Connecting Hydraulic Hoses - SaMASZ KDD 861 Operator's Manual

After the mower has been attached to tractor, check balance and steerability of tractor-mower
set. To do this, calculate to formulas given in the appendix or weigh the set, and then drive on the
scales only with front axis of the tractor (the mower must be in transport position – lifted upwards).
If the pressure on the front axis is at least 20 % of the whole set's pressure, it means the set is
stable. If not, front axis should be balanced.

WARNING!
To provide correct control of the machine when in operation, it is necessary to
enable the floating section of distributor which the main hydraulic system of
the machine is connected to.
5.1.1.1. Double-end disc mowers without swath conditioner/rollers and conveyors
In all mower models with own hydraulic assembly, to connect the mower to the tractor use
three hydraulic hoses: red – A, green – B and yellow – C (see label N-108 Fig. 14a). Hose A with
red connector is used for lifting of cutting units on headlands, for transport and unloading and for
setting pressure in support assembly. Hoses with green B and yellow C are used for lifting of
conveyors – right and left.
Connect each hose to a separate section of the tractor's external hydraulics (Fig. 14b). It
would be best, if the section would have a free oil flow. The tractor should have three pairs of
hydraulic connectors.
