Who Is the MMS MS550J For?
If you have slopes that a traditional walk-behind mower can’t safely tackle, the MS550J handles up to 45° inclines on rubber crawler tracks — keeping you far from the danger zone.
Large uneven lots, drainage ditches, roadside verges — the MS550J’s crawler traction keeps going where wheeled mowers bog down in soft or sloped terrain.
Add a remote-controlled tracked mower to your fleet. Cut hillsides and embankments safely and efficiently, without crew exposure to slope rollover risk.
Keep rough terrain, berms, and embankments trimmed to standard. Remote control lets one operator manage areas that would otherwise require multiple crew members.
Roadside mowing, highway medians, canal banks, and power line right-of-ways — areas where operator safety on slopes is a liability and efficiency is essential.
Anyone who has worried about pushing a mower uphill will appreciate operating from a safe distance. The remote handles 360° spot turns — just point and mow.

This thing handles my uneven backyard effortlessly. The tracked wheels navigate bumps and slopes that would stop a wheeled mower. Remote control range is solid.

Impressive machine. Cuts evenly and the tracks give it real traction. Takes a few minutes to learn the controls but then it is easy to operate.

Good build quality and it handles rough terrain well. Battery life could be a bit longer but overall it does the job.
