As Roy said you have live pto not independent.

I think you got that backwards, Bro...

Doesn't the Grand L have the Hydraulic clutch pack,? so that is why you dont need to use the main clutch? and the L series does not. Maybe someone could clarify here.

The Grand Ls are a more refined tractor with more features, such as heavier loader and front axle, hydraulic PTO clutch, external dual three point lift cylinders, isolated operators deck, hydrostatic intead of power assit steering, shuttle shift, Intellipanel, GST electro-hydraulic shifting transmission and other features.
The standard or sometimes refered to as the economy Ls are more like a new updated 8n or MF35 and do not have as many comforts and stick to the older proven tractor designs.

With the hydraulic clutch pack on the PTO there is no need for a dual main clutch as the hydraulic can be turned on and off at any time independent of the main. Also with the GST their is a seperate wet clutch that the ECU controls so there are times you never have to step on the clutch as ot is activated when the shuttle shifter is used or the gear selector is changed.

I think for the money the Grand Ls offer alot of features and are alot more robust and have more advanced engineering in them, you just cannot compare the HP and size but the extras in the design.

He, most likely, has an independent PTO rather then live.

My old 790 had "live" PTO and a 2 stage clutch (worked as described in an earlier post). My current Deere 4400 has an independent PTO drive (doesn't slow or stop when the clutch is depressed). The 4400 is a manual transmission (reverser, actually) so has to be clutched to shift gears.

Ok I just do not see a need for a dual clutch on a hydo with independent pto.

Actually, I screwed up. I missed his tractor was HST.
I do see the need to clutch to engage and disengage the PTO (less shock load on the PTO). My 4400 doesn't use the clutch to engage/disengage but I wish it did.

I'm glad that my B7800 uses a clutch to engage the PTO. Not only can I engage gracefully, but it also gives me an "emergency brake" to quickly disengage if I hit something while mowing, digging, etc.

Ok Roy , I believe his tractor has a live pto not independent pto, because they are telling him to use clutch. I had a b2620 and that was how it worked. Most independent ptos have a hydraulic clutch pack, so you do not need main clutch.
