Allmand TLB
GENERAL
The Allmand Allmand TLB heavy-duty, compact tractor-loader-backhoe is designed for its size
and maneuverability to excavate materials in areas that larger tractor-loader-backhoes can not
access. The front end loader is generally used for excavating, leveling, and for back filling
trenches and other types of excavations. The backhoe is generally used for excavation of soil
to form a trench or opening, depending upon operator’s needs, in areas where limited space is
a factor.
The base unit consists of a chassis, engine, hydrostatic transmission drive system, tires and
wheels, steering system, front end loader, hydraulic system, backhoe and Roll Over Protective
Structure (ROPS).
CHASSIS WITH INTEGRAL HYDRAULIC RESERVOIR
The chassis frame is constructed of formed steel and all components are welded in rigid fix-
tures to insure consistency of each part produced.
The hydraulic reservoir consists of the left and right vertical frame posts and the upper and
lower cross members. Provisions have been made in the reservoir for a 100 mesh suction
strainer, a 1-1/2" oil fill opening, Two 1/2" NPT magnetic drain plugs and oil level sight gauge.
The reservoir accomodates 10 gallons of hydraulic fluid and has room for the oil to expand.
The chassis includes mounting provisions for solid rear axle and drive plate, as well as the
oscillating front axle.
The chassis also includes mounting provisions for a certified ROPS which is attached with
specified hardware. The ROPS can be removed and replaced without affecting certification.
Refer to the proper section of this manual for instructions on this operation.
HYDROSTATIC TRANSMISSION DRIVE SYSTEM
The machine is driven by an infinitely variable hydrostatic transmission consisting of a variable
displacement pump and a fixed displacement motor. The pump unit includes a manual control
valve.
Control of the variable piston displacement pump is the key to controlling vehicle speed. Prime
mover horsepower is transmitted by the pump when the operator moves the directional control
pedal. When the variable piston pump swash plate is tilted, a positive stroke to the piston is
created.
