becomes Gear 1 with the gearshift lever being on the right side. It is necessary to turn the gearshift lever so that it points to the
rear of the machine toward the operator. This can be done so that the safety split pin is taken out, the gearshift lever is pulled
out from the square journal and re-installed onto the journal in the new position (pointing to the operator) and secured once
again with the safety split pin.

USING GEARBOX MODEL T-20 A: Gearbox T-20 A can be used for working with VARI-System implements. If there is a
towing axle mounted on the gear case, the result is a single-axle tractor. Wheels have free wheel hubs with a spring-loaded free
wheel finger to enable four free wheel positions. Finger positions are illustrated in Fig. 7.

Free wheel finger positions
POSITION LOCKED: at this position the wheel is firmly connected with the hub. Finger linkage tip points either into the
wheel centre or from the wheel centre out. The position serves for straight travel forward or back. Turning the machine set at
this position is however difficult.
POSITION FREE RUNNING FORWARD: at this position of the finger with the wheel turning forward the wheel is firmly
connected with the hub. When the wheel turns back or in the situation when the wheel turns faster than the axle, angular plane
on the finger will enable the finger to jump out from the incision in the hub, which is indicated by a clapping sound. Finger
