The electric impact I use is a very old one from a estate sale, don't even know the name of it. Works to remove tires from my trailer as well as mower blades. Seems to work much better than my air impact, maybe the air is not a very strong impact wrench that I use. Seen a neighbor use a dewalt cordless to remove tires from a 3/4 ton truck, could not believe it worked as well as it did.:drink::drink
Like there are compressors and COMPRESSORS , there are air tool and AIR TOOLS there are also electric tools and ELECTRIC tools.
Bert ran his shop on Milwakie? cordless tools with 5 batteries as on some of the commercial high hour machines the blade bolts were very tight and might require a single battery for each spindle.
I run my shop on air because I already had air tools and $ 300 bought a lot more air ratchet than cordless ratchet.
My landlord bought a 540 lb Remmington impact gun & I was so impressed with it I bought a slightly smaller one 460 lb.
Both run at 90 lb air pressure, but to get that at the end of 30 yards of flexiable line you need to put in 120.
My compressor is a twin cylinder 2Hp 10 gallon tank and occasionally have to wait for the compressor to catch up. Mine was $ 2000 new
The landlord has a 2 gallon single cylinder 1/2 Hp compressor & he always runs out of air his was $ 300 new.
Both get the job done his just takes a bit longer
Prior to that we both had what you would call Harbour Freight air tools ( $ 100 for chisel , wrench, impact , inflator & some sockets in a pretty moulded case ) and neither of the compressors could pull off really hard rusted bolts with out a lot of heat & penetrating oil, so I would advocate for spending more on top shelf tools than top shelf compressor particularly as it is for occasional use.
All air tools have a minimum air requirements included in the instructions, so get your gun first then find a compressor to match it.
I also have a petrol powered air compressor with a 2 Hp Briggs sitting on a 2 gallon tank running a tiny 10 ft/min compressor.
Hooked up to the good gun, it pulls the old rusted 1 1/2 " bolts off the farm tractors no troubles, it just requires 3 minutes to refill the tank between uses. The old gun would not touch them.
Cordless tools are a lot easier to use but OTOU you still need a compressor to blow up tyres, mend tyres & blow down the crud off the mower so I would go for air.
I have a dozen or so air "dusters" some with tiny ( high pressure ) outlets others with big ( low pressure high volume ) outlets, a couple of really long ones 2' , 3' and 4.5' which ar really handy for cleaning out under decks & around frames without getting yurself covered with crud.
