Q:

blade engagement HDK19H42 Ryobi Tractor

A:

Thanks for the inquiry and for being a valued member. 

I am sorry to hear of the issue you're having with the tractor. I know how frustrating that is.

This type of issue is typically caused by one of the tractor's safety switches. They can become intermittent when they are failing, and or because of a loose or dirty connection. There are three safety switches on the unit. There is the seat switch, blade engagement interlock switch, and the brake/clutch interlock switch. 

I would start by cleaning the contacts and making sure the connectors are firmly secured. If that doesn't help, you will need to test the switches for continuity with a meter. To help you do so, I have linked a short video below that you can watch.

A:

The tension idler may not be moving back far enough to get the belt as tight as it should be. If you notice where the bracket pivots (on the left side of the mower deck), use a 9/16" wrench to loosen that nut just a little bit. Spray the pivot area down good with some WD-40 (or other penetrating oil) and then engage/disengage the blades several times to make sure the pivot is allowing everything to move.

If that does not change anything then it may be that the engage cable has stretched or that the pieces for the pivot needs to be pulled apart and cleaned up. If that looks to be the case, let me know as it's a little bit involved. Not hard, just involved.

Thank you for using Manage My Life!

ok loosened the 9/16 nut on the pivot oiled with 3 in 1 and white lithium no difference the clutch cable is not stretched it is taught when engagedv the tensioner moves approx 1 -1 1/2 inches when engaged it can squeeze the belt together to touch together when clutch engaged from the tensioner to the engine pulley area. How far should the pivot move the tensioner pulley?

A:

if the idler pulley system is moving far enough that the belt touches together the belt is not correct. just because the belt is the same length some times they are to thin and ride to deep in the pullies making the belt seem to long. that is why it is always a good idea to get a belt from the manufacture because the napa and autozone type replacement belts are usually not the same width but they will match the length. also I have seen many belts that say they are so many inches long on the cover but when measured with a ruler they are not.

Thank you for your question.

I am sorry you are having a problem with the dipstick. I hope that the dipstick broke up far enough so there is a long piece is in the dipstick tube. Use a flashlight to look into the dipstick tube. If you can see the broken part, use a long pair of tweezers to reach into the tube and fish the part out. If you cannot see the broken part, the engine will have to be disassembled to retrieve the broken part. If this is something you would like to attempt please let me know and I will be happy to give you the information out of the manual.
