wood processor build

Good suggestion Mud. I was thinking similar of trying to find a worn our mini-ex: 5 or 6 cyl and 3 motors along with all the valves etc. But as of next Tues, I've got a 2.0 Jetta available for nothing that I'm thinking of using to power my build next summer.

How will you govern the motor? I have a used toyota 2.2 laying around but don't know how to put a governor on it to control the speed and power. Also checked out those ditch witchs on ebay pretty pricicy even the parts ones. will keep looking for answers.

I have never had much luck looking for parts on Ebay. Seems everybody has a buy it now price and its for more than the parts are worth. Most luck I have found is just checking scrap yards. The machines are sold at scrap metal price and parts are pretty cheap. I bought a pump, mount, and control valve, complete with the joysticks for $20. Bought another pump for $2. bought a complete a620 backhoe attachment for $300. (sold it for $800) You just have to be at the right scrap yard at the right time. With cheap scrap prices right now, selection isnt as great as it used to be, but bargains are still out there.

As for the toyota engine, think about using a cruise control as your governor. The oild dueltz engines we used to use at work had a throttle lock. Motors cranked wide open and stayed there all day.

I was looking up info on adding a governor to an automotive engine last week. This is what I came up with as far as manufacturers. They appear to be a dying breed.
Can't find them for sale anywhere on the net which is odd. I haven't found an engine for my processor so I haven't made any calls.

Many forum threads on this topic say to find belt drive governors off of old construction or farm equipment such as combines.
I have seen inquiries into using cruise control but have not seen where it has been done. (I'm sure it has)

Throttle control on a cable operated automotive engine is easy. Cruise control is an option. I know a couple guys that used a bicycle shifter to rig up a hand throttle on their Jeeps. Anything that will keep the cable taught and the throttle plate at the right position will work.

Now if its a drive-by-wire throttle body, that's a whole different story and out of my league.

A throttle cable will set the throttle easy enough but it does not adjust the throttle when load increases. What is being discussed here is an engine speed governor that monitors engine speed and adjusts the throttle to maintain a certain RPM as load on the engine increases and decreases.

I just did a quick search and this cruise control poped up. https://www.autoelec.com.au/ssl/public_autoelec/store_v4/product_detail.asp?id=2218&cat=52, Its $225 kangaroo money, but there should be American alternatives. At one time JC Whitney sold aftermarket cruise control kits. AudioVox was a major brand back in the day.

They are still available.

Here is a servo motor actuated one.

So I have a question of vacuum actuated vs servo actuated. If my memory serves me right I'm thinking you could easily have 3-4 MPH swings on vehicles in the 80's. Vehicles from the 90's and up you generally set and that's where they stay. So I'd be inclined to think that a servo motor may be more accurate but it is a guess.

The other thing that I would question on any cruise control setup is just how quickly they will react to a change in the engine RPM. Cruise control in cars typically works to minutely adjust the throttle. A car gradually transitions form flat land to a grade. It's not like the car engine goes from no load to 75% load in the blink of an eye which will happen when engaging the splitter in a log that is up against the wedge already.

I'm not saying it won't work, but those would be my concerns.

I would agree, I think cruise would not be fast enough however as Wild Bill stated I know of older massy combines that had governors on their flathead motors however they would be getting pretty old

Really? Since this:

was seemingly directed at me with my comment about using a Jetta motor, I answered with my plans which is just throttle control.

I'm well aware of the difference between basic throttle control and a governor. Sure, a governor is better but look at how many things out there just have basic throttle control that you (typically) set under load? Most small engines are just cranked wide open and left there. My B3300 has no obvious governor as when the RPMs drop from load, they only come back up when the load decreases. The 4050 AC tractor I grew up with was the same as are the vast majority of the tractors I have driven. Why wouldn't the same work for the Jetta motor?
