CREEPER (if installed)
Purpose and Scope of Application
The creeper is intended for installa-
tion on the tractors operated with the
machines requiring reduced speeds of
movements (reapers, snow ploughs,
crop collectors, etc.).
Using the creeper makes it possible
to reduce additionally the tractor speed
in four gears of the first range of the for-
ward and reverse movement each 4.5
times.
The calculated speeds of movement
of the tractor with the creeper engaged
are:
- in the forward movement: 0.384, 0.537,
0.738 and 1,01 km/h, respectively;
- in the reverse movement: 0.603, 0.844,
1.159, 1.587 km/h.
Should it be necessary to use the
gears of the first range of the forward
and reverse movement of the gearbox
with their rated gearing ratios, it would
be sufficient to disengage the creeper.
Construction and principle of opera-
tion
The creeper is an independent easily
removable assembly and designed as a
planetary spur-gear speed reducer to be
installed on the left of the gearbox (GB)
as seen in the direction of movement of
the tractor to provide the process range
of the tractor movement speeds.
