Tractor Noob85. Everybody will tell you - get an implement that is - 1) a tad wider than your rear tires & 2) as heavy as your tractor and pocket book can handle. For sure - weight is your friend with land engagement implements.
I have a few land engagement implements. Rhino rear blade - Bush Hog roll over box blade( ROBB ) - Land Pride - land plane grading scraper ( LPGS ) - home made drag. Forty two years out here with a mile long gravel driveway. I've never found any of my land engagement implements lacking because they were narrower than my rear tires. I had one rear blade that was just too light to do summer maintenance on my driveway. The surface of my driveway - a mix of gravel, sand, silt & volcanic ash. Hard as concrete in the summer.
The very best implement for maintenance/repair of my driveway - the land plane grading scraper. Followed by my rear blade. I use the ROBB to create new trails here on the property. I finish these trails with the LPGS. I have 80 acres that is classified as open range land.
BTW - Woods is renouned for making excellent/heavy duty implements. You will pay for this excellence but you will get a product that will last a lifetime and beyond.
How do I determine what category/duty cycle when choosing an implement. I choose the heaviest implement my tractor can handle first - and second, what width will get the job done. And - I buy local.
Within reason - I've never worried about the width of an implement. My rear tires on the
M6040 are set at 80 inches - outside to outside. Rear bade - 96 inches - - Bush Hog ROBB - 72 inches - - LPGS - 84 inches - - home made drag - - 64 inches.
