4. 6 EQUIPMENT MATCHING

The Walinga Agri-Vac® is designed to be used with Agricultural tractors/power units. To insure a good
performance, the following list of specifications must be met:
1. Horsepower: (Table 1)
Use Table 1 as a guide in determining the minimum recommended horsepower for different
models.
2. Drawbar Dimensions: (Fig. 4-4)
The tractor drawbar dimension must be 16 inches between the end of the shaft and drawbar pin
hole center for the 1000 RPM model and 14 inches for the 540 RPM model. This will provide
sufficient clearance for turning and allow telescoping of the shaft. Consult your tractor manual for the
drawbar adjustment procedure.

3. PTO Shaft:
The tractor PTO shaft must meet these specifications:
540 RPM - 6 spline, 1 3/8 inch dia.
1000 RPM - 21 spline, 1 3/8 inch dia, 21 spline, or 1-3/4 for 180 hp tractors.
It is not recommended that shaft adaptors be used on the tractor shaft to prevent operating
at the wrong RPM. Use extra care when using a tractor with a shift able PTO speed.
Operating a 540 PTO machine with 1000 PTO can cause serious damage to blower and
possible personal injury. It also voids the warranty.
4. Hydraulic System:
The power unit must have one remote hydraulic valve to operate the airlock hydraulic motor
and one to operate the boom lift circuit. The system must be capable of 15 gpm (56 lpm) @ 1500
psi (10,300 kPa). Either closed-centre or open-centered system can be used.
