 Topic: D17 for brushhog
Posted: 09 May 2021 at 11:30am |
|
I have a series1 D17 (gas) that I would like to use for brushhogging (instead of my green thing). I have a couple questions...(1) I assume it should handle a 6foot brushhog ok since I pull a 303 baler with thrower and a wagon ?? (2) Neighbor says I need an overrunning clutch ?? True ?? (I don't use one on the green thing) (3) Anybody have recommendations on a supplier for a 3 point conversion ?? What is the ease of installation ?? Thanks for any/all ideas and thoughts!! Dan

couple of vendors on this site........ both would be glad to explain the installation process if you need... more or less a bolt on item.

the purpose of an overrunning clutch is two fold.. If you hit something and the blade STOPS quickly, you dont tear up the PTO shaft of the tractor.. Also when you want to stop the tractor and push it the clutch, the BUSHHOG will continue to spin for a short period of time and will PUSH the tractor forward.... with the overrunning clutch, the mower spins and slows down while you are setting still.........
its a "GOOD IDEA" for any tractor.. it is not a necessity to make the tractor function.

I don't think an ORC will provide protection if the cutter hits something, at least as I understand an ORC, based on the ones I've used. As long as the PTO is engaged the ORC is going to try to turn the driveline to the cutter any time it is going slower than the tractor PTO speed (it is a one way clutch, it only locks up when the PTO is going faster than the cutter driveline). If you hit something with the blades, and it stops the blades, that is where a slip clutch or shear bolt provides protection to the drive line. You should have an ORC on the tractor's PTO shaft, to prevent the cutter's inertia from pushing the tractor, when you push the clutch. And you should have a shear bolt, or better a slip clutch, on the cutter's gear box input shaft to protect the tractor's pto and cutter drive line/gearbox from shock loads when something is hit stopping the blades suddenly.

Slip clutch, and use the PD to come to a stop, with the blades still turning...

Your right Jim... the shear bolt protects the PTO shaft... my bad !

My "Bush Hog" has a slip clutch. At the beginning of each season, I loosen the plates, run through some heavy weeds until the clutch slips freely and then tighten the nuts back down. I use an overrunning clutch as well...saves a little wear and tear and makes for a little easier gear shifting as well.

We used to pull a 15’ batwing with our D17 IV clipping pastures. It handled it fine. I wouldn’t want to try to mow by the creek where cows haven’t been. That will make the 8010 talk.
As far as an overrunning clutch, if your used to stopping with the hand clutch it’s not necessary. But if your used to stopping with the foot clutch, it might be a good idea. You don’t want to end up through the fence and down in the creek

I definitely recommend an over running clutch!

I agree with DSeries4. If I’m doing a lot of cutting I definitely have an over-running clutch. Only use without when I know the ground and my brush hog also has a shear pin.

Using an AC rotary cutter does not require an ORC. The AC cutter has a built in ORC right behind the slip clutch. Two pins pull the cutter and when you use the foot clutch you will hear a clicking sound and the pins are over riding the motion.

Bush hog with a WD45 over 40 yrs with no ORC without issue. I only use the hand clutch except to engage PTO. Never use foot clutch to change trans gears. It doesn't rip or grind if your motion has stopped. As stated,if you use the foot clutch to do your stopping/starting,shifting gears....you may want an ORC but it's not needed when using the hand clutch (2 spd PD on 17).

I run both D17's on my 12' flail cutter in corn stalks each fall. Cut about 10 - 12 acres with each. Gets them warmed up good before winter. The renter and his son ( few times I've baled them ) roll them up for stock cows.

When I cut in cooler temps in winter (35 to even 60 degrees) with a heavy 6' unit on either the D17IV or one of the D15's, always warm up the oil before getting near trees or fence lines where I want to get real close. Cold fluid will allow the unit to "push", even if you throw the PD into neutral without an ORC. If you go with an ORC, make sure you measure the telescoping distance on the pto shaft halves after mounting the ORC so you have enough distance to prevent binding if running in uneven areas or crossing ditches, on any tractor used.

The 2 speed PD is less forgiving when it comes to free when released compared to the hand clutch on a 45.
