    Why is there a step in cut grass height with Toro LT3340 Lawn Mower?
    • A
      Angela RyanSep 8, 2025
      If you notice a step in the cut grass height at the overlap between cutting units on your Toro Lawn Mower, it could be due to: * An inconsistent height-of-cut setting on one cutting unit. Check and adjust the height-of-cut setting. * The raise/lower position control not being in the float position. Set the position control to the float position. * No ground contact on one end of the cutting unit because of poorly routed hoses or wrongly positioned hydraulic adapters. Correct the hose routing and the position of the hydraulic adapters. * No ground contact on one end of the cutting unit because of pivot pins seizing. Release and grease the pivot points. * No ground contact on one end of the cutting unit because of grass buildup under the cutting unit. Remove the grass buildup.

    • G
      gmartinezSep 9, 2025
      If the cutting units on your Toro Lawn Mower aren't following the contours of the ground, check the following: * Incorrect hose routing or orientation of the hydraulic fittings.

Correctly route the hoses and orientate the fittings as necessary. * Pivot points that are too tight. Release and grease the pivot point as necessary. * Operation in the ‘hold’ position. Move the position control switch to ‘down / float’ position. * Weight transfer set too high. Reduce the weight transfer.

    Why Toro LT3340 Lawn Mower leaves lines of uncut grass?
    • S
      Stephanie MontgomeryAug 26, 2025
      If your Toro Lawn Mower is leaving lines of uncut or badly cut grass in the direction of travel, consider the following possible causes and solutions: * 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.
