Service Tips for the Cold Season Ahead

With the winter season fast approaching, now is the perfect time to start thinking about getting your snow and ice fighting equipment in working order. Bonnell is here to make sure you’re not left out in the cold when snow starts falling. Here are some tips from our service department on things you can do to be prepared.


  1. Check the oil. 
    Good maintenance practice says that you should completely change the oil in your plow before storing at the end of the season to ensure the best quality and eliminate any potential water, dirt or debris. Use the manufacturer recommended oil for optimum performance. When getting your plow out for use this winter, make sure to check the oil level and top up if required.
  2. Check the filter.
    One of the most important parts of your plow, the filter, should be checked for holes or backed up debris. Replace a damaged filter before use.
  3. Apply grease.
    Again, it’s wise to grease all plow components before storage at the end of the season to add a layer of protection from corrosion. When getting your plow out for use, you will want to reapply grease to any metal-on-metal applications.
  4. Check hoses.
    Hydraulic hoses can get damaged through impact (e.g. hitting a curb), erosion causing hydraulic fluid to leak, rust, incorrect installation and wrong hydraulic fluid. Any of these problems will stop your plow in its tracks. Prevent downtime by checking hoses and replacing any that are showing wear and tear.
  5. Check all functions.
    Finally, hook up your plow and make sure all the functions are working correctly.


  1. Tighten the belt.
    Properly adjusting the belt tension will reduce slippage and performance problems. Always reference your manufacturers manual before attempting any alterations, and be careful not to over-tighten the chain.
  2. Apply grease to moving components. 
    Make sure all moving parts have been liberally greased to prevent corrosion and ensure optimum performance. Pay special attention to the chain and bearings.
  3. Check all functions. 
    Finally, test the v-box and make sure all functions are working correctly.

  1. Check the oil. 
    Check your oil and level condition. If you notice any water or debris, replace the oil.
  2. Check Power Take-Off (PTO). 
    The PTO takes power from a source such as a running engine and transmits it to an attachment like a plow. Check for signs of wear, and that the hose and wires are secured to the PTO and not rubbing against the transmission or other components.
  3. Replace filters. 
    Replace your return filter, and if applicable your high-pressure filter.
  4. Check all functions.
    Finally, check all required functions are working correctly before hitting the roads to plow.
