Hey,

Anyone that snowblows with a snowblower on a tracor - is it necessary to have a live pto or is it just a nice addition? The second thing it, what the bar called that can adjust and is on the top of the 3pt hitch? Do u usually buy these with a tractor or seperate? Thanks.

I am not aware of a tractor with 3 point that has enough horse power for a snow blower that was ever made without a live pto, You are talking at least 80HP for just a 6" layer of snow, more like 120 if much snow and a 8' blower will stall out a 150HP tractor

Bob N.Y. has the answer. Trying to run a snowblower with a transmission driven pto is a type of decission a politcion would make.

If you are looking for a tractor for a 3-PT snowblower, check out the reverse speeds.

Most tractors go too darned fast in reverse for a snoblower, and some go even faster!

To avoid the problems with fast reverse speeds you can use a forward facing snowblower. >Link
I>Link have one and it works well.

I guess the "drive through the snow first" blowers work in some areas, where we are, the darn snow typically gets so deep that driving though it first would not be too practical.

Here is how I deal with the snow... This was a high school vo-ag FFA project back in 1975-1976.

I posted this on another board, they wanted to see a picture of it in action. I need to take one, before winter's over.

The actual blower is a Hinicker, built in Mankato, the rest I built from WC Allis frames, a Deere 55 combine front axle, a Massey 90 combine rear axle, Deere drill boxes for the fenders, and a bunch of new steel.

A Chevy 261 6-cylinder moves it, an IH truck V-8 runs the blower. It has 16 forward gears, and 4 in reverse.

The link you are wondering about is called the Toplink. It is separate from the tractor. Most any farm equipment store, dealer, etc. will have them. Even our nice YT Market place has them.
Live PTO is not required. But IS very nice to have for operations like snowblowing when you get into heavy snow. Nice to have for many other operations around the farm also.

If you dont have LPTO be sure to install an ORC. (over running clutch)

What would the over running clutch do? Would I need one for sure? Thanks.

Without an overrunning clutch or live PTO, a bush hog's blade becomes a huge flywheel directly connected to the back wheels of the tractor. Pressing the clutch does not break the direct linkage, so the wheels will turn until the blade stops. This provides terrifying moments for the operator when, for example, the tractor refuses to stop when you encounter an unseen boulder or it resolutely powers over the edge of an embankment or into a garage door while you frantically slam on the brakes.

Direct PTO/driveshaft links are found on old Ford and Ferguson tractors and the problem is compounded by their low horsepower and high ground speed in lower gears. For this reason most contributors will recommend spending the extra money for a tractor with low gear ratios and live P.T.O. if the purchaser plans to use the tractor with implements.

I"d assume you"d break the tractor in half to add this clutch? So it"d be pretty expensive no? Another name for the clutch is a two stage clutch no? Thanks.

I will tell you the same thing I have told everyone else who has asked this question. Trying to run a snowblower without live PTO is an exercise in futility. An over-running coupler is good for an implement like a bush hog that has a lot of inertia, but would be useless for a snowblower. The resistance of the snow going through the blower would stop it the instant you push the clutch in and then it would be plugged.

We don't have that much snow around here and tha tbig of a driveway, but can we not just pop it into neutral and clean it out then pop it back into gear?

Not very well on the clutch popping, _unless_ you have a tractor with live pto. The snow blower will stop & plug up, or the shear pin will bust, or it will not feed in crusted snow, or..... . It just won't work worth a darn. What tractor is it, how many rear gears do you have, how slow does your tractor go? If you have a _very_ slow reverse possible then it might work out - if you can go slow enough. If you have an N with the fast reverse - just forget about it.

Snowblowing is the absolute worst thing to try to do without live pto. Baling hay is near the top as well, but the flywheel of the baler makes it possible, if you are quick shifting & get realy, real good at double clutching. It's not fun baling, but possible. Snowblowing is much worse without live pto.....

Does not work with a snow blower. Not at all. I like the comment above, it is something a politician would dream up. ;)

The 'top link' on the 3pt hitch typically is sold as standard with a new tractor, but they get lost or kept along the way. You can get one (there are 3-4 different lengths, understand which one you need, depends on your tractor) from most any tractor/farm supply store.

The 'over running coupler' mentioned is for heavy implements that act like a flywheel. Without live pto, whwn you push in the clutch, the implement attached to your pto will spin down slowly, continuing to move your tractor. The ORC will prevent this dangerous thing from happening. It acts like a great big socket wrench, allowing the pto to spin free in one direction. It slips onto your tractor pto shaft, and so most implemts you own will need to have their pto shaft shortened.
