Check this out, I have a lawn that I mowed yesterday, or atleast partially mowed. I have a John Deere 717 that I was using on a lot that was approximately, 1 acre of total mowing area. The front yard is about 1/3 of the whole job. Well I trim the front edges out, then trim out the back edges. and I start to mow the back, well I get about 1/4 the way done and the motor starts to get bogged down, well i figured it was just the thick grass and it would recover in a few seconds. well I look down and see the deck stressed out. it was tweeked from where the belt had so much torque on it, motor is still raising hell trying to keep alive. Then all of a sudden not 2 seconds later I hear SCREEEEECCCCHHHHHHHHHH, Pow ! And the whole machine dies, I was thinking oh hell the motor sezied, Well I disengaged the mower. set brake and it started right back up. so I engaged the deck I heard the clutcth kick in but no action from the deck so i shut it all back down. I find the Deck Drive belt snapped in half. so I reach under to move the blades to turn the spindles Cause I knew one of them had to seize. Sure enough the right side spindle was glowing red and locked up. So I Had decided to finish the front yard with a 21 inch 3.5 horse pushmower. just to at least get that out of the way. what normally took me 20 - 30 minutes. took me over 3 and a half hours...Yeah i was beyond Pi$$ed. Well turns out the warranty had expired 3 days..thats right just 3 days prior, and I called Deere's main office. I told them the situation. they looked me up in their computer bank, and said well we see that you have been a loyal customer. we'll give you half off of the part and free belt to replace the old one. so instead of $90 it only cost me $44 something Tax and all. So that made me a little happier, and has increased my opinion toward the comapny, which my opinion has always been that the were always friendly and easy to work with, they have their moments but for the most part I have been satisfied. But what still gets me is that the old spindle did NOT have a grease fitting on it. but the new one does. Whats the deal with that? should I go ahead and replace the others while I'm at it, or run them till they die also? Thanks in advance.
