Installation Loose Parts Note: 2 Use the chart below to identify parts used for assembly. DESCRIPTION QTY.
Installation Assemble Blade 1. 3. Lift and rotate channel and trip spring assembly so holes align with lower blade mounts. Slide rod through holes and secure with (2) 1/8 x 1” (26 mm) cotter pins (Fig. 1). Apply general purpose grease to the pivot area of frame and channel. Slide channel between frame mount and secure with 3/4–16 x 3-3/4” (95 mm) bolt, up from the bottom, and 3/4” locknut (Fig. 3). IMPORTANT: Do not tighten nut and bolt excessively to cause binding on channel as it pivots side-to-side.
Installation 4. With index handle vertical attach cable Z end to back hole of triangle index plate (Fig. 4). 5. Attach control rod (end with welded washer) to index handle and secure with large hairpin cotter (Fig. 4). 6. Move index lever to center position and adjust cable turnbuckle so the index pin is pulled out of channel when the release lever is squeezed and blade moves side-to-side when lever is pushed and pulled (Fig. 4). 7.

Operation 2 POTENTIAL HAZARD • Hitting fixed objects can cause the tractor to stop abruptly. 3 WHAT CAN HAPPEN • Stopping abruptly can cause loss of control, equipment damage and personal injury. 1 HOW TO AVOID THE HAZARD • Travel at a safe, slow speed. • Check area to be plowed and mark all fixed objects so they can be avoided. 2266 Figure 18 Attachment Power Lift The attachment power lift (optional on some models) (Fig. 18) is used to raise and lower attachments. Raising Attachments 1.
Operation Attachment Lift Lever Adjusting Dial-A-Height The attachment lift lever (Fig. 19) is used to raise and lower various attachments. The Dial-A-Height control (Fig. 19) is used to limit the downward travel of the attachment. The Dial-A-Height knob is rotated to change the location of this stop, up or down. Raising Attachments 1. Depress the clutch and/or brake pedal(s) to stop the machine. 2. Pull attachment lift lever rearward until latch locks.
Operation Adjusting Blade Index Adjusting Blade Trip Springs The blade can be indexed side to side, in 5 positions. The direction is controlled by the handle on the right frame (Fig. 20). The blade trip springs can be mounted in 4 positions. The top hole provides greatest scraping pressure and the lower hole least scraping pressure (Fig. 21). 1. Squeeze the release lever toward the handle (Fig. 20). 1. Remove hairpin cotter and slide rod out from blade and springs (Fig. 21). 2.
Operation Tips for Using Snow Blade Remove snow as soon as possible after it falls. This produces best snow removal results. Snow is generally removed from driveway by making one pass down the center and then plowing snow to either side on successive passes. If tractor looses traction when using snow blade, wheel weights and tire chains are available from your dealer. Blade trip springs can be adjusted for scraping aggressiveness and surface conditions. Second hole from the top is recommended for snow.

Maintenance Reversing the Scraper Blade Storage The scraper blade contacts the ground preventing damage to the snow blade. Periodically inspect the scraper blade for wear. When scraper becomes worn, before working surface contacts the housing, reverse the scraper blade. 1. Before long term storage wash the blade with mild detergent and water to remove dirt and grime from the entire attachment. 2. Check the condition of the scraper blade; refer to Reversing Scraper Blade, page 16. 3.
