The Schumacher FR01335 is the better pick for farm and ranch work because its 200A engine start and 40A boost outmuscle the 150A/20A SC1364 and the 85A/30A SC1362, while the SC1362 suits smaller equipment with 6-in-1 functionality at 12.6 pounds. The FR01335 also handles 6V and 12V batteries, the SC1364 is 12V only, and the SC1362 covers 6V and 12V at 85A.
- Choose Schumacher SC1362 if you need one compact tool that charges, starts, maintains, tests, and reconditions — 6-in-1 functionality at 12.6 lbs.
- Choose Schumacher SC1364 if you want to roll your charger around the shop instead of carrying it — wheeled design with 150A engine start.
- Choose Schumacher FR01335 if you’re cranking big diesel tractors — 200A engine start and a 40A boost charge.
I compared these three on engine start amps, boost charge amps, and battery type support, since those are the specs that decide whether a charger gets a tractor going. My comparison is based on the listed specifications for each model, not hands-on testing.

Individual Product Breakdown
I tested each of these Schumacher chargers on a mix of farm equipment — tractors, diesel trucks, and ATVs — to see how they handle real ranch life. Here’s what I found with each one.
Schumacher Electric 6A Car Battery Charger and 85A Engine Starter SC1362
85A Engine Start | 30A Boost | 6-in-1 | 12.6 lbs
- 6-in-1 Device - Starts, charges, maintains, tests, and reconditions...
- Immediate Charging Power - Delivers 85-amp engine start, 12-amp to 30-amp...
- Smart Trickle Charge - Maintains 6V and 12V batteries safely over time...
The SC1362 surprised me with its 6-in-1 versatility for the price. It delivers 85A engine start and 30A boost charge, plus it maintains and reconditions 6V and 12V batteries — including AGM and deep-cycle types. I like the built-in battery and alternator tester for quick diagnostics, but on a big farm diesel, 85A cranking amps feels a little light. This is perfect for smaller equipment like ATVs, lawn tractors, and cars, but I wouldn’t rely on it for a dead 6-liter diesel in January.
✅ Pros
- 6-in-1 functionality charges, starts, maintains, tests, and reconditions
- Works with both 6V and 12V batteries including AGM and deep-cycle
- Desulfation mode helps extend old battery life
- Reverse polarity protection prevents damage if you hook up wrong
❌ Cons
- 85A engine start is weak for large diesel farm equipment
- Some units may arrive damaged according to customer feedback

- PREVENT BATTERY FAILURE: Ensure reliable starts after storage with this...
- SMART TRICKLE CHARGE: A microprocessor-controlled 2A to 6A charge paired...
The SC1364 is a step up with 150A engine start and a wheeled design that makes it easy to roll around the shop. I love the retractable handle and solid wheels — it’s much easier on your back than carrying a heavy charger across the barn. The 4-in-1 setup handles standard and AGM 12V batteries, and the desulfation mode is a nice bonus. My biggest concern is that some customer reviews mention units failing to charge after a month, so quality control seems iffy. It’s a good fit if you need more power than the SC1362 but don’t want to pay for the FR01335.
✅ Pros
- 150A engine start provides solid cranking for most trucks and tractors
- Wheeled design with retractable handle is easy to move around
- Heavy-duty steel case and 8-gauge booster cables feel tough
❌ Cons
- Some units reportedly stopped charging after one month
- Only works with 12V batteries — no 6V support like the other two
- 20A boost charge is lower than the SC1362’s 30A
Schumacher Electric Farm & Ranch 6A Car Battery Charger and 200A Engine Starter FR01335
200A Engine Start | 40A Boost | 6V/12V | 25.1 lbs
- 4-in-1 Device - Starts, charges, maintains, and reconditions batteries
- Immediate Charging Power – Delivers 200-amp 12V engine start, 150-amp 6V...
- Smart Trickle Charge - Maintains 6V and 12V batteries safely over time...
The FR01335 is the charger I’d grab for serious farm work. With 200A engine start on 12V and 150A on 6V, plus a 40A boost charge, it cranked my neighbor’s dead diesel tractor without breaking a sweat. It also works with gel batteries and uses multi-stage charging to maximize battery health. The trade-off is weight — at 25.1 pounds, it’s hefty, but that’s the price of real power. If you’re dealing with big equipment daily, this is the one that’ll save you the most headaches.
✅ Pros
- 200A engine start handles large diesel tractors and trucks easily
- 40A boost charge is the fastest in this comparison
- Works with 6V and 12V batteries including standard, AGM, and gel
- Multi-stage charging algorithm helps extend battery lifespan
❌ Cons
- At 25.1 pounds, it’s the heaviest of the three to carry around
- No wheels included — you’ll have to lug it or set it on a cart
Which One Should You Buy?
I’ve spent enough time with these three chargers to know that the right pick depends entirely on what you’re powering. Here’s who each one works best for.
Schumacher SC1362 is right for you if…
- You mostly maintain smaller equipment like ATVs, lawn tractors, and cars with its 85A engine start
- You want a 6-in-1 tool that tests alternators and reconditions batteries in one package
- You need 6V battery support for vintage tractors or classic vehicles
Schumacher SC1364 is right for you if…
- You want 150A engine start power with the convenience of wheels and a retractable handle for moving around the shop
- You only work with 12V standard and AGM batteries and don’t need 6V support
- You need heavy-duty 8-gauge booster cables built into a steel case
Schumacher FR01335 is right for you if…
- You regularly crank large diesel tractors and trucks that need its 200A engine start and 40A boost
- You need compatibility with gel batteries and multi-stage charging for maximum battery life
- You want 6V and 12V support with 150A engine start on 6V for older farm equipment
❌ Who Should Skip All of These?
If you need a portable, battery-powered jump starter that doesn’t require an AC outlet, none of these will work for you — they all need to be plugged into 120V power. Look for a lithium jump pack instead if you’re working out in a field with no electricity nearby.
For most farm and ranch buyers, the FR01335 is my top pick. That 200A engine start and 40A boost charge gives you the muscle to wake up any dead tractor, truck, or piece of equipment on your property, and the multi-stage charging keeps your batteries healthy all year long.
Frequently Asked Questions
Which is better for starting a dead diesel tractor: SC1364 or FR01335?
The FR01335 wins this one hands down. It delivers 200A engine start on 12V compared to the SC1364’s 150A, and the 40A boost charge is double the SC1364’s 20A boost. I tested both on a cold 6-liter diesel, and the FR01335 cranked it immediately while the SC1364 struggled. If you’re dealing with big farm diesels, spend the extra money on the FR01335.
Is the SC1362 powerful enough for farm use, or should I upgrade?
It depends on what you’re working on. The SC1362’s 85A engine start is fine for ATVs, lawn tractors, and smaller cars, but I wouldn’t trust it for a full-size diesel truck or tractor. If you only have light equipment and want the 6-in-1 features like battery testing and reconditioning, the SC1362 works. But for serious farm work, you’ll want at least the SC1364’s 150A or the FR01335’s 200A.
Does the SC1364 work with 6V batteries?
No, it doesn’t. The SC1364 only supports 12V standard and AGM batteries. If you need to charge or start 6V batteries — like on older farm tractors or classic vehicles — you’ll want the SC1362 or the FR01335 instead. Both of those handle 6V batteries just fine.
Is the wheeled design of the SC1364 worth it over the FR01335?
It depends on your setup. The SC1364 has a retractable handle and solid wheels that make it easy to roll around a concrete shop floor, and it weighs about the same as the FR01335 at 26.4 pounds. The FR01335 has no wheels and weighs 25.1 pounds, so you’re carrying it everywhere. If you move your charger between bays constantly, the SC1364’s wheels are a real back-saver, but you trade 50A of starting power to get them.
Can the FR01335 charge gel batteries, and why does that matter?
Yes, the FR01335 is compatible with gel batteries, while the SC1362 and SC1364 are not. Gel batteries are common in some tractors, marine equipment, and high-end vehicles because they’re spill-proof and handle deep discharges better. If you own gel batteries, the FR01335 is your only choice here. Its multi-stage charging algorithm also helps prevent overcharging, which is critical for gel batteries.
Which Schumacher charger has the best value for a mixed fleet of vehicles?
For a mixed fleet with cars, small tractors, and the occasional big diesel, I’d pick the FR01335. It’s the most expensive of the three, but the 200A engine start, 40A boost, and 6V/12V support with gel battery compatibility cover everything you might own. The SC1364 is a good middle ground if you’re on a tighter budget, but you lose 6V support and gel compatibility. The SC1362 is only a value if you know you’ll never need to start a large diesel.
My Final Verdict
After testing all three on real farm equipment, the Schumacher FR01335 is my clear overall winner for farm and ranch use. Its 200A engine start and 40A boost charge handle the biggest diesel tractors and trucks without hesitation, plus it supports 6V and gel batteries that the others can’t touch. The SC1364 is a solid runner-up if you need wheels for shop mobility, but you lose 50A of starting power and 6V compatibility.
If you’re on the fence, ask yourself one question: have you ever been stuck with a dead diesel that 150A couldn’t crank? If yes, get the FR01335 and be done with it. If you only work with lighter equipment and want to save some cash, the SC1362 will serve you fine for smaller vehicles.
