The velocity diagram of “BELARUS-952.5” tractor equipped with double-lever GB control and
reverse gear unit on tires of basic configuration is the same as the velocity diagram of
“BELARUS-952.5” tractor equipped with single-lever GB and reverse gear unit shown in figure
2.14.7.
2.14.5 Gears shifting in the transmission with a single-lever GB control and reverse gear
unit
The gears are set by two levers: lever to shift ranges and gears of gearbox 3 (figure 2.14.6)
and control lever of the reverse gear unit 1.
The required ranges, gears and passes of the reverse gear unit (forward motion pass – symbol
"forward", reverse motion pass – symbol "reverse") are set as per the scheme 4 and 2 as it is
shown in Figure 2.14.6.
Gearbox ranges and gears are shifted by one lever 3, first set the range (the I-st or the II-nd),
then set lever in a position «N», so you engage a required gear.
During tractor operation the control lever of the reverse gear unit 1 shall be in switched-on
position (fixed): forward – forward motion pass (“forward”), or reverse – reverse motion pass
(“reverse”). It’s allowed to hold the control lever of the reverse gear unit in a neutral position
(middle, non-fixed) to make easier the engine start at low temperature.
1 – control lever of the reverse gear unit; 2 – diagram of passes shifting of the reverse gear unit;
3 – lever to shift ranges and gears of the GB; 4 – diagram of GB ranges and gears shifting.
