  If your Craftsman Tiller won't start, there are several potential causes. First, ensure that the fuel tank is filled with gasoline. If the engine is not choked properly, refer to the “TO START ENGINE” section in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other possible causes include a dirty air cleaner (clean or replace it), water in the fuel (drain and refill with fresh gasoline), a clogged fuel tank (remove and clean it), a loose spark plug wire (ensure it's properly seated), a bad spark plug or improper gap (replace or adjust it), a misadjusted carburetor (adjust as needed), or a closed fuel shut-off valve (open the valve).

  If your Craftsman Tiller is hard to start, begin by ensuring the throttle control is in the “FAST” position. A dirty air cleaner can also cause starting issues, so clean or replace the air cleaner cartridge. Check the spark plug for damage or improper gap, and replace or adjust as needed. Stale or dirty fuel may be the culprit; drain the fuel tank and refill with fresh gasoline. Also, make sure the spark plug wire is securely connected. Finally, the carburetor may need adjustment.

What to do if my Craftsman Tiller engine overheats?

  Jeffrey HallAug 26, 2025
  If your Craftsman Tiller engine overheats, start by checking the oil level and condition; replenish or change the oil as needed. Next, inspect the engine air screen and clean it if it's dirty. A dirty engine can also cause overheating, so clean the cylinder fins, air screen, and muffler area. If the muffler is partially plugged, remove and clean it. Finally, the carburetor adjustment may be improper, so adjust the carburetor to a richer position.

  If your Craftsman Tiller runs, but the tines won’t move, first ensure that the drive control bar is engaged. If it is engaged and the tines still aren't moving, inspect and adjust the V-belt. Also, check to see if the V-belt is off the pulley(s).

  If the Craftsman Tiller shuts off when the drive control bar is engaged, it might be due to the shift lever being set in between the counter rotating till position and the forward rotating till position. Shift to either the counter rotating till position or the forward rotating till position. Another potential cause is jammed tines, so clear the tines.

Why does my Craftsman Tiller engine run but labors when tilling?

  Andrea YoungSep 2, 2025
  If your Craftsman Tiller engine runs but labors when tilling, it could be due to tilling too deep. Adjust the depth stake for shallower tilling. Also, check the throttle control setting to ensure it is properly adjusted. If these steps don't resolve the issue, the carburetor may be out of adjustment and require necessary adjustments.

Why do the tines skip over the ground on my Craftsman Sears 900 Tiller?

  Justin ShortSep 12, 2025
  If the tines on your Craftsman Tiller skip over the ground, ensure that the drag stake is lowered when in forward rotating till mode. Lower the drag stake to resolve this issue.

Why is it hard to shift my Craftsman Tiller into gear?

  Dr. Alexis GutierrezSep 13, 2025
  If you find it hard to shift your Craftsman Tiller into gear, the gears may not be timed correctly. Rock the tiller forward and backward until you are able to shift.
