    What causes areas of uncut grass with my Toro LT3340 Lawn Mower?
    • D
      donwaltersAug 27, 2025
      Areas of uncut grass at the overlap between cutting cylinders on your Toro Lawn Mower might be caused by turning too tightly, the mower sliding sideways when traveling across a slope, no ground contact on one end of the cutter due to poorly routed hoses or wrongly positioned hydraulic adaptors, pivot pins seizing, or grass build-up under the cutterhead. Reduce the turning radius, mow up/down the slope, correct hose routing/reposition hydraulic adaptors, release and grease pivot points, or remove the grass to solve this.

    What causes a step in cut grass height with my Toro Lawn Mower?
    • G
      Gabriel PattersonAug 28, 2025
      A step in cut grass height at the overlap between cutting cylinders on your Toro Lawn Mower can occur due to an inconsistent height of cut setting on one cylinder, the raise/lower position control not being in the float position, no ground contact on one end of the cutter because of poorly routed hoses or wrongly positioned hydraulic adaptors, pivot pins seizing, or grass build up under the cutterhead. Check and readjust the height of cut setting, operate the position control to the float position, correct hose routing/reposition hydraulic adaptors, release and grease pivot points, or remove the grass.

    What to do if my Toro Lawn Mower engine will not start with the ignition key?
    • S
      Steven OdomAug 25, 2025
      If your Toro Lawn Mower engine won't start with the ignition key, it could be due to the transmission neutral interlock switch or parking brake interlock switch not being engaged, the cutterhead drive interlock switch not energized, or a faulty electrical connection. Ensure your foot is removed from the forward/reverse pedals, verify the setting of the transmission neutral interlock switch, and operate the parking brake switch to the ON position. Also, check the setting of the parking brake interlock switch. If these steps don't work, trace and correct any electrical faults.

    What to do if Toro Lawn Mower has lines of uncut or badly cut grass in the direction of travel?
    • L
      Linda GilbertSep 1, 2025
      If your Toro Lawn Mower leaves lines of uncut or badly cut grass, consider these potential causes: * Tram lining of the cutting edges due to heavy contact caused by poor reel-to-bedknife adjustment. Back lap or grind the edges. * The bedknife is in contact with the ground. Raise the height of cut. * The bedknife has a nose-down angle. Adjust the cutting unit to position the bedknife parallel to the ground. * The cutting units are bouncing. Reduce the forward speed and reduce the weight transfer. * Worn reel bearings/bearing housing pivots. Replace any worn parts. * Loose components in the cutting unit. Check and tighten components as necessary.

    Why Toro Lawn Mower has areas of uncut grass at the overlap between cutting units?
    • H
      Harold HarrisSep 1, 2025
      If your Toro Lawn Mower leaves areas of uncut grass at the overlap between cutting units, it could be due to: * Turning too tightly. Increase the turning radius. * The machine sliding sideways when driving across a slope. Mow up or down the slope. * No ground contact on one end of the cutting unit due to poorly routed hoses or wrongly positioned hydraulic adapters. Correct the hose routing or the position of the hydraulic adapters. * No ground contact on one end of the cutting unit because a pivot pin is seizing. Release and grease the pivot points. * Grass buildup under the cutting unit preventing ground contact. Clear the grass buildup.

    • S
      stacey69Sep 2, 2025
      If your Toro Lawn Mower leaves some uncut or poorly cut strands of grass, check if: * A reel is partially out of contact with the bedknife. Adjust the reel-to-bedknife contact. * A reel is in heavy contact with the bedknife. Adjust the reel-to-bedknife contact. * The height of cut is too high. Lower the height of cut. * The cutting edges of the reels/bedknives are rounded. Back lap or grind the edges.
