Having convinced myself that I damaged the gear box on my rotary mower (machines commonly called by one brand's name, "Bush Hog") I opened the owner's manual. Yes, I read them, partly to see the illustrations for what can go wrong on the farm.
I've a Frontier 2060 that cost us over $2000 new, and it's the sort of implement that one would expect to give many years of service. I've used these types of mowers for many years, without incident and without doing more than adding gear oil to the gear box or lubing a few grease fittings.
Slip clutches, conversely, require maintaining, something not explained in my manual but only found online. The farmers at online forums seem to love the things, which can save a tractor or gear-box damage, if the clutch is adjusted and allowed to "slip" a few times a year. Otherwise, it seizes up.
Mine has, and I'm looking at a serious repair. But the antiques again beckon: I've an older rotary mower, with the bolt and not clutch in place. It is as safe to the operator as the new technology, so it will go back into service while the new-fangled one is in the shop.
The new one sure is pretty, but pretty is as pretty does. I may get so angry that I'll sell the new mower! While old tractors can be dangerous, many old implements are not. Yet dealers do want to sell us new stuff, don't they?
I've got fields to mow, so our little family of groundhogs (Phil ended up being Phyllis, with three offspring) don't grow too brazen about coming near the new garden. Open ground being a farmer's first line of defense, there's cutting to be done.
