I have a JD series 100/model 145 48in cut lawn tractor. While mowing yesterday the mower just stopped. engine runs fine, the tractor will start and stop as usual but the blades will not engage when the knob is pulled to engage. When i inspected the belt. it seem loose but not broken. Any suggestions on where to begin troubleshooting?Thanks!Mike
Make: John Deere series 100
Model: model 145
checked belt, it was intact.
Hello and welcome to Just Answer,
The belt should not be loose. Ifit is loose then you need to check the routing to make sure it is not off of one of the pulleys. Your owners manual should have the belt diagram in it. If you do not have the manual, here is a copy of it.
i need more info...please tell me things to trouble shoot...like how do i check to see if the safety features that stop the blades running are intact, etc. Please do not tell me what I've already told you...I'm am looking for answers. If you do not know, please refer to someone who knows john deere lawn tractors.
Thanks so much!
please forward question to someone who is both willing and able to answer.
If the belt is loose then it is not installed correctly. The belt has to be routed correctly and tight. If the belt is routed correctly and it is tight then turn the key to the on position, set on the seat and then pull out the pto switch. You should be able to hear the PTO clutch click. If you hear the clutch click then the problem has to be with the deck belts. If the pto does not click then the clutch itself may be bad. Let me know if you hear the click or not.
I hear the click but the clutch does not engage.
The clutch will not spin until the engine is running. If you hear it click then it will engage when you have the engine running. Make sure the belt that goes from the engine back to the mower deck spins when you engage the clutch with the engine running. If the belt does not move then make sure it is in the groove of the pulleys and routed correctly.
you are frustrating me!!! Of course the engine is running when ihear the click after pulling the knob...it clicks and nothing happens...the belt is routed correctly...remember from my first post....i was MOWING and it QUIT MOWING but the engine kept running...tell me what else to trouble shoot. IF you dont know. find me someone who does. I'm paying for a service but not getting the service i've paid for.
I am going to opt out and let someone else try to help you.
Relist: Answer quality.
AS JR has been trying to tell you, if you hear the click when you pull out the electric clutch engagement switch, then you only have one possibility. The belt is too loose and is not tight enough to engage the blades. This could be because of several different things.1. The belt could have simply slipped off of one of the pulleys and even though it looks correct, ir really is not. Check to make sure that the belt is on all of the pulleys....including the idler pulleys.2. You may have broken a spring that holds the idler pulley to the belt. If this spring is missing, broken, or stretched, then it will not allow the belt to be fight enough to engage.3. The belt itself may have worn on the sides and now is falling too far into the groves of the pulleys. if this is the case, then the belt will seem like it is too long and will not engage the blades.This is just about all the things that can cause this problem.....unless of course there is something wrong with the electric clutch,. And if this is the problem, then the clutch would have to be replaced. Also , just in case, have the battery "Load tested" even if the batteries seem good, they tend to loose their cranking amps with age. if this is the case, then the battery may click the PTO but not keep it engaged enough to turn the blades.Good luck."Please leave a GOOD rating for me as that is the only way I get paid for my time.

Thanks Ranwell! It was the spring. That is what i was looking for in a response, not what JR was providing (although i understand your support for the team). I needed several things to check that is not out there in the mainstream search, not obvious, easily found solutions such as JR was providing. I will rate your service as excellent. Have a great day!
