Live Pto:

I'd like to replace my 1000 Ford tractor, (Shibaura built) with something AC branded but want diesel, and live PTO. I only use my little Ford for spraying nowadays, but it's kind of a pain to stop and shift to neutral so the pto pump will turn to make pressure allowing stationary hand spraying. Using my "White 2-55" is much easier, but the tractor is physically too large to get into some areas needed.

What would be one of the smaller AC tractors fitting the bill of diesel engine and live pto?

Thanks,

 You could do the same with a sprayer... Use a 12 v electric motor to drive your pump, or just change out to an electric motor/ pump built for a spray unit.... I have a small sprayer that has a 12 v motor about the size of a windshield motor with a small pump and puts out 2.5 GPM and works good with 2 wands or 3-4 ground nozzles... Your PTO is running 540 rpm....eliminate that PUMP.... switch that for an electric pump / motor running 3000 rpm and it dont have to be so big... What size is the discharge hose ?

There is no pulsing in the output flow as many diaphragm style pumps offer. Tractor handles the full 60 gallon solution tank well and is not light on the steer axle. Perfect size for the task in my application. 

It would be  really nice to not have to  shift to neutral and let the clutch out to spot spray from the tractor seat.

I certainly agree and have lived with it. However it's like automotive air  conditioning or a cabbed tractor with air conditioning to farm with, it's available and I'm willing to pay for it. 

The Allis 160 has live PTO (two stage clutch), and diesel.

Another Ford could be the 3 cylinder 2000 or 3000. That would be my pick because of

easy parts availability.

Two stage clutches can be touchy as Gatz mentioned.

Don't the later model Allis D10/D12 (gas only) have independent PTO?

Also Oliver 550.

Many Massey Ferguson.

Tractor-Data describes the White 2-55 as having live PTO

Allis Chalmers was the first to build a tractor with "live PTO". Live PTO is the ability to stop tractor movement without stopping the PTO. AC did this for many years with the hand clutch on the CA, WD and WD45 (and maybe more models that I am not thinking of) and the power director on many subsequent models.

Independent PTO is completely different. 

So far I have had better luck with Surflow than any of the other 12V pumps I have used. I really like using a 12V pump for running a hand wand. 

With a calibrated 60psi spraying pressure during application, the hand wand moves 2.1gpm of product adjusted wide open for maximum flow. Evaluating the distance and spray pattern, this is acceptable from the tractor seat. With the larger nozzles installed the product dispensed is 4.4gpm through the spray bar. I did not test at 100psi and switching to the smaller nozzles in the spray bar yields 2.6gpm of product application @ 60psi. I do know from past experience quite a bit more product is applied through the spray bar with the larger nozzles and 100psi pressure as the tractor needs to move faster to avoid soaking. The spray bar has only been used for large open areas, and roadways; hence the larger nozzles. The smaller nozzles will be used for smaller gardens and such and not really to kill anything plant related. I have several friends with "food plots", (large gardens to me) I will be taking care of with this sprayer.

From this testing into a calibrated 10 gallon graduated burette, I'm thinking the 5gpm electric pump would work fine yielding approximately 3gpm @60psi and as Ray mentions, "a lot cheaper than another tractor".

Tractor has always been named "Hercules" and he now has a future with me again.

Thanks,
