Bush hogging with D15 - clutch issues???

Hi all.
I've been doing some bush hogging with my gas '61 D15 Series 1. Starting from a dead stop seems to really put a lot of load on the clutch. Far more than plowing. I'm running mostly in 2 low and 3/4 throttle. To save on my clutch, should I put the power director in neutral, engage the pto, and then shift the pd into low?

What do you folks do? I really don't want to kill my clutch.

Thanks!
 
That just doesn't sound right to me. If the mechanically engaged PTO was spinning, movement of the power director to neutral, low or high would have no effect on the PTO. It would keep on spinning. Now, in your case, you want to engage the PTO. I don't believe you can do it with the power director in nuetral assuming the engine is running. I've never even been close to a D15 but am familiar with the D17.
 
Are you using the foot clutch to start all at once? That is what it sounds to me like you are doing. Yes leave Power director in neutral until bush hos is spinning. Start PTO using foot clutch with PD in neutral. Start PTO about I/4 engine speed. Increase engine speed to proper speed then start forward movement with PD. Use PD to start and stop ground speed. Not the foot clutch.
 
Thanks for the advise. That's what I did today - pd in neutral, trans in gear, pto engaged THEN release clutch and get cutter going, THEN shift pd into low. Worked great and sounded/felt like far les load and strain on the tractor.

Bush hogged about 15 acres and all went well...about 75 degrees and bright sunshine and the temp never made it up to 160. Ran mostly in 3 low with some 3 high in the light stuff. Using a New Idea 5' pull type cutter. Very happy with the results.
 
Also always stop movement of the tractor using the power director to neutral...shift gears with the foot clutch, throttle down, and put the pd in neutral first and wait a second or two for things to slow down a bit before quickly shifting gears.
 
Indeed...the old D15 won't shift into gear if anything is still spinning... grind, grind, grind. Makes my made at myself when I'm kind of rushing and grind it. It's kind of subtle reminder to slow myself down.
