The 300 Series can attach to tractor’s with either a CAT III or IV hitch. Refer to the tractor operator’s manual for the category of the tractor used. If the hitch does not conform to the ASABE CAT III or IV dimensions, the blade may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount nonconforming hitches.

Use the correct hitch pins for the hitch category being used. For a Cat III hitch, 1-1/8” lower and a 1” upper diameter hitch pins are used and Cat IV hitches require 1-7/16” lower and a 1-1/4” upper diameter hitch pins.

3.4 Front End Weight

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005

4. GETTING ON AND OFF THE TRACTOR

Before getting onto the tractor, the operator must read and completely understand the implement and tractor operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete explanation. OPS-U- 0007

Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped.
