    Why isn't my Toro TRX-20 trencher digging fast enough?

      Justin BrooksSep 15, 2025
      If the trencher of your Toro Lawn and Garden Equipment does not dig fast enough, consider the following: * Replace the digging teeth if they are worn. * Evaluate the ground type and change chains if necessary, if the current chain is not appropriate for the ground type. * Shutdown and allow the hydraulic system to cool if it is overheated. If problems persist, there may be an obstruction, contamination, or damage to the hydraulic system, and you should contact your Authorized Service Dealer.

    What to do if the chain does not turn on my Toro TRX-20?
    • R
      ravenmuellerSep 18, 2025
      If the chain on your Toro Lawn and Garden Equipment isn't turning, here's what you can do: * Run the chain backwards and then reduce the chain tension if sand or debris has built up in a tooth root of the drive sprocket. * Adjust the digging chain tension if the digging chain is too tight. If these steps don't resolve the issue, it could be due to a failed trencher boom end bearing, damage to the trencher drive system, or an obstruction, contamination, or damage to the hydraulic system. In any of these cases, contact your Authorized Service Dealer.

    • R
      ryan27Nov 19, 2025
      If the engine of your Toro Lawn and Garden Equipment won't start, starts with difficulty, or fails to remain running, here are a few things to check: * Ensure the fuel tank is filled with gasoline. * Verify that the fuel shutoff valve is open. * Confirm the controls are in the neutral position. * Make sure the choke is on by moving the choke lever fully forward. * Inspect the air cleaner and clean or replace the elements if they are dirty. * Check the spark plug wire to ensure it is securely connected to the spark plug. * Examine the spark plug; replace it with a new, correctly gapped one if it's fouled or the gap is incorrect. If these steps don't resolve the issue, there might be dirt, water, or stale fuel in the fuel system, and you should contact your Authorized Service...
