Connection

Stabilization struts/support struts on tractors must be used.

This is to ensure that the snow blower does not get uncontrolled lateral movements while

driving – i.e. goes in the same direction as the tractor all the times.

Make sure no one is standing between the tractor and the machine during connection. Back the

tractor up to the snow blower and stop the engine before the lifting arms are mounted in the three-

point hitch.

Hydraulic hoses installation. At the same time, check that all hoses are tight and undamaged

before starting hydraulic functions. When the tractor engine is stopped, you should ensure that

there is no pressure in the hoses by activating the tractor's hydraulic valves.

Pay special attention to the dangers of hydraulic oil under pressure.

Install the power transmission shaft on the PTO with the shear - bolt coupling against the snow

blower. A safety chain is attached to the snow blower to prevent the rotation of protective covers.

The power transmission shaft must always have a shear bolt coupling max 4180 nm.

Make sure that the protective covers for the power transmission shaft are unaffected(undamaged)

and replace them if they are damaged.

Before connecting the power transmission shaft, secure the following points.

Make sure that the shaft's protective tubes are unaffected(undamaged) and that the two halves of

the shaft fit freely into each other. The length of the power transmission shafts must be adjusted

carefully, if it is too long it can damage the bearing in the tractor's PTO or the snow blower's

bearings. Also ensure good lubrication of the profile pipes. See also the instruction manual for the

power transmission shaft.

Check that the power transmission shaft can be rotated by hand to ensure that it is not buckling

anywhere.

Check that the power transmission shaft will not be tensioned when the machine is lifted to max.

or min. height. Driving on very hilly relief, a rear-mounted snow blower can work lower or higher

than the tractor itself. Please also note that the angle of the axle can be too large when using very

short axles - contact the supplier - importer.
