I know two female hay producers. I don't think they see maintenance and repair as gender specific. They repair and maintain what they can and pay for the rest. As a matter of fact, that's what I do
Yep, if you can read a manual, you can do the repairs...
The rest is just having the right tools for the job...
Just don't do like what I saw back when I was in mechanic's school...
We were in Truck Brakes and Chassis class, learning all about air brake systems, truck suspensions, chassis, axles, steering, frames, etc. We were in the lab one day and two other guys and I were a team working on air brake lines, foot valves, park valves, etc. on the front end of the chassis (stripped down truck with the relevant panels installed in the "cab" (which wasn't there) while another team of 3 worked on changing tires on the back end of the same truck chassis... their "team" was sort of the "rejects" of the class, you might say-- these two kids that looked like they were about 14 (and softies like underdeveloped video game nerds) and this "4x4" chick (as my brother-in-law calls them-- 4 foot wide, 4 feet tall LOL:) I had to laugh when I happened to be walking by after getting some tools we needed-- they were in the process of putting an 11.00x22.50 semi tire and rim on the back of the truck, and she says, "if you two will lift the tire, I'll put on the lug nuts..."
"Yeah-- see how far that gets you in a diesel shop..." I thought to myself...
Kinda like when I drove a school bus, and one of the women drivers said something to the effect one day that the MALE drivers should be "required" to load and unload the heavy ice-filled coolers that the teachers have the custodians load in the back of their buses on field trips... I looked at her and said, "You're getting the same pay for the same job as I am, in fact you get paid more because you have more seniority-- so why should *I* (or any other male) have to do PART OF YOUR JOB for you?? Lifting is part of the job, its in the job description... if you CANNOT do the same job I can, WHY are you wanting to be paid the same?? You're getting the SAME PAY, you should do the SAME WORK! I believe in "women's lib"... DON'T YOU??" She got in a huff and walked off...
Oh well... truth hurts sometimes. Had the same BS when I worked at the nuke plant-- get a semi-load of welding gas cylinders in, they call the guys down there to come unload them... they send the women up to count flat washers in drawers somewhere, just total powder-puff stuff... even though they're HIRED TO DO THE SAME JOB and GETTING THE SAME PAY. They SHOULD be down there risking breaking a nail and lugging cylinders off the truck, same as the rest of us...
In the end it doesn't really matter-- I'm slowing down and don't lift as much as I used to; I hurt more than I used to, and I'm more careful, slower, and more deliberate than I used to be when I was young and stupid... in the end it all comes down to "working smarter, not harder"...
Later! OL J R 
PS... I operated the farms for my Grandmother, who owned and ran them til she passed away in 06...
