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 linkage, or is automatically connected to quick coupling HMV or triangle.

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 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 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.
