Operator Safety This machine is capable to amputating hands and feet and throwing objects. Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. The triangle in text signifies important cautions or warnings which must be followed. GENERAL WARNING WARNING ALWAYS shut off the tractor.
Operator Safety TRAINING 1. Read, understand, and follow all instructions on the machine and in the manuals before operating this unit. Be thoroughly familiar with the controls and the proper use of the equipment. Know how to stop the unit and disengage the controls quickly. 2. Never allow children to operate the equipment. Never allow adults to operate the equipment without proper instruction. 3. Keep the area of operation clear of all persons, particularly small children and pets. 4.
Operator Safety CHILDREN Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the unit and the operating activity. Never assume that children will remain where you last saw them. 1. Keep children out of the area and under the watchful care of another responsible adult. 2. Be alert and turn unit off if children enter the area. 3. Never allow children to operate the unit. 4.
Assembly WARNING Before beginning any service work turn off the PTO, set the parking brake, turn off the ignition, and disconnect the spark plug wire(s). Note: Recommended Accessories Rear wheel weights and front counterweights are recommended. For operation on slopes greater than 15% (8.5°), front counterweights are required. Never operate on slopes greater than 17.6% (10°). Modify Manual Lift Linkage (Manual Lift Models Only) 1. Place the lift lever in the attachment-raised (back) position.
Assembly 5. Install the pivot capscrew (AE, Figure 4) securing the new lift link (AI) to the lift lock (AF) and lift lever (AG). 6. Place the lift lever in the attachment-lowered (forward) position. 7. Check the front lock plate capscrew (AH). If the capscrew is grade 5, replace with the grade 8 capscrew (A) provided. See Figure 4 to identify correct capscrew. 8. Place the lift lever in the attachment-raised (back) position. 9.
Assembly Hitch Installation (All Models) 1. Install the hitch support (AL, Figure 6) on the inside of the drawbar support (on tractor) using four capscrews (B) and four nuts (G) as shown. G 3. Secure the hitch assembly bracket (AM, Figure 8) to the outside of the drawbar support and hitch support using two capscrews (D) and two nuts (I). FULLY TIGHTEN HARDWARE IN STEP 2. I B D AM Figure 8 4. Install the hitch assembly (AN, Figure 9) on both sides of the drawbar support.
Assembly Pulley Assembly Installation (All Models) 3. Mount the front idler pulley assembly (AQ) onto the left side of the lift shaft (AR) as shown. 1. Install the rear idler pulley (AO, Figure 10) in the front hole on the left side of the hitch assembly. Secure using capscrew (E), two washers (O), step spacer (P), and nut (J) as shown. NOTE: The front idler pulley assembly (AQ, Figure 12) should be pre-assembled with loose hardware. The hardware will be tightened after belt installation.
Assembly Lift Rod Installation (All Models) 1. Verify that the threaded rod assembly (AU) was assmbled as shown in Figure 14 . 4. Entering from the right side of the tractor, insert lift rod assembly (AW) above rear axle and between the right rear tire and frame as shown in Figure 16. Slide the lift rod assembly (AW) onto the right side of the lift shaft (AX) through the lift lever assembly (AY) as shown. 5.
