crop clearance of 72" and a 58" belly clearance below a 26" wide chassis. The drive train employs a German
built V4 Ford Industrial gasoline engine (OHV, 104 ci, water cooled) rated 48
horsepower at 2950 rpm governed speed. A Cessna (Eaton) 70442 5000psi hydrostatic pump (2.48
cir axial piston, variable displacement type) is directly splined to the engine. Four
Cessna 74118 wheel motors (1.24 cir axial piston, fixed displacement) drive 11.2 x
24 wheels through 30:1 ratio Fairfield planetary hubs (some earlier models use 7.5 x 20
wheels and 18:1 planetaries on the front axle). In 4WD mode the Hagie 470 has a top
speed of about 5 mph, increasing to 10-11 in 2WD. A Cessna 24335 gear pump supplies
steering and auxiliary hydraulic power with most units able to supply at least 6 gpm of
auxiliary power at 1500 psi. When designing hydraulic systems, valving
and applications should be of the open center type.
The Hagie is primarily designed to carry personnel and/or equipment in a tall row
crop, crop bedding, nursery and vineyard setting. Out of stock. Contact Market Farm Implement |

| The Hagie model 473 is a full time 4 wheel drive hydrostatic, high
clearance tractor capable of operating in a wide variety of row crop applications. The
basic frame of the machine is similar to, though slightly heavier than, the model 470
consisting of a central chassis incorporating the engine, pumps and operator platform
which is mounted on wheel assemblies that may be adjusted from a tread width of 60 to 80
inches. The front axle pivots around the chassis' central axis and is tied to the rear
axle via parallel links, this allows flexibility for following uneven terrain and gives it
exceptional stability for its height. The frame has a row crop clearance of 72"
and a 36" belly clearance below a 26" wide chassis. Belly clearance is
lower on the 473 due to larger drive train components requiring a repositioned fuel tank. The drive train employs a Chrysler 318
Industrial engine. A Sundstrand/Sauer 23 Series hydrostatic pump ( axial piston,
variable displacement type) is directly splined to the engine. Power is supplied
at the wheels by Series 15 and 18 Sundstrand wheel motors and 18:1 torque hubs. Like
the 470, the 473 rides on 11.2 x 24 tires. Auxiliary hydraulics are supplied by two
belt driven gear pumps. A Cessna (Eaton) 24335 gear pump supplies steering and auxiliary
hydraulic power with most units able to supply at least 6 gpm of auxiliary power at 1500
psi. A Cessna (Eaton) 24600-42C supplies additional circuits with many units
incorporating a 3 circuit rotary flow divider. When designing hydraulic
systems, valving and applications should be of the open center type. Performance and hydraulic capacity are improved over the 470
due to greater horse power, higher planetary ratios and more and larger pumps at the
sacrifice of fuel economy and belly clearance (row clearance is unchanged). Out of Stock. Contact Market Farm Implement |

The Hagie 8500 represents a radical departure from the 470 series chassis in that the
pivot has been moved to the rear axle and the upper parallel links have been
removed. This makes the tractor more user friendly in mounting and
dismounting. It would also simplify the fabrication of a cab enclosure since all
operator consoles are rigidly mounted with respect to the seat. The rear axle pivot
point has limited space in the chassis making the unit less flexible than the 470.
Fuel tankage has been moved to the left rear wheel stem thus preserving the tractor's
belly clearance. Tread width on the 8500 is adjustable from 64" to as much as
104" with some minor modifications to the fuel tank mounting. Belly clearance
under the 29" wide chassis is about 56". Row clearance is approximately
72". These units are equipped with a heavy duty hydraulic folding boom,
originally used for carrying cutter units or personnel. The boom spans 36 feet and
folds to 17 feet. It may also be manually reduced to 10 feet wide. The drive train is a four cylinder Chrysler 2.2L Industrial engine (135 cubic inch). A Sundstrand/Sauer M46 hydrostatic pump ( axial piston, variable displacement type) is directly splined to the engine. Drive mode is selectable between front wheel and four wheel drive with 18 series Sundstrand wheel motors driving the front wheels and 15 series on the rear. Like the 470 series the 8500 also rides on 11.2 x 24 tires driven by 18:1 torque hubs. A Cross gear pump supplies approximately 30 gpm of steering and auxiliary fluid power through a 3 circuit rotary flow divider. Two circuits of 10 gpm are available for auxiliary applications. When designing hydraulic systems, valving and applications should be of the open center type. Out of stock. Contact Market Farm Implement. |
