Buhler 25 Series

25 Series Rotary Tiller

EQUIPMENT MATCHING

To insure the safe and reliable operation of the Tiller, it is necessary to use a tractor

with the correct specifications. Use the following list as a guide in selecting a tractor to

use on the machine.

1. Horsepower: Use Table 1 as a guide in selecting the tractor horsepower

appropriate for your width of machine. Use only small Agricultural tractors on this

machine.

Table 1 Horsepower vs. Width

Model Width Horsepower

40S 40 inches 18

(1.0m)

48S 4 feet 22

(1.3m)

60S 5 feet 25

(1.5m)

ALERT: Do not exceed the recommended horsepower levels. The use

of horsepower will void the warranty.

2. 3 Point Hitch:

The Tiller is equipped with a Category 1, 3 point hitch. Be sure the tractor 3 point

hitch is in the Category 1 configuration.

Install the lift arm blocks or shorten the stop chains to place the arms into the

non-sway configuration. Refer to the tractor manual for details.

3. Load Sensing Hydraulics:

Many newer tractors are equipped with "Load Sensing" hydraulics. It is the

responsibility of the operator to set the tractor hydraulic system to provide "float"

on the 3 point hitch.

The float feature will allow the machine to follow the ground contours during

operation.

4. PTO Shaft:

The tractor must have a 1 3/8" 6 spline 540 RPM PTO shaft to fit the driveline

shaft supplied with the machine. Do not use shaft adapters or operate at any

other speed.

It is not recommended that a tractor with variable speed PTO's be used on the

Tiller. Operating at speeds faster than 540 RPM will overload the drivetrain and

lead to early failures. Attach the safety chains supplied with the PTO shaft,

allowing sufficient slack for the Driveline during turns and operation. Check

booklet attached to the PTO for instructions.
