I finally had time to go over this tiller and make sure it was good to go.Very little lube in the gear box and chain was as dry as a fart. The chain cover was broke off and gone. I found this at an auction about 3 or 4 weeks ago where I bought the tractor blade and a 540 rpm PTO system.I let this go cause I was on a budget.lol As I was paying for my goodies this guy approached me and asked if the tiller would work on his 26hp New Holland, I said that it wouldn't. Then he was like"would you like to buy a tiller" Needless to say,it works great. It does as great of job as my 4850 does.

That is a good hefty tiller. It sure is amazing what those big tines can chomp up. It looks a bit like a the Brinly built tiller that I have.

I wasn't aware that Brinly made tillers, do you mind posting a picture or 2? I wouldn't mind seeing it.

I have rear mount Ariens tiller that Brinly made. It is buried in a corner right now. I need to get it out this week and I will try to get some pictures.

I found several pics online that showed the simularities in the final chain drive and the sheilds. But something wouldn't work to post them here.

And one of your pics showed up in my search for a pic that shows the simularities.

Im curious as to what gearbox is on those 4250's because the manuals say that the 4850 takes the # 4465 and the 4250's take the #4477 gearboxes but both of my 4850's have the 4477 gearboxes and the gearboxes im pretty sure are original from the factory as my one tiller only had one owner before I got it and he said it was original

I will have to check mine out in the daylight. Both my tillers came from the original owners.

What's the difference between a model 4250 and 4850 tiller? Is it just the width.....4250....42" wide.......4850....48" wide?
Other than that are they identical? Can u put extensions on the 4250 to make it 48" wide?
Thanks

The 4250 is center drive with gearbox, chain from gearbox to the enclosed chain to the center of the tine set. The 4850 has the gearbox connected to the enclosed chain drive down to the end of the tine set. The 4850 won't leave the small untilled center strip like the 4250. When soil & conditions are right, the 4250 does pretty much do a complete till all the way across.

I extended my 4250 to about 53" by slipping in outside tiller sections from a Simplicity walk behind tiller that slipped right into the tubes on my 4250's tiller shaft. Holes already in my tubes matched the hole in the added tiller sections. Then I simply cut out, bent & bolted on extensions to the "fenders".

I finally got around to checking the gear boxes out on the tillers and they are both the exact same part #.

Is the 4250 wide enough to cover the wheel tracks?
It's within 1/2" on my 1855 with wide turf tires. I never had to "overlap" passes to ensure everything was being tilled.
