Gearbox
Serial Number
Q. Where do I find replacement parts?
R. First check your local tractor dealer and if they do not have parts, ask them to order
from the Vrisimo factory.
Q. How often should I change my knives?
R. Replacing the cutting knives is entirely up to the owner. When the cut begins to be in-
consistent or rough, consider replacing the knives. It is recommended to keep an extra
set of knives on hand so that loss of work time is minimal.
Q. How often should I replace my belts?
R. If you are experiencing repeated slipping or breaking of belts, try adjusting the level of
tension. If this does not remedy the problem, replace the belt. Consider having an ex-
tra belt on hand as well.
Q. Do I need to fill the gearbox with oil before I use the shredder?
R. No, the gearbox comes full with oil. Use 90 weight oil when replacing.
Q. What do I do if my belts are wearing out too fast or burning up?
R. First check belt tension. Belts should have about 3/8” sway in them. Adjust tension ac-
cordingly. If this does not help, check the height of the grass you are mowing. If the
grass is over 2 feet tall, you might have to adjust mower cutting height upwards and
slow the speed of your travel to reduce belt slippage.
Q. How can I prevent my PTO shaft from coming off during operation?
R. Be careful! Make sure the shaft is slid all the way on and the safety pin is in the locked
position.
