First on the market with a pto kit that lets you power pto implements off the front of your 4-wheel drive tractor is the Crary Co., Fargo, N. Dak.

"This kit enables you to use your 4-WD tractors on stationary applications, such as grain augers, silage blowers, generators, irrigation pumps and for short term dynamometer horsepower testing," reports Dave Majkrzak, vice president of engineering for the company. "With modifications on the implements, you can also use the pto for mobile applications, such as powering snow blowers and corn choppers."

"We're introducing kits to fit most popular big 4-WD tractors," Majkrzak adds. "Some tractor companies do have pto packages for the back of their tractors but this will give farmers who have tractors without pto's an alternative. Also, some farmers want a front pto to power a front; mounted implement."

Installation of the pto kit involves putting a 3% in. wide sprocket, 10 in. in dia., on the front of the crankshaft. If there isn't enough room for the sprocket, the fan will have to be extended and the shroud shortened.

A metal framework bolts to the frame of the tractors. Some tractors will have predrilled holes, others will require drilling of the bolt holes to bolt on the framework.

The sprocket with the 1,000 rpm shaft attaches to the framework, adjusting so the sprocket is in line with the pulley. A high horsepower cog belt slides over the two sprockets. The belt is capable of withstanding over 200 hp. at 1,000 rpm output speed.

An electric clutch engages the pto. The switch can be placed anywhere in the cab. On Steiger tractors for example, there is an empty switch that can be wired to the pto clutch. Crary provides decals that fit on the tachometer telling the pto speed. You'll need to check the manufacturer's recommended hp setting for operating the pto.

"It will take about 6 man hours to install the kit," Majkrzak notes. "But it'll take longer if you have to extend the fan and change the shroud."

Majkrzak adds that the pto sits higher than the rear drawbar on the tractor. If needed, the pto can be removed in less than an hour.

A front pto kit for a Steiger ST-225 sells for $3,275. Kits for other tractors are comparably priced. Rpm speeds other than 1,000 will also be available.
