The height of a vehicle can vary greatly causing your BOSS V-plow to sit uneven with the ground. Check your Push Beam height first should you notice your cutting edges are uneven with the ground. 

1. 1. Remove the ½” Nylon Lock Nut from the Eye Bolt that holds the top of the spring to the plow. Start with the outer springs first as these will need to be removed before the inner springs. 
2. 2. Once the Lock Nut is removed, lower the Eye Bolt until it is no longer through the hole on the top of the plow. (Note: The entire coupler tower may need to be lowered in order to remove the springs. Use a jack to support the coupler tower, raise the kickstand on the plow, and safely lower the coupler tower until the springs can be removed).
3. 3. Rotate the spring in order to remove it from the rib in the Push frame Attachment Bar. Once the outer springs are removed, repeat the process for the inner springs. Affected hardware is recommended to be replaced at the time of spring replacement. 

4. 4. For replacement, begin by installing the Eye Bolt onto the end of the spring. Install the Push Nut Retainer onto the Eye Bolt (tabs must be facing away from the Eye Bolt). Hook the springs through the holes in the Push frame Attachment Bar and rotate springs up until Eye Bolts can be reinstalled through the top of the plow.
5. 5. Once the Eye Bolts are inserted through the plow, install the Flat Washer and the Nylon Lock Nut.
6. Tighten each spring. Proper spring tension is achieved when a business card can be inserted between the coils of the spring.

1. 1. To start, support the Coupler Tower with a jack and/or jack stands. For HTX-V, remove the two ½” Nylon Lock Nuts from the Eye Bolts that hold the trip springs in place. 
2. 2. Once Lock Nuts are removed, slide the Eye Bolt out of the hole in the Push frame and rotate the spring out of the hole in the Center Section.

3. 3. For replacement, begin by installing the Eye Bolt onto the end of the spring. Install the Push Nut Retainer onto the Eye Bolt (tabs must be facing away from the Eye Bolt). Hook the springs through the holes in the Center Section.  Align the Eye Bolts through the holes in the Push frame. Secure the Eye Bolts to the Push frame using ½”Flat Washers and ½” Nylon Lock Nuts.
4. 4. Tighten each spring. Proper spring tension is achieved when a business card can be inserted between the coils of the spring. 

1. 1. For V-XT and DXT models, the process is similar. Again, support the Coupler Tower with a jack and/or jack stands. Remove the (4) 5/8” Top Lock Nuts from the trip springs. Slide the Eye Bolts out of the back of the Push frame. (Note: Lowering of the Coupler Tower may be necessary to remove the Eye Bolts.)
2. 2. Rotate the springs to remove them from the Trip Spring Yoke.

3. 3. Reinstall the new springs onto the Trip Spring Yoke. Hook an Eye Bolt to the end of each spring and pass them through the back of the Push frame. Secure the Eye Bolts with Flat Washers and Top Lock Nuts. 
4. 4. Tighten each spring. Proper spring tension is achieved when a business card can be inserted between the coils of the spring. 

The BOSS EXT is built with all of the toughness and innovation you expect from BOSS products. With expandable wings that enhance productivity and efficiency to put winter in its place, BOSS built in a blade-leveling feature to accommodate the variations of push beam heights. Because the wings on the EXT sit forward at a 20-degree angle, you need the ability to adjust the angle of the moldboard to ensure the cutting edge is scraping across the width of the blade, including the length of the wings. This will also reduce any chattering caused by the blade not sitting level. 

Set Push Beam Height

Push beam height is crucial to keeping the push frame level while plowing. Equipping a vehicle with an in-bed spreader will also greatly vary push beam height. The 15-1/2” push beam height should be set up with the vehicle in normal plowing conditions, i.e. full v-box hopper spreader, ballast, tailgate spreader, etc.

Cam Stop Adjustment
The second set in ensuring your blade is level is to adjust the cam stops. BOSS built in a feature to perfect the blade level with our adjustable Cam Stops. There are four Cam Stops located on the backside of the main blade. By turning the cams, you can adjust the angle of attack to level the cutting edge, ensuring it makes contact with the ground for optimal scraping performance. 

Factory Setting


Cam Adjustment Forward



Cam Adjustment Backwards


Directions for Adjusting the Angle of Attack
1. Park the vehicle on a level surface and lower the plow completely. If the plow is not flush against the ground, adjust the angle of attack.
2. Loosen the trip springs.
3. On the cams, remove the bolt in the square hole and loosen the bolt in the center (See Figure 29).
4. Rotate the cam clockwise to angle the bottom of the blade back. Rotate the cam counterclockwise to angle the bottom of the blade forward.
*Use a 1/2 inch ratchet to help rotate the cams.
5. Insert the previously removed bolt, and torque it to 76 N-m (56 ft-lb). 
6. Tighten the center bolt, and torque it to 76 N-m (56 ft-lb). 
7. Tighten the trip springs until there is a gap of 0.8 mm (1/32 inch) between the trip spring coils. 

Watch the video below as a quick reference about the BOSS blade-leveling feature. 

Adjust Wing Urethane Edges 
Once the push beam is set and the cams have been adjusted, the last step is to adjust the wing urethane edges. 

1. 1. Loosen three bolts on the front of the cutting edge and three bolts on the side.

   2. Adjust the cutting edge to approximately 1/8” off of the ground.

   3. Tighten all six bolts, securing the cutting edge.

Prepping Your Box Plow for the Winter Season

Ford, Dodge, Chevy, GMC, Toyota.....F150, 1500, Tundra, 2500…regular, crew or super cab…the variety of truck configurations is vast!  Because every make, model and year can result in differences from truck to truck, unique truck undercarriages need to be designed to give you the option to mount a snow plow on your truck. Due to the configuration differences between each truck, the bumper height can vary greatly, and this could cause the cutting edge on your BOSS RT3 V-plow to be misaligned with the ground upon initial install.

Now that winter is safely behind us, many snow plow professionals have either already stored or are preparing their plow for storage. After such a brutal winter, sometimes preparing your snow plow for storage alone isn’t enough. If you took the plow off this spring and noticed that your plow has more than the usual wear and tear damage, you may want to consider refinishing it. Take a look below for some tips concerning snow plow refinishing.

When your snowplow comes off the truck at the end of the season, it’s not always ideal to have it stationary. Sometimes where it’s first placed isn’t where it ends up staying and it can be a lot of work to move it elsewhere. To combat this problem, BOSS is pleased to announce the release of our newest accessory: a Plow Caster “Dolly” Wheel Kit. This kit is ideal for Homeowners, Contractors and Dealers alike for moving plows around the garage, service bay, or showroom floor. Two separate kits are available for straight and V-blades*. Check out how to install them below:
