6.9.2 Tractor Towing Size Requirements
Use the following charts to help calculate the minimum tractor weight when towing without implement brakes. The
minimum tractor weight, up to 20 mph (33 kph) needs to be two thirds of the box Gross Weight (GW). Gross Weight is
calculated by the empty weight of the box and undercarriage combined added to the Load Weight. Then take the Gross
Weight and multiply it by 0.667 and you will get the Minimum Required Weight of the Tractor.
Spreader Loaded Weight x .667 = Minimum Tractor Weight Up to 20 mph
6.9.3 Spreader Brake Information (Optional)
Two optional brake systems are offered for your spreader. A brake system is recommended for any spreader operated on
public roads and may be a requirement.
6.9.3.1 Lever Operated Hydraulic Bakes
This brake system is connected to the tractor remote hydraulic ports and is controlled by the tractor hydraulic system. The
two hose system has a hydraulic manifold with pressure relief to prevent the pressure to the brake activating cylinders to
exceed the relief valve setting.
Applying hydraulic pressure from the tractor causes tractor hydraulic fluid to flow under pressure to the pressure relief
valve and activates the brake activating cylinders to apply the brakes.
Applying The Brakes - Gradually move the tractor spool valve lever as required to apply the brake. The hydraulic
hoses should be connected to the tractor ports so the spool valve lever gives the expected response. Test this after
hooking up. If response is opposite of expected, reverse the hoses.
Releasing The Brakes - Move the tractor spool valve lever to the opposite direction and hold momentarily. Then
return lever to the “float” position.
NOTE: Simply returning the spool valve lever to the neutral position without first moving the lever to the opposite
position will not release the brakes.
6.9.3.2 Pedal Operated Hydraulic Bakes
This brake system is a one hose system. The single hydraulic hose must be connected to the tractor remote pedal port.
Applying The Brakes - Gradually apply the tractor brake pedal to apply the brakes.
Releasing The Brakes - Release the tractor brake pedal to release the brakes.

When brakes are not required, the spool valve lever must be in the
“float” position on the tractor spool valve.
At no time should the brake system be used as a parking brake. With
loss of hydraulic pressure, the brakes will lose their holding power.
