Land Pride RTR 0550 tiller
I bought this back in Feb to use behind my X748. This is a reverse-rotation, 540 rpm PTO driven tiller, 50 inches wide. It weighs in around 300 pounds, and is set up to mount on either a Cat 0 or Cat 1 hitch. The lower arm connector pins pass through two brackets, and the pins themselves are two diameters for the different category hitches. A removable bushing on the smaller diameter part brings it up to the same diameter as the larger part of the pin, so there are a couple of options for arm spacing. There is no adjustable offset at either the top link or bottom arms.
The tiller came with a drive shaft which has the quick-release collar on the tractor end, and bolts to the sinput shaft on the tiller. Standard is a shear pin, but you can get a slip clutch as an option. The one I got has the slip clutch; I highly recommend it, saves a lot of time replacing shear pins. I removed 4 of the 8 tension springs on my clutch to make sure it would slip before overstressing the PTO on my tractor. I've had no problems, and it is plenty tight and does not slip under use in even compacted dirt, but readily slips when a rock or other debris snatches the tines.
I once owned a slightly heavier, but similar tiller, a LP 10-50. It was forward rotation, same width, but weighed about 100 pounds more. It was one awesome tiller, I used it for almost ten years without a single problem. So far, this slightly lighter tiller is meeting the same service I had with the older one, does just as good a job. The reverse rotation takes a little getting used to, but I had used my forward rotating one as a reverse tiller by backing through the garden.
The reverse rotation tends to dig and leave the deeper stuff on top as you move through the garden, rather than bury stuff from the top like a forward rotation tiller does. It also works against the forward progress of the tractor, so forward movement makes it cut hard ground better, and it doesn't try to push the tractor when you hit something hard. You're actually dragging this tiller forward while it's trying to move the other way.
On the sides are two adjustable shoes that allow you to set tilling depth. If you are in already tilled soil, they don't do much, you can bury the tiller as deep as it will go. There is a rubber skirt along the front of the tiller to keep dirt from getting thrown forward, and an adjustable gate in rear to increase the pulverizing action. On the right side is a removable "leg" that keeps the tiller upright when not hooked up
The only thing the least bit negative I've seen, compared to a forward turning tiller, is that it will pack up if the dirt is too wet. Not really a problem, as if it does that, you shouldn't be tilling anyway.
The cahin drive on the side is self adjusting, and there are grease fittings for the end bearings and drive shaft U-joints. The gearbox has a "oil level check" plug which is also used to fill or empty the gearbox, and all the turning driveline has guards.
I paid a little over $1500 for this tiller, I think a real good value. heavily made, very solid, should last for many years with proper maintenance. The gearbox has a two year warranty.
