D40 PTO Valve

[Raymond32]

hello,

I purchased a d40 about a month ago, but the problem is that the pto is totally independent of the transmisson, so the clutch pedal does not stop the pto from disengaging. Well, thats my problem, the reason is because Im a fence builder and I have the post hole digger on the d40. when digging, I sometimes I need to stop the pto from turning in seconds. So is there a way I can modify it some way to stop the pto with out using the lever and only use the lever when done digging. Can anyone help me? Is there a pto modulator, I can buy to fixs this problem? Can I put a secondary valve, before the flow gets to the pto valve? Would this damage the PTO?

Thank you /forums/images/graemlins/confused.gif

Most IPTO, except hydro drives, is dependent of transmission , but not dependent of foot clutch. The lever, via hydraulics actuates the PTO clutch in transmission. Just pull lever to off and clutch should be released, stopping power to PTO. Unless D40 is eqipped with PTO brake to stop implement from spinning, that's all I know for you to do. Pulling lever is same as using foot clutch on 2 stage, so I can't see where problem is unless there is a malfunction., In my opinion, IPTO is a nicer setup than live PTO (until you have to fix it).

IPTO is nicer! lever is located on left side of the operator and the hydraulic power lift (H.P.L) is on the right. This why I need to modify some way to stop the PTO with the clutch or install a electrical switch on the right. but thanks you anyway.

I don't understand the issue completely. Do you want both controls on the right (3PH and PTO)? When you disengage the PTO with the lever on the left, the PTO stops instantly because it has a brake. With a rotary cutter it may take a couple of seconds to stop, but with a PHD, it is almost instantaneous. Sitting in the seat with your right hand on the 3PH control and the left on the PTO control seems easy. Is it a problem because you are turned slightly, looking back that the PTO control is hard to reach?

I don't think there is any way short of redesign that you could put the PTO lever on the right side. It's mechanical, not electrical. Engaging the lever diverts fluid up to the PTO clutch/brake. The only electrical circuit is the operator safety circuit and the light on the dash showing the PTO is engaged.

I can see where the pto control placement could be a bit of a pain. My pos, draft, rate and pto controls are all on right side. Not knowing much about D40, I couldn't say if there's an external line from pto valve that you could put a diverter to tank on. I'm pretty sure you don't want to get oil from elsewhere and put full system pressure on pto clutch as most have seperate relief. If it were electric, it'd be simple, except for foot clutch mounting.
I guess old habits are hard to break /forums/images/graemlins/grin.gif .

The PTO has up to .8 gpm flow diverted off the main system flow to operate the PTO, but it's all internal after the control valve. If Ray is very mechanically talented, he might be able to put a lever on the right side console in one of the three remote valve control slots and connect it over/under his running gear to the control lever on the left side so that either side could control the valve. In my estimation, that would be a "trick" to say the least. A foot control would still be on the left side where his clutch is (I think). That would be easier to rig mechanically, but except for being used to using his foot on a prior tractor, I can't see that being any real advantage over the left-hand control.

Amazing things have been done to rig equipment for handicapped people, so this is surely do-able if you want it badly enough. I suppose you could even rig an ON/OFF solenoid so it pulled the control lever. Washing machines have used that kind of mechanism to engage their transmissions for years and years. /forums/images/graemlins/cool.gif
