3pt snowblower coversion to bucket attach w/frPTO

[EdMTU]

I am a student at Mich. Tech. Univ. and for my Sr. design project I am trying to modify a rear-mounted International Harvester Model 70 snowblower so that it will run off of the front PTO. Gearing down will be accomplish by a chain drive but I am having trouble visualizing how I am gonna run the PTO shaft down the belly of the tractor. The frame of the blower has already been designed and will be modified to fit on the bucket attachments of the loader arms. If anyone has seen anything like this or better yet has some pictures of something similar to this it would help me out greatly.

Try a search on front snowblower. Front PTO powered ones are typically mounted to the tractor frame not loader. You'd need some kind of safety lockout to be sure you didn't move the loader too high & bust up the driveshaft.

You could run a hydraulic pump on the PTO & put a hydraulic motor on the Snowblower. Might be expensive, but check out princedirect, baileys online or surpluss supply. There are links on this thread hydraulic cylinder

Good luck from a fellow ME.

I should have probably clarified what I have tried to do already. Hydraulics were my first choice for sure but due to expense of the project the decision was to use front PTO. The reason to hook up to the bucket attachment is for a quick attach/detach type of blower. But I do appreciate any suggestions.

Welcome to TBN!

I agree with Hazmat that unless you had some kind of lockout, you could lift the blower and hit the driveshaft on something, or worse, the driveshaft halves could seperate and you'd beat the underside of the tractor to death until it stopped spinning.

Hydraulic drive for the blower would be the only way to give you the option to lift the blower with the FEL arms any appreciable amount.

What would it take? Hmmm.... A mount for the blower in place of the bucket. Need that with either PTO or Hydraulic drive. You'd need proper GPM from the tractor. If the tractor is big enough, you might have enough already. If not, you'd need a PTO hydraulic pump, reservoir, etc... Then you'd need hoses to get to the front of the tractor. And, of course, a hydraulic motor for the blower.

Sooo, figure out how many GPM motor you would need to drive the model 70 blower then see if the tractor hydraulics are within range. If so, I'd go the hydraulic route. If not, I'd go with a front frame mounted design for the PTO blower and skip the FEL mount.

Sounds like a great project. Keep us informed as to what you decide. /forums/images/graemlins/smile.gif

I'd hate to make a mistake and raise the loader to high! /forums/images/graemlins/shocked.gif

EdMTU they are right, a snow blower mounted on the FEL arms and powered by a spinning PTO shaft is an accident looking for a place to happen. Better refigure, powering it with the tractors hydraulics instead.

Provenost builds some hydraulic drive units that go on the loader but 60" is about it using a supplied pump.

We did have all the hydraulics that we wanted to make this work for us but the total cost ended up being to high. We wanted to use Prince HCPK-11C PTO Hydraulic Pump with 40 GPM @ 1000 RPM and 2250 PSI and Char-Lynn 10,000 Series
with Continuous RPM of 429 and Continuous Torque 500 ft-lbs. We wanted the create a beast, but this all this, then hoses, and a tank that we would manufacture it comes out to around 1000 bucks. I will let you know what we come up with, but until then if you have any suggestions they are certainly welcome.

Re: 3pt snowblower coversion to bucket attach w/fr

Would it be possible to use the tractor hydraulics instead? Then you could omit the pump and tank.

What tractor were you planning on using this on and what was the available GPM and PSI on that tractor? Just curious. /forums/images/graemlins/smile.gif
