EQUIPMENT MATCHING

The Walinga Grain-Vac® is designed to be used with Agricultural tractors. To insure a good
performance, the following list of specifications must be met:
1. Horsepower: The 7614F Grain-Vac requires 120HP (90Kw)
2. Drawbar Dimensions: (Fig. 4-2)
The tractor drawbar dimension must be 16 inches between the end of the shaft and drawbar pin
hole center. 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:
1000 RPM - 21 spline, 1 3/8 inch diameter.
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.
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.
