52 in ex mark blades hitting

[southam]

Just installed 3 new blades..engaged the blades and 2 were hitting each other. they seem the same size i took off.. is the middle blade slightly smaller???

 

[BlazNT]

No the blades should be the same size. They may need to be clocked. Model number of the mower and I can look it up.

Hey thanks,,, Just got back from repair shop. They said no blade set position.Makes sense to me cause if they hit something hard they could move position. Just the right and middle blades touch. No play in bearing .. model LZAS27KC524

 

[BlazNT]

Check the bearing in right and center spindles. They may be going bad. Also check the spindle bolts make sure the are tight.

Southam - If the blade has taken an impact, the deck and/or cutter housing spindle could be bent. To check the spindle, remove the deck belt and spin the blade from the underside of the deck watching the blade bolt. The bolt should run concentric, if it runs in an ellipse, the spindle is likely bent. To verify the deck is straight, remove the cutter-housing and place a straightedge on the topside of the deck; check for daylight under the straightedge.

Please contact Exmark Customer Service at 800-667-5296 with your model number and serial number if you have further questions. The team is staffed with trained technicians from the factory who can help you troubleshoot your issue. Thanks.

Try measuring the blades for length to determine if one is shorter.

Blade clock, timing, positioning when installed. If your mower has standard V belts they can be timed when installed but after the first pto engagement I guarantee they won't be timed even if they hit nothing but air.

Wow the shaft is $115.00 I'm glad I don't have an eXmark. I can replace all of mine (3 complete spindles) for $92.00. 250 hours and only had to replace one. Would not of had to replace that one if I had cleaned out the small wire that wrapped around the spindle. No I just mowed with it for one season. Could not understand why the left blade always cut about 1/16" lower than the others at the end of the season.
