I have a 3 month old td33d, and have corrosion problems all around the battery area. Is there acure for this besides constant cleaning? Also I want to buy a rear blade. Not sure of size or brand. I am loking at 6' landpride or woods.Is 6' wide enough,and what is a good price for these brands? Will use mostly for snow removal. thanks, pat

Clean the terminals and any metal parts that are corroded with a wire brush then wash with baking soda water. Then rub some grease on the terminals and metal parts that were corroded. This is the best and cheapest thing I know to do.

A battery gets a lot of pounding in a tractor with no suspension. I would check that you do not have a crack or leakage. A battery should not corrode that fast unless you have leakage. One of the prime areas for leakage is the seals around the posts. If you have acid around the battery posts then the seals are leaking and the battery needs to be replaced. You can check for the acid with the baking soda. Under warranty in this case.

You right Peters, it shouldn't be corroded at this early stage. Another couple of reasons for this problem come to mind though. Could it be the tractor being used at extreme slopes, causing the battery acid to seep through the plugs? Or the tractor over charging, causing the acid to boil out?

A problem discussed here awhile back was a very good thread. The discussion was about a battery venting problem. Corrosive fumes were sucked through the rad. General corrosion and a shot rad were reported. Various solutions and I think a factory fix was identified. Unfortunately I can't recall if the tractors discussed were NH or JD. ....

I believe the thread in question was a JD.
Mix your baking soda with water and then drop it on the top of the battery if you have acid around the vents then it is boil over, if it is near the posts then there is a problem.
During the battery construction an expoxi sealant is poured around the posts to seal the post area. This is under the polypropylene cap. If the seal is bad then the acid leaks around the posts and corrodes the connections quickly. ....

no corrosion around conections. I can't say about overcharging, (idiot lights instead of gauges). Also I talked to guys I work with, and they have the same problem. corrosion is on the battery baseplate and the bolts on the hood latch. thanks for the advice. tractor is a NH. ....

I'd do the battery cleanup and inspection stuff and see if the battery gets hot after prolonged operation to informally check the over-charging question.

There are formal tests described in manuals for testing the entire charging system. However, the formal tests, at least for my 1710, use a variable carbon pile load that few people would have. The general idea is that normal operation of an alternator/regulator/battery can't be checked except when they're under a load, and a known load makes for more accurate results. Some automotive work avoids the need for loads by turning on all lights, blowers etc. for a load but tractors usually don't have enough accessories to create adequate test loads. Besides, a test load for my 1710 would come close to blowing the main fusable link.

Nobody commented on the blade question. The big-name manufacturers have sites that give specs for their products. Recommended HP range usually is given, which I interpret as PTO HP. The recommendations tend to be a bit conservative but are good guides. I don't have a blade so I can't say what to expect, but I run a 6' box scraper with 24 HP and turf tires. I think scrapers take more HP than blades. Of course it depends on how they're used. I think the TC is around 28 HP and the rear tires track around 5'. A 6' blade would cover the tracks but wouldn't allow much angling and still cover the tracks. The TC might carry a bigger blade OK but maybe somebody has experience.

I had the same experience with the battery after I bought the tractor one year ago. I was on the look-out for the problem because I had read about it here. I made a baking soda solution to stop the acid. I have been waiting for a sealed battery or one like my garden tractor that has a vent tube you can route to the ground. Many of us are waiting for the same battery. The vent caps were not designed very well on these batteries.

I bought a Rhino 6ft. blade when I bought the tractor. The blade was new but the paint was faded and it had a few rust spots started. They sold it to me for $100. I'm happy with it and plan on repainting next year. ....

Qouted about $400 for a WOODS RB72' rear blade. Skid shoes run about $100 more. I plan on buying one soon for snow removal. Have ordered a TC33d and prefer the 6 foot size blade. ....

I just found a battery box at Walmart - am planning to put mine in the box to prevent any issues here. Yep - I know it sounds nuts but I have lost a lot of metal in the past to leaking batteries. Will cut slot for hold down bracket. ....

I was at the local NH dealer checking out tc33's. He had six rentals which ranged from 66 to 160 hrs. All had battery acid damage. Some was so bad that the crome paint on the head lights under the hood was 50% gone. And lots of rust. ....

I would suggest spraying the corrosion prone area with a product like Boeshield T-9 (you can buy it at BoatUS or most boating stores or aviation supplies at airports) which is a corrosion prevention compound (CPC) which somewhat hardens and clings to the metal and is more like a waxy substance when cured. I used stuff like this to combat corrosion on helicopters and also on my Sea Ray and other equipment. Soak the battery cable terminals in a heavy baking soda solution so the solution can migrate up the cables and prevent future corrosion at the connectors.

As for the blade, maybe I am not aware of what you plan to do with it exactly, but I would suggest a landscaping rake instead of a blade. It will be more useful and can do most things a blade can do and more. I personally use a Land Pride 1584 landscaping rake to maintain my 2,000 ft. of gravel driveway and it does a great job. I also use it for pulling vines and brush out of my way. On the other hand, there are some jobs that a landscaping rake just can't do and is not designed to do so. I bought it at the John Deere dealer when I got my 4410 for $650. Good luck. ....

TC29 had the same problem, ate the paint off the steel under/around the battery on my SS model. Is it due to a poor quality OEM battery or some other malfunction, don't know but I do like the battery box idea. If the problem turns out to be leakage due to a defect, I would put the new one you receive with your warranty repair in a box expecting the same thing to happen judging by the number of observations of this problem in N/H tractors. ....

Vibration is a serious enemy of wet cell batteries, esp. with garden equipment and compact tractors with diesel engines, rigid motor mounts, and insufficient mass to absorb the vibration. I use high density foam weather stripping, and stick it to the the bottom of the battery. This, along with the plastic battery box already mentioned should go a long way toward solving your problem. If not, there is always the option of a gel cell battery, at the expense of cold cranking amps. ....

My TC33D is 16 mo. old and is now getting a new radiator and surrounding parts because of leaking battery vents. My dealer went to a dealer convention and found all dealers are wanting a fix for this problem. They want a battery with a vent hose that can be routed down to the underside of the tractor. With no such fix in the works, I found that with a special riser I'll be able to mount a larger sealed battery. I'm going with a Optima 75/35 Red Top. If I raise the battery 2.5 inches it allows the battery to be mounted forward and slightly above the hood latch. Air can flow under the battery (through the riser) so I shouldn't have a problem of overheating. ....

They oughta put the battery in the rear, like older tractors. Poor engineering.

Hello Pat
Considering the cost of a replacement radiator... I would consider installing a dry or gel cell type battery... All tractors I have ever owned develop this problem eventually. Usually sooner than later. The small tractor is just to rough a ride for a lead acid battery... ....

If I was not able to get the Optima battery mounted in the original location, it was going to be mounted behind the seat where the toolbox is now. ....
