The driveway gets pretty hard in the hot N.C. summers. The Oliver is plenty heavy to dig with the box scrape. But a box scrape is not really the best tool to build a crown on a gravel drive. No angle adjust and does not throw gravel from the driveway edge back to the middle crown. A scrape blade would work better to build crown (for drainage) but I have not yet purchased a scrape blade. My post is really about ability of light weight subcompact to dig sufficient into hardpack gravel to maintain the gravel drive. Will a 1,700 lb tractor dig well enough to pull the gravel back up?
Related to tearing up yard, we mow about 4 acres mostly yard that was previously pasture. So it is a mix of field grasses, clover, etc. . . my wife loves to spin around the Z-turn so she has already created a lot of bare spot divots in the yard. Not trying to have golf fairway yard. My thinking is that a subcompact would do less rutting and tracking in the yard that the heavy Oliver tractor. The Oliver bare weight is 3,750 from TractorData - - mine has filled tires and my 200 lbs - - I am easily well over 4,000 with the aggressive Ag tires. Hoping a subcompact with R4 would do less rutting and tracking in yard.
Before you buy another tractor, or a blade ......
You should jump in your car. Get on I-40 and head West for exactly 100 miles.
You will be in Newton, NC., the home of Everything Attachments.
They build the PERFECT blade for your needs.
You can see their video on:
Tractor Attachments And Skid Steer Attachments For Any Tractor Or Skid Steer
They call it their "Deluxe Scrape Blade", and for whatever size tractor you choose, they make the exact size blade you will need, with excellent offset and angle features.
I have 3 different rear blades, and also have a KK box blade.
For the money, the EA "Deluxe Scrape Blade" is absolutely the best.
EA prices include "free shipping" within 1000 miles.
If you can pick it up in person, perhaps they could shave as much as $200 off their listed (with free shipping) price. You would, of course, then, need to pay NC state sales tax.
