PTO Gen, chainsaw, or ...

[billbill1]

I have an 041 AV Stihl that I got used in 1980, I have cut lots of cords of wood with it. The fuel line rotted of once and I had to buy a new muffler ($65) a year or two ago. It is one tough old saw. I had an 024 AV given to me about 15 years ago, it is so much lighter and me getting older, the 041 AV has been retired to getting the 024 unstuck in emergencies. Both have been excellent saws, the Husky's are good too, I've just never had the need to own one (yet). I heat entirely with wood so my saws get a good workout yearly. I've never been around Poulan saws so I can't comment about them but you can buy them reconditioned from Northern Tool pretty cheap. Folks I know have bought them and are satisfied.

The only things I don't like about the Husky are: 1)it seems to use about 2 tanks of bar oil per tank of gas, my old Stihl was the other way around, you knew that at the end of the second tank it was time to fill up the bar oil, this way you never ran out and risked burning up your bar. 2)the bar oil leaks out while in storage, you have to place it somewhere you don't care gets covered with bar oil or put cardboard or something under it.

Charles,
Husky states in their manuals that they design their saws for the gas to run out before the oil does. From what you say it sounds like you're using the wrong chain oil. The leaking may be an oil that is thin and this may be why it is running out too.

Just my opinion.

I have an electric chainsaw and 2 gas chainsaw. The electric is great for being up in a tree for pruning, that is where it stops for greatest. The gas ones are a homelite and a stihl with 16" bars. Both were used and bought for $85. They have been great.

I have an 750 watt inverter hardwired in my Xterra. I do some offroading and it powers my laptop for live mapping. Anywho, inverters are great for powering small things, but I wouldn't run my e-chainsaw off of it.

I'd skip the inverter solution if you don't have a minimum of a couple 100 AH batteries in parallel and a HD alternator.

I have an old Husqvarna with a 32 inch bar and an engine the size of a small dirt bike but it has good compression, starts OK, and doesn't take long to cut a fair sized tree. I have a couple 16" Macs that start easy and cut well and don't make my arms want to fall off at the shoulders before lunch like the Husky. The little saws are way better for cutting off the limbs of the tree the Husky drops.

I too think running a tractor to power a little electric chainsaw is lousy economics. I paid $500 FOR A 6000 Watt continuous, 6500 surge, generator about 7 years ago and use it a lot. It still works fine, starts good, and powers my electric chinsaw on a telescopic pole, my MIG, and most of my power tools except the air compressor and plasma cutter at the same time.

I'm not a fan of babysetting a bunch of gas engines to try and keep running year to year.. however.. if i lived in a forest.. i think I'd have a gas chainsaw. i only have a few trees onmy 13 ac.. so i also use electric... I opted for a pto generator... I know my tractor will start.

It's not as easilly used as a portable generator.. but it works.. and florida see's lots of hurricane down time.. so ....

I think you should look a the 7kw head from northern.

good luck

I have about 20 acres with about 10 oaks with oak wilt I need to cutdown. I have an adequate electric chainsaw for the job which I love (it ALWAYS starts). But no electricity where its needed, so a generator is a possibility. I'd like some help deciding from the following choices as its a close call I think:

1. Good gas chain saw maybe Stihl $350
Could use over long period for firewood, clearing, but not sure it would get enough use
for the cost relative to other more versatile choices and given I already have a decent
electric chainsaw I can use where there's power

2. Standalone 4KW generator, maybe $400-$500
Could use for other things I might need remote power for in projects
like drill, lights, pump, and emergency power.
But, like option 1, its another engine to deal with and keep running. And I've heard these
generators only have a 1000 hr. lifetime IF you can keep it running.

3. PTO Generator, maybe $900 (Northern Tools 4KW) - $1100
Could use for even more things than option 2. such as light MIG remote, etc.
Already have 24HP Kubota, so may be more reliable and cost effective solution over
the long haul than option 2., no extra engine to maintaine, etc. But do I want to
put engine hours on a $10,000 tractor for remote 110vac ? Nice for emergency power
like option 2., but unless we get invaded and are under siege, power outtage doesn't
seem a big reason for generators here. We have maybe one outtage a year lasting
8 hours at most, candles work fine, no hurricanes. But I definitely could see use of
remote 110VAC on 20 acres doing stuff other than just cutting down 10 trees.

Any suggestions ? Remember I can only have ONE. Ah me, tradeoffs, tradeoffs...

Thanks,

Bob

Dont underestimate the convenience factor of having significant AC power at the flip of a switch on your tractor.

Here is text of my posting in a previous thread regarding experience with inverters on tractors.

I have direct experience with running Remingtons 14" Limb and Trim on both Xantrex and Vector 1000W inverters. This has turned out to be a long term compatible combination. The saw is rated at 8.0A, 120VAC, which means it requires around 960W at load. The Xantrex has been mounted on our BX1500 hood for years and the Vector is on the Kub 2550 also long term. The invertors pull about 100A to run the saw so DC wiring must be good. This is more than the tractors alternators put out but with the engine running even on the little one - - a 10A alternator - - you can do several continuous minutes of heavy cutting or 20-30min limbing before the inverter cuts out due to low supply voltage. I have had trouble with other inverters in these useage conditions. These are mechanically and electrically robust. Ive had no problem with the startup surge except when I had a poor DC connection. You can spot check those by running a 500W shoplite or other substantial load and measuring across each DC connection with a digital Voltmeter. This will allow you to compare the quality of each individual connection. You want very low voltage readings like 0.1V or less at this 60A load. If not, the higher loads inherent in startup will cause the inverter to kick out because it isnt getting high enuf supply voltage.
I love these things - lets my wife use a chainsaw. She cant pull enuf to start a gas.
The 1kW Xantrex cost me $70 at Costco. Its been on the hood of the BX 3yrs sometimes in the rain. No problems. Cheap. When they sold the line out the price dropped to $30 and I bought 2 more. Xantex makes a 1.5KW that I want to put on the big Mahindra. Regarding running the tractor at high RPM to get good charging system output - In my experience a 1500rpm idle is sufficient to get very near max alternator output. Battery/charging system/tractor have never been an issue. You dont even have to run the tractor for incidental cuts or use of drills or recip saws. A circular saw needs all you can get out of the 1kW tho. The 1.5KW would be right.

"You haven't lived until you've had to use your backup saw to cut your regular saw out of a pinched tree and then used your ball hitch to hammer the saw bar straight enough to run a chain.

Been there, done that. Used a rock instead of the ball hitch, but found the process equally annoying I'm sure. It was educational - won't make that particular mistake again.

I'm another vote for buy a good gas chain saw. Used Husqy and Stihl, think they are both good saws. Prefer the Husqy for its lower price and vibration. Never used the Poulan Pro though.

And keep the chain sharp - makes a huge difference. Read the thread on HF chain sharpeners - I'd recommend them, beats the **** out of filing.

 

[daTeacha]

I sharpen mine with the Dremel and correct stone.

Not wanting to find my old saw left out of the bragging about tough saws, my McCulloch 10-10A still runs fine but very loud as always. Has been run over by the tractor ( both wheels ), pinched, squashed by trees, and suffered other assorted insults over the years. This is an old McCulloch, not one of the new ones. My Stihl is plastic, but seems equally tough. I haven't run over it yet, though. Hope I don't

Spyder,

When your inverter kicks off due to low battery this is telling you that the battery is well below 50% discharge. (I think xantex shuts down at 10.5 volts, dangerously low). Batteries are rated cycles, that is, the life of the battery is a product of how many times it has been discharged/charged. Deep cycle batteries like the ones used in solar systems and golf carts are designed to recycle. The deeper the discharge the lower number of cycles the battery will last even for those types of batteries. The battery in your car or tractor is not a deep cycle battery and it is not designed to deep cycle.

Bottom line is to be very careful not to approach the inverter shut off voltage as you are shortening the life of your battery tremendously.

As for inverters. The cheap inverters that you buy in Wally Mart or other outlets are called ‘modified sine’ inverters. This is basically a square wave and square waves do not run certain things very efficiently. I could go into the harmonics of the wave and losses incurred but there is a lot of info on this floating around the net.

The motor in an electric chain saw is a brushed motor which runs ok on a mod sine inverter but it does increase the heat the motor runs at somewhat. (AC motors like in your washing machine and fridge run hotter then the brushed AC/DC motors. They also run at about 20% less efficiency)

Bottom line. Be careful what you run on a mod sine inverter. Don’t run things like battery chargers or welders. On welders the transformers are not equipped to run a mod sine. What happens is the transformer core saturates and this leads to overheating.

I've used an electric for light duty stuff. Don't think I'd want to use one for doing a whole tree, keeping track of the cord, etc. (ain't talking about wood cord either).

DON'T buy a cheap generator. Been there done that. The better ones will set you back more than $400-500, closer to $1,000-2,000 for a good one.

I've a 35 year old 009L Stihl that was finally giving me some starting problems. May need to finally change out the air cleaner. Think I changed the spark plug once. ALWAYS emptied the fuel out and ran it dry. Didn't do that just ONCE and regretted it the next attempt to start it. It is so old though, it doesn't have a primer or anything like that, just carb and choke and hold-throttle-open device. Just acquired another chain saw last Saturday at an estate sale for $60 that probably has been used once. It was full of fuel and fired right up. I drained it and ran it dry.

If you buy a gas chain saw, buy a good small one. They're a whole lot easier to use than a big one for most chores. Rent a big one when you need it. I can barely pull the cord to start those big ones and wouldn't want to be lifting one all day to do small limbs.
