PTO Pump
One of four dealer- or field-installed kits enable the fan,
or the fan and hydraulic meter drive, to be driven from a
tractor Power Take-Off (PTO), rather than dedicated
continuous flow tractor hydraulic remote(s).
Each Air-Pro
®
PTO Pump kit includes:
• a flow control valve assembly for setting fan rpm,
• a tethered PTO pump for a “live” or “independent”
rear-facing stub. The pump includes torque arm and
safety chain (no gearbox is required),
• an oil reservoir, with sight gauge, line filter and
6.5 gallon capacity (5.5 gallons/21 liters used),
• an oil cooler, mounted inside the fan, and;
• all interconnecting hoses (not shown).
There are separate kits for 540 rpm and 1000 rpm PTO,
and for planters with ground or hydraulic seed meter
drive.
The 540 rpm kits couple directly to an ASABE or ASAE
Type 1 6-spline 1
3 ⁄
8
inch (35 mm) shaft.
The 1000 rpm kits require separate purchase of a
coupler to adapt them to an ASABE or ASAE:
Type 2 20-spline 1
3 ⁄
4
inch (44.5 mm) or
Type 3 21-spline 1
3 ⁄
8
inch (35 mm) shaft.
One kit updates one planter.
Suitable Applications
A PTO kit may be needed where:
• the tractor has an Open Center hydraulic system;
• the tractor has no remote port for the fan; or,
• the tractor is Closed Center, but the remotes offer
insufficient oil flow to reliably operate the fan.
