OPERATION
OPERATION
THE GEARBOX AND TRANSMISSION ARE SHIPPED WITH-
OUT OIL.
ADD OIL BEFORE FIRST USE!
Gear Oil SAE90 2200ml (approx. 2.3 US Quarts)
Check oil level in gearbox by removing the plug located on
the right-hand side. Oil should be level with bottom of plug
hole. Add oil if necessary, by removing top fill plug and side
plug. Add oil until it flows from side plug hole.
PTO shaft with chosen gear ratio, max. 540 RPM.
Three-point hitch of I category.
The model MECHMAXX TSG61 requires a tractor of at
least 20 hp or up to a maximum of 60 hp.
Maximum number of revolutions and direction of tractor
PTO shaft rotation is 540 rpm/min.
Length of PTO shaft needs to be adjusted for different
tractors (figure F1-F4).
Ascertain the accurate length in the following manner:
1.Shut down the tractor.
2.Connect the machine to the tractor.
3.Extract the PTO shaft apart and connect the individual
shaft halves to the tractor and machine and compare
them crosswise and mark them (figure F1).
4.Shorten external and internal plastic plastic shield
tubes (figure F2).
5.Shorten external and internal slide profiles by the same
amount as plastic plastic shield tubes (figure F3).
6. Deburr the cut ends of both the inner and outer profiles,
remove any filings, and thoroughly grease the sliding
surfaces (figure F4).
Do not overfill!
IMPORTANT: Implements should be level when checking
oil in gearbox!

OPERATION
When connecting the winch, do not stand in the danger
zone!
The forestry winch can be attached to every tractor with
a three-point hitch with a category I coupling. Appropriate
construction also enables easy connection to the tractor
with automatic connection rods. Connect the prescribed
PTO shaft and secure cardan protection with a hang
chain.
Be careful that the cardan clicks into place on both
connection points!
Once the winch is attached to the tractor, strengthen the
stabilizers on the lower connection rods and level the
winch with a hitch nut into position, so that the winch is
tilted backwards for approximately 20 degrees.
The cutting height should be 0.5"-1.25". we think the
customer cutting more than 1.25", that makes grinder
working slowly.
The grinder should work from right to left or left to right.
grinder parallel not vertical.
When the attachment has completed a pass, move it
rearward about 0.5“-1.25” and engage the control to cut
back across in the opposite direction. Never directly up to
down.
Operate the cutting wheel at 540 rpm (speed while under
no load).
The cutting wheel feed is controlled by the hydraulic cylin-
der and the pressure control valve.
The rate of cut will depend on the type of tree, condition
of the wood, and the condition of the carbide cutting
teeth.
Excessive feed rates will either stall the engine or slip the
clutch.
Too light a feed will produce sawdust.
Please adjust the two speed flow valves in the cylinders
by a suitable level depend on your tractor, ensure swing
cylinder make the arm by smooth/ and slow moving from
right to left. NEVER use high speed in cylinder /arm swing
moving.
