Valley Tool Vrisimo Sanitizer, Manual

Basic Operation 

Attaching  to the Power Unit 

Note:

When you ordered your Vrisimo A achment, 

details about your Power Unit were provided to custom 
match your A achment to your Power Unit.  While Vri-
simo A achments can be a ached to a variety of 
different tractors, your A achment is specifically con-
figured for your Power Unit and can not necessarily be 
placed on another Power Unit as is.  Specifically, the 
mount category and gearbox/pulley were selected to 
mate to your Power Unit’s hitch and op mize perfor-
mance based on your PTO output, respec vely.  Your 
A achment should only be connected to Power Units 
that share the same specifica ons as the informa on 
on the Power Unit you provided.  A achment instruc-

ons are for the most common configura on: 3-point 

hitch with a PTO output of 540 rpm. 

The person that is a aching your Vrisimo prod‐

uct should be familiar with the a achment and remov‐
al of equipment from a 3‐point hitch and be able to do 
so safely.  A achment should be performed on flat 
ground away from obstruc ons.  During a achment, 
keep hands out of pinch points and away from the 
blades to avoid injury. 

The tractor’s drawbar should be placed to its 

shortest point, if there is s ll insufficient clearance 
then it should be removed.  If your tractor has load 
and depth control, lock out control so it will not func‐

on but be in “free float.” 

1)  Back the tractor up to the front of the machine so 

that the li  links are in line with the mower’s hitch 
pins. 

2)  Shut off the engine and disengage the PTO.  Block 

the tractor’s wheels before placing yourself be‐
tween the tractor and the a achment. 

3)  A ach the tractor’s le  and right li  links to the 

corresponding hitch pins of the a achment, secur 

 
 
ing both connec ons with lynch pins. 

4)   Adjust the sway bars so that there is a minimum 

side slack and be sure the stabilizers are  ght. 

5)  A ach the tractor’s top link to the “A” frame of the 

a achment and adjust the top link to the approxi‐
mate desired cu ng height. 

6)  A ach the PTO to the tractor by  pushing in on the 

quick disconnect pin.  Remember, the tube end 
goes to the a achment and the bar end goes to 
the tractor. 

7)  With the a achment and PTO line connected check 

the drive sha  through the en re li ing range 
checking for binding, bo oming, uncoupling or 
a achment contact. 

Starting Procedure

The Operator should be properly trained on the 

use of your Vrisimo A achment and wearing the ap‐
propriate safety gear.  Do not start the Power Unit un‐

l the A achment has been checked for proper assem‐

bly and installa on.  This includes the appropriate con‐
nec on of the hitch and PTO connec ons as well as 
the proper func oning of all safety devices on both the 
Power Unit and the A achment.  Clear the work area 
of all bystanders and children: 

1)  Check that the a achment is in the down posi on 

and that the blades are not in contact with ground.  
Start engine and set thro le to idle.  Never engage 
the PTO with the motor above idle speed.
