engine heat blowing on the operator

MARK ROBKE · Jul 23, 2016

I got to thinking about Bill Va's post about hot weather and operating older tractors.I know they are a little newer,but does anyone use a 3088 or 5088 IH or something similar-they blow heat forward out of the front of the radiator,sucking air thru a grill in the top of the hood? Do they keep you a lot cooler with a canopy? Are there any other makes/models that blow air forward? I know dozers do that,but any tractors? Mark

Donno, but someone previous to my ownership installed the fan backwards on my MF180. Didn't cool very well.

A fan installed backwards may make it inefficient but it will not make it blow backwards.

Ford had a "pusher" 6 blade fan as far back as the 9-N. joe

Many years ago I worked as a mechanic in a construction fleet. We had a number of Wain Roy backhoes, one was delivered with a pusher fan. Putting it in service we never noticed this fan arrangement. The machine worked fine until it was driven between job sites at road speed. Then it would overheat, the air was stagnate in the radiator. The incoming air worked against the pusher fan. A puller fan was installed and all was well.

I would think it would make a huge difference. I spent 10 hours or so on the 886 yesterday raking and baling. It was 100. The glass on either side of the pedals was so it you couldn't keep your hand on it.

The biggest design problem with that series of tractor is that the floor is not sufficiently insulated. My feet get HOT on days like that. My big 52 ounce cup of ice water melts quickly on the floor by my feet. I have a carpet square behind the seat that I throw on the floor and slip my shoes off if I am in the tractor for a long duration. If my feet are hot I feel hot.

Haven't seen it done on tractors. I suspect it would quickly pack the inside of the radiator with grass and be very difficult to clean!

That is a common arrangement on fork lifts. They do tend to clog the radiator with oily dirt, which has to be washed out periodically.

RayP(MI) · Jul 23, 2016

Yeah.

MARK ROBKE · Jul 23, 2016

I was told the radiator on these never clogs,and neither does the top grill in the hood.It is interesting to see the fan shaft going thru the radiator,neat design.Just wondered if any other tractors tried it.Mark

Not a tractor, but this one has radiator just ahead of the steering wheel. The fan pushes air forward and out the bottom of the hood.

When my father used to use his JD350 crawler for logging he had 2 fans, the summer fan blew forward and the winter one blew back towards him. It was a job to change them but it was worth it.

john in la · Jul 23, 2016

Am I correct in thinking you are not really talking about a pusher fan that pushes air threw the radiator; but rather a puller fan that is on the front of the radiator so it actually blows forward.

A dozer uses a pusher fan because of the low forward speed and to prevent dust kicked up by the blade from sand blasting the radiator. A tractor usually has the dust behind the machine so this sand blasting effect is not a concern.

Had a 850 case crawler and it had reverseable fan blades for winter and summer

My Kubota B2150 has a pusher fan. It sucks in air in around the cowel and side engine screens.
I have to clean the screens between the fan and radiator very often when mowing.

i have 2 1962 TD6 crawlers. one has a regular fan that blows out through the rad, my parts tractor has a fan with reversible blades so in the winter you could suck air through rad I guess. seems like the operating platform is elevated so heat will flow under you instead of right on your legs and feet.

rrlund · Jul 24, 2016

New Idea Uni Harvester had the fan in the usual place,ran off the fan belt on the engine but pushed air out through the radiator.

Reversible fans make cleaning radiators easier.

The 3788 was the nicest hot weather tractor we had. And nothing we had, had working AC.

Used to be a place here I n Erie PA called Huber reversible fan. They made metal blades with a spring type shaft on the hub end of it. The hub also was specifically made for their blades. On a piece of machinery like a dozer the blade could be spun around to blow heat the other direction depending on what the operator wanted. The blade moved pretty easy with a small bar and an extra hand to spin the blade. I installed some new heat in their shop about 10 years ago and they were not doing real well business. They said at that point most newer construction equipment had cabs with climate control and plastic fans so the product that they made was basically outdated. I think they have since sold out and moved on. Sad but it's progress seemed like nice people and had about 10 on the shop floor.

Deere tried that on the early 3300,4400,6600 and (maybe 7700) combines and it did not work very well in hot weather as the grain dust plugged the intake screens and radiator. They changed to a rotary screen and reversed the air flow but on a hot day made the cab that much hotter. The 3300 I grew up with never had AC and would cook you when cutting wheat. Tom

MARK ROBKE · Jul 24, 2016

Yes,it pulls heat/air thru the radiator from the rear blowing forward.Mark

Our Kubota G4200 diesel, like many other Kubota diesels pull air from the operator platform and dump it on the engine. It actually does work to keep you cooler. There's also reversible fans, which will blow the rad out periodically. I think Merlo tele-handlers use them, and some tractors that build/pack bunks will often have them retro-fitted to them, because of the tendency for the rads to build up with crap.

On another note, in 95 we got a new CIH 4240 with a canopy so us kids would have shade while raking hay. The first time I used it I got kicked off after a couple hours. Then I wouldn't get off the 300 and back on the 4240.

The sun was not near as hot as the heat coming off the engine and transmission, which your calves pretty much rode against the sides of.

After that the SM went on my rake, if I couldn't use it I used the 300.

The air going through the radiator comes from the screen on top of the hood but the fan also pulls air around the sides of the radiator. This air comes from below the the side hoods to help cool the engine compartment.
