Rated 1 out of 5 by from Do Not Buy Online ! Bought this Tiller 5 months ago and it arrived with a bad transmission. Because it was bought online none of the "service centers" will touch it. Calls to Troy-Bilt tell me I have to take it 300+ miles to the "authorized service center" in Atlanta, OR pay for it myself and Troy Bilt will review the claim and see if they agree it is a defect. The service line is always very busy and very arrogant about helping you. If you buy this tiller get it from a dealer that will order it for you. You sacrifice the financing, but then it can be fixed locally. The online listed "regional service centers" DO NOT exist and only local sellers are listed, and these are the ones that will not touch a warranty item like the transmission. Have been in shops 4 x and have driven 600 miles totally and still unable to use this tiller.

Rated 5 out of 5 by from Sure Beats a Shovel! This is an easy to use rototiller that doesn't take a weight-lifter to maneuver and use. It really makes gardening easy and quick!

Rated 1 out of 5 by from Not greatly pleased I own an older model Horse that was built in the 80's. I decided to purchase a big red because of the electric start feature. It was purchased locally 3/25/19. Was delivered and found 3 issues rather quickly. Throttle too tight, thus peeling the coating off of the metal cable. Also the handlebar levers would not stop machine. The disengaging rod set to tight, putting too much pressure on this action trying to disengage and place machine in neutral. After sending machine back, these items were corrected. Machine worked as advertised, until hearing a grinding sound a few months later. Sent back for service, and the transmission was found needing to be replaced. After replacement the tiller was brought back to me for testing. Still grinding, even in reverse. WOW! Sent out again on July 15th for further evaluation. Still awaiting the results. Come on Troy, you have to do better than this! And by the way, I have been using the old horse on occasion to try to keep my gardens looking good. Other than these issues, I hope to use this tiller again. after all, I did buy it to use.

Rated 1 out of 5 by from Very Disappointed Received my Big Red Tiller on 05-15-19 through Home Depot. Spent 3 Hours with Troybilt "HelpLine" to find out how & where to connect the Neutral Safety Switch. Received no definite solution. Later I found that the Battery Tray was improperly installed which did not allow enough clearance to insert the Male connector from the Handle Bars into the NSSw Female Connector. After correcting this Troybilt assembly error I managed to stumble through the very poor excuse for a Product Manual and completed the assembly of the Tiller. While tilling a small Garden Plot I had two Lever Knobs come off in my hand while exerting normal pressure on them. The Tine Engagement Lever was not tightened on the shaft either when delivered. When you attempt to tighten the set screw on the shaft it does not grip well and just loosens with use. After tilling the plot I placed the Transmission in "Fast" Mode to transport the tiller back to my garage. WhenI stopped the tiller , idled down the engine and shut it off the Transmission LOCKED IN FORWARD GEAR-WILL NOT SHIFT INTO NEUTRAL. After searching the Troubleshooting Section of the "Manual" it says to "lube the Motor Mount Bars". Completed-no change in Transmission. Also the Throttle Lever and cable that mounts on the Handle Bars doesn't work -USELESS!!!!! I now have a Brand New Tiller with less than Break In Hours on it that I have nothing but issue after issue with. VERY DISAPPOINTED with the Troybilt "QUALITY" that you advertise to sell your . Products .

Rated 3 out of 5 by from Details are lacking My second Horse. One rim was mounted so that the valve stem is on the inside making it difficult to check air pressure. Throttle cable is plastic and was broke/not working correctly within one month. Plastic knob for throttle on the engine vibrated loose while in loose and is somewhere in one of my gardens. Plastic handle on the Tines/PTO Clutch Lever vibrated loose while in use and is somewhere in one of my gardens. The actual functionality of the tiller is great as also. But given what I spent on the tiller, that I had to put it together and then have these nominal but convenient pieces vibrate off or brake is very disappointing.

Rated 5 out of 5 by from Not many brakedowns I bought this back in 1986 I do believe. It still keeps going. Hardly any issues at all, as long as you keep the care up, it will last forever, at least35 + yrs. and still going strong.

Rated 3 out of 5 by from Not the Original Troybilt This is my second Troybilt Horse model. The drive system and engine is like the first, however, others features are inferior. The clutch lever is made of soft tubular steel design and has bent already from normal use. The tine engagement mechanism has a socket head screw that engages the spline which wore off and had to be replaced. The safety switch system on the handles quite working and I had to repair.
